Environmental Friendly Taphole Clay
Application Industry: Refractories for Steel Industry
Application Equipment: Blast Furnace Taphole (Tapping Hole), Iron Runner Mud
Size: Standard taphole diameter per blast furnace (custom formulation on request)
Products Overview
Our Environmental Friendly Taphole Clay is a refractory taphole mud manufactured from corundum, alumina-silica based materials, SiC, and coke as the main raw materials, bonded by resin. The product family is engineered for Blast Furnace taphole service with low environmental impact, delivering good filling-up, easy installation, easy sintering, and easy opening under the harsh Blast Furnace Taphole service environment.
The Environmental Friendly Taphole Clay is one of three taphole clay grades offered by CH Refractories (Environmental Friendly, Waterless, and Water-Based), distinguished primarily by binding agent and alumina content. The Environmental Friendly Taphole Clay uses resin as the binding agent, the Waterless grade uses tar, and the Water-Based grade uses water. The Environmental Friendly Taphole Clay grade delivers alumina content of 27 percent or higher, silicon-carbide-plus-carbon content of 30 percent or higher, and moisture content below 0.5 percent, giving the highest density and lowest moisture in the taphole clay family.
Sourced from our Xinmi City, Zhengzhou, Henan, China facility, each Environmental Friendly Taphole Clay is engineered to ASTM, GB/T, and ISO refractory standards.
