Chapter 364: If you have money, pursue perfection; if you don’t have money, just do enough!
Ten minutes later, as the thinking computer completed the calculation verification of the last set of data at a speed of 300 million times per second, the initial design plan of the 1.5-ton single-column electroslag remelting furnace was presented in the mind in a three-dimensional form.
The internal structure of the furnace body is clear, and the main circuit and supporting electrical equipment are all available. After mathematical verification, the smelting work can be successfully completed and cutting-edge gun steel materials that meet the mechanical performance requirements can be produced.
The gun steel material of this era basically uses high-quality alloy steel with low sulfur and low phosphorus. Although alloy steel that has not been refined twice can meet the mechanical performance requirements of large-caliber artillery, the life of the barrel is generally not high.
If calculated in seconds, the barrel life may be less than one second, and in terms of rounds it only lasts 200-300 rounds.
If electroslag steel refining by electroslag remelting is used as the gun steel material, the life of the gun barrel will achieve a qualitative leap, reaching more than 600 rounds. Supplemented by the barrel self-tightening technology and the barrel chromium plating process, the life span can be
Up to three seconds!
Less than one second to three seconds, this is the role of electroslag remelting.
After completing all the calculation and verification work, Yu Hua felt a slight dizziness in his head. This was a side effect of high-intensity calculations. He relaxed his mind, gently rubbed his temples with his right hand, and let the golden mathematical symbols relieve the side effects and entered a state of rest.
After resting for a while, the dizziness subsided like a tide.
"Huh, it's basically done. The design work is over. Next, we will enter the test furnace manufacturing process. The 1.5-ton electroslag furnace is enough for the base. One furnace of electroslag steel can meet the needs of two gun barrels." After a short break.
, Yu Hua carefully checked the initial design of the 1.5-ton electroslag furnace, confirmed that it was correct, and thought silently in his heart.
It’s done.
Yes, it's basically done.
From a project research perspective, with the release of the 1.5-ton electroslag furnace design plan, the electroslag remelting technology project has made a major breakthrough. The research progress has come to an end, and the remaining work is nothing more than manufacturing a test furnace.
It has taken several months from proposing the concept of electroslag remelting technology to completing the design plan.
Now, the dawn is approaching.
China is about to smelt the world's first furnace of electroslag steel and has the ability to independently produce cutting-edge gun steel materials, even though this 'production capacity' is most likely to be one furnace per month.
This is another historic breakthrough from zero to one, and the significance and importance of this breakthrough are far more substantial than the achievement of smelting ballpoint pen tip steel in later generations.
After Yu Hua finished thinking in his mind, he picked up the tea cup next to him with his right hand and took a sip. Then he found a blank design drawing, picked up pens and tools with both hands, and began to convert the 1.5-ton electroslag furnace design plan in his mind into design drawings.
The drawing process is familiar, efficient and fast.
About an hour later, the complete design plan for the 1.5-ton electroslag furnace was released, with a total of sixteen drawings.
"Done." The drawing work was completed. Yu Hua carefully rechecked the drawings to confirm that there were no errors in each marked parameter.
The design blueprint is very important. If you make a mistake, it will cause irreparable losses.
After the re-examination of the drawings was completed, Yu Hua felt relieved. He picked up the already cool teacup and brought it to his mouth, taking a sip.
"Dong dong!" At this time, the cave door knocked gently.
"Please come in." Yu Hua put down his tea cup and responded.
The figure who pushed the door open was Zhu Rui. His steps were hurried, showing the efficiency and ability of a soldier. However, he had a pair of panda eyes, which were bloodshot and his face looked haggard.
"Hello, Comrade Zhu." When Yu Hua saw Zhu Rui, he smiled and nodded to say hello, without any official airs.
"Team leader, this is the design plan for the 105mm artillery shell system. I will imitate the Soviet artillery shell design according to your requirements. See what needs to be modified." Zhu Rui quickly came to Yu Hua, raised his hand in salute, and then put it down.
Designed sealed barrel with top secret printed on the surface.
Using Soviet artillery shells as the imitation target, develop a domestic 105mm artillery shell system. This is the task assigned by Yu Hua to Zhu Rui. After the project was established and grouped, Zhu Rui was mainly responsible for this matter. During this period, Yu Hua occasionally gave guidance and provided technical support and data calculation support.
.
"So fast?"
When Yu Hua heard this, he didn't expect Zhu Rui to take out the draft so quickly. Calculating the time, it was only half a month, but seeing Zhu Rui's haggard look, he felt a little understanding.
If nothing else, Zhu Rui probably hasn't had a good night's sleep for a long time.
Without wasting time, Yu Hua opened the design sealed bucket, took out the design drawings placed in it, spread them out and laid them out. Two similar 105mm ammunition design drafts came into view.
