Graphite crucible

Graphite crucible, also calleSecurity Guard d copper melting bag and copper melting, is a kind of crucible made of graphite, clay, silica and paraffin stone as raw materials. Graphite crucible is mainly used to smelt nonferrous metals such as copper, brass, gold, silver, zinc and lead and their alloys.
The graphite crucible is made of natural flake graphite as the maMachinery for Packaging Supplies in raw material, and is made of plastic refractory clay or carbon binder. It has the characteristics of high temperature resistance, good thermal conductivity, good corrosion resistance, long service life and so on. In the process of high temperature use, the coefficient of thermal expansion is small, and it has a certain strain resistance to quench and heat. The corrosion resistHydraulic Press ance of acid and alkaline solution is strong, and it has excellent chemical stability, and does not participate in any chemical reaction in the melting process. The inner wall of the graphite crucible is smooth, and theRoadway Safety molten metal liquid is not easy to leak and adhere to the inner wall of the crucible, so that the metal liquid has good fluidity and casting property, and is suitable for casting and molding of various moulds. Graphite crucible is widely used in smelting alloy tool steel and smelting nonferrous metals and alloys because of its superior properties.

Graphite crucible Advatanges:

1.The high density of graphite crucible makes the crucible have the best thermal conductivity, and its thermal conductivity is obviously superior to other imported crucibles;
2.The graphite crucible has special glaze layer and compact molding material, which greatly improves the corrosion resistance and prolongs the service life of the product;
3.All graphite components in graphite crucible are made of natural graphite, and the thermal conductivity is very good. The graphite crucible can not be placed on the cold metal table immediately after heating so as to avoid its rupture due to rapid cooling.

Our graphite crucible is made from selective rWire Mesh aw material,and SURFACE anti oxidation ,Which improving the stability,delaying the corrosion and ensuring to keep the metal from being polluted by the graphite crucible.
