Ladle Working Layer Gunning Mix for Steel Industry
Application Industry: Refractories for Steel Industry
Application Equipment: Ladle Working Layer Surface Repair by Gunning Method
Size: Pre-mixed granular gunning material with custom grain size (free engineering on request)
Products Overview
Our Ladle Working Layer Gunning Mix is a refractory gunning product engineered for ladle working layer surface repair by gunning method. The product family is manufactured from high-purity corundum and magnesium aluminate spinel as the main raw materials, featuring wet spraying technique for ladle working layer surface application. The product shows no pollution to environment and no CO2 or CO gas produced during ladle production and use.
The Ladle Working Layer Gunning Mix product family is offered in two engineering-proven GBP chemistry grades. The CH-GBP85 grade features alumina content minimum 85%, apparent porosity maximum 12%, bulk density minimum 2.80 g/cm³, cold crushing strength minimum 60 MPa, and permanent linear change 0 to +1.5 percent after 1550 °C firing for 3 hours. The CH-GBP88 grade features alumina content minimum 88%, apparent porosity maximum 11%, bulk density minimum 2.90 g/cm³, cold crushing strength minimum 70 MPa, and permanent linear change 0 to +1.5 percent after 1550 °C firing for 3 hours.
Sourced from our Xinmi City, Zhengzhou, Henan, China facility, each Ladle Working Layer Gunning Mix grade is engineered to ASTM, GB/T, and ISO refractory standards.

Product Applications
Ladle Working Layer Gunning Mix is a refractory gunning product manufactured from high-purity corundum and magnesium aluminate spinel as the main raw materials, engineered for ladle working layer surface repair by gunning method. The product family features wet spraying technique with no pollution to environment and no CO2 or CO gas produced during ladle production and use, ensuring a carbon-free and environment-friendly ladle operation.
Application Industry: Refractories for the Steel Industry and the broader Metallurgical Industry.
Target Equipment: Ladle Working Layer Surface of small, medium-size, and large ladles in steelmaking operations.
Specific Application Zones: The CH-GBP85 grade (alumina content minimum 85%, apparent porosity maximum 12%, bulk density minimum 2.80 g/cm³, cold crushing strength minimum 60 MPa) is the standard variant for ladle working layer surface gunning repair. The CH-GBP88 grade (alumina content minimum 88%, apparent porosity maximum 11%, bulk density minimum 2.90 g/cm³, cold crushing strength minimum 70 MPa) is the high-alumina workhorse for demanding ladle working layer surface gunning repair. Both grades deliver permanent linear change 0 to +1.5 percent after 1550 °C firing for 3 hours. The product family can be endlessly cycle used to lower the refractory materials consumption and waste appearance, working with key role on the ladle continue and safety use.
