Chapter 303

Nowadays, there are three people in charge of iron smelting and steelmaking, who master the three parts of steelmaking steps respectively. This is Wang Kang's intention to prevent the leakage of steel stir frying method.

spoke of an old blacksmith who had been invited by Wang Dingchang for heavy money. He was also experienced and old fellow, named Qi Tieshan.

Listening to what Qi Tieshan said, Wang Kang asked suspiciously, "what's wrong?"

Qi Tieshan said with difficulty: "a batch of steel has been wasted..."

"It's normal," Wang Kang did not blame them. After all, it's artificial refining, not machines, and the refining process is not so precise.

"That It's a large number. Several heats have been wasted. "

"How many heats?" Hearing this, Wang Kang frowned slightly.

"It's like this." Qi Tieshan explained busily: "in steelmaking, we refine according to the method you told us, but in secondary smelting, we need to add iron powder, limestone and other ingredients."

"In the proportion, this amount is always not accurate, so it leads to..."

Hearing this, Wang Kang has understood that the main steps of stir frying method are secondary smelting, adding iron powder, continuously stirring, using oxygen in the air to remove part of the carbon in pig iron, so as to reduce the carbon content in pig iron.

One of the most important is the amount of iron powder added, adding more, but it is counterproductive, not only does not reduce the carbon content in pig iron, putting the cart before the horse.

"But this should not be ah, you have refined so much, occasionally this kind of problem, understandable, but not so many times."

Wang Kang thought and frowned.

"We are all based on experience, have a rough amount, but can not be accurate."

Another person interrupted: "in fact, there is no suitable weighing tool..."

Qi Tieshan echoed: "yes, we can calculate the ratio, but it's not accurate. Sometimes we need more, sometimes we need less This is... "

Wang Kang understood that the weight of this era is not unified, and the smallest unit is only two.

And sometimes it's stone (Dan sound), useful for fighting, useful for rising

That's all. In the actual weighing, the error is still very large, and the values taken from different places are also different.

Especially in the more accurate weighing, it is more difficult to determine, and they are using a different system.

Some are Quaternary, some are hexadecimal

In fact, Wang Kang has been aware of this problem for a long time. It's not only in weight, but also in meter length.

This leads to many problems in construction due to measurement.

Nie Zhongxing has also reacted before.

Wang Kang thought, had an idea in the heart.

"It's just this question. Is there anything else?" Wang Kang asked.

"That's basically the problem, nothing else." Qi Tieshan said.

"If it's just this problem, it's easy to solve!" Wang Kang said directly.

"What have you come up with, Master Kang?"

Other people also have doubts, but they know how powerful the young master is and dare not look down upon him.

Wang Kang's eyes glided past several people and said in a deep voice: "unified weights and measures!"

"Unified weights and measures?"

"Yes

Wang Kang nodded, then explained: "you have this problem, because the weighing is not accurate, there is no specific value, there is no unified unit."

"Then we'll unify the units, just take advantage of this opportunity to unify the length, weight, temperature, etc., so that there won't be such a problem again!"

"But?"

Qi Tieshan said: "although the units of measurement are various, they have been passed on all the time. If you change them, they are..."

"Your mind is still too closed!"

On the contrary, Wang Kang thinks that this matter is urgent. Now all kinds of construction have begun, and many new things are produced.

As Wang Kang has seen, firing bricks are the same in the same batch, but there are differences in the next batch. There are also steel products with the same specifications in the same mold, but different in the next mold.

In essence, there is no accurate length measurement.

When there are standards for measuring the length, volume, and weight of objects, the specifications will be unified in actual production, and the impact on the fiefdom is also of great significance.

Thinking of Wang Kang, he said directly, "this matter is settled. I can't change the surrounding areas, but in Xinfeng County, on my fiefdom, weights and measures must be unified."

"You'll see the benefits later."

"All right then!"

Several people looked at each other and nodded. They all knew that no one could change what the young master had decided

Wang Kang's efficiency was also very high. The next day, he went to the construction site and called all the responsible persons together to announce the decision.

Of course, there are doubts, but there is no objection.

The first thing Wang Kang is prepared to determine is weight, which is weight. Of course, he will not use the unit of gram or kilogram used in previous generations.For the ancient people, this kind of unit is too awkward and difficult to understand.

Therefore, he can only follow the original two systems.

But how can this value be determined? Wang Kang thought of a way Make sure with eggs.

In his memory, ten eggs is usually one jin.

He remembers clearly that in his previous life, there was a company specializing in local eggs. Sometimes when business was too busy, he would take ten eggs as a kilo.

Native eggs are relatively small, ten are a kilo, while those produced in breeding places are eight.

Wang Kang first ordered people to find a basket of eggs, from which he selected the most symmetrical ten for measurement, one or two for each, and ten for one jin.

Then he ordered people to use the leverage principle to make a balance scale, with an egg as the standard of one or two, to get the money, the unit.

With the measurement, it's easy. Wang Kang doesn't use hexadecimal system, but directly uses decimal system.

Ten coins is one or two, twelve is one jin, ten jin is one Jun, ten Jun is one stone

It is simpler and more accurate than the previous measurement.

In this way, the unified standard weight came out, and then he ordered the blacksmith to make accurate weights.

One or two, two, five, one jin, two Jin, five Jin

After making it, Qi Tieshan looked at the new weight and whispered: "one two is three, two two is four, one five is six, five is seven, one five is eight, two five is nine, five five is ten..."

"Master Kang, what's this

After listening to Qi Tieshan's words, people suddenly wake up. In this way, they have one to ten.

And the calculation is very convenient, very easy to get the results.

"The benefits of unification, you will naturally find in the future, Wang Kang said with a smile:" this weighing method is your future production and construction standards. "

"With this, when there are ingredients in the future, we will use this calculation, and there will never be any more problems."

"I see." everyone was in a good mood, especially the people from the iron making department such as Qi Tieshan, who understood the meaning of this
