Description

High-strength steel fibre castable
Technical field
The present invention relates to the cement kiln mould material, especially relate to the high-strength steel fibre castable of low, the alternative corundum matter of a kind of cost.
Background technology
In kilns such as cement kiln outlet, preheater, cooling machine, tradition adopts corundum matter high-strength castable, because corundum material cost height, the raw materials cost of enterprise is just high.
Summary of the invention
The object of the present invention is to provide that a kind of cost is low, the high-strength steel fibre castable of alternative corundum pouring material.
For achieving the above object, the present invention can take following technical proposals:
High-strength steel fibre castable of the present invention, it is formulated according to following weight parts by bauxite raw material, brown corundum, alumina powder, silicon carbide, silicon powder, CA-70 cement, No. 446 heat-resistant steel fibers, explosion-proof steel fiber and tripoly phosphate sodium STPPs, Sodium hexametaphosphate 99:
2.5 parts in granularity 8-5mm bauxitic clay material, 0.075mm 2.3 parts of＜granularities＜5mm bauxitic clay material, 2 parts in granularity 3-1mm palm fibre corundum in granules material, 0.8 part of granularity≤0.075mm bauxitic clay material, 0.4 part of granularity≤0.025mm aluminum oxide super-fine powder, 0.6 part of granularity≤0.075mm sic powder, 0.3 part of granularity＜0.019mm silicon powder, 0.6 part of CA-70 cement, 0.5 part of granularity＜0.053mm brown alundum powder material, 0.2 part of No. 446 heat-resistant steel fiber, 0.02 part of explosion-proof steel fiber, the tripoly phosphate sodium STPP of total weight of material 0.1%, the Sodium hexametaphosphate 99 of total weight of material 0.08%.
The standard of described bauxitic clay is Al 2O 3〉=80%, Fe 2O 3＜1.5%.
The standard of described brown corundum is Al 2O 3〉=97%, Fe 2O 3＜0.30%.
The standard of described silicon carbide is SiC 〉=97%, Fe 2O 3≤ 1%.
The standard of described silicon powder is SiO 2〉=97%.
The standard of described CA70 cement is Al 2O 3〉=69%.
The standard of described aluminum oxide powder is Al 2O 3〉=99%.
The invention has the advantages that the compressive strength height, the folding strength height, the refractoriness under load height, the anti-thermal shock good stability, the characteristic that at high temperature has microdilatancy, advantages such as wear resisting property is good, though alumina content decreases with respect to traditional high-strength castable, but because the cement consumption of this product reduces greatly, calcium oxide content is wherein reduced greatly, wherein the silicon carbide of admixture can play when middle temperature and gain in strength, strengthen creep property, improve the effect of refractoriness and remedied the not high shortcoming of alumina content, with respect to traditional high-strength castable, have higher compressive strength and folding strength, because adopted alumine to replace part corundum material in traditional high-strength castable, the comparable traditional high-strength castable of cost reduces about 2/5, reduced the consumption that produces because of raw materials for production indirectly, also increased work-ing life simultaneously than traditional high-strength castable.But this product widespread use and cement kiln outlet, preheater, cooling machine etc. are the desirable product innovations that substitutes the ordinary steel fibre castable to requirement of strength height, other abominable kiln of working conditions.This product physical and chemical index and the contrast of traditional mould material see the following form:
