This method is a cycad with the surname of the ironsmith, this method is called the two-phase method, it is a rapid melting method, which requires the addition of a special powder, and there is also a smelting method that matches this.

This blacksmith is a very thoughtful person, he didn't plan to use this ancestral secret technique here, but the bonus of 3,000 yuan, especially some of the systems of this blacksmith workshop, is very in line with his ideas, so he simply took it out and made a simple attempt.

Under the premise of the whole blacksmith process, the two-phase method is a special combination, the efficiency is improved a lot, a lot of time is saved, and there are different effects in iron smelting, steelmaking, and building.

The best is in iron smelting, which is 27% more efficient than before, and at the same time saves a lot of fuel and time, while steelmaking is slightly worse, about 18%, but in smelting, it is not much improved, about 7%.

In this way, the overall efficiency is estimated to be about 11%, which is a lot higher than the previous 7% of the labor force, and it is also very beneficial for the entire smelting workshop.

This incident once again alarmed Zhao Xin, he didn't expect that after the angle of labor for him was also made up, there would be such an improvement.

I also studied the powder of Surin, took it out, and what else was kept secret, this powder is a natural rock grinding, and it is a natural powder.

Looking at the card system, Zhao Xin knew what the reason was, this is a catalyst, to be precise, a catalyst for desulfurization and dephosphorization.

The grade of iron ore in China is not high, and the vast majority of iron ore contains phosphorus and sulfur, these two materials, which are very harmful to steel and will affect the grade of steel, so in the process of ironmaking, the constant beating and some unique actions are all in order to get rid of him, which also causes the ironmaking time to be quite long.

After Zhao Xin changed the ironmaking process, the temperature and sealing degree have been reached, but there is no major improvement in the process, the reason is that after the improvement, the effect is not good.

But with this catalyst, it is different, of course Zhao Xin knows that in later generations, there will be catalysts in ironmaking and steelmaking.

Catalyst is a special compound, in the chemical reaction, it itself will not change, after addition, it will promote the rapid reaction, or reduce the reaction conditions, in the industry is quite widely used.

Zhao Xin is just a historian, and it is quite good to be able to know some knowledge of ironmaking through the consulting era of later generations, and it is really difficult for him to know the catalyst.

However, the emergence of this natural catalyst fills the gap, which can not only be used in this blacksmith workshop, but also can be used in large-scale blast furnace ironmaking in the future, which greatly saves time.

There are so many compounds in nature, so many natural minerals, you can't test them one by one, so down, not to mention whether it can be achieved in time, let's just say that the cost is already very terrible.

Surin is only in the initial stage of using catalysts, and he even only adds them according to the ancestral story, although the improvement is not small, but there are still some problems with the use of this.

In the introduction of the card system, and adding his own understanding of ironmaking, Zhao Xin adjusted the entire step, and sure enough, Su Lin did not develop the full effect of this catalyst, and the final increase in iron smelting was not 25%, but two-thirds, that is, the efficiency was increased by more than three times.

In the same way, this catalyst is the largest for the improvement of steel, the increase of steel is 4 percent, and the finished product barely reaches 1 percent.

It seems that the total increase should be about 15%, but Zhao Xin doesn't see it that way, any aspect of the improvement, converted to the whole, will not be so low, this needs to be adjusted, it needs to be coordinated and regulated, this point, the people of the Northern Song Dynasty do not know, but he is clear.

Iron and steel finished products, which are the three pillars of the ironmaking workshop, their output has changed, and the adjustment is necessary, Zhao Xin spent 4 days to re-produce a process.

This is still thanks to the previous experience, because the previous adjustment, according to the output, according to the cooperation between each other, there has been a preliminary law, although this time the change is relatively large, but it is still within the scope of coordination.

After this coordination, it is easy to integrate the results of coordination into production, and the overall efficiency has increased by 50%, which includes iron, steel and finished products, thinking that the efficiency of iron and steel has been improved, and the personnel responsible for which link have been reduced.

Gathering sand into a tower, that's what it means, the final effect is very good, and the production efficiency of the entire workshop has once again been greatly improved.

Because of the huge effect of this effect, especially the catalyst, for the future iron and steel industry has a huge effect, this catalyst, may not be as good as the later generations, specialized production of catalysts, but in terms of efficiency and performance, it is already quite good, at least, with the conditions of the Northern Song Dynasty, the initial can be used.

