The charcoal fire was concentrated next to the furnace and ignited, the scorching temperature made the surrounding temperature rise significantly, the whole reactor was closed, there was no internal sensor and internal monitoring, Zhao Xin could not, and it was impossible to know what was going on inside.

To put it bluntly, this is a very hasty attempt with no quality and quality control, and if there is no card system and the identity of the traverser, such an experiment is basically a joke, and it is impossible to get any results.

The card system gave Zhao Xin a chance, in the complex mixture, it was possible to determine whether it was completed, and the raw materials of the entire Lubrande method were also found by Zhao Xin, and the steps were correct, everything was done to the best, the raw materials were sealed in this iron box, and after the flame burned, it was a long wait.

Industrial chemical reactions, rarely instantaneous, instantaneous rapid reactions, often in the laboratory, for example, magnesium combustion, these are instantaneous oxidation processes.

However, most of the chemical reactions are relatively slow, the reason is very simple, deflagration and instantaneous reaction, his result is either explosion or flame, the controllability is too poor, the danger is also high, really to generate magnesium oxide, it is absolutely impossible to directly burn the magnesium bar to make, that is not production, that is arson.

When a magnesium bar burns, at most it is a bright light, slightly raising the surrounding temperature, but thousands or even tons of magnesium bars are ignited by the impetus of the flame, then it is not a reaction, it is arson.

Oxidation reactions, most of which are violent reactions, emit light and heat, and magnesium strips are the best among them, such reactions are very simple, but uncontrollable, and can easily cause irreversible consequences.

In general chemical production, time is the biggest cost, any saving of time, is a great progress in the process, the ironmaking of later generations, the initial upgrade is from the ordinary steelmaking furnace of a few tons, to 300 tons, 500 tons, or even 1000 tons.

However, such a simple increase in volume is quite limited for the improvement of overall efficiency, and even has a ceiling, when the 1000-ton steelmaking furnace appears, it is already the limit, and it will cost a lot to improve, and the effect is not good. Because of this, steelmaking began to move to other aspects, from a furnace in 3 hours to a furnace in 40 minutes, after decades of technological improvement, the efficiency has been greatly improved, and the time is still much longer than that of the laboratory.

At the beginning, the flame was not stable, a large amount of charcoal and furnace, so that the temperature rose sharply, soon exceeded 700 degrees, iron after 700 degrees, it will be red, heat, ordinary blacksmiths, often use this, under the premise that the temperature is not reached, for iron calcination, smelting, some high-quality steel, is so after tempering again and again, the final forming.

The blacksmith is more familiar with the flame, Zhao Xin is asking for a higher temperature, almost the same as the pottery burned, he has not burned the pottery, but he also knows what is higher than the red burning, and continues to strengthen the flame.

The temperature of about 1,000 degrees is dangerous for anyone, Sun Ji is very powerful, but he is still a mortal in the flesh, it is impossible for him to be immune to flames, and everyone else is the same, everyone is scattered, only Zhao Xin and the blacksmith stand closest.

"Almost!" The blacksmith said with some uncertainty.

"If you think it's about the same, then start settling down!" Zhao Xin said affirmatively.

Maintaining the temperature is a technical job, Zhao Xin did not interfere, and watched the blacksmith control the temperature, reducing the heating efficiency of the two furnaces, and controlling the temperature to a relatively balanced degree.

Seeing that the red bottom is no longer deepening, Zhao Xin breathed a sigh of relief, the biggest problem with this chemical reaction is in terms of heating, once the heating is completed, the next thing is to maintain this temperature and provide a good environment for the reflection.

The fundamental reason for choosing the Lubran method is the same, it is very simple, except for heating after mixing, there are no other special reaction conditions, and the temperature requirements are not particularly precise, as long as the temperature is roughly 900 degrees to 1000 degrees.

The temperature continued to rise, and those close to the furnace had already felt the heating, including the iron box itself, which had been heated to a crimson appearance, not only radiating a large amount of heat, but also the heat of its own light.

In order to ensure Zhao Xin's safety, Sun Ji took him to the outer circle, and he had already retreated to the range of the longbowmen.

Zhao Xin asked the longbowmen to come over, just to help with the things, now, the reaction has begun, as long as the temperature is controlled, not too high, not too low, and the smooth reaction can be carried out, the longbowmen will not be of much use.

At this time, the longbowmen who no one paid attention to were discussing what it was, they didn't know that Zhao Xin met the immortals, but they knew that Zhao Xin's status was very high, and they could guess anything, and even some people opened their brains, thinking that this was the magic of turning stones into gold, and in legends, turning stones into gold also had a strong sound and light effect.

Zhao Xin looked at the gossiping longbowmen and quietly instructed Sun Ji, and then Sun Ji and Xue Yu left with the longbowmen, because, according to Zhao Xin's estimate, the entire reaction process will last for most of the morning, or even longer, and there is no need for everyone to waste here.

The Lubland method takes a lot of time, the first production, the time consumes a little longer in the future, with the increase in the number of experiments, as well as the improvement of the chemical process, will gradually reduce the process, but that is later, the chemical industry and the steel industry, are capital, technology and personnel intensive, in the absence of a stable territory, without the premise of sufficient population base, these industrialization can not be completed.

The calcination process lasted for a long time, the reactor was made temporarily, there was no good conversion, and the charcoal consumed was more, fortunately, the total of more than 20 catties of materials, it took almost 2 hours, in which the blacksmith has been staring, and some adjustments have been made to the flame to ensure that the flame has been maintained at a temperature of relatively no more than 1000 degrees, and the temperature control is very good.

The impact of the high temperature is quite terrible, several times the iron below has been quite red, some signs of melting, he adjusted in time, reduced the output temperature, in the continuous calcination, there is also billowing black smoke on it, some of the carbon combustion is not sufficient, the generated carbon monoxide, are escaped through the air.

This is a specially designed chimney for extraction, and most of the carbon monoxide is extracted by the chimney, and the impact is almost non-existent.

Because of the high temperature, all those who were still present did not come to the front, even if they were in the front, they also used some masks, mostly after the cotton cloth was wet, because carbon monoxide was lighter than the air, and it was extracted upwards, and most of them rose to the sky, which would not affect them a lot, even if there were, masks could also help in time.

Without an accurate thermometer, no stirring and automatic control, Zhao Xin could only choose the simplest method, calcination, and non-stop calcination until the end of the final reaction.

Zhao Xin didn't even know how long it would take to react, so he kept burning, and it took 2 hours, that is, a morning, to pass the time, and it was almost over, so he ordered the fire to be extinguished.

Hearing that the reaction was over, the fire had been extinguished, Sun Ji and the others came over again, wanting to see what kind of thing it was, but what they heard was another result, and they still had to wait.

That's right, the reaction is complete, but the cooling still needs to wait, from the high temperature of thousands of degrees, down, without the premise of building a cooling tower, only the method of natural cooling, adding water or other methods, it is impossible to use.

Soda ash is easily soluble in water, once rinsed with water, then the final product, will be washed away by water, when the time comes, after spending a lot of effort, nothing can be obtained, this is not his original intention.

After lunch, Zhao Xin didn't go back to the scene, just asked the person who was staring to wait until the temperature cooled down and told him that it was okay.

Conventional reaction devices need to build cooling towers, with the help of circulating water, cooling, so that the circulating water can also recover a large amount of heat for bathing, or other hot water supply, which is also the reason why some large chemical plants and steel plants have this negative benefit, these are waste utilization.
