#slag-blocking wool

Slag-blocking wool—a ceramic fiber blanket—is a soft, cotton-like felt with very low density and excellent slag-gathering properties. Crucially, it does not contaminate molten steel, and it is a neutral refractory material. When used, it is cut to the appropriate size according to requirements. After being placed on the surface of high-temperature molten steel, it softens and shrinks slightly, but this does not affect its ability to float on the surface and block slag, keeping the molten steel clean for pouring.

Usage Method of Slag-Blocking Wool

During pouring, it forms an insurmountable slag-blocking, slag-filtering, and slag-collecting barrier at the ladle opening, without adhering to the ladle wall. It provides excellent heat insulation, heat preservation, light blocking, and radiation protection. It effectively ensures the purity of the poured molten steel and the safety of the pouring process. After pouring, it can be easily removed.
