Wear-Resistant Refractory Castable

Wear-resistant refractory castable is a monolithic refractory material made from high-alumina aggregates, corundum, silicon carbide, and other high-hardness wear-resistant raw materials, combined with high-quality binders and additives. It is installed by on-site mixing with water and casting into place, forming a dense and integral lining structure.This product is widely used in high-temperature environments with severe abrasion, strong erosion, and particle impact conditions.Excellent Wear ResistanceHigh-hardness aggregates effectively resist material abrasion, particle impact, and mechanical erosion, significantly extending lining service life.High RefractorinessWorking temperature can reach 1300°C – 1600°C, suitable for a wide range of industrial furnaces and kilns.Strong Erosion ResistanceDesigned for high-velocity gas flow and heavy dust or particle environments, ensuring stable long-term performance.Good Thermal Shock ResistancePerforms well under frequent heating and cooling cycles, reducing cracking and spalling risks.Monolithic StructureSeamless cast lining reduces weak joints, minimizes heat loss, and improves overall structural integrity.Typical ApplicationsCement rotary kiln systems (preheater, tertiary air duct, grate cooler)Circulating Fluidized Bed (CFB) boilersPower plant boilersSteel reheating and heat treatment furnacesWaste incineration furnacesChemical high-temperature reactorsMetallurgical and industrial wear-prone equipmentAdvantages✔ Extended service life of kiln lining✔ Reduced maintenance frequency✔ Lower downtime and production loss✔ Improved operational stability✔ Reduced overall operating costsConstruction MethodMix with water → Casting → Vibration compaction → Curing → Drying & heat-up before operationSupply & CustomizationWe provide customized formulations based on working temperature, abrasion intensity, and chemical conditions to meet different industrial requirements.Manufacturer InformationXinxiang Tianyi Insulation Materials Co., Ltd. specializes in the R&D and production of high-performance refractory and thermal insulation materials, providing reliable kiln lining solutions for global industrial customers.
