8% Refractory black silicon carbide grit ceramic raw materials producers for abrasives

8% Refractory black silicon carbide grit ceramic raw materials producers for abrasives is produced at high temperature in an electric resistance type furnace with quarts sand and petroleum coke as its main raw materials .Its hardness is between fused alumina and synthetic diamond.Mechanical intensity of it is higher than fused alumina .It is brittle and sharp has electrical and heat conductivity in some degree.The abrasives made of it are suitable for working on cast iron,non-ferrous metal,rock, leather,rubber,etc.It is also broadly used as refractory material and metallurgical additive. excellent thermal volume stability and thermal shock characteristics can be attributed to its specific microstructure: low open porosity and large crystals with closed spherical pores,which are entrapped upon re-crystallization during rapid sintering.

Product feature:

high temperature performance and high-density, strong anti-permeability ability and easy to rapid sintering, very thin sintered layer,good thermal shock stability, strong slag-resistance, long service life .

Product function:

Apply to the construction of bottom and wall of all kinds steel making electric arc furnace and ferroalloy smelting furnace for hot charging of hot metal and second hand steel.

Product usage:

Mainly used in producing common magnesite brick, magnesite aluminum brick, magnesite chrome brick, gunning mix, hot patching mix for converter and EAF ect .

Product Advantage:

Our factory produce the products of the Dead-burned magnesite are selected natural magnesite, it is produced by mine-selecting, purifying, calcimine in shaft kiln. It is an ideal material for unshaped refractory material, the final products are used in open hearth furnace, electric furnace bottom and furnace's lining tamping.
