Abstract
PURPOSE: To increase remarkably the ratio of effective use of furnace material, by constituting the lining described in the title of an inner lining material made of castable refractory resistant to molten cast iron and a backing material made of castable refractory having resistance to embrittlement and a prescribed strength even in heat treatment at a specific temp.
CONSTITUTION: In lining structure of a blast furnace spout, a castable refractory material resistant to embrittlement having ≥400kg/cm2 compression strength even in heat treatment at 300W1,000°C temp. is used as the castable backing material for the inner side of the blast furnace spout, and as the inner lining material for said backing material is used a castable refrctory material having resistance to molten cast iron and to spalling so as to constitute double layered coating structure. This structure makes possible additional repairment for a long time, hence the ratio of effective use of the refractory material is increased remarkably.
