Zhao Xin took Wang Song, came to the blacksmith workshop, from half a month ago, Zhao Xin included Niu Dali, including more than 40 masters, to concentrate here, to jointly study new products, in the daily time, basically according to the peak of Niu Dali to pay wages, if the research is completed, according to, in the process of research, the proportion occupied, give bonuses, the total bonus is as high as 10,000 yuan.

This is a very terrible reward, but at that time, Wang Song was more busy with the arrangement of orders and personnel, and did not care much.

It seems that there are some new products, Wang Song groaned, what kind of product is it?

Soon, through a series of blacksmith tables, the various tools in it, a little different from the outside, two huge, power-looking iron rollers, were squeezing the red-hot iron sheet, and soon, a flat, white iron piece appeared in front of everyone.

"What is this?" Wang Song asked puzzled, this piece of iron is very delicate, really as thin as a piece of paper, of course this is an exaggeration, but in a sense, he is much thinner than all the pieces of iron he has seen.

"That's the new product I'm going to show, White Iron." Zhao Xin said with a smile, the white iron sheet of later generations, in fact, is still steel, it is a more malleable steel, and the alloy composed of zinc is not easy to rust, and the thinnest thickness is probably less than half a millimeter, and it cannot be said that it is only as thick as a piece of paper, but it is also seven or eight sheets superimposed together.

The real white iron sheet, there is no need to think about it, the very demanding, even galvanizing process, is not something that the Northern Song Dynasty can explore in a short time, but according to this selection of iron with good ductility, and finally cast an iron sheet similar to white iron sheet, it is still possible.

This is the result of the final research of more than 40 masters, thin iron sheet.

The purpose of this research, of course, was to make everyday iron tools, and the research has now been largely completed.

When the iron sheet is finished, it will be sent to another room, where they are not blacksmiths, they are more like tailors, they will cut different parts on the iron sheet, according to the prescribed pattern, and use willow joints and buckles and other methods to combine and shape.

Soon, under Wang Song's nose, a kettle that was commonly used in the Northern Song Dynasty was completed.

Seeing the completion of this thing with his own eyes, Wang Song was stunned for a moment, when he saw the iron sheet, he didn't expect this to be a kettle, compared with the previous kettle of the Northern Song Dynasty, his face showed a stunned expression, and said weirdly: "Isn't this cutting corners?" ”

In the Northern Song Dynasty, the kettle is also a common thing, mostly forged, because the thickness of the iron plate is uneven, the kettle is often very heavy, a kettle, there may be three or four catties, willing to give up some materials, some large kettles even have ten catties, that is really difficult to use.

In this way, according to the price of iron in the Northern Song Dynasty, the general kettle is about 500 Wen or more, even if it is the current price of the blacksmith's workshop, the average 40 Wen per catty, the cost of the kettle is more than 160 Wen, plus some necessary profits, the price in the store, it is likely to be close to 180 Wen to 200 Wen.

But if according to the current experiment, using a thinner iron sheet, his weight will be very light, in front of Wang Song in his hand, this daily kettle, his weight is difficult to even one catty, which is equivalent to saving three-quarters.

Cutting corners is often to use less materials and do more things, but that kind of cutting corners, more is a little bit, for example, 5 catties, deducting one percent, half a catty is already terrible, reducing seven or eight percent, what does it mean, can this thing be used?

"Try it and you'll find out!" Zhao Xin looked at Wang Song's appearance and said nonchalantly.

Soon, a stove was brought over, and in the Northern Song Dynasty, not every family was a large ground pot, as long as a part of it was closed, it could be made into a simple portable stove that was simply used to boil water.

It looks like a light kettle, and it is also very unreliable, and it is placed on the fire, in Wang Song's opinion, such a thin iron sheet will definitely be burned through by the flames.

But to his surprise, the kettle was fine, and when the flame reached the bottom, it did not burn through the kettle, but began to heat the boiling water.

In fact, no matter how thin the iron is, as long as the temperature does not rise to a certain extent, for example, seven or eight hundred degrees, there will be no problem, and there will even be thin aluminum kettles in later generations, which is really not high, if you don't add water, dry boiling, it is easy to burn through.

The kettle does not need to be so strong, the kind of aluminum kettle and thin iron kettle of later generations are just a very thin layer, simple burning, it is easy to burn through, but if you put in water, there is no problem.

Water is a very special thing, the temperature is between 0 and 100 degrees, 0 degrees will freeze into ice, and 100 degrees will evaporate.

