Chapter 304 Facing the bombing of Japanese aircraft, what should we do?
"Papapa!" Immediately afterwards, the heads of the departments applauded and congratulated the birth of the highest-tech group.

The applause was endless. Professor Zhuang and the others were nothing. After all, they had expected it, but Zhao Zhangcheng, who had just arrived from the Liushugou Arsenal, was stunned.

what's the situation?
How can I even get into this supreme science and technology group that looks so good?
Zhao Zhangcheng's face was full of confusion, looking at Chen Kang with doubts and desires in his eyes.

He wondered why...

Feeling Zhao Zhangcheng's gaze, Chen Kang smiled without giving any explanation. After the applause fell, he continued: "Then each department will introduce itself and report the recent situation."

The words fell, and his eyes turned to the chief of the general affairs section sitting on the left.

"Hello, the expert of the highest technology team. I am Lu Yuan, the chief of the General Affairs Section. I am reporting on the responsibilities and recent status of the General Affairs Section. Currently, the General Affairs Section is responsible for the transportation, road construction, and logistical support of each factory and mine."

Lu Yuan, the head of the General Affairs Section, stood up abruptly and saluted the three people facing him: "As of today, there are 490 registered members of the General Affairs Section, including 5 Dodge trucks, 1 German-made red-headed car, and 1 large convertible. A total of 120 horse-drawn carts, 94 mule carts, and 100 bullock carts are all in transit, with a daily capacity of [-] tons. In terms of roads, a Yushen Highway is being built with a gravel roadbed. This is all the information about the General Affairs Division. Please refer to it .”

"Thank you Comrade Lu." Professor Zhuang got up and took the documents from Lu Yuan.

"Hello, Professor Zhuang, and student Yu. I am Hu Zhigang, the chief of the Ordnance Engineering Department. I am reporting the duties and recent status of the Ordnance Engineering Department. There are a total of 160 five people including administrative, technical cadres and workers, an old-fashioned lathe, a vertical deep-hole drilling machine, vise, and several grenade shell molds.”

Hu Zhigang, head of the Ordnance Engineering Section, stood up, raised his hands in salute, and reported on the situation of the Ordnance Engineering Section: "The Liushugou Armory Factory can currently produce wooden handle grenades, and the designed daily output has increased from the original 200 to 600. The actual daily output is limited by gray. The supply of imported pig iron is insufficient, only 30 pieces."

"The Ordnance Engineering Department is organizing research on the official rifle project and the [-]mm mortar project. It is expected to complete the imitation task of the [-]mm mortar within three months and enter the stage of mass production. The imitation production of the official rifle will be completed within one year. , This is all the information about the Ordnance Engineering Department, please take a look at the highest technology group."

"Thank you, Comrade Hu."

Professor Zhuang thanked again and took over the extremely important military production materials in the base area.

After Hu Zhigang sat down, the remaining three departments of the Military Industry Bureau spoke one after another to report the situation.

"The Public Works Division has jurisdiction over the electric furnace steel plant, sulfuric acid plant, petroleum plant, blast furnace iron plant, coking plant, and a total of 280 workers and technical cadres in each plant. The electric furnace steel plant produces 240 kg of electric furnace steel per day, with an annual output of about 88 tons. The plant produces 9.5 tons of sulfuric acid per day, the oil plant produces 1.2 tons of oil per day, and refines a total of 500 liters of gasoline and diesel.

"The Explosives Division has a Fire and Explosives Factory with 84 employees. It can produce single-base propellants, double-base propellants, and heavy explosives. The daily output has increased from 300 kilograms at the beginning of the factory to 450 kilograms now."

"The Mineral Resources Division has [-] mines under its jurisdiction, including Shenmu Coal Mine, Shenmu Iron Mine, Yimeng Crystalline Graphite Mine, Jingbian Copper Mine, and Yulin Limestone Mine. They can independently supply iron, copper, coal, oil, natural gas, limestone, Forty raw materials such as quartz sand, graphite, alkali, Glauber’s salt, salt, boron, phosphorus, etc., the mining volume and related data of each mine are here, please have a look.”

Through the general information given by the five departments of the Military Industry Bureau, Zhuang Qianding and Yu Hua now have a basic grasp of the overall situation of the entire wartime production plan.

After the voice of the person in charge of the Mineral Resources Section fell, Zhao Zhangcheng, who was sitting in the last seat, fell into a daze. Looking at the crowd, he didn't know what to do.

Aware of Zhao Zhangcheng's reaction, Chen Kang did not rush to announce that he had entered the stage of discussing the location of the steel plant, but signaled him to speak: "Comrade Zhao, can you briefly talk about the progress of the 60mm mortar project, which is highly valued by the headquarters , after all artillery is very important to us."

The 60mm mortar project has received great attention from the headquarters. Although the official rifle is very important, the artillery is even more important.

Hearing Chen Kang's explanation, Professor Zhuang Qianding and Yu Hua nodded to express their understanding.

"Dear leaders, experts from the highest technology group, the design drawings of the 60mm mortar project have been completed, and the factory organizes workers to process and manufacture the prototype gun, but we have encountered a big problem in the barrel. We can't handle the 60mm seamless steel pipe. "Zhao Zhangcheng stood up nervously, recalling the development experience and learning process in the arsenal during this period of time in his mind, sorted out his words a little, and quickly reported the current status of the project.

When the words fell, he sat down immediately.

Now, with the help of the artillery experience provided by Zhao Zhangcheng, the 60mm mortar project of Liushugou Arsenal has completed all the designs and entered the actual manufacturing process. However, how to manufacture seamless steel pipes has become a stumbling block for the technicians and workers of the arsenal. biggest problem.

