Fused Cast AZS Block
Fused cast AZS block manufacturing process mixes selected zircon sand and industrial alumina powder at a ratio of 1:1, plus a small amount of Na2O (added in the form of sodium carbonate), B2O3 (added in the form of boric acid or borax) flux, and mix well After being melted at 1800~1900℃, it can be cast to form a fused-cast brick containing 33% ZrO2. On this basis, using partially desiliconized zircon sand as raw material, fused-cast bricks containing 36% to 41% ZrO2 can be produced. Zirconium corundum bricks use industrial alumina powder and selected zircon sand as raw materials to produce refractory products with a ZrO2 content of 33% to 45%.
Fused cast AZS block is an important refractory material to ensure the normal operation of glass melting furnaces. At present, glass melting furnaces increase the melting rate, extend the life of the furnace, and reduce fuel consumption mainly due to the use of this refractory material. -
Al2O3-SiC-C Brick
AI203-SiC-C brick, referred to as ASC brick. AI203-SiC-C brick is made of fused corundum (or sintered corundum, special grade bauxite clinker), graphite and silicon carbide with fixed carbon above 90%-95% as the main raw materials. It is made by adding graphite, bauxite, and additives, after batching, forming, drying and high temperature firing. ASC brick has very good high temperature performance and anti-oxidation, anti-flaking and anti-slag erosion properties, can withstand long-term high-temperature solution erosion, and has a long service life.

Silicon carbide brick
Silicon carbide bricks are made of silicon carbide as the main raw material, mixed with various binders according to requirements, and formed by high pressure. Silicon carbide bricks have high thermal conductivity, good wear resistance, thermal shock resistance, and corrosion resistance. They are ideal energy-saving materials for industrial kilns. It can be used for lining of aluminum electrolytic cell, molten aluminum pipe and kiln furniture for ceramic kiln, lower part of large and medium-sized blast furnace shaft, furnace waist and belly, aluminum refining furnace lining, zinc distillation tank lining, etc.
