HUAO Black Sic Silicon Carbide for Smelting
It is used for deoxidizing. The usage dose is 1-4kg/t can make electricity consumption to reduce 15-20kw/h and time to reduce 15-20min per furnace to raise productivity rate to 8-10%.
Description
Technical Parameters
Introduce
Silicon carbide was fused by heating high purity silicon sand and carbon in electrode furnace above 2500 ºC. It is the hardest blasting media available. High-quality silicon carbide media is manufactured to a blocky grain shape that splinters.
It is used for deoxidizing. The usage dose is 1-4kg/t can make electricity consumption to reduce 15-20kw/h and time to reduce 15-20min per furnace to raise productivity rate to 8-10%. Applications 1. Silicon carbon can be used as metallurgical deoxidizer and high temperature resistant materials in smelting. 2. It can also be used as abrasive materials,which can be used to make abrasive tools,such as sand paper, abrasive cloth, grinding wheels, oilstones and so on. 3. For refractory material in ceramic production.
