Ramming mass for iron runner

2019-08-22


Main components:

Aluminum-silicon carbide-carbon-based ramming mass for iron runner of blast furnace is made of main raw materials including high-quality brown corundum, bauxite, silicon carbide and carbon materials, a variety of additives and imported resin.

Main features:

The ramming material has strong resistance to erosion and scouring of molten iron and slag, good thermal shock resistance, small volume change of reburning, non-slag iron, strong oxidation resistance and long service life. Because of its convenient construction and repair, the ramming material is widely used in the main runner, iron runner branch, slag runner and slag skimmer of small and medium-sized blast furnaces.
