"How's the rest of the research going? For example, knives, models, etc., and the tungsten steel alloy I said was made? "About tungsten steel alloy is also an alloy that Chu Nan is most concerned about.

Tungsten steel, also known as tungsten carbide, refers to a sintered composite material containing at least one metal carbide. Tungsten carbide, cobalt carbide, niobium carbide, titanium carbide and tantalum carbide are common components of tungsten steel.

It has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance, corrosion resistance, especially its high hardness and wear resistance, which remains basically unchanged even at a temperature of 500 °C, and still has a high hardness at 1000 °C.

Once this kind of alloy steel is studied, it is to make knives, which can be used for cutting, drilling, etc. on all kinds of steel, and this kind of processing is related to the design and consumption of machine tools, which can be said to be a ring and a ring, even if Chu Nan can get the knowledge of making these things from the dream, it is very difficult to do it in one step.

After all, this world is too primitive, there are many things, and it needs to be improved step by step, only by establishing a complete industrial system and having a sufficient industrial population can it develop rapidly, and every link may limit the development speed of the entire industry.

"The research on tungsten steel alloy is in another laboratory, and it has been going on, please come with me." Tie Niu showed a confident look, it seems that tungsten steel alloy research has made great achievements.

Seeing Tie Niu's expression, Chu Nan's heart moved, and he said softly: "Tie Niu, don't take tricks, take one step at a time, and move forward steadily, you know?" It is necessary to do a good job of basic research and record it well, which is very useful, and will even affect the development of the next few hundred years. ”

Speaking of which, we have to talk about basic industry and basic science, many things cannot be shortcuts, leapfrog development, although in a short period of time, the speed of development is very fast, in the long run, because the foundation is not solid, development to a certain height, will encounter a great bottleneck, or even stagnation.

This is like building a high-rise building, if the foundation is not good, how can it be possible to build a high-rise building? If you insist on building, there is only one final result, the building collapses and people die, it is better not to build it.

There is another reason, which is the reason why Chu Nan does not want the clansmen to take shortcuts, because once they take a shortcut, people will have a fluke mentality, and they will not even move forward steadily, but always look for shortcuts, which will still bring very serious consequences, and it will be very serious, and it will also bring huge disasters.

"I've emphasized to you many times, basics, you must pay attention to basic research, you know? Don't try to take shortcuts, once you take a shortcut, it can even bring devastating disasters later, remember. Chu Nan taught earnestly.

Tie Niu and the others nodded in response: "Please rest assured that the leader will definitely do his work in a down-to-earth manner, and will never be opportunistic and disappoint the leader." ”

After a while, a few people came to another research room, compared with the research room just now, the layout is basically at a glance, not much different, but here is mainly to study tungsten steel alloy, there are also many finished products in it, in addition to the finished products, there are some tool models, placed on the wooden shelf.

Because there is no machine tool yet, there is no relevant knowledge, and Chu Nan is not ready to teach it at this stage, so it can only be placed here, and it cannot be equipped for use.

Chu Nan picked up a knife and looked at it, it was very delicate.

This is all thanks to the Iron Bull's ability, which can not only control the temperature, but also shape the melted thing according to his mind, so that he can naturally melt all kinds of metals with high melting points at any time, and let them slowly form the shape they want.

This ability of the iron bull can be said to be prepared for the future industrial mechanization, although Chu Nan does not want to let the clansmen enter this step so quickly, but the technical reserves still have to be done, especially now, let the iron cow manufacture some industrial machine tools, even if the iron bull is not there in the future, can continue to manufacture industrial machinery.

"Very good, very good, after a while, I will give you some drawings and samples, you can make some for me, but don't worry, wait for your ability to improve some, we will talk about these, what you have to do next is to continue to study alloys, this is the foundation, there is no qualified metal, and it is impossible to manufacture qualified machine tools."

There is another reason why Chu Nan does not develop machine tools now, that is, with the power of his current faith, he cannot extract such a complex thing from the dream, especially the machine tool known as the industrial pearl, even if it is a drawing, it also needs a large amount of faith power.

Although he can summon a very complex Gatling, and the power of faith is not too much, that is because the status of Gatling and machine tools cannot be compared, once the machine tool is manufactured, it is equivalent to a revolution, with epoch-making significance, as long as there is a machine tool, Gatling is nothing at all, that is, it is not impossible to create something more powerful and complex than Gatling.

Although it is not yet possible to manufacture machine tools, some simple human machinery can still be manufactured, such as human drill bits, and after improvement, the drill bit can be driven by the power of nature.

After Chu Nan's indirect allocation, the steam engine is about to be manufactured, not only that, if there is a suitable metal, Chu Nan also wants them to make a diesel engine or a gasoline engine, of course, the simplest kind, such as a car engine, with his current realm, it is impossible to manufacture it at all.

"How's the steam engine going?" Chu Nan asked casually.

Tie Niu Han laughed: "It's almost successful, since the leader you gave us guidance, we have been trying, but there is no qualified metal, even if it is manufactured, the life is very short, and it can only be used for a short time, and now I directly use the alloys I made, and I have the ability to shape them, so, after dozens of experiments, it is almost finalized, but it is a little big, leader, please follow me." Tie Niu asked the others to continue working here, and he took Chu Nan to another building in addition to the research institute.

Before entering the building, I heard a dull loud noise coming from inside, the closer the distance, the louder the noise, especially the sound of releasing steam, the hissing sound was particularly harsh, and people couldn't help but want to escape.

As soon as I entered the huge factory, I saw a bunch of people in the distance, a particularly large iron lump in the middle, a chimney on it, constantly spewing out a white gas, making a hissing sound, and some people kept filling it with coal, and everyone's face showed an excited look.
