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

Highland Refractory classifies Steel Fiber Wear Resistance Castable based on steel fiber content and matrix composition to adapt to varying wear-intensity scenarios, including High-Steel-Fiber Steel Fiber Wear Resistance Castable (steel fiber content 3-5%, ideal for ultra-high-wear zones like cement kiln tertiary air ducts) and Medium-Steel-Fiber Steel Fiber Wear Resistance Castable (steel fiber content 1-3%, suitable for intermediate-wear environments such as power plant boiler hoppers). There is also Low-Cement Steel Fiber Wear Resistance Castable (cement content ≤3%), designed for low-heat-release applications like waste incineration plant ash discharge channels—each type is formulated with high-purity aggregates (e.g., fused corundum, silicon carbide) and uniformly dispersed steel fibers, ensuring it maintains structural integrity under severe abrasion while withstanding temperatures ranging from 1200℃ to 1500℃.
Highland’s Steel Fiber Wear Resistance Castable stands out in harsh wear environments with core strengths: it exhibits exceptional wear resistance, with a wear loss rate 50-70% lower than traditional castables, significantly extending the service life of equipment like material conveying pipelines; the embedded steel fibers enhance its toughness and crack resistance, preventing structural damage caused by impact from hard materials (e.g., cement clinker or metal scraps); it also features good workability, allowing on-site casting into irregular shapes (such as furnace hoppers or chute linings) that prefabricated wear-resistant parts cannot match. These advantages make Steel Fiber Wear Resistance Castable a cost-effective solution for reducing maintenance frequency in high-wear industrial zones.
Steel Fiber Wear Resistance Castable is widely used across sectors requiring robust wear protection: in the cement industry, it lines cement kiln tertiary air ducts, cooler chutes, and raw material silo bottoms, resisting abrasion from hard clinker and raw materials; in the power industry, it serves as the lining for boiler ash hoppers and coal conveying pipelines, withstanding impact and friction from fly ash and coal particles; in the metallurgical industry, it is applied to steel mill slag conveying channels and tundish impact zones, enduring molten slag abrasion and mechanical impact; in waste incineration plants, it protects ash discharge chutes and furnace grates, resisting wear from corrosive and abrasive ash. Each application leverages Steel Fiber Wear Resistance Castable’s unique ability to combine high wear resistance and structural flexibility.
Steel Fiber Wear Resistance Castable (Highland) excels in targeted wear resistance and impact toughness, thanks to its embedded steel fibers and wear-resistant aggregate matrix, making it ideal for zones where material abrasion and impact are the primary challenges (like cement kiln chutes or power plant ash hoppers); Castable Solid, by contrast, specializes in versatile high-temperature performance and structural integrity, with a focus on adapting to diverse high-temperature environments (from steel ladles to glass furnaces) where general heat resistance and seamless lining formation are prioritized. Each product serves distinct needs: Steel Fiber Wear Resistance Castable dominates wear-prone, impact-heavy scenarios, while Castable Solid leads in general-purpose high-temperature lining tasks that require broad thermal and structural adaptability.
Highland Refractory is a trusted producer of high-quality Steel Fiber Wear Resistance Castable, backed by 30+ years of refractory expertise—we source high-strength stainless steel fibers and premium wear-resistant aggregates (fused corundum, silicon carbide), using advanced mixing technologies to ensure uniform fiber dispersion (avoiding clumping that reduces wear resistance); every batch of Steel Fiber Wear Resistance Castable undergoes strict quality testing, including wear loss measurement, impact strength tests, and high-temperature line change checks, meeting ISO 9001/CE standards. With an annual production capacity of 60,000 tons and services for 1,500+ clients across Asia, Africa, Europe, and Australia, we also tailor formulations (e.g., adjusting steel fiber content for specific wear levels) to match industry needs, ensuring reliable performance of our Steel Fiber Wear Resistance Castable.
Choosing Highland Refractory for your Steel Fiber Wear Resistance Castable needs means accessing tailored excellence and comprehensive support: we offer customization (adjusting steel fiber content, aggregate type, and setting time to fit your equipment—e.g., 5% steel fiber grades for ultra-high wear or low-cement grades for low-heat zones), fast delivery (3–7 days for standard types in stock, 10–15 days for custom formulations), and bulk discounts (5–10% off orders ≥8 tons). We also provide free samples, detailed technical data sheets (including wear resistance test reports and installation guidelines), and 24/7 technical guidance, ensuring your Steel Fiber Wear Resistance Castable integrates seamlessly into projects and delivers long-term wear protection in even the harshest industrial environments.
A: Yes, we do offer free samples of our Steel Fiber Wear Resistance Castable. You only need to cover the shipping cost to your address. For customized versions with specific steel fiber content or other enhanced features, a small charge may apply, but it will be refunded if you place a large order later.
A: If you order our standard Steel Fiber Wear Resistance Castable that's in stock, you can expect delivery within 3 - 7 days. However, for customized Steel Fiber Wear Resistance Castable with particular requirements like different aggregate compositions or improved crack - resistance, it will take 10 - 15 days as we'll need extra time for production and quality checks. For large - scale bulk orders, we'll work with you to determine a suitable delivery schedule.
A: Our Steel Fiber Wear Resistance Castable is packaged with great care. It is first sealed in moisture - proof bags to prevent moisture from affecting its setting and performance.
