Abstract
The invention discloses a high-temperature wear-resistant composite material prepared from the following raw materials in parts by weight: 32 parts of high-alumina materials, 20 parts of sintered mullite, 28 parts of green silicon carbide, 6 parts of alumina micropowder, 4 parts of silica micropowder, 6 parts of fireproof cement, 4 parts of aquamarine powder, 4 parts of stainless steel fiber, 0.1 part of SM (Styrene Monomer) and 0.1 part of sodium hexametaphosphate. The composite material of the invention has the advantages of high fireproof degree and bonding strength, stable volume, good high-temperature strength and wear-resistant preservative effect, wide scope of application, and the like, can be used for casting or coating a guiding gutter of a sintering machine, a blast furnace grain slag ditch, a cyclone dust pipeline for a blast furnace, and the like, such as used for casting the guiding gutter of the sintering machine, the service life of the guiding gutter of the sintering machine is prolonged to 10 months in a working environment of 800-1000 DEG C, the maintenance cycle is greatly prolonged and the production cost of smelting enterprises is decreased.
Description
Technical field
The present invention relates to the matrix material that a kind of field of metallurgy is used, especially relate to a kind of field of metallurgy sinter machine diversion trench, high-temperature wearable matrix material of blast furnace granulated slag ditch, tuyere zone, flue etc. of being used for.
Background technology
In the smelting process of iron and steel enterprise, many equipment all will be worked in hot environment continuously, cause the equipment concentrated wear more serious, have influenced the ordinary production of iron and steel enterprise.Like diversion trench about the pellet sinter machine; Tradition adopts heat-resisting alloy steel to process, owing to be in continuously in 800-1100 ℃ the hot environment, is hot melt to the medium-soft state; Diversion trench about 10 square metres will bear nearly 3 meters of up to ten thousand tons of drops every day, piece weighs the impact that does not wait the high temperature sintering material of weight about tens kilograms to three tons and average area is merely; Only have 30-45 days normal work-ing life, seriously restricted the works better of sinter machine, influenced the output of sintered material; Just like positions such as blast-furnace tuyere, flue, tornado dust collector, blast furnace granulated slag ditches, also need possess the refractory materials of high temperature resistant, shock-resistant performance again, to prolong the work-ing life of aforesaid device.And existing traditional refractory materials is high temperature resistant passable, but rub resistance and toughness impact resistance are relatively poor.
Summary of the invention
The object of the present invention is to provide intensity and all good, the applied widely high-temperature wearable matrix material of toughness in a kind of refractoriness height, volume stability, the hot environment.
For realizing above-mentioned purpose, the present invention can take following technical proposals:
High-temperature wearable matrix material of the present invention; It is to be prepared from according to the following weight parts proportioning by raw material high aluminium material, fused mullite, green silicon carbide, alumina powder, silicon powder, refractory cements, aquamaine stone flour, Stainless Steel Fibre and SM (water reducer, market is on sale), Sodium hexametaphosphate 99:
