Problems solved by technology

[0002] In the early days, the blast furnace tapping channel was generally made of clay clinker, coke grains, light clay and tar pitch. The amount of iron passing was small, the repair was frequent, the working conditions were poor, and the environment was polluted. In recent years, Al 2 o 3 -SiC-C ramming material and Al 2 o 3 -SiC-C castables, which are generally made of dense corundum, sub-white corundum, brown corundum, high-quality high-alumina clinker, silicon carbide and flake graphite plus various ultrafine p

Abstract

The invention discloses a method for producing a trough ramming material by recycling wastes with low cost. The invention employs the waste materials discharged by one or a plurality of steel factories to prepare a product by the steps of cracking, washing, airing, de-ironing, screening classification, finished product materials, and preparing. Compared with the manufacture materials of high energy consumption like the materials of compact corundum, sub-white corundum, excellent high alumina and carborundum used by the traditional trough ramming materials, the method has the advantages of reducing the product cost by more than 30 percent and having better use effect; moreover, the method saves resources and energies, reduces the environment pollution sources, and has excellent economic and social benefits.

Description

technical field [0001] The invention relates to a method for producing iron gutter ramming material. The iron gutter ramming material is made of one or more waste materials discharged from iron and steel production after recycling and preparation. The iron gutter ramming material belongs to iron and steel metallurgy The main refractory material in blast furnace tapping system. Background technique [0002] In the early days, the blast furnace tapping channel was generally made of clay clinker, coke grains, light clay and tar pitch. The amount of iron passing was small, the repair was frequent, the working conditions were poor, and the environment was polluted. In recent years, Al 2 o 3 -SiC-C ramming material and Al 2 o 3 -SiC-C castables, which are generally made of dense corundum, sub-white corundum, brown corundum, high-quality high-alumina clinker, silicon carbide and flake graphite plus various ultrafine powders, additives and binders. , the above materials are all ...
