Abstract
The invention discloses a pouring material for a sunk fence, which comprises, by weight, components of 70-85% of white corundum, 5-10% of calcium aluminate cement, 1-5% silica fume, 1-5% of alpha-A12O3, 1-5% of silicon carbide, 1-5% of heat resistant steel fiber, 1-5% of granule zircon, 0-0.5% of aluminate powder and 0-0.5% of sodium tripolyphosphate. The pouring material enables the white corundum to serve as aggregate and greatly strengthens abrasive resistance and high temperature resistance thermal change performance of the whole pouring material, the silicon carbide and the heat resistant steel fiber which serve as auxiliary materials are added to strengthen anti-skinning and mechanical stress resisting features of the pouring material, clinker can smoothly run on a grate bed, and service life is long.
Description
Technical field
The invention belongs to fire resisting material field, be specifically related to a kind of parapet with mould material and preparation method thereof.
Backgroundfield
Parapet mainly is positioned at two sections three sections positions of cooling machine.Because it is bigger to receive the thermal stresses effect of grog, very strong to the abrasion of parapet, grog is also bigger to the chemical erosion of the sulphur alkali salt at parapet position, and the mould material at this position needs higher wear resistance and high temperature resistant and acid resistance.Use the porzite flame-proof mould material in this field at present, shortcoming is that wear resistance is relatively poor, and work-ing life is shorter, a little less than the hot abrasion and chemical erosion effect to the high temperature chamotte generation.
Summary of the invention
Goal of the invention: the objective of the invention is to deficiency, provide a kind of parapet to use mould material to prior art.
Another object of the present invention is to provide the preparation method of above-mentioned mould material.
Technical scheme: in order to reach goal of the invention; The present invention specifically realizes like this: a kind of parapet is used mould material, comprises following components in weight percentage: 70～85% white fused alumina, 5～10% aluminous cement, 1～5% SILICA FUME, α-Al of 1～5%
2O
3, 1～5% silit, 1～5% heat-resistant steel fiber, 1～5% zirconium English powder, 0～0.05% aluminium powder and 0～0.5% tripoly phosphate sodium STPP.
Wherein, the fineness of said white fused alumina is less than 15mm.
Wherein, the fineness of said silicon powder is less than 2000 orders.
Wherein, said α-Al
2O
3Fineness be 500～800 orders.
Wherein, the fineness of said zirconium English powder is less than 300 orders.
Wherein, the fineness of said aluminium powder is less than 300 orders.
Prepare the method for above-mentioned parapet, may further comprise the steps with mould material:
(1) measures white fused alumina, SILICA FUME, α-Al by prescription
2O
3, silit, heat-resistant steel fiber, zirconium English powder and aluminium powder, fragmentation;
(2) above-mentioned raw materials is mixed 8～10 minutes after, the aluminous cement and the tripoly phosphate sodium STPP that add formula ratio also stirred 4～6 minutes;
(3) in the mixture of step (2), add the water of mixture total mass 5～10%, stir and promptly got in 5～8 minutes.
Beneficial effect: the present invention uses white fused alumina to be aggregate; Having strengthened whole wear resistance and the high temperature heat-resistant sex change of mould material greatly can; Adding silit and heat-resistant steel fiber is the characteristic that auxiliary material strengthens its resistive connection skin and anti-mechanical stress; Make grog more smooth and easy, longer service life at the comb bed operating.
