customize clay silicon carbide crucible for smelting

When used for the first time, under the condition of no feeding, the silicon carbide crucible is preheated to 150-200 degrees and kept for one hour. Because the crucible wall is rapidly oxidized in the temperature range of 315-650 degrees, silicon carbide crucible for smelting cannot be preheated in this temperature range, and there is no need to stay in this temperature range for too long.Mishan can customize silicon carbide crucible as client’s requirement.

For melting metal, What's the temperature application?  For clay silicon carbide crucible,Zinc Alloy: 450-550 ℃ ,Aluminum Alloy: 620 -900 ℃ ,  Above 1000 ℃ (Zinc Oxide, Copper alloy, Precious Metal) 

Heating graphite crucible to make its temperature higher than the normal operating temperature will extend the service life of the graphite crucible. Heating Graphite Melting Crucible to 815-930 degrees will generally assist in the protection of the crucible's glaze. If possible, this high temperature heating can be carried out weekly.Small Graphite Crucible and Large Graphite Crucible also can be customed in MIshan factory, graphite mold including Graphite Round,Graphite Rod, Graphite Plate, Graphite Ring,Graphite Tube,Graphite Ingot Molds,Graphite Nuts & Bolts,High Temperature Resistance Graphite Heater For Furnuce and Graphite Electrode are main products in our factory.
