The composition of iron ore is verified, and dozens of fairy world standards have been issued, and a bunch of ore is obtained, and the number of samples and locations must be determined from the number of waiting for the smelted ore, Li Ruixiu felt that his head was big when he looked at it, and Fuer felt a sense of reverence rising from his heart, in the words of the fairy world, it should be "scientific", every step, every variable has endless scientificity, he made a converter before, and the craftsmen made steelmaking based on experience, but it was improved by scientific methods, corresponding to different types of converters, The size of the materials in the furnace is different, accurate to a range in millimeters, Li Ruixiu sighed with emotion at the same time, but also deeply felt that he was small. Pen ~ fun ~ pavilion www.biquge.info

I thought that I could fully replicate the testing process of the fairy world, but now it seems that it is a bit of a fool's dream, so I can only make the main test first to determine the iron content.

Li Ruixiu took out a pen and paper and carefully copied the ore sampling method of the fairy world, first using the physical properties of the ore to roughly determine which type of ore it is, and then how to sample and what the sample size is.

The current craftsman does not have an accurate meter ruler, and he also draws the length and scale of the ruler on the description, and he does not plan to hide this part, but is ready to sell it all to King An, and he can also accept a lot of money to teach those craftsmen in person.

Get the iron ore fairy world can detect various components, but Li Ruixiu can only start by detecting the iron content at this time, he can't use the ICP analysis of the ancestors, he can only choose the most traditional titration analysis method, this method is not very accurate, but that is relative to the requirements of the immortals, Li Ruixiu does not feel inaccurate, it is simply shocking.

First of all, there has to be a bunch of chemical experiment equipment, what beakers, Erlenmeyer flasks, Li Ruixiu drew the appearance and handed it to Liu Fu, and asked him to produce it, or blow glass with molds, those craftsmen have already done it once, although in the New Year, but enough power and money can still make people open the furnace. He knew that the inner wall of the experimental equipment he got would not be smooth, and the capacity would have to be redetermined by himself, and what milliliters, grams and other measuring tools could only be estimated according to the small stories of the fairy world.

The first reagent is hydrochloric acid, Li Ruixiu looked at the preparation plan of chlorine, even if it is large-scale production, the fairy world uses electrolysis, Li Ruixiu couldn't help but be happy, he has a generator, direct current, and completely qualified to prepare hydrochloric acid, first electrolyze, pass chlorine into distilled water to reflect, and then heat to decompose hypochlorous acid, Li Ruixiu almost cried with joy, the first reagent was so easy to obtain.

The imperial court controls the circulation of salt and iron, and Li Ruixiu now has to use salt and smelt iron, and it is thanks to the identity of this colt that he can buy these things in large quantities.

The animal power generator used at home has a commutator at home, and although the electricity emitted fluctuates, it becomes 0 at most, and there will be no potential reversal, which is enough for electrolysis. Things have to be done step by step, Li Ruixiu plans to put this matter down first and see what reagents are needed later.

Potassium dichromate is good to say, it can be made with chromite, arsenic chloride is not really no way, sodium tungstate needs tungsten ore, because he has been manufacturing filaments before, Li Ruixiu has also paid attention to tungsten ore on the market, but Li Ruixiu, the indicator behind him, has a headache, and he can't think of a way to get it.

He kept flipping through the fairy books, and tried to devise a not very precise scheme: use chlorine to reduce all the divalent iron and chlorine into trivalent iron, and then use calcium hydroxide and sodium hydroxide plus filtration to remove impurities, and finally weigh the mass of iron hydroxide to calculate the approximate content of iron.

Li Ruixiu wasted two days in order to think of this method, the first day was to completely deny the possibility of being able to manufacture sodium diphenylamine sulfonate indicator, and the second day thought hard about other schemes, this method is naturally inaccurate on the basis of the original inaccuracy, but the reagent is easy to obtain, chlorine is already available, the electrolytic salt is left is sodium hydroxide, calcium oxide can be bought on the street, and the steps for accurate measurement have become fewer.

Li Ruixiu estimated that the error might reach 3-4 percentage points, and he had to pray that there were no soluble impurities in the original iron ore that were not mentioned in the book.

He carefully designed each step on paper, drew and sorted out the graphics, wrote the preparation plan of the reagent on several other experimental design books, and finally checked it again, instructed the little guy to buy raw materials, and began to sort out the abandoned design in one place, although the standard titration scheme of the fairy world could not be used, but Li Ruixiu consciously understood the manufacturing scheme of several reagents in this process, he thought about it, or sorted it out, and used the chemical symbol record of the fairy world, even if it was found and could not be deciphered.

After a few days, waiting for all the equipment to be sent, it was supposed to be all beakers and Erlenmeyer flasks, but this time the experimental protocol was changed, the volume was not needed, and the reagent could be passed through the excess every time, the only thing to pay attention to was weighing, so a small scale that could be accurately weighed still had to be had, the immortal used the balance, and he also drew the pattern of the balance for people to make, this fixed weight was simple, and the small scale that was originally in the world was combined with the density of the ice cube, and the scale was quickly divided.

There was news from the palace that because of the preparations for the war in the northwest, the celebration palace banquets on the fifth and fifteenth days of the Lunar New Year were canceled, which added a lot of time for Li Ruixiu to stay at home. He knocked down a piece of ore, carefully experimented, each step was cautious, still missed a lot of places, got some data wrong, after two days of experiments, finally got the dried ferric oxide, calculated the iron content in the ore.

According to the quality of the iron ore, 13 groups of experiments were carried out, which roughly determined the iron content of the whole ore, and then urged the craftsmen to use a new furnace to smelt the ore into pig iron.

Li Ruixiu, the workshop on the mountain, is not used at present, so he lent it to the Chinese army, and he didn't collect anything, and the Chinese army also took the initiative to give the Li family some more charcoal.

The craftsmen saw Li Ruixiu come to steelmaking, not only pointed out that they wanted to use a new furnace, but also carefully weighed the furnace together, that funny appearance made people want to laugh but a little stunned, this man-made steelmaking scheme they are puzzled, how many old craftsmen privately said that Li Ruixiu is extraordinary, can use the Dan furnace to train good steel, the steel must be subject to the alchemy of the immortal energy, and Li Ruixiu only cultivated the immortal for less than half a year to ignite the immortal qi, he may really be able to become an immortal one day.

Someone secretly sniffed the fairy gas made by it, and after smelling it, he was refreshed, and he found an opportunity to suck it ruthlessly, and after a while, his whole body was hot, and he looked excited, but he fainted after a while, and everyone said that he was an ordinary man and couldn't stand the fairy spirit.
