High Alumina insulation firebrick

High Alumina insulation firebrick

 
High Alumina insulation firebricks are sintered mainly with supper-fine bauxite chamotte, and proper additive by a method of EPS ignition loss, their main advantages include high intensity, low thermal conductivity, excellent thermal stability, very small reheat linear change, outstands erosion and corrosion resistance etc. They are an ideal kind of energy-conserning products which can be widely used as lining or insulating layers of various industrial furnaces and kilns in metallurgical industry, machine building industry, ceramic industry, chemical industry, etc. Recommended service temperature: less than 1400℃.
