Precautions for using high-purity graphite crucible
Dec 04, 2022
In the metallurgical industry, high-purity graphite crucible has a very wide range of uses. Its main function is to store various liquid metals. As a metallurgical manufacturer, graphite crucibles will be used. Otherwise, there will be some problems in later use and production. Next Let's introduce what problems should be paid attention to when using high-purity graphite crucible.
1. The high-purity graphite crucible is relatively easy to be damp, and the product will become soft after being damp, and will be deformed when hit by some impactful objects, and once water enters the high-purity graphite crucible, it will affect the inside The raw materials in full bloom will cause the dilution of raw materials, and some chemical reactions will also occur to further affect its quality problems, so waterproof measures must be taken well.
2. Although the quality of the high-purity graphite crucible is very good and it is not easy to be damaged, it should be handled with care. Dropping from a high altitude or bumping and bumping has little effect on the quality of the graphite crucible, but if it continues for a long time, it will There is a phenomenon of cracks. After this situation occurs, there is no way to remedy it. It can only be replaced again.
3. Do not heat the high-purity graphite crucible on an open flame. Because its thermal conductivity is not particularly sufficient, it is meaningless to heat it on top, and it is unsightly to use smoke and fire to burn or let it appear black on the underside. Because the high-purity graphite crucible has good thermal conductivity and high temperature resistance, in high temperature use, the thermal expansion coefficient is small, it has a certain strain resistance to rapid heat and rapid cooling, and it has strong corrosion resistance to acid and alkali solvents. Good chemical stability. High-purity graphite crucible has a wide range of applications, mainly used for smelting various non-ferrous metals such as silver, aluminum, lead, copper, zinc, medium carbon steel and rare metals. The high-purity graphite crucible has stable quality, long service life, greatly reduces fuel consumption, reduces labor intensity, improves labor intensity, and creates better economic benefits.
