Da Qin: At the age of six, I beat Qin Shihuang at the beginning

Chapter 256 The Problem

"Okay, this matter is over here. Old Wei, you asked me to come over, what problem did you encounter?"

Although the things Wei Yu experienced just now were not many, they were somewhat complicated, and his mind is still in the process of recovering: "Ah...you wait for me to think about it... By the way, the rails we cast always have some places where the thickness is not consistent... ..."

Inconsistent thickness?Qin Mu frowned, this is a tricky question.

When the train runs on the rails, it is fixed together by the slots between the wheels and the rails, so that the train will not derail.However, the two sides are not closely connected after all, so this card slot will naturally leave a certain gap.

And in order to ensure stability, the gap should not be too big, nor too small!Generally speaking, according to the requirements of later generations, the error of rail production should be within five millimeters.This number itself is difficult to see with the naked eye.

And Wei Yu said that the inconsistency in thickness is obviously a situation that can be seen with the naked eye.If such an error is installed, the probability of accidents will increase greatly!If there are one or two occasionally, it's fine, just listen to him, this is obviously not a question of one or two!

"Take me over there!"

Qin Mu didn't say much. There are many reasons for production errors. Workers' operations, molds, cooling irregularities, and even proficiency will all lead to errors. Without on-site inspections, it is difficult for even Qin Mu to guess the reasons.

Wei Yu quickly brought Qin Mu to the place where the rails were stored.Qin Mu looked at the steel rails one by one. There were dozens of steel rails lying flat here. Qin Mu frowned and looked at them one by one. Errors are common!

Moreover, the most important thing is that the place where the error occurs is not fixed, but the most frequent are the two positions of the head of the rail and the upper middle.

"Since when did it become like this?"

Wei Yu thought for a while and said, "Yesterday! After I got the blueprints for the production of the rails, I started preparations. I selected a few blacksmiths with the best skills, and after screening, they came here to start production."

"Of course, in order to ensure the quality of the rails, I used the strictest inspection!" Wei Yu picked up a long wooden ruler from one side: "The wooden ruler is completely straight. Put the wooden ruler on the rails, Only when it fits perfectly, is it qualified! If there is a gap or a bulge in the middle, it means that there is an error!"

"All errors that exceed the size of an ant are considered unqualified! After half a day of correction, the error has basically disappeared! But, I don't know why, so many problems have appeared since yesterday! We have tried various methods , but still can’t get rid of it, so I have to ask you for help!”

Qin Mu nodded, probably understanding the situation.

"Most of the errors occurred in those two positions, so it is likely that there is a problem in a certain process! Take me to the production workshop to have a look."

Without hesitation, Wei Yu got up and left.Now 1 minute is very precious. Due to the existence of errors, two people have been forced to suspend work temporarily, waiting for the results of troubleshooting.And there are not many people who can produce in total... So, after such a stop, the speed has slowed down significantly.

If it weren't for Qin Mu's strategy just now that might reduce the production pressure in the future, Wei Yu didn't even know what to do.

However, it will take a certain amount of time for that strategy to take effect. Before that, all the railway laying basically relied on the Royal Workshop.

After entering the workshop, two burly men greeted him immediately.

Qin Mu looked over, and saw that the two men had dark complexions, obvious muscles, and many burn marks on their bodies. They should be the two craftsmen who were forced to stop working due to errors.

Besides them, there are more than a dozen people in this workshop who are working hard, and even Wei Yu didn't bother to raise his head to say hello when he came.

Wei Yu seemed to have gotten used to this, worried that Qin Mu and the others might misunderstand, and specifically explained: "I have specifically said hello, the production of ironware cannot be stopped! Once it stops, the molten iron will solidify and can only be discarded! Therefore, They won't come now!"

After the two blacksmiths arrived, they also saluted Wei Yu and the others, and then stood aside.

In fact, Wei Yu's interactions with them are far less formal.Before he became the Shaofu, he spent half his life in this workshop and knew everyone very well.

Although he was the deputy of the former Shaofu, he was not a nobleman, he didn't have any official airs, and he was kind to everyone, and he really understood these techniques, so he was very much supported by these craftsmen.

Therefore, even now that he has become a Shaofu, his relationship with everyone has not changed much.When the new craftsmen saw him calling Mr. Shaofu, the old craftsmen called Shunzui, and sometimes they called Old Wei, and he happily agreed.

Today's situation is purely because Wei Yu specifically explained that they must pay attention to their words and deeds today, talk less, watch less, listen less, and do more.After all, Zulong and Qin Mu came here together, Wei Yu was afraid that these craftsmen would accidentally offend these two!If that's the case, let alone themselves, they will be buried with their family members, which is just a matter of these two words.

These blacksmiths usually do physical work, and they don't care about meat and vegetables, which is a good thing to say the least.

Qin Mu glanced at them, and pointed to a random person: "Come here, make a rail according to the previous method, and I'll take a look."

The man nodded, and came to an empty blast furnace, which should be the place where he worked before, and handled the tools very skillfully.

His apprentice hurriedly followed and helped the master.First, the blast furnace was turned on, and the red molten steel flowed out, which was skillfully led into the mold by the blacksmith, and then began to wait for the mold to cool down. After cooling down, it was put aside for cooling. , occasionally sprinkled with a little water.

After this process, there is no problem in operation.After all, he is also an old blacksmith carefully selected by Wei Yu. Qin Mu knows that the probability of operation problems is relatively small.

He took a closer look at the condition of the blast furnace, and there was nothing wrong with it.The wooden basin in the apprentice's hand and the water it holds are no different from those of other people.When sprinkling water, the method is very casual, and the water will not be sprayed in a certain place.

This……

Qin Mu cast his eyes on their molds.

The mold here is still an earthen mold inherited from the bronze casting technology. In order to adapt to repeated use, it was fired with clay.

The problem should be here.... . . . .
