JM insulating firebrick
MOQ: 5 tons
Description
JM insulating firebrick puts alumina as main materials. After extrusion molding, they are fired at high temperature. Each surface of the brick is mechanically polished to the required size. Insulating firebricks can reduce the cost of the foundation, reduce the cross-section of the frame, and save reinforced concrete can significantly save the comprehensive cost of the building. It's a necessary refractory bricks for us to use in various kinds of furnace such as chemical industry,glass foundry and so on. These JM insulating firebrick does well in energy saving and heat preservation. The tolerance of temperature is from 1300 to 1400 degrees.
Features
JM insulating firebrick has a high heat preservation effect, strong durability, high mechanical intensity, great energy-saving insulation, and high cold crushing strength.
Application
JM insulating firebrick can be used to replace lightweight burner bricks, high temperature furnace burner brackets, and refractory linings or insulation layers in addition to being directly placed to such surfaces. widely applicable as a backup insulation material for high temperature processing of metals, petrochemicals, and ceramics or in hot face refractory lining.
