However, the content of this extremely shocking emergency telegram from the North was much more than that.
The main information of the Northern Ministry's emergency call is divided into four points. The first is about oxygen top-blown converter technology, the second is about vertical deep hole drilling machines, the third is the base machinery manufacturing plan proposed by Professor Zhuang Qianding, and the fourth is about Professors Yu Hua and Zhuang's preparations to go there. Site inspection based on location.
If oxygen top-blown converter technology brings shock and unimaginability, then a single vertical deep-hole drilling machine that can process 35 pieces per day breaks the perception.
The total smelting time of a single operation is 30 minutes, and the daily production of 96 tons of steel. It sounds too far away. It is impossible to imagine that such technology exists in the world. As for the technology of processing gun barrels, it is different from the knowledge of the trio. closest.
Making guns has always been the team's goal.
The technical requirements and difficulty of making guns are obvious to all. Nowadays, there are only three arsenals in the country capable of manufacturing firearms, namely Taiyuan Arsenal, Hanyang Arsenal, and Gongxian Arsenal.
If it were placed in 1931, Shenyang could also be added.
The core of making a gun is the barrel.
One is the gun hole, and the other is the rifling.
What is the concept of a vertical deep hole drilling machine that can process 35 pieces per day?
Take the Taiyuan Arsenal, Yan Xishan's lifeblood, which belongs to the Northwest Industrial Company, for example. The peak scale of the Taiyuan Arsenal was during the Central Plains War, with 15,000 employees and 3,800 pieces of machinery and equipment. With such a large scale, the monthly output of rifles was The number reaches about three thousand.
Now, with only three of these vertical deep-hole drilling machines, the monthly output of processed gun barrel blanks can be as high as 3,000 pieces.
It is true that the monthly output of barrel blanks is not equal to the actual output of rifles. After all, it is still limited by the efficiency of rifling marking, but this does not mean that the importance and value of vertical deep hole drilling machines can be ignored.
Once the efficiency of rifling marking reaches the same level, wouldn't it be easy to achieve a monthly production scale of thousands of rifles?
The boss clearly understands the importance of the vertical deep hole drilling machine. His heartbeat is racing and his breathing is trembling. However, this is not over yet. With the rollout of the machine manufacturing blueprint of the base described by Professor Zhuang, it has reached the world's third-rate machinery manufacturing level in six and a half years. The target fell on his heart like a red-hot brand.
He didn't know what the world's third-rate machinery manufacturing level meant, but he knew that if this goal was achieved, the organization would definitely be stronger than it is now.
"Incredible, really incredible. An oxygen top-blown converter with an annual output of 35,000 tons, a vertical deep-hole drilling machine that can process 35 pieces per day, independent research and development of machinery manufacturing equipment, and the establishment of a machinery manufacturing industry. These technologies are connected in series. Together, we built an industrial chain covering steel, machinery manufacturing and ordnance production, plus the sulfuric acid industry and the explosives industry...I suddenly had an illusory feeling, as if this was a dream."
"This is not a dream, but reality. What should we do now?"
"Of course... seize this precious opportunity and call back to the North. First, the organization will immediately raise the remaining funding gap, assist in purchasing materials and machines, and fully support the steel plant plan. Second, the vertical deep hole drilling machine must be protected and shipped as soon as possible.
Resistance to the base area, third, agreed to implement the plan of independent research and development of mechanical equipment and machinery manufacturing industry, fourth, agreed to the request of Yu Hua and Professor Zhuang to go to the base area to inspect the site selection, and asked them to do their best to protect the safety of Yu Hua and Professor Zhuang Qianding, and not to publicize it until
Arrive at the base. After that, in principle, the identities of the two of them are required to be kept highly confidential, but their safety must be ensured."
"I agree."
"I agree."
"In addition, the Japanese army has begun to launch a war. Our term 'pre-war mass production' is a bit inappropriate. I think it can be renamed wartime mass production, which is more appropriate."
"Wartime mass production...good."
…
As orders were issued from the decision-making level, messages were sent to all parts of the country, and the organizational machine with extremely high discipline and coordination entered full operation to carry out organized purchasing activities.
Materials and equipment.
In terms of materials, in addition to the parts owned by the base, important industrial raw materials such as copper, silicon steel sheets, chromium, tungsten, molybdenum, and vanadium need to be purchased from outside.
Among them, red copper, silicon steel and tungsten are placed first. Red copper is used for oxygen lance nozzles and heat dissipation copper tubes, silicon steel is used for high-power DC motors, and tungsten, a rare element, is used as an additive metal to smelt and produce machine tool tools.
Quality alloy - tungsten steel.
In terms of equipment, there are basically no base areas. It is necessary to purchase high-power DC motors, diesel generators and other industrial production auxiliary equipment. There are as many as twenty types, and the quantity of each type is as large as possible.
High-power DC motors are mainly used to drive equipment, with a starting power of 5 kilowatts and a variety of different power specifications. The upper limit of the power specification depends on the limit that can be purchased.
Whether it is the tilting device of the oxygen converter or the turbocharger and turbine compressor of the air separation equipment compressor, they are all inseparable from the power support of DC motors.
If you can buy it in the early stage, buy it. No matter how high the price is, use it first, and then imitate or independently develop it in the middle and later stages.
Thanks to the original 2.98 million silver dollars and gold, the organization in the most difficult period had an original capital that could barely support the operation of the entire plan.
It's not much money, but it's enough.
Southern region, southern Jiangxi, Dayu County.
A hazy drizzle fell from the sky, cooling down the temperature a bit in southern Gansu, which was in full swing in July, and taking away the scorching heat like a fire.
Dayu, also known as Nan'an, is located in the southwest of Ganzhou, at the intersection of Jiangxi, Guangdong and Hunan. This county was originally unremarkable in Chinese history, but it became world-famous because of a mine.
The world is short of tungsten, but China is not. China’s tungsten mines are led by Dayu Xihuashan. This sentence is a common understanding around the world.
Xihuashan Tungsten Mine is the earliest tungsten resource mined in China. It has the highest reserves and excellent quality. Its tungsten production accounts for more than 99% of the country's total tungsten production and more than 80% of the global tungsten production.
Today, 100% of the tungsten sand produced by the Xihuashan Tungsten Mine is sold to Europe. It is one of the few export goods that achieves a "trade surplus" in China's export commodity catalog.
As for these buyers of tungsten sand...
Naturally, Tokusan is extremely short of tungsten.
Tungsten has extremely high application value and role in the military. Armor-piercing projectiles using tungsten alloy as material have significantly improved penetration performance and lethality. This is simply the most ideal material for armor-piercing projectiles.
In addition to the military applications of armor-piercing projectile materials, in the civilian field, carbide machine tool tools based on tungsten alloy are simply perfect tool materials. Their extremely high hardness and wear resistance give tungsten alloy unprecedented performance.
The most interesting thing is... Dayu County, where the Xihuashan Tungsten Mine is located, was once the old Soviet area.
Yes, the old Soviet area.
Today, Dayu County welcomed a guest from Ganzhou City, a special guest with an unusual identity and a batch of gold bars.
