Artillery is known as the king of the army, is the embodiment of the current power of a country, the production of cannons is a very large system engineering, it can be said that at present, the whole world, the countries that can produce cannons, there are only a handful, small-caliber guns are a little more, large-caliber cannons, and even the main guns on battleships, is the crystallization of a country's industry, in the United States before the Great White Fleet, many battleships' main guns are directly imported from Britain, and they gradually have production capacity.

Baotou now, there are a series of factories, but also has a certain industrial production capacity, but cannons, basically unlikely, from a certain process dù above, to have drawings to manufacture, has gone a lot, conservative estimates, with drawings, go all out and invest, these excellent workers, after three or four months of exploration, should be able to get some cannon production methods, and even produce qualified cannons, but now, Baotou does not even have drawings of cannons.

Is it difficult to rely on the existing physical object, to explore, this is a little too difficult, reverse engineering is not easy to complete the work, there is no way to use the all-in-one machine, for any country, is a very difficult problem to solve, not to mention the foundation of the barren Baotou.

It is easy to get a task, or a task that is relatively easy to solve in Yang Yuanzhao's view, only 5 task points, and the difficult one is the monthly output of 5 cannons, but it can save more than a month's time. Don't let it go.

What to do, Yang Yuanzhao fell into deep thought. Suddenly, his eyes lit up. There is a kind of cannon, which does not seem to be so difficult, has a simple structure, and can be produced even by ordinary handicraft workshops, which seems to be a way to open the dilemma of Baotou.

Yang Yuanzhao immediately went to the archives on the first floor and flipped through the list of products, hundreds of thousands of tons of items, and all kinds of machine products, all of which had been transported to Taiyuan by water. Through the Taiyuan to Baotou highway, a steady stream of transportation to Baotou, now, the industrial zone has built a large house, are used as warehouses, to load these things, most of them are metal machine qì situation, wind and rain, very soon. The machine turned into a pile of scrap metal.

From Germany, the main import is second-hand machinery, Germany is currently doing industrial upgrading, as a late-developing industrial country. Relying on science and technology, it has completed the overtaking of the old industrial power Britain, and Germany attaches great importance to the role of science and technology in the field of production. The frequency of industrial machine replacement is relatively high, generally 10-15 years. A replacement will be completed. The main imports from Germany are second-hand equipment, as for the United States. There are only a few sporadic industrial machines, which can be a supplement to the Baotou industry, and the rest are raw materials, various types of steel plates, rails, and even special steels, the latter of which is even more huge.

Finally, in the long list of dozens of pages, Yang Yuanzhao found what he was looking for, seamless steel pipes.

The seamless steel pipe of this era is mostly used in the laying of oil pipelines, and in some chemical plants, there will also be a certain use, the steel production in the United States is huge, and the seamless steel pipe is also an important product of it, but compared with the relatively wide oil pipeline, Yang Yuanzhao's customized seamless steel pipe is mainly 50mm, 60mm, 70mm standard, so that the steel pipe is relatively thin.

Such a relatively small seamless steel pipe, mostly used in chemical plants, the output is insufficient, fortunately, Harpy spent a lot of money, ordered from several steel plants, and finally purchased almost 340 tons of seamless steel pipes, almost tens of thousands of seamless steel pipes, enough to occupy a large cargo ship, the cost of transporting back, is very amazing.

I took a look at the storage place of seamless steel pipes, and it was in warehouse No. 21, where some raw materials were stored, and the steel plates, steel bars, and even rails imported from the United States were stored in that warehouse.

With Da Han Xiao Han and a few other long followers, I found the key to the warehouse management and opened the No. 21 warehouse, which is huge, thousands of square meters of huge warehouse, and there are all kinds of metals in a miscellaneous manner, not for a long time, and there is a warehouse to cover, but a strong rust smell, which makes people slightly uncomfortable.

Turning around in the warehouse, the seamless steel pipe is placed in a corner of the warehouse, which seems to be well kept, not only placed in different categories, but even covered with plastic film, compared to other things, the protection is quite good.

Yang Yuanzhao nodded slightly, and said to Changsui: "Take this, this, this, and all of them and take them to the real room!" ”

Seamless steel pipe is steel, the thickness of the seamless steel pipe is smaller, the weight of each one is not heavy, about 10 meters of one, only a few dozen kilograms of appearance, compared with ordinary steel, it is much lighter, find a cart, fix more than a dozen seamless steel pipes, and go to the real room.

In the real room, there is a small machining workshop, 10 or so fitters, are busy there, fitters with the help of machine tools, can process most of the parts, the equipment in the real room is very complete, but the whimsy of scientists, sometimes think of a kind of equipment, must be realized with the help of fitters.

Later, under the mention of several scientists, in the end, this workshop was established, and more than 10 excellent fitters were specially dispatched to serve the real room.

"Let's stop for a moment, there's a task for everyone!" Yang Yuanzhao simply put the mortar in some situations, the mortar is relatively simple, as long as there is a firing pin, and then use a fixed seamless steel pipe and base, the general handicraft workshop, can be processed, welded to complete.

Based on seamless steel pipes, the mortars derived from them have not yet become popular in the world in this era, but in the future in World War I, in the face of trench warfare and group confrontation, mortars as firepower below the regiment can definitely be or shine, flexible and mobile, small in weight, can move with the infantry, which makes him brilliant, not to mention, the power of the mortar is not small at all, in the contact station and charge operations, far greater than the rear firepower to support the infantry.

Mortars need time-delay fuses, as well as higher quality explosives, and today with the invention of high-efficiency fuzes and yellow se-fried yao, there is already the possibility of producing them, and the point is that no one thinks of this. Yang Yuanzhao, as such a person, not only thought of this, but also used it.

Looking at the seamless steel pipe in his hand, the fitter's face showed some strangeness, it looked round, and the diameter was not large, according to what Yang Yuanzhao said, just cut them into different lengths, and then find the steel plate, and get a base for him, of course, the base will be welded with a firing pin.

Yang Yuanzhao is not an expert in weapons, what he can rely on is only some impressions and senior understanding, and the one he came up with is more similar to the grenadier canister of later generations, using the medicine bag at the bottom to stimulate the lead under the impact of the firing pin, and then the medicine bag explodes to produce a huge thrust, and then pushes the cannonball out.

Because the structure is simple, just a gun body and bracket, aiming device and the like, there is no at all, you can wait for later development, later generations, the Japanese army's grenadier canister, is also a completely absent sighting device, but it is used more, practiced, the Japanese army's skilled gunners, can point where to fight, for the infantry support firepower, is a sharp weapon.

The artillery mount is simple, skilled master, after groping, it came out in a few days, but the cannonball has become a big problem, Yang Yuanzhao is also flipping through the task every day, the task is not marked out, whether Yang Yuanzhao has passed the task, the number of cannons has not been reached every day, whether the cannonball has not been made, or other reasons, Yang Yuanzhao can't take care of it.

The chemical real room, specially listed a real munitions room, a new topic, has been arranged a few days ago, the production of new artillery shells.

This is a new task, ranked at the forefront of all tasks, a certain amount of dù above, is the highest reward offered, along with the operation of the real yàn room, in addition to the reward of money, daily necessities, houses, and other ways of reward, so that the whole incentive mechanism is relatively perfect, once the task is announced, soon, someone will accept the task.

Obviously, this task related to military use, most engineers and chemical plant personnel in the United States, have dabbled in the military, and it does not seem to be difficult, but many engineers can't figure out why, there is a fuse and a fuse that touches the ground. Isn't that a bit of a waste?

In Baotou's real room, many times, similar problems will arise, some problems that seem to be unrelated or even clueless, and when integrated, they are a new task.

The basic principle of artillery shells is not a difficult problem for the engineers of this era, especially those who have spent time in military factories, as long as they try a few times and choose the right body and gunpowder for internal refill.

Huang se fried yao has a considerable stability, will not be detonated by the temperature and impact of the explosion, the head of the contact firing pin is relatively easy, adjust the force, with a certain strength of cast iron to make an abrasive, it's OK, under the ordinary collision, it is difficult to make the cast iron broken, once the high speed from the air to the ground, at least at a height of more than 100 meters, and a considerable initial velocity, will hit the damage, so that the firing pin really plays, so that the cast iron cannon body, killing.

The overall concept is this, the mortar team in the Baotou real yàn room was quickly established, and under the tilt of various resources, they not only had various types of flowering shells and shells as research, but even some grenades and bullets were also brought over, and the preparation was enriched, and the research quickly broke through.
