一种铁钩用浇注料及研制方法(国外英文资料)Read the bookThe wood invention is involved in a kind of iron ore blast furnace to make the castings and the preparation methods, which belong to the field of refractory materials technology. The castable with corundum powder, SiC powder, alumina powder, high temperature asphalt cement or calcium aluminate cement, a one Ale 0: ultra-fine powder, Si02 ultrafine powder, silicon metal powder as the main raw material, sodium tripolyphosphate or sodium hexametaphosphate and metal aluminium powder as additive, adding alumina powder coal ash for the blast furnace iron groove after mixing with refractory castable. The castable in plus 3} when using 7% of the water after mixing into the tapping ditch casting mould, through a vibrator or the castable vibrating plate under vibration, the natural hardening after drying and demoulding again after 80 c to 700 c water after drying and heat treatment to eliminate castable. Castable has excellent resistance to blast furnace described strong performance and the use of performance, can effectively reduce the tapping ditch with refractory castable into wood, at the same time has opened up a new application of alumina powder coal ash comprehensive utilization way.The characteristics of a cast-iron cast-iron cast-resistance material is that the pouring material is made of industrial grade alumina powder and SiC powderMaterials, high temperature asphalt powder, alumina cement or calcium aluminate cement, a a11203 ultra fine powder, Si02 superfine powder, metal silicon powderThe main raw materials are sodium tripolyphosphate or sodium hexanaphosphate as dispersant, with metal aluminum powder as additive, and a proper amount of explosion-proofOrganic fibers and high alumina coal ash; Described industrial-grade corundum powder according to 10 ^ 90% mass fraction of total ingredients; Silicon carbide powderAccording to the total mass fraction of ingredients ^ 5-35%; The high temperature asphalt is equal to 0.3-} -8% of th