That is to say, as long as there is water in the kettle, the temperature cannot rise to more than 100 degrees, even in some areas, without timely heat dissipation, the temperature will rise very much, and it will not be very high.

100 degrees, not to mention iron, even ordinary paper is unlikely to be burned. In this range, even other things with a lower melting point are not easy to burn through, and there are even paper barbecues.

This point is the basic principle of physics, in later generations that it was common sense, in the Northern Song Dynasty, it was people did not pay attention to it, it will appear, as strong and durable as possible, but things are used too much, and the cost will go up.

With the help of the new forging technology, to put it bluntly, at high temperature, the iron sheet enters the two layers of rollers, and with the help of mechanical power, the thin iron sheet is processed, which is not only outstanding in performance, but also very light and thin.

In this way, the weight of a small and lightweight iron kettle will be greatly reduced to an unbelievable level, only a little more than a catty, only about a quarter of the previous one.

The kettle that can also boil water, not to mention the cost of raw materials, under the premise that the raw materials are the same, one is heavy and one is light, and the cost will come down.

How long does it take to boil a pot of water, on the premise that the fuel is sufficient, it is about a few minutes, and it is completed.

Looking at the crazy bubbles, it was clear that the water was boiling, but the pot was fine.

Wang Song was a little out of shape, he picked up the kettle, put the water into other containers, didn't care about the heat, turned over and over, although when boiling water, the bottom of the kettle, there were some black traces, but the whole, quite complete, without any damage

"This, why is this happening!"

Zhao Xin doesn't explain, if he does, is he going to explain the three states of the object to him, the solid, liquid and gaseous, this is the whole physics, it is really not easy to explain.

simply didn't explain mysteriously, Wang Song really understood that this should be an immortal method, which saved a lot of explanations.

However, after Wang Song stopped asking, he seemed to think of something and wanted to say it, but he stopped talking.

"It's okay, Wang Song, if you have anything to say, just talk about it!"

"Is this thing durable?"

In the simple thought, the amount must be enough, it will be durable, and this kettle is no longer a matter of light weight, but a somewhat fatal problem of lightness.

It directly reduced the weight by seventy or eighty percent, as thin as the skin of a cicada's wings, even if it was a woman who had no power to restrain the chicken, it seemed that she could destroy it.

That's right, this is the iron sheet, even if the white iron sheet of later generations, an adult, with a little force, can be destroyed, although it will not be pinched, but it can be deformed.

But this is not a farming tool for fighting, this is just a kettle, the function of the kettle is to boil water, and it is not used for work, as long as it does not burn out, a kettle can be used for a long time.

This point has been verified by later generations, but seeing that Wang Song still doesn't believe it, remembering another thing, he said to Niu Dali: "I remember that here in the research institute, there is a special kettle, which is the first time it has been made, is it still there?" ”

Niu vigorously paused for a moment, and then said, "Yes!" ”

Before joining the blacksmith workshop, Niu Dali has always been confident in his own skills, and after joining the blacksmith workshop, he received a lot of monetary rewards, and he thermometered, which directly promoted the change of the blacksmith workshop.

In his opinion, the blacksmith's workshop is nothing more than that, and the greatest magic is that the master gathers these craftsmen together and aggregates everyone's knowledge.

At the beginning, he was not very happy to be recruited by Zhao Xin to study new things, but he didn't have to work hard, and he could get a high reward, and it was in this way that he reluctantly came over.

But after he came, he found that he was a frog at the bottom of the well, and he seemed to have no secrets in the blacksmith's workshop, and the theories contained in it were far from what he could imagine, that is, the occasional on-demand of the old master made him understand, but the bigger surprise was this new smelting method.

It seems a bit strange to make a thin iron sheet with utensils and make all kinds of daily necessities out of the iron sheet, but the actual effect is very amazing, and the weight reduction will make these daily necessities cheap to an unbelievable situation.

Even if Niu Dali was an official blacksmith before, many times, it was an official order such as building weapons, rather than civilian items, but the cost of providing forbidden army equipment on a large scale also needs to be considered.

In the entire Northern Song Dynasty, any change in weapons and equipment would be a big deal, because when the number rises to the level of hundreds of thousands, or even millions, the reduction of one or two liters is enough to move the upper echelons, and sometimes, it will even alarm the privy envoys.

Like the blacksmith's workshop, it not only greatly reduces the cost of iron smelting, but also creates this kind of daily necessities that can reduce the consumption of eighty percent of iron, how competitive it will be, this point, he knows very well, because of this, his attitude began to change, and he really lowered his posture and maintained respect for Zhao Xin.
