BBL-2 Molai stone fire-resistant molding material

BL-2 Molai stone fire-resistant molding material is a kind of unshapely fire-resistant material that is adopted capacitive Molai stone as essential substance and compounded with super-tiny mote, additive and fibre of stainless steel. It is mainly used in pretreatment injector of steel-making molten iron, molding in containor of mixing iron at the mouth of furnace, obstructing residue machine. Its average life-span reaches the criterion of DLCIAZ5 material Heiqi Japan, which was proved by the application in Baoshan Steel Plant. The product was passed provincial authentication on Aug 1992 and acquired technology development award in the same year.
