Steel fiber wear-resistant castables are mainly made of steel fiber, refractory aggregate, binder and other additives.
Special grade bauxite clinker is usually used. Steel fiber is mostly heat-resistant stainless steel fiber, and its addition amount is generally in the range of 0.6%-2.5% by volume.
Steel fiber can significantly improve the toughness, impact resistance and wear resistance of the castable, while inhibiting the shrinkage of the castable after curing, drying and heat treatment.
(1) Good wear resistance
(2) High compressive strength
(3) High flexural strength
(4) Good thermal shock resistance
(5) Easy construction
Steel fiber wear-resistant castables are widely used in high-temperature furnaces and equipment in metallurgy, mining, electric power, chemical industry, building materials and other industries
