Blast furnace slag treatment system is an important part of ironmaking, before 2006, the domestic blast furnace slag treatment system used manganese steel plate or cast steel liner, since 2007, Tangshan Steel 3200M3 blast furnace granulation tower and slag ditch for the first time to use our company's high-strength ceramic wear-resistant material as a liner, the domestic blast furnace slag treatment system appeared revolutionary innovation, pioneering the slag treatment system to use the ceramic wear-resistant material as a liner.

Since 2007, more than 400 blast furnace slag treatment systems in China have adopted the ceramic wear-resistant materials produced by our company (Wear-resistant Material Patent Certificate No.: ZL200710189737.2), realizing the safety and longevity of blast furnace slag treatment system. It avoids frequent maintenance and brings considerable economic benefits to the ironworks.
