Product Overview
Description
Introduction of corundum mullite insulating brick
The corundum mullite insulating brick products use imported tabular corundum and high-purity fused corundum as the main raw materials, and adopt advanced superfine powder adding technology. After mixing, forming, drying, and firing at high temperature in shuttle kiln. When the corundum mullite brick is produced, a certain thickness of thermal insulation material is designed and produced on its non-working surface according to the conditions of use.
Refractory Corundum Mullite Brick adopts special production technology to combine two different materials into a whole. Under the premise of ensuring no fracture and keeping the thermal expansion rate close to the same, the corundum mullite brick has high temperature resistance, corrosion resistance, The effect of high strength and erosion resistance can effectively solve the problem that double-layer masonry of thermal insulation materials cannot be used in the lining of the rotary kiln.

Advantage of corundum mullite insulating brick
1. Mullite Insulation Refractory Brick has the characteristics of high refractoriness and good thermal shock stability
2, high temperature strength, excellent corrosion resistance, strong slag resistance
3. With the characteristics of small expansion coefficient, low creep, and resistance to spalling, corundum mullite bricks are suitable for the use of high-temperature kilns under various conditions
