Light casting material refractory cement
Amorphous lightweight insulation refractories refractory cement have been widely used by users,The application of thermal insulation refractories has developed to amorphous lightweight insulation refractories refractory cement.Because it has:Small volume density, low thermal conductivity, can reduce equipment weight,Good insulation properties, the uniform temperature, save energy and  refractory cementwith high strength, strong overall performance, spalling resistance performance, long service life,Any repair processing of various shapes or whole lining.The construction is simple and the cost is low.Now widely used in metallurgy, machinery, electricity, chemical, petroleum and other industries of industrial furnaces and thermal equipment, energy saving than ordinary refractory 20%.

usage method
First mold and pouring contact surface clean, in the pouring material refractory cement to add water to its moisture content 42-45% mixing can be poured 24 hours after stripping,Hang the plastic film of natural health 2-3 days after the ignition oven,Castable containing large amounts of bound water and free water, pay attention to the control of heating oven,In particular, when the temperature of 120℃、350℃、600℃、800℃ degrees to slow, there must be a certain heat preservation time.Recommended not less than 48 hours below 120 degrees, not less than 350 hours below the temperature of 96 hours, after heating hourly 20-30 C, until the temperature.
