STEEL-POURING REFRACTORY MATERIAL

摘要

The invention relates to the refractory industry, namely to the composition of steel-pouring refractory material. The steel-pouring refractory material contains mullite-corundum with the content of АlОmore than 72 weight %, graphite, aluminium-containing component and as binder - phenol-formaldehyde resin. Also it can additionally contain magnesian component. The invention provides the increasing of strength and stability, decreasing of open porosity of products, produced from the stated composition, and can be used in steel pouring.