The first ammunition model is high-explosive-1, a complete ammunition, with specifications of 105 mm × 380 mm, total weight of 15 kg, muzzle velocity of 580 meters, conventional high-explosive projectile structure, projectile material high-phosphorus steel, TNT charge 2.8 kg,
The theoretical absolute killing radius is 8 meters, and the effective killing radius is 20 meters.
The second ammunition model deflagration-1 is a complete ammunition with a caliber of 105 mm x 380 mm, a total weight of 15.5 kg, a muzzle velocity of 580 meters, a conventional projectile structure, a TNT charge of 2 kg, and the main fuel is thermite.
The theoretical absolute killing radius is 7.5 meters, and the effective killing range is 25 meters.
The designs of the two types of ammunition designed to effectively kill the enemy were clear at a glance. Yu Hua looked serious, then took out the manuscript paper and pen, and began to perform calculation verification, carefully examining every design parameter and local design with the most stringent attitude.
Rigorous and demanding, these are the basic requirements for engaging in military research, and there is no room for error.
Once you make a mistake, the consequences will be disastrous.
This thing is a real artillery shell. If a safety accident occurs due to incorrect design parameters, it is very likely to cause dozens of casualties.
Zhu Rui stood aside, holding his breath, like a student waiting for the teacher to rewrite his homework, with a solemn look on his face. Although Zhu Rui had received complete modern artillery training and achieved the first place in double materials, in the field of weapons and equipment research
, he is still just a freshman who has just started.
Whether the 105mm artillery shell system can pass the test is entirely decided by Yu Hua alone.
Of course, he was still confident in his design plan. After all, it was not an independent development, but a copy based on the Soviet army's standard artillery ammunition.
It is a bit difficult to let him innovate and let him copy homework...
It’s just a matter of basic skills.
Time passed by, and there was silence in the cave, except for the faint sound of the pen scratching the manuscript paper and performing calculations.
The atmosphere is slightly depressing.
After more than ten minutes, Yu Hua finished the second replay calculation in his mind and completed the review of the two ammunition design plans. He then nodded to Zhu Rui and gave approval and affirmation: "Comrade Zhu, the design plan is very good, there are no problems.
If it meets the requirements of the indicators, it can enter the prototype bomb trial production stage."
"Huh..." After hearing this result, Zhu Rui's tense mind finally relaxed.
Fortunately, it worked and passed smoothly.
"If you have no other opinions, I'll sign and seal it here." Yu Hua said with a smile. Although this 105mm artillery system plan has many shortcomings, it can already meet the combat needs of the Eighth Route Army.
If you have money, pursue perfection; if you don’t have money, just do enough.
No matter how poor the performance is, it is still a 105mm caliber artillery shell, and there is no problem in destroying an infantry squad in the skirmish line with one shot.
"No." Zhu Rui shook his head repeatedly.
"Comrade Zhu, here, you have to hurry up on the prototype bomb trial production and test and finalize it as soon as possible, so that we don't face the dilemma of having artillery and no ammunition." Yu Hua nodded, signed the end of the design plan with a pen in his right hand, then opened the drawer and took out the Military Industry Bureau
The equipped exclusive red seal was stamped at the signature position and finally handed to Zhu Rui.
According to the standard process of later generations, confirming the design plan would inevitably require three or five meetings, but now is the war era, and there are not so many restrictions.
One word, fast.
The Japanese invaders were approaching day by day, and they would not be left with much time.
"I understand, but there are too few available manpower and I can't handle it at all. Next, I have to be responsible for the development of the 40mm artillery shell system and the 12.7mm bullet system. I want to split myself in half and use them." Zhu Rui heard this.
After saying this, he nodded helplessly.
Hearing these words, Yu Hua shook his head slightly. Regarding the shortage of talents, he expressed that he was powerless and could only hope that the students invited by Professor Zhuang's letter would arrive at the base as soon as possible.
If you can come together, you can share the research pressure and workload and improve efficiency.
The shortage of talents is a true reflection of the current heavy weapons project team and various departments of the Military Industry Bureau. Among them, the heavy weapons project team is particularly serious. Engaging in the development of advanced weapons and equipment does not require a solid mechanical engineering professional foundation and rich knowledge reserves. This kind of
In later generations, conditions were common on the streets, but nowadays, they are really rarer than giant pandas.
It is not new within the Military Industry Bureau to hold the position of director of a factory with a primary school education.
After I leave the base area, the shortage of talents will become even more serious.
"Report!" At this moment, guard Lu Junyu's voice came from outside the cave door.
Yu Hua responded: "Please come in."
"Sir, the director asked you to return to the headquarters immediately, saying that Professor Zhuang's students are here." Lu Junyu pushed open the door and came quickly, bringing good news.
Professor Zhuang’s students are here?
At this moment, Yu Hua and Zhu Rui's eyes suddenly brightened.
