Abstract
The invention relates to a long-service-life repair-free unfired ceramic wear-resistant material for a blast furnace cinder flushing groove and an application method thereof, which belongs to the field of refractory materials and is mainly used for a blast furnace cinder flushing groove lining. The ceramic wear-resistant material is mainly prepared from 45-60% of wear-resistant aggregate (high-aluminum homogenized material and bauxite chamotte), 0.5-1.5% of naphthalene water reducer, 10-30% of Portland cement 42.5, 10-30% of pure calcium aluminate cement, 5-10% of ultramicropowder, 5-10% of metallic iron and 1-5% of stainless steel fiber. The ceramic wear-resistant material is usable immediately after uniformly mixing the raw materials at room temperature. The product has the advantages of no need of firing and high binding property, can have the service life of more than 5 years when being used for a blast furnace cinder flushing groove lining, does not need repair in the service period, and prolongs the service life of the cinder flushing groove.
Description
Technical field
The invention belongs to fire resisting material field, relate to a kind of blast furnace slag flushing groove ceramic wear-resisting material, be mainly used in blast furnace slag flushing groove liner.
Background technology
The conventional liner of blast furnace slag flushing groove is cast steel matter and silicon carbide, silicon nitride material, and traditional cast steel cell life is about 2 years, and work-ing life is shorter.Although silicon carbide, silicon nitride cinder-flushing groove liner have improved work-ing life, need irregular repairing to safeguard, and material require burn till and could obtain sufficient intensity, production and installation are comparatively loaded down with trivial details.
Summary of the invention
The invention provides the unburned blast furnace slag flushing groove ceramic wear-resisting material of a kind of longevity, can reach more than 5 years work-ing life, and in use, without repairing, effectively raise the work-ing life of blast furnace slag flushing groove.
The present invention is achieved through the following technical solutions, product main raw material is abrasive aggregates (high alumina homogenization material, bauxite chamotte) 45 ~ 60%, naphthalene water reducer 0.5 ~ 1.5%, normal silicate 42.5 cement 10 ~ 30%, pure calcium aluminate cement 10 ~ 30%, super-fine powder 5 ~ 10%, metal iron powder 5 ~ 10%, Stainless Steel Fibre 1 ~ 5%.By above-mentioned powder proportioning, under the condition of room temperature, mix and can obtain this product.
Abrasive aggregates grain size distribution (3 ~ 5 mm): (3 ~ 1 mm): (< 1 mm)=1:1:1.
invention feature
Traditional ceramics wear-resistant material is as silicon carbide, silicon nitride material, and its raw materials cost is higher, and need of production at high temperature burns till, and in use needs irregular repair maintenance, to increase the service life.
The ceramic wear-resisting material that the present invention produces, compares with traditional ceramic wear-resisting material, and raw material is more cheap and easily obtain, raw material mixes and can use under the condition of room temperature, without burning till, convenient storage and construction, long service life and during use without repairing.This is because the ceramic wear-resisting material that the present invention produces, used cement material, viscosifying power is strong, the own hydraulicity of cement makes material can obtain enough intensity at normal temperature, and later strength also can slowly increase, therefore, the wear-resistant material that the present invention produces has unburned, mixes at ambient temperature the i.e. feature of use.The fe adding in raw material, when warm sludge flows through, expanded by heating, make material when high temperature, not produce cracking, and fe add the wear resistance that has strengthened material monolithic, improved work-ing life, therefore, the wear-resistant material that the present invention produces has during use without repairing, and long feature of life-span.
