Introduction
Torpedo car wet shotcreting castables are engineered for rapid inner lining repair without mould requirements. Manufactured from premium high-alumina, fused alumina and silicon carbide, the material offers good flowability for pumpable delivery through shotcreting equipment. It hardens quickly with high strength, delivering excellent resistance against erosion and thermal shock. Grade JH-PS65 features Al₂O₃ ≥65% and SiC+C ≥5%. The wet-mix process significantly reduces dust during application, and field trials have demonstrated approximately 30% increase in torpedo car service life.
Key Advantages
01
Fast Hardening & High Strength
Hardens rapidly after application with cold crushing strength ≥60 MPa at 1450℃, enabling quick return to service and reducing repair downtime.
02
Excellent Erosion & Thermal Shock Resistance
Resists molten iron erosion and withstands rapid temperature fluctuations during torpedo car operation, significantly extending lining service life.
03
Mould
Free & Low-Dust Application – Wet shotcreting process eliminates mould requirements and minimises dust generation, improving construction efficiency and workplace safety.
