Jiacheng graphite crucible is a tool that can transfer heat in casting. It has good thermal conductivity and high temperature resistance. With such excellent characteristics, it plays a very important role in metallurgy, casting, chemical industry and other industries. Graphite crucible is made of a variety of excellent refractories, which are processed by mixing and have good advantages of high temperature resistance On the one hand, the advantages are very important in the smelting industry, which shows that various metals can be smelted, including common metals such as stainless steel, iron, copper, aluminum, gold, silver lead, zinc and alloy. Next, Jiacheng graphite crucible manufacturer will give you a detailed introduction of graphite crucible resistance.

The answer to this question is that it can be melted, there is no problem at all. The melting point of iron is 1538 degrees. When it reaches this temperature, the iron metal will melt, and the resistance temperature of graphite crucible is about 1680 degrees, that is to say, the surface graphite crucible can withstand the melting temperature of iron. And the graphite crucible has many specifications and sizes, the small one is No. 1, the large one is No. 2000, which can meet different furnace types, including resistance furnace, medium frequency furnace, induction furnace, etc. At present, there are many enterprises using graphite crucible to smelt iron in the market to do experiments and to keep samples.

Instructions for use of Jiacheng graphite crucible:

Jiacheng graphite crucible is a kind of crucible with excellent performance. This excellent performance comes from the excellent raw material silicon carbide. The chemical formula of silicon carbide is SiC, which is a chemical hexagonal crystal with stable structure. Silicon carbide is made of quartz sand, coal coke, wood chips and other raw materials by smelting in the high temperature environment of resistance furnace. It is widely used and economic in the contemporary refractories A kind of raw material, sublimated under low pressure, the sublimation temperature is 2200 ℃, different from general materials, when the temperature is increased, the silicon carbide crucible will not soften, but its strength will increase, and when the temperature is 2500 ℃, its tensile strength will double. The special thermal shock resistance, the thermal expansion of silicon carbide graphite crucible are anisotropic, so the macro expansion coefficient is not large, and in the case of temperature sudden change The volume of graphite crucible has little change, and its good thermal conductivity, therefore, the thermal shock resistance of silicon carbide crucible is good, and it should be able to work stably at high temperature for a long time.

Jiacheng graphite crucible manufacturer will tell you the use skills, especially how to preheat and dry:

1. Different silicon carbide graphite crucibles should be preheated to about 200 ℃ for about 30 minutes when they are used for the first time. In addition, it needs to be dried for 60 minutes. Rotation is also required during this time. Ensure that the silicon carbide graphite crucible can be evenly heated.

2. After preheating, the silicon carbide crucible shall be heated to 900 ℃ - 1000 ℃ (about 2 hours) as soon as possible, and kept warm for 20-30 minutes, then raised or lowered to the working temperature.
