Water-Free Patching Mixes for Blast Furnace
Application Industry: Refractories for Steel Industry
Application Equipment: Blast Furnace Cooling Stave, Furnace Shell, and Bottom Cover Plate
Size: 100 percent passing 1.5 mm or 1.0 mm sieve (per grade)
Products Overview
Our Water-Free Patching Mixes for Blast Furnace are refractory patching compounds manufactured from electric calcined anthracite and high-quality bauxite clinkers bonded by phenolic resin, with specialty curing agents added. The product is engineered to fill up the gap between the blast furnace cooling staves and the furnace shell, and the gap between the bottom cover plate and the carbonaceous ramming layer, delivering easy construction, full gap filling, good integrity, and high strength after low-temperature curing.
The Water-Free Patching Mixes for Blast Furnace product family is offered in two grades (CH-WYLB and CH-WYLD) covering a wide chemistry range. The CH-WYLB grade is the alumina-rich option with alumina content over 92 percent and low iron oxide content under 2 percent, designed for filling the gap between the blast furnace cooling staves and the furnace shell. The CH-WYLD grade is the carbon-rich option with carbon content over 80 percent and lower bulk density, designed for filling the gap between the bottom cover plate and the carbonaceous ramming layer.
Sourced from our Xinmi City, Zhengzhou, Henan, China facility, each Water-Free Patching Mixes for Blast Furnace is engineered to ASTM, GB/T, and ISO refractory standards.

Product Applications
Water-Free Patching Mixes for Blast Furnace are phenolic resin-bonded refractory patching compounds manufactured from electric calcined anthracite and high-quality bauxite clinkers, engineered for the steel industry gap-filling applications in blast furnace installation and maintenance. The product is characterized by easy construction, full gap filling, good integrity, and high strength after low-temperature curing.
Application Industry: Refractories for the Steel Industry and the broader Metallurgical Industry.
Target Equipment: Blast Furnace Cooling Stave Assembly, Furnace Shell, and Bottom Cover Plate of large Blast Furnaces.
Specific Application Zones: The CH-WYLB grade is the alumina-rich option for filling the gap between the blast furnace cooling staves and the furnace shell. The CH-WYLD grade is the carbon-rich option for filling the gap between the bottom cover plate and the carbonaceous ramming layer. Both grades are easy to construct, easy to fill up the gap, and deliver good integrity and high strength in the harsh blast furnace environment.
