Chinese corundum refractory castable.

A refractory castable prepared with corundum as aggregate and powder plus some binders. It has higher mechanical strength and anti-abrasion performance than high-aluminum refractory castable and mullite refractory castable, but its thermal shock resistance is slightly worse. Mainly used as lining material for boilers, blast furnace hot blast stoves, heating furnaces, ceramic kilns, etc.

Corundum products are made of refractory products with Al2O3 content greater than 90% and corundum as the main crystal phase, mixed with appropriate amount of dispersant, coagulant, stainless steel fiber, and compounded according to strict formula. It has many characteristics such as good high temperature strength, abrasion resistance, erosion resistance, high thermal conductivity, thermal shock resistance, corrosion resistance, good sealing performance, rapid setting and early strength. Products are widely used in circulating fluidized bed boilers, metallurgy, petrochemical, thermal power and other industries. The tenet of our company is to survive by quality, progress by science and technology, and benefit by management.

(1) Adding a certain proportion of steel fiber and additives to the castable can produce steel fiber castable with good thermal stability and strong wear resistance, which can be used for heating furnace hearth, tapping trough and cement rotary kiln mouth And other parts.

(2) According to user requirements, choosing this series of castables can process various prefabricated components with drawings

Corundum castable The corundum-based refractory castable is compounded with fused corundum as the main raw material, with a variety of ultra-fine and high-efficiency additives. The main features are high strength, good volume stability, excellent corrosion resistance, and are not affected by reducing gases such as H2 and CO. The quality product is made of refractory products with Al2O3 content greater than 90% and corundum as the main crystal phase, mixed with appropriate dispersant, coagulant, stainless steel fiber, and compounded according to strict formula. Among them, the chemical composition is Al2O3, SiO2, the grades are GJ-180, GJ-18S, the explosion-proof GJ-180F and KT-185 also contain a small amount of Fe2O3
