Shanghai is prosperous

Chapter 376

On the afternoon of the eighth day of the Lunar New Year, Wang Yiyuan arrived at the factory.This time I went to Tangshan, because it was not easy to buy train tickets, so I had to go to Tianjin first, and then transfer to Tangshan.Instead of asking Li Guanglin to pick him up at the train station, he took a taxi directly to the factory.

After seeing all the workshops, Wang Yiyuan was very satisfied with Wang Liping's work efficiency.In such a short period of three or four days, he was very surprised and satisfied to be able to organize a factory that was originally a mess into what it is today.

Lao Yu was not at the factory.Wang Liping said that Lao Yu went back to his hometown in Zunhua yesterday, saying that he would not come back until around the tenth day of the Lunar New Year.

Wang Yiyuan asked, Lao Yu's hometown is in Zunhua?I remember that he used to say that he was an employee of Kailuan Coal Mine and that he opened a factory here, so I thought he was from Kaiping.Didn't he say anything when he handed over to you?

No.It's the draft contract you gave me. After reading it, he didn't say that he had any disagreements.I also asked him specifically, and he said that he basically agreed with what we wrote above.

I still want to meet him this time.Wang Yiyuan smiled and said, this is also a very interesting old man. He put down the factory that he had worked so hard for several years, which is not something ordinary people can do.

What is particularly surprising is that the workshop for baking flowers has been basically set up.There are two workers in the workshop who are busy with decals, and the kiln is heating and baking flowers.

Master Zhang is also in the workshop.Today, the Kaiping Porcelain Factory where he works started construction, and he went to the unit to report an arrival in the morning.Because it was the first day and there was nothing specific about work, so he came here again in the afternoon to help and guide Li Guanglin in installing and firing the kiln.

The flowers posted in the morning have all been packed into the kiln.Master Zhang looked at the time and said, the temperature is about 780 degrees, and after another 10 minutes of keeping warm, the kiln will automatically cut off the power, the kiln will start to cool down, and the temperature will drop.If you want to see the finished product, it will take less than two and a half hours.

Wang Yiyuan smiled and said, Master Zhang is so much trouble, we are all newbies, please teach us more.Hehe, I hope this kiln can bake flowers to a full house.

Master Zhang said that baking flowers should not be a big problem, as long as the flower paper is good, the decals can be pasted in place, the tires should be wiped clean, and then be careful when installing the kiln.As for the grilling process, it is not like pixel firing or glaze firing, basically as long as the temperature setting is about the same.

Wang Liping said next to him, that is to say, doing it by ourselves is very different from doing it by others, and we are very nervous.

Master Zhang smiled and said, it is right for you to bake the flowers first.We make ceramics, especially in cold weather, what ceramic factories need most is temperature.Take a look at the small ceramic factories in Tangshan. Generally, the workshops are not very spacious, and the height is not very high, and the entire factory building is tightly wrapped. There is a reason for this.

Why is this again?
Master Zhang said that the truth is actually very simple.The entire ceramic production process requires a certain ambient temperature.Whether it is pressure grouting, embryo repair, glaze spraying and other processes, heat is indispensable.Especially the work of pressure grouting, if there is no ambient temperature, it cannot be shaped at all, and there is no way to continue production.Also, the drying and heating of this ceramic model requires temperature.

Wang Yiyuan suddenly realized, and said, it turned out to be like this.In the past, I saw that many ceramic factories used tarpaulin or even film to enclose the workshop. I still don't understand why they do this. I think it is neither beautiful nor safe.

Master Zhang said that the reason why they closed the workshop tightly is to maximize the use of the hot air discharged from the kiln for the longest period of time, so as to save costs.

Wang Liping smiled and said, it's the same.In this winter, if there is no heat in the workshop, how can the workers do their work, and the damage rate can't rise "sizzling"?

Master Zhang said that the same is true for other workshops.Although it seems a bit cold now, as long as these kilns are used, the whole workshop will be very warm.The production of the factory does not require additional heating or anything, as long as the waste heat of these kilns is used well, it is basically enough.

While talking, Li Guanglin came back with a cart full of plaster casts.Wang Yiyuan unloaded the truck with him, and moved the models one by one onto the shelves in the drying room, stacking them neatly layer by layer.

Master Zhang opened the upper and lower covers of the plaster model, looked at it, and put his hands on the model to feel it, and said, um, put these models in the drying room for another night, and they can be used tomorrow.

He asked again, are you going to inject mud?Now that the weather is so cold, the mud also needs to be heated in the drying room.

Wang Liping said next to her that she had already called the mud factory, and they would send two barrels over for trial in a while.

Master Zhang asked, whose mud do you want now?
Wang Liping replied that it was the same mud factory that Lao Yu had used before.Lao Yu recommended it, saying that they used it well before.

Master Zhang said that it doesn’t matter which company’s clay you use, the key is as long as it is easy to use.How to use it is very simple. We mainly look at two points, one is the survival rate and water content, and the other is the quality of the fired product, including the quality of biscuit firing and glaze firing.

He said that as long as one or two kiln products are produced, the quality of the mud can be judged.If you feel that it is not working, you must replace the mud manufacturer in time.However, there are many mud factories in Tangshan, and there is a lot of room for choice, so there is no need to worry.

The models are all placed.The kiln for baking flowers has been kept warm, and the power will be automatically cut off.The temperature displayed by the thermometer on the meter box began to drop gradually by one degree.

Master Zhang said that when the temperature drops to 550 degrees, you can open the kiln door to make the heat dissipation faster.Then gradually open the kiln door wider according to the drop in temperature.This not only cools down faster, but early exhaust is also good for the baked products inside.

About another hour later, the displayed temperature had reached fifty or sixty degrees.Master Zhang said that the kiln door can be fully opened now.

He instructed Li Guanglin to go up and open all the kiln doors. After drying for a while, he began to instruct Li Guanglin to open the kiln and take out the roasted waist plates one by one.

While Li Guanglin was starting the kiln, Master Zhang was checking the status of the roasted flowers one by one.

After all the kilns were opened for play, Zhang Shichuan concluded that overall, the effect of this kiln for baking flowers is still very good.That is to say, the temperature and heat preservation time we set are correct, so we don’t need to adjust them any more, just continue baking flowers according to the current parameters.

However, there are still some flaws and defective products.He took a few samples and called Wang Yiyuan and the others to take a closer look at the defects under the fluorescent lamp.

Master Zhang said that there are mainly two places that need attention.One is the baked flower sticking glaze, just like this, there are colored stains and glaze damage on the glaze surface.The second is that the flower paper interface is not very tight, and there are occasional flower bursts on some waist plates.

Wang Liping asked, how should it be resolved?

Master Zhang said that the first phenomenon is mainly because the kiln is not installed neatly, or because of excessive vibration, the ceramics are skewed and leaned against each other, so that the pigment on the baked pattern sticks to another ceramic.

Therefore, when installing the kiln, it must be upright, straight and neat, and not skewed.Master Zhang said that the kiln should not be too dense. If the density is too high, the temperature distribution in the kiln will be uneven, which will affect the quality of the baked flowers.

He said, in addition, when decals should be carefully scraped off, the water should be drained.The water used to soak flower paper should be changed frequently.In addition, when wiping the tires, you must not only wipe them clean, but also pay attention to the uniform force, so as not to damage the original position of the decal paper.
