Refractory Mortar for Steel Industry
Application Industry: Refractories for Steel Industry
Application Equipment: Ladle Brick Masonry Joints and Brick Installation
Size: Pre-mixed refractory mortar with custom grain size (free engineering on request)
Products Overview
Our Refractory Mortar is a high-quality refractory mortar product engineered for ladle brick masonry joints and brick installation. Various kinds of refractory mortars are available at CH Refractories, which include corundum based, corundum Cr2O3 based, high alumina based, and Al2O3-MgO based. The mortars perform well in use with excellent workability, desirable hardening time, high adhesive strength, high strength, and corrosion resistance under high temperature.
The Refractory Mortar product family is offered in seven engineering-proven chemistry grades covering different raw material systems. The CH-GA88 grade features alumina content minimum 88% for high-alumina brick masonry joint service. The CH-GACr88 grade features Cr2O3+Al2O3 content minimum 88% for corundum-chrome brick masonry joint service. The CH-GM85 grade features MgO+Al2O3 content minimum 85% for magnesia-alumina brick masonry joint service. The CH-GMCr85 grade is engineered for additional chrome-enhanced performance. The CH-GT85 grade features alumina content minimum 85%, the CH-GT80 grade features alumina content minimum 80%, and the CH-GT70 grade features alumina content minimum 70% for varying masonry joint requirements. All seven grades deliver refractoriness minimum 1500-1690 °C, hardening time 60 to 180 seconds, and adhesive strength minimum 1 MPa.
Sourced from our Xinmi City, Zhengzhou, Henan, China facility, each Refractory Mortar grade is engineered to ASTM, GB/T, and ISO refractory standards.
