Nie Mao walked out of the factory, looked at the red sun hanging in the western sky, and breathed a sigh of relief. He enjoys this life, everything is in order, whether it is work or life, everything is in order. You don't need to think too much about it, you just need to do your job with peace of mind.

He finally came up with a way to process steel pipes, not to punch holes in the tool holder, but to open several evenly distributed grooves on the outside, and install water pipes inside to cool down the drill bit. The drill bit for drilling is very thick, and the front cutting edge is also short. Only in this way can the stiffness of the shank be guaranteed. The speed of drilling is not fast, and the time it takes to drill a hole is often measured in days.

It is not easy to groove on the tool holder, to ensure uniformity, balance of the tool holder, and the precision requirements of processing are very high. However, in the end, it is processed externally, and the milling method can be used, and there is no problem of heat dissipation.

Looking at the sun in the west, Nie Mao stretched his waist and walked outside the factory. When he was about to walk to the door, he saw Wood in front of him, and couldn't help but exclaim: "Brother Wu, if you have to be free, how about going out for a glass of wine?" ”

Wood turned to see that it was Nie Mao, and said, "Okay, okay, it's okay, let's go have a drink." ”

Nie Mao listened, walked a few steps quickly, and walked out of the factory side by side with Wood.

Walking on the road, Wood said to Nie Mao: "My brother is full of spring breeze, I don't know what happy events there are, I want to drink?" ”

Nie Mao said: "Nothing. Recently, I was told to do something, and I didn't know how to do it for many days, but today I finally came up with a way, and it was easy. Those of us who do our best every day, and when we get something, we are naturally proud. ”

Wood laughed, "That's true. Today I also solved a problem and was about to share it with others. ”

Wood was the first to dig coal, and because he had learned well, he was recruited to the iron prison to coke. These technicians often study together and get acquainted with Nie Mao. The two are about the same age, and they are both alone, and they have no relatives and no reason in the iron prison, so they get closer.

After walking for a while, Nie Mao couldn't help but ask, "Brother doesn't know what problem to solve?" It's not easy for you to coke there, and you burn it every day. ”

Wood smiled and took out a square thing from his arms, glanced at Nie Mao like a treasure, and said, "This is it." ”

Nie Mao saw that this square thing was made of copper, shining with golden light, and he had never seen it before, so he couldn't help asking, "Brother, what is this thing for?" The palm of the hand is a large piece of copper, but it is not cheap. ”

Wood smiled, opened a lid, and placed it in front of Nie Mao. Fingers hooked on a nearby mechanism, and slammed hard, only to hear a series of crunch sounds and a burst of sparks. The edge of the fire was like a chain of lightning, and it lit a wick in front of it, and the fire ignited.

Nie Mao was dumbfounded, watched the flames jump, and asked, "Brother, what is this?" It's amazing! You don't need a fire sickle or flint to make a fire! Isn't this kind of thing a treasure! ”

Wood triumphantly snapped the lid on it, and the fire was extinguished. Reopened the lid and pulled the mechanism again, and the wick was lit again in the midst of the sparks. After a while, Wood said, "It's called a running fire, and the name was given by the Judge." It looks magical, but in fact, it still has to use flint. There's a steel drum here, do you see? I'm pulling the mechanism here, and the steel wheel hits the flint and comes out to spark. The most important thing is the wick, which is connected to a cotton ball below, soaked in the tempered oil, so that it can be lit at once. ”

Nie Mao looked at the magic, and asked for the tap fire, and kept beating and extinguishing, extinguishing and fighting.

That's what lighters are. When coking came out, a lot of by-products came out, and Du Zhongxiao arranged people to constantly use various methods to fractionate, step by step more and more refined. From the initial use of air ducts for natural cooling, to the later use of various melts to control the temperature, divided into sections. A few days ago, in addition to coal gas, it was able to fractionate many kinds of oil.

Du Zhongxiao didn't know which of the various oils distillate was gasoline, kerosene, and maybe even diesel. Anyway, there is no other use at this time, and if it is lighter and flammable, it will be used as lamp oil. The lightest one was named hot oil, because it was extremely flammable, so he tried to get his man-made lighters out.

The flint of this era is flint, which cannot be compared with the alloy flint of later generations, and must be vigorous. Pulling the steel wheel directly with your hand, not to mention that it is easy to get tired with your fingers, for people who are not diligent in their four bodies, their skin is delicate, and they can't stand that sin. People with rough fingers can't afford this thing. So he made a mechanism and pulled the trigger below to drive the drum to rotate. It took a few days to get out of the woods.

In fact, lighters are easier to make than matches, especially safety matches, which still have high requirements for chemistry. Lighters are much simpler, but they have fuel requirements, and as long as there is flammable and non-volatile liquid fuel, they are easy to make. However, comparatively speaking, the manufacturing cost and use cost of lighters are much higher than that of matches.

The lighters that are now made are obvious luxuries, and their practical value is not too high. Du Zhongxiao just did it on a whim to try to benefit the products of coking coal fractionation and expand the product categories of Tiejian.

The steel industry will drive a large number of downstream industries, but it will not happen overnight. Du Zhongxiao's tenure is limited, and of course he does his best to extend the product line. Otherwise, not only is his political performance limited, but the iron supervisor is also prone to depression because the production capacity is greater than the market demand.

These small things, unlike the heavy industries of machine tools, are easy to be imitated by the people. The existence of a large number of private workshops and factories that rely on the iron supervisor is the guarantee for the vigorous development of the iron supervisor. Their ability to expand the market is much better than that of the government-run iron supervisors.

In the end, the driving force of industrial development depends on the market and the ability to make money. Relying solely on the military industry, the use is too single, and it is difficult to form a scale. Without a long industrial chain, no matter how large the steel production capacity is, it will eventually shrink.

After playing with Wood's tap fire for a while, Nie Mao said: "This is a good thing, there is such a thing at home, and it is not difficult to make a fire." However, this thing seems to be worth a lot of money, if you sell it outside, I don't know how much it will cost? ”

Wood said, "How do I know this?" However, it is estimated that it will always take one or twenty times. ”

Nie Mao was taken aback: "Such a small object, just for the purpose of lighting, will cost one or twenty yuan, who is willing to buy it?" ”

Wood laughed: "Brother, you don't know, there are rich people in this world like carp crossing the river, I don't know how many!" We think that dozens of dollars are a lot of money, and in the eyes of rich people, it is not worth mentioning at all! Left and right can only take fire, poor people use fire sickle and flint, and they can also make fire, how can they buy this thing. You see, the bread outside is all brass, which is not for the poor. ”

There is another thing that Wood did not say, that the oil used in it is also very valuable, and that the poor can afford it, and they cannot afford it. If these small things want to become daily necessities for the people, the entire industrial system must be developed. With the current situation, most of the products produced by the iron prison are luxury goods. Not to mention that the structure is so complex, it is a mass-produced enamel product, a basin, for ordinary people are large items at home.

Important industries have laid the foundation, but without the development of light industry, cultivating a market is a castle in the air after all.
