On the blacksmith's table, instead of the charcoal often used in the Northern Song Dynasty, coal was used, or treated coke.

Coal is a compound that plants have been buried in the ground for many years and eventually formed, because of different plants and different formation mechanisms, the combustion value is also different.

When the steam engine was first used, the coal used in the ship was often extremely heaty, so as to ensure the efficiency of the ship.

The mining conditions of the Northern Song Dynasty, and even the detection methods, could not determine the heat of the coal, but when the coal was coking, the heat could be greatly increased.

The use of coal is the biggest change in the reform of the blacksmiths in Miaojiazhuang, compared to charcoal, the price of coal is lower, especially the location where they are located, this is the Daimyo Mansion, the place where Henan and Shandong are at the junction of later generations, there are large coal fields.

In fact, in the entire Northern Song Dynasty, the use of coal hit a new high, and after simple coking, the heat of coking coal increased, and the efficiency began to improve, which was also the core competitiveness of the blacksmith workshop.

In fact, many things in this process are not adjusted much, but the final adjustment will be shown to the cost.

When I was in Miaojiazhuang, at the beginning, it was almost the same as ordinary ironmaking, and then it gradually decreased, and when I left, a set of standards had been formed, which not only had high efficiency, reduced waste, and reduced costs.

However, because there is no blast furnace for ironmaking, compared with large-scale ironmaking, the cost is not reduced much, the transportation is convenient, and all aspects of management keep up, as well as the use of coal, reduced costs, improved efficiency, and finally the price of a pound of iron, finally reached 37 Wen, which is at least nearly half of the previous general.

This is not the limit, in Zhao Xin's view, if the blast furnace ironmaking and steelmaking can be combined, the cost of iron will be reduced to one-tenth of the original, that is, the level of seven or eight Wen, which is the price that is most in line with the objective law.

It's just that that's later, and the most important thing for Zhao Xin now is to make money.

In fact, the price of 37 Wen is very competitive, and the price of pure iron is very competitive, with a price of about 70, less than 10 Wen a catty, it can basically crush everything.

It seems that it has been reduced from 80 to 70 Wen, which is not much, all iron products, but not one or two catties, an iron rod has a weight of ten catties, in this case, the cost of reducing 10 Wen, for the finished product, may be one or two hundred Wen, this price is very tempting.

Although it is said that Dinghai has a lot of problems, Zhao Xin still did not leave, he needs to smooth out this place first, industrial production, there are many things that can be adjusted, which is not the same as the previous adjustment of the blacksmith.

The original steamed bread and soap these things, there is nothing to improve for the time being, there is distortion, it is between subtleties, but industrial production, this is different, a little negligence, will cause a huge waste, and a little improvement, will make the yield and cost greatly reduced, in the Northern Song Dynasty this time and space, no one can replace him to make this adjustment.

Industrial production is a brand new thing, such as some coordination, so that everyone is invested in a thing, so that every link, under the premise of the same, it seems that everyone's workload is not much improved, but in the end, the overall efficiency is very high, in a series of environments, make some adjustments, which is counted in each unit, you can improve a lot.

It is estimated that it is impossible to cut it in half at once, as before, but it can be compressed by about ten wen at least, that is, the price of iron will be reduced to less than 30 wen.

About 10 wen, it looks inconspicuous, but if it is 400,000 catties a day, it can save 4,000 yuan a day.

Large-scale industrial products, let alone 10 texts, half a text is a terrible number, especially the degree to which the quantity can be broken.

Why did Zhao Xin choose iron, because before a certain amount can be reached, the demand for iron will not weaken much, and even with the reduction of prices, some new uses will be developed.

For example, in the Northern Song Dynasty, most of the uses of iron are kitchen knives, farm tools, some iron rods and other necessary iron products, and have not yet entered other fields.

However, when the price of iron decreases, there will be more areas that can be used, such as tableware, such as various daily necessities, and even some machine tools.

Iron is a material with strong plasticity and excellent performance, which can be widely used in various fields of life, but because of the high price, it has not been used in life on a large scale.

After a brief understanding of the situation of the workshop, Zhao Xin did not leave the Daimyo's Mansion, but stayed, he needed to see for himself, what else needs to be improved in this smelting process, this is a very important thing for them, he is related to the final cost, and the cost determines the profit.

