Latest company news about Graphite crucible is resistant to high temperature, high enough to melt iron

Jiacheng graphite crucible is a tool to 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 refractory materials after mixed processing. It has good advantages of high temperature resistance, which is very important On the one hand, its advantages are very important in the smelting industry, which shows that it can smelt all kinds of metals, including stainless steel, iron, copper, aluminum, gold, silver, lead, zinc and alloys. Now, 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. The temperature resistance of graphite crucible is about 1680 degrees, that is, the surface graphite crucible can withstand the temperature of iron melting. And the graphite crucible size is very large, small for No. 1, big for No. 2000, can meet different furnace type, including resistance furnace, medium frequency furnace, induction furnace, etc. At present, most of the enterprises using graphite crucible to smelt iron in the market are used to do experiments and keep samples.
Instructions for using Jiacheng graphite crucible:
Jiacheng graphite crucible is a kind of crucible with excellent performance. This excellent performance comes from the excellent raw material of silicon carbide. The chemical formula of silicon carbide is SiC, the chemical hexagonal crystal, stable structure. Silicon carbide is made of quartz sand, coal char, sawdust and other raw materials by smelting in high temperature environment of resistance furnace. It is widely used and more economical in contemporary refractories A kind of raw material, sublimated under low pressure, sublimation temperature is 2200 degrees, different from the general material, when the temperature rises, the strength of silicon carbide crucible not only does not soften, but also increases, when the temperature is 2500 degrees, the tensile strength is doubled, special thermal shock resistance, the thermal expansion of silicon carbide graphite crucible has anisotropy, so the macro expansion coefficient is small, in the case of sudden temperature change The volume of graphite crucible changes little, and its good thermal conductivity, so 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 how to use it, especially how to preheat and dry it
1. When different silicon carbide graphite crucibles are used for the first time, they should be preheated to about 200 ℃ for about 30 minutes. Another 60 minutes to dry. During this time, it needs to be rotated. Ensure that the silicon carbide graphite crucible can be heated evenly.
2. After preheating, the silicon carbide crucible should be heated to 900 ℃ - 1000 ℃ (about 2 hours) as soon as possible, kept for 20-30 minutes, and then raised or lowered to the working temperature.
Jiacheng graphite crucible manufacturers to share the above hope can help you, interested in more details welcome to call Jiacheng graphite crucible manufacturers, looking forward to your cooperation!
