MgO-CaO Brick/Strong fire resistance/Excellent thermal insulation/Good environmental performance
MgO-CaO Brick
Summary:
MgO-CaO Brick is made of two-step calcined magnesium calcium sand and high quality high purity (electromelting or sintering) magnesia as raw materials, made of high pressure molding, high temperature sintering, vacuum dipping, and has excellent high temperature creep and slag resistance performance, and is the ideal environmental protection material for AOD and VOD refining furnace.
Product features:
- 1.Strong fire resistance: MgO-CaO Brick Material can withstand high temperature, can be used in the manufacturing of high temperature equipment
- 2.Thermal insulation, heat insulation effect is good: because the thermal conductivity of MgO-CaO Brick is small, so it has a very good thermal insulation, heat insulation effect
- 3.Good environmental performance: MgO-CaO Brick does not contain harmful substances to human body, so it becomes a safe, environmentally friendly new material
Range of application:Used for AOD, VOD refining furnace
