Liner - for distribution shiyu - to

摘要

(57) Abstract Objective This device to lie between the hopper and the blast furnace, hotsuThe per empty distributing the iron ore and the corks which are supplied inside the blast furnaceIn order to raise the abrasion resistance of the distribution chute which it does distribution chuteBeing the liner which is administered to the surface, being superior to abrasion resistance,As use life of distribution chute can be made long, chip resistanceTo be superior, cracking and being lacking etc to be difficult to occur, distribution chuteStabilizing use life, can being able principal objectWith it does. Constitution To lie between the hopper and the blast furnace, from the hopper offering/accompanyingIron ore which is provided and distribution shi which distributes the corks inside the blast furnaceThe abrasion-resistant it is administered to that surface in order to raise the abrasion resistance of yutoRegarding to the liner for distribution chute which consists of the Characteristic material, description aboveAs for the liner for distribution chute, in the board which consists of the iron based metal sinteringThe board which consists of the cemented carbide, lying between the low material between, directlyForming in one body with electric modulo, with the composite material which can the unit resistanceThe worn material is formed, multiple of the above-mentioned unit abrasion proof material is spread densely, averageIt is formed due to be ru thing, consists of the above-mentioned sintering cemented carbideThe board inside to face in the inside of distribution chute layingIt features that the re te it is.
