Description
Technical field
The present invention relates to technical field of refractory castable, especially relate to the Novel steel fiber mould material of low, the alternative corundum of a kind of cost.
Background technology
In the kilns such as cement kiln outlet, preheater, grate-cooler, tradition adopts corundum high-strength castable, and because corundum material cost is high, the raw materials cost of enterprise is just high.
Summary of the invention
The object of the present invention is to provide the Novel steel fiber refractory castable of low, the alternative corundum pouring material of a kind of cost.
For achieving the above object, the present invention can take following technical proposals:
A kind of low cost new steel fiber refractories of the present invention is by raw material alumine, Brown Alundum, aluminum oxide super-fine powder, SiC fine powder, SiO
2micro mist, pure calcium aluminate cement, zircon sand, heat-resistant steel fiber, explosion-proof steel fiber and tripoly phosphate sodium STPP, Sodium hexametaphosphate 99 are formulated according to following weight parts:
Granularity 8-5mm alumine 2.3 parts, 0.075mm< granularity <5mm alumine 2.5 parts, granularity≤0.075mm alumine 0.7 part, granularity 3-1mm Brown Alundum particulate material 1.5 parts, granularity≤0.025mm aluminum oxide super-fine powder 0.5 part, granularity≤0.075mmSiC fine powder 0.8 part, granularity <0.019mmSiO
2micro mist 0.4 part, pure calcium aluminate cement 0.7 part, granularity <0.053mm zircon sand 0.5 part, heat-resistant steel fiber 0.3 part, explosion-proof steel fiber 0.04 part, the tripoly phosphate sodium STPP of total weight of material 0.1%, the Sodium hexametaphosphate 99 of total weight of material 0.06%.
