Supply High alumina corundum and spinel fused high purity magnesite Corundum Ramming Mass

Product Description

Ramming Mass Product Introduction:
Refractory alumina ramming mass is an unshaped refractory material which is prepared by ramming (manual or mechanical) method and hardened by heating at a higher temperature.Ramming materials into acid, neutral, alkaline three.

Ramming Mass Application:
Refractory alumina ramming mass are divided into neutral ramming materials. It is used as the lining of coreless medium frequency furnace and cored induction furnace. It is very suitable for melting gray cast iron, cast iron alloy, melting carbon steel, alloy steel, high manganese steel, stainless steel, melting aluminum and its alloy, melting copper, brass, white copper and bronze and other copper alloys.

Ramming Mass Features:

1.On the face in contact with liquid metal there is a dense sintered layer where tightness of liquid metal is quite perfect.
2.Thermal conductivity is lower than other refractoriness so the Thermal loses are less than any other kind of refractory.
3.Good resistance to temperature change.
4.Low cost in furnace lining.
5.Short heating and sintering time through dry preparation Of masses.
