I Have Become A Military Industry Boss And You Tell Me To Start School?

Chapter 195 The true meaning of armor!

Facing An Ran's doubts, Chen Fang looked clear.

"Actually, what I sold to Ellia was not an ordinary T-72, but a T-72B." He said calmly.

The T-72 is so classic that there are dozens of derivative modifications.

Among them, the T-72B is the second important modification. It has changed the sight and installed a new engine, thus having the aiming ability, accuracy and maneuverability that are not inferior to the T90.

The only difference in appearance between the T-72B and the original T72 is that there is a neutron protection layer on the top to prevent nuclear strikes.

This detail can easily be overlooked, and after undergoing various magic modifications, many features have been confused.

An Ran nodded in understanding. She really didn't understand the T72 variants. To be honest, even an expert in this field couldn't tell which variant was different.

But she knows one thing, that is, even if the T72 can upgrade its mobility and fire control system, its armor is still its biggest shortcoming. Even if it is welded with external armor and reactive armor, it cannot reach the level of today's main battle tanks.

No matter what, it is impossible to achieve the comment of "not much different from M1A2".

After all, the M1A2's protective capabilities are obvious to all. The incident of fighting each other on the battlefield of Iraq until there were no shells is still a vivid memory in An Ran's mind.

"What about the armor? How did you modify the armor?" She looked into Chen Fang's eyes and asked.

"To be honest, I didn't modify the armor." Chen Fang said with a smile.

"Do you know what is the most critical factor affecting a tank's protection?" he asked rhetorically.

"have no idea……"

An Ran was startled for a moment, then shook his head blankly.

"It's the armor that has to be uniform and pure."

Chen Fang looked at the confused An Ran, smiled slightly, and spoke the answer.

"If the armor is uneven, it will inevitably cause the armor steel plate to fail to meet the requirements."

Chen Fang said: "Asan's Arjun series is exactly like this."

Although the fire control system of Asan's Arjun tank is very powerful, the level of tank armor production by the tank factory is really unsatisfactory, and the precision and accuracy of many arts and crafts do not meet the standard requirements.

The armor plate pressed out in this way must be very uneven and cannot reach the theoretical penetration resistance value at all.

This is the reason why the Arjun tank clearly combined technologies from various countries, but the final assembled product was hoisted and beaten by Batie's Modified 59.

Chen Fang opened his mouth to explain.

"So that's what it is..."

An Ran on the opposite side was obviously a little stunned.

"As for the purity of the armor, let alone that."

Chen Fang continued to speak.

"In the process of making armor, most of them use homogeneous steel armor. It is necessary to ensure that the chemical composition, metallographic structure and mechanical properties of the homogeneous armor have a stable ratio.

Only the armor produced must have sufficient hardness. "

In fact, with the development of the steel industry today, the production of various steel plates has become a precise operation similar to chemical experiments. The proportion of ingredients in a steel plate has a very precise value.

Ultimately, the purpose of adding these ingredients is to make the so-called single-phase austenite composed of iron molecules inside the steel plate have higher strength, or to form multi-phase austenite that is more stable and stronger than the single phase.

This is why even if you get someone else's sample, you can't learn the technology through component analysis, because the process and ingredients are too precise, so precise that it's impossible to get a value through analysis.

"In addition, various impurities will seriously affect the strength of the steel plate."

Chen Fang said.

"If excessive impurities penetrate into the armor, then the steel armor will become a piece of waste."

"This kind of armor can also be as brittle as paper. For example, the British cruise tank A9 during World War II was often defeated by a single shot when faced with attacks by Prussian Tiger tanks.

"In addition to the Tiger tank's 88mm main gun, another reason is the uneven armor of the cruise tank A9, which makes its armor more fragile than before."

Chen Fang continued to speak.

"Therefore, the armor is uniform and pure, which can greatly affect the tank's ability to resist body penetration."

"In order to produce uniform and clean armor, an armor steel plate needs to be continuously pressed 30,000 times under a 2,000-ton hydraulic press to meet the standard."

Chen Fang said.

An Ran on the side nodded.

She understood what Chen Fang said. The simplest analogy is the difference between steel and iron.

In ancient China, there was a saying called "steel can be made into steel by one hundred refinements", which means that a piece of iron needs to be refined and forged more than a hundred times before it can become steel.

...--.***..........

This is because too much carbon and sulfide in iron will greatly affect the strength of austenite. It requires multiple forgings and combustion and oxidation to make a piece of iron purer.

Become steel.

"I have seen the process of making steel plates before. They are all large steel ingots. After being heated to high temperatures, they are all burnt red.

"Under the huge pressure of the hydraulic press, everything was pressed into a steel plate of only a few millimeters."

"It's very picturesque."

Chen Fang smiled.

"However, even after high-temperature pressing, there is still no guarantee that the steel plate will be completely uniform and without bubbles."

"There is no guarantee that there will be no impurities at all."

.......0

Chen Fang said.

"It's too difficult to make armor..."

An Ran couldn't help but sigh and suddenly his eyes widened: "Then why is the Ì72's armor more powerful than the M11?"

Seeing An Ran who was a little confused, Chen Fang couldn't help but smile.

"Just because others can't do it, doesn't mean I can't do it!"

Chen Fang said with a smile.

"Because my military factory can guarantee 100% error-free, and of course there will be no impurities!"

"Furthermore, another key point is that the T72 uses composite armor with a layer of quartz sand in the middle to act as a buffer and dissipate impact.

"The shape and uniformity of quartz sand also greatly affect the T72 armor effectiveness!"

"Theoretically, the rounder the shape of the quartz sand and the more uniform the size, the better the effect. But no one can do this."

"You mean, your military factory is 100% error-free, including these fine quartz sands?"

An Ran's face was full of shock.

"Of course!" Chen Fang confirmed An Ran's suspicion and continued to speak.

"Not to mention monkey versions like the M1A1 and T90, even the composite armor of the M1a2 is only less than 20% more effective than the T72 I produced."

"With the technology to make the equipment impurity-free, and using contemporary smelting methods, the T72 can completely make up for the gap with the M1a2 composite armor!"

Chen Fang said.

After all, the real strength of the M1a2 tank is the depleted uranium sandwich!.
