Product Description

graphite tube using in vacuum furnace

Product Description
Graphite crucible has good thermal conductivity and high temperature resistance. In the process of high temperature use, the thermal expansion coefficient is small, and it has certain strain resistance to rapid heat and quench. It has strong corrosion resistance to acid and alkaline solutions and excellent chemical stability. In metallurgical, foundry, mechanical, chemical and other industrial sectors, it is widely used in the smelting of alloy tool steels and the smelting of non-ferrous metals and their alloys, and has good technical and economic results. 

Features:
1. Graphite crucible has the best thermal conductivity because of its high density, and its thermal conductivity is obviously better than other imported crucibles.           
2. The surface of graphite crucible has special glaze and compact moulding material, which greatly improves the corrosion resistance of the product and prolongs its service life.           
3. Graphite in graphite crucible is made of natural graphite, and its thermal conductivity is very good. Graphite crucible should not be placed on a cold metal table immediately after heating to avoid its rupture due to rapid cooling.
