Anorthite Insulating Fire Brick used as hot face refractory lining or back-up insulation in various industries, such as:

• Chemical & Petrochemical: Kilns, flues, refining vessels, heaters, reactor chambers.
• Glass: Melters, regenerators, tin baths, distributors, tempering furnaces.
• Ceramics: Roller kilns, tunnel kilns, shuttle kilns, electricity furnace.
• Aluminum: Anode baking furnaces, aluminum electrolytic cells.
• Lithium-ion Battery: Cathode and anode furnaces.
• Iron & Steel: blast furnaces, hot blast stoves, reheating furnaces, bright metal annealing furnaces.
• Industrial Furnaces: Electricity furnace, carburizing furnaces, heat treating furnaces, electronic product furnaces, refractory sintering furnaces

The image on the right compares the pore size distribution of traditional extruded insulating bricks and insulating bricks produced by the slurry foaming casting method, as observed under an electron microscope. The comparison reveals that the pore size of bricks produced by the slurry foaming casting method is significantly smaller than that of extruded insulating bricks. These micro-pores reduce conduction, convection, and radiation during energy transfer, resulting in a much lower thermal conductivity. This greatly enhances the energy saving potential of the kiln.
