Magnesia Mortar for Steel Industry
Application Industry: Refractories for Steel Industry
Application Equipment: Ladle and Converter Masonry Joints and Lining Service
Size: Pre-mixed mortar with 0 to 0.2 mm grain size (custom formulation on request)
Products Overview
Our Magnesia Mortar is a refractory mortar product engineered for ladle and converter masonry joints and lining service. The product family is manufactured from high-quality magnesite as the main raw material with chemical binding agent, showing excellent work ability, desirable hardening time, high adhesive strength, and good corrosion resistance under high-temperature molten steel conditions.
The Magnesia Mortar product family is offered in a single engineering-proven CH-DHN chemistry grade. The CH-DHN grade features MgO-Al2O3 content minimum 90%, grain size range 0 to 0.2 mm, hardening time 60 to 180 seconds, and adhesive strength minimum 1 MPa. The single-grade portfolio is engineered for optimal performance in ladle and converter masonry joints under demanding steel service conditions.
Sourced from our Xinmi City, Zhengzhou, Henan, China facility, each Magnesia Mortar grade is engineered to ASTM, GB/T, and ISO refractory standards.