In this case, in the end, Zhao Xin raised the reward to 5,000 yuan.

In fact, the emergence of this catalyst is very terrible for the reduction of costs, and it is conservatively estimated that the cost of iron smelting will double again, reaching about 17 Wen per catty of iron, which is about 30 Wen per catty of iron, which is a lot lower, and steel and finished products will also decline, and the magnitude is not small.

In a short period of less than a month, because of the reward, the standard of the reward has been raised twice, and the highest standard has risen to 5,000, which makes everyone crazy.

In fact, there really is, China's iron-making began to appear in the Spring and Autumn Period and the Warring States Period, and it has been more than 1,000 years since the Northern Song Dynasty.

What is now exposed is only the tip of the iceberg, among these secret recipes, there are a total of 12 valuable catalysts, which can be used in the refining of a variety of steels, and even in the refining of steel in the future, which not only saves a lot of time, but also improves efficiency.

Although none of them are more effective than Surin, these catalysts have also given bonuses ranging from 2,000 to 4,000 yuan, and some other minor adjustments are also continuing, and the blacksmith workshop has begun to move forward frantically, and the efficiency has improved much compared to the previous trial run.

These blacksmiths are first-hand witnesses, they have seen the changes through adjustments, one by one, the secret recipes, and even the people who took out the secret recipes, and they only then understand that the secret recipe is used in this way, and there is this kind of operation.

The improvement of efficiency has not only caused a large-scale increase in output, on average every day, each group of blacksmiths, the iron-making number is 1500 catties, that is to say, with 2000 groups as the number, the daily number has reached 3 million catties, that is, 1500 tons, not to know, a shock, this seems to be just an ordinary combination of blacksmith workshops, may have an annual output of up to 500,000 tons of iron.

This is almost comparable to a large steel plant, of course, only iron, the output of steel is not enough, on the one hand, the output of steel does not need so much, on the other hand, the efficiency of producing steel, not as much as imagined, as for the finished product, it is even slower.

Under the division of labor of different blacksmiths, only about a quarter is used to produce iron, one-third is used to produce steel, and the rest is produced by various finished products, so that it has reached a relatively normal level.

In this way, the daily production of iron is about 375 tons, which is also a staggering figure, and the rest is converted into steel, and part is converted into various finished products.

After a month's adjustments and improvements, gradual running-in, and the arrival of these blacksmiths one after another, the total number of blacksmiths in the Daimyo Mansion reached more than 3,700 people, of which more than 1,000 were promoted from the senior apprentices.

For industrial production, simplification and flattening are a prominent aspect, why it is so difficult for blacksmiths to become, because blacksmiths must be familiar with all the skills of ironmaking, from smelting, to steelmaking, to molding.

In the Northern Song Dynasty, a qualified blacksmith must be able to support all the work of a blacksmith shop.

But for the steelmaking workshop, there is no need for this at all, there is a process for each step, most of the processes are relatively simple, as long as there is a certain knowledge of blacksmithing, which is exactly what is needed here, you can become a master craftsman, which is much better than ordinary blacksmiths.

Although some senior craftsmen have a lot of complaints about this practice, but for the parties, this is a good thing, they are the identity of helpers, but they can get the work of masters, of course, they are enthusiastic.

Some simple assessments, to put it bluntly, are to come up to practice, in the whole workshop, that is, more than ten or twenty products, as long as you can skillfully lead the personnel, refine these products, or complete the operation of ironmaking and steelmaking, you can become a master, once you are independent, you can enjoy the salary of a master.

This kind of reward and adjustment made the entire blacksmith workshop in full swing, and the daily output began to climb to a new high, and the power generated by industrialization was revealed, but for Wang Song, not only was he not happy, but he was sad.

The reason is very simple, this blacksmith workshop currently employs more than 23,000 people, including less than 4,000 blacksmiths, as well as a large number of helpers and laborers, according to the average monthly salary of 15 yuan, a month's monthly salary, is 300,000 yuan.

This is still secondary, the key is iron ore and various raw materials, although their proportion is not high, but during the month, it is almost 600,000, that is to say, the two add up to more than one million, if you do not speed up sales, I am afraid, the workshop will not be able to support.
