Method for producing iron runner ramming mass by recovering steel plant waste

Abstract

The invention discloses a method for producing an iron runner ramming mass by recovering waste materials of an iron and steel plant. One or more waste materials used and discharged by the iron and steel plant are utilized and subject to crushing, water washing, sun drying, iron removal, sieve classification, obtaining raw materials of a finished product and preparation to obtain the finished product. Compared with high-energy consumption manufacturing raw materials such as dense corundum, sub-white corundum, good-quality high aluminum clinker, silicon carbide and the like used in the traditional iron runner ramming mass, the iron runner ramming mass has the advantages of reducing more than 30% of product cost, better application effect, saving resources and energy resources, reducing environmental pollution sources, and having very good economic benefit and social benefit.

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 ...

[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 resource materials, which consume a lot of energy in the manufacturing process and the equipment investment costs are large. In addition, the current material scheme is not only expensive for the iron trench material products, but also because the waste materials in the iron and steel production plant cannot be processed in a timely and effective manner. Make full use of it, objectively there is also the actual situation of increasing environmental pollution