How to make a barrel with an inner diameter of 60 mm?
Zhuang Qianding listened to the situation, pondered for a while, turned his head to look at Yu Hua, and said: "About this issue, after the meeting, Yu Hua and I will go to the arsenal to find out whether it is difficult to manufacture medium-caliber seamless steel pipes. It's not difficult and it's difficult."

There are two ways to manufacture mortar tubes, one is the rolling seamless steel tube process, and the other is the boring process of the barrel blank. Considering economic factors, the former is usually selected. After all, the barrel blank is bored. The cost is more than several times that of the former. Only the barrels of high-pressure guns such as howitzers, tank guns, and cannons will be bored with barrel blanks.

The seamless steel pipe rolling process is divided into hot rolling and cold rolling. The mainstream process is hot rolling, and there is basically no cold rolling process in China.

Sensing Professor Zhuang's gaze, Yu Hua understood what he meant and took this matter down in his mind.

"Thank you, Professor Zhuang." Zhao Zhangcheng was taken aback when he heard these words, and was immediately overjoyed, and thanked him quickly.

Zhuang Qianding shook his head: "You're welcome."

……

"Okay, now we're starting to discuss the location of the steel plant. Professor Zhuang, I want to know the suggestion of the highest technology group. This is the map of the Shaanxi-Gansu-Ningxia base area." After the report on the recent status of the [-]mm mortar project was completed, Chen Kang announced the topic of today's meeting, then took out a map and put it on the table, looked at Professor Zhuang, and asked.

The heads of various departments in the conference room cheered up and turned their eyes to the highest technology group directly opposite.

"The site selection of steel plants generally requires that it be as close as possible to the source of raw materials, with convenient transportation and flat terrain. Taking into account the factors of war, it should meet the requirements of places that are easy to defend and difficult to attack. After discussions and discussions with Yu Hua, three places were initially determined, Yulin , Jingbian, Mizhi." Zhuang Qianding and Yu Hua looked at each other, then looked up at the map of the border area in front of them, pointing their fingers at three different places.

Chen Kang was thoughtful, respectfully said: "Professor Zhuang, can you explain in detail?"

Zhuang Qianding heard the words and cast his eyes on Yu Hua.

"Director Chen, comrades, Jingbian is located in the northwest of Yancheng, borders Yikezhao League, and is backed by Hengshan. The territory is rich in water resources, and there is Jingbian Copper Mine. , or building railways in the future, it will be very convenient.”

Yu Hua took advantage of the situation and slowly gave the reasons and advantages and disadvantages of choosing Jingbian: "Military, if the Japanese army wants to attack Jingbian, they must choose to cross the Yellow River from the northwest of Shanxi, cross Luliang and Hengshan, or cross Suiyuan Baotou. The Yellow River, then Yikezhao League and Yulin."

Hearing Yu Hua's analysis, everyone present nodded, and Lu Yuan and Chen Kang, the heads of the general affairs department who were former combat staff officers, gave a positive attitude.

Shaanxi is located in the Loess Plateau, with complex terrain, vertical and horizontal mountains, and extremely inconvenient transportation. The difficulty for the Japanese army to attack the northern Shaanxi base was more than ten times that of the plain area.

"Compared with Jingbian, Yulin is closer to Yikezhao League, backed by Hengshan Mountain, rich in water resources and mineral resources, about 80 kilometers away from Shenmu, and geographically located in the middle of the three places. The supply of various industrial raw materials is very convenient, and the supply of raw materials The road and railway construction conditions in the area are excellent, and the military is similar to Jingbian, relying on Luliang and Hengshan as natural barriers, but because it is closer to the Ikezhao League, the security is slightly lower than Jingbian.”

Yu Hua continued, pointing to Yulin with his right hand: "Actually, from an industrial point of view, Yulin is the most suitable place for industrial development among the three locations. In the future, Yuyi Industrial Zone can be established relying on the Yikezhao League."

The development potential of Yulin is extremely profound. On the left is the Jingbian Copper Mine, on the right is the Shenmu Coal and Iron Mine, which produces limestone and quartz sand and other minerals, and to the north is the super raw material base Yike Zhaomeng, which can accommodate 500 million tons of steel per year. industrial area.

Hearing the reasons and advantages and disadvantages given by Yu Hua, everyone turned their eyes to Yulin at the same time. Unexpectedly, this seemingly ordinary place has so many advantages.

"Where's Mizhi?" Chen Kang asked.

Yu Hua said: "The advantage of Mizhi is that it is in the middle of the mountains, the safety is the best, it is close to Shenmu and Yulin, and it has abundant water resources and natural gas resources. The disadvantage is that it is small and has insufficient development potential. And the construction of roads and railways is very difficult. My speech is over, thank you all.”

Mizhi is surrounded by the Hengshan Mountains, next to the Wuding River, and is rich in water and mineral resources. However, the area of ​​this place is not large, and it is barely enough to accommodate a 3.5-ton steel plant. It is basically impossible to expand it in the future.

As Yu Hua dragged out the reasons for the choice of the three places and their advantages and disadvantages, the conference room fell into silence, and everyone present except Professor Zhuang was lost in thought.

Jingbian...

Yulin...

Rice fat...

"Deputy Team Leader Yu, I have a question." At this moment, Lu Yuan, the person in charge of the General Affairs Section, suddenly raised his hand and issued a message.

Yu Hua responded, "Section Chief Lu, please tell me."

"Faced with the bombing of Japanese aircraft, what should we do?"