If this workshop can go all out, it can produce 400,000 catties of iron per day, and every time his cost is reduced by 1 wen, it is 400 catties, and every 100,000 catties of production is increased, it is a terrible increase in income.

More than 200 stations have progressed to more than 600, and with the increase in personnel, some problems have begun to appear.

For example, the problem of cooperation that has never appeared in Miaojiazhuang before, has appeared, coal, raw materials, iron, steel, which is basically a few key points of smelting, and it is not easy to cooperate between them when small-scale production was carried out before, and it has appeared here.

Before, the blacksmith only came because of the monthly salary of 5 yuan, but now, knowing the standard of this commission, if you have 400 catties of iron a day, you can get 800 Wen, which is fast and consistent in one day, and I immediately invested great enthusiasm.

Some people work longer hours, some people increase the intensity of work, which results in basically, every blacksmith table, slightly exceeded.

This is a good thing, but when good things come together, it's not good, the raw materials can't keep up, iron, steel must have a certain proportion, and the refining process is slightly different, and compared to iron, the performance of steel is better, the commission is higher, and many people will smelt less iron and make more steel.

This is human nature, everyone wants to make more money, which is nothing, but under the imbalance of proportion, the raw materials are gone, and finally caused a complete shutdown for 1 hour.

This is only the first big problem encountered in large-scale smelting, and other small problems are also emerging.

Wang Song was overwhelmed by such a problem, only 600 units, there were so many problems, in the future, as Zhao Xin said, 1000 units, or even two or three shifts, how many problems should there be.

Wang Song even turned to Zhao Xin for help, but he didn't expect that after Zhao Xin listened to Wang Song's words, he laughed, he was a little too worried.

If it is industrial production, there will inevitably be problems, and there are many problems of all kinds, and what we are afraid of is not that there will be problems, but that there will be no problems.

It is impossible for Zhao Xin to be here for a long time, the Dinghai Navy, and the Xiang Army, these are all complicated, the Dinghai Navy is the foundation, and the blacksmith workshop of the Daimyo Mansion appeared to make money, and one cannot be ignored.

When he was in the Daimyo's Mansion, he couldn't finish the problem, and it would be a big trouble when Zhao Xin left.

He is going to take this opportunity to make a standard, just like the previous ironmaking, to sum up the most suitable standard, and everyone will follow this.

The problem of the ratio of raw materials, this is a small problem, just a problem of coordination, when arranging, a certain margin flows out, and under certain states of compulsory orders, a part of the iron must be made.

When there is a problem, solve the problem, and then sum up the experience, in Wang Song's stunned, the rules and regulations of the entire blacksmith workshop, with the speed that can be seen by the naked eye, rapid molding, from the beginning to the end, from the simple material ratio, to some cooperation, and even the time of work, there are detailed requirements.

In short, the regulations are very detailed, and everything is very detailed.

Change is not easy for anyone, and it is quite difficult to move people from disorderly work to orderly work, and it is easy to rebound.

However, there is no such thing in this workshop, it is not that no one has challenged the previous iron smelting regulations, and even that regulation is not rigidly arranged, but all challengers will be punished.

Or the labor intensity has increased, the work that may have been done in 8 hours in the past may not be able to be done well in 10 hours, and the output has also decreased, adding some scrap rates, not only does not make money, but also loses money.

It is this example, this rules and regulations, and the smooth implementation, everyone was surprised to find that just according to this rule, the whole workshop is no longer messy, some waste that should not appear, there is no appearance, everything is in order, what should appear will appear, and the efficiency has increased by more than 3 percent.

Large-scale production should be slower than small-batch production, because there are more people, and there is an impact on each other, but under Zhao Xin's adjustment, the influence between each other has been reduced to the lowest level, and it has produced a similar catalytic effect, for example, some semi-finished products can be directly sent to another smelting table, which is somewhat similar to an assembly line, but also somewhat different, so that the efficiency increases.

The output of a unit itself is about 400 catties, which has increased to about 570 catties, the efficiency is improved, the consumption is reduced, and the entire cost is further reduced.

Zhao Xin knows very well that to this extent, the rules and regulations are almost over, and the rest need to be gradually improved in the gradual production and exploration, although there is not much space.

He didn't plan to go deep into this smelting, it would inevitably be replaced by a steelmaking furnace in the future, and he would have to consider the direction of the product after the production volume stabilized. 10
