Definition
melting furnace lining 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.
Feature
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.

With the company healthy and fast development,melting furnace lining mass had been sold to all over the country, such as Vietnam, India, Korea, Pakistan, kazakhstan, Iran and other southeast Asian countries and regions.
Application
melting furnace lining 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.
