Introduction
JinXin HengTuo manufactures high-performance alumina-silicon carbide mortar using premium alumina raw materials, silicon carbide and carbon-based materials. The product features appropriate setting time, high bonding strength and excellent performance at elevated temperatures. Available in both dry and wet forms to suit different construction requirements. Grade JH-HNSC offers Al₂O₃ ≥70% and SiC+C ≥8%. Widely used for laying and sealing refractory linings in hot metal ladles, torpedo cars, blast furnaces and hot blast stoves, ensuring secure brick adhesion and structural integrity under thermal stress.
Key Advantages
01
High Bonding Strength
Bonding strength reaches ≥1.0 MPa at 110℃ and ≥4.0 MPa at 1200℃, ensuring secure brick adhesion and joint integrity under thermal stress.
02
Controlled Setting Time
Setting time of 1–3 minutes provides adequate working time for bricklaying while preventing premature hardening during application.
03
Optimized Particle Grading
Fineness of <0.074mm ≥50% and <0.5mm ≤2% ensures uniform joint filling and excellent penetration into brick gaps.
