Abstract
The invention relates to a special nonstick aluminium wear-resistance castable which is prepared by putting the following raw materials: 30 % of mullite of 1 to 3 mm, 20 % of brown fused alumina, 5 to 20 % of silicon carbide of less than 0.088 mm, 20 % of alpha-alumina of less than 0.02 mm, 4 % of SiO2 powder, 3 % of sodium tripolyphosphate and 10 % of Guangxi white clay into a sand mixer, adding proper amount of water and stirring for 20 minutes.
Description
Affiliated technical field
The present invention relates to a kind of aspect metallurgical, employed mould material in building molten aluminium stove process, it can obviously improve the work-ing life of molten aluminium stove.
Background technology
At present, employed mould material in building molten aluminium stove process exists the anti-thermal shock poor stability, the shortcoming that resistance to fouling is poor, and easy and aluminium element generation chemical reaction, the yield rate of reduction product, the work-ing life of minimizing stove.
Summary of the invention
For overcoming in the existing situation, employed mould material in building molten aluminium stove process exists the anti-thermal shock poor stability, the shortcoming that resistance to fouling is poor, and easy and aluminium element generation chemical reaction, reduce the yield rate of product, the deficiency that reduces the work-ing life of stove the invention provides the not sticking aluminium wear-resistant castable of a kind of special type, the anti-thermal shock good stability of this mould material, be not easy to react with aluminium element, can effectively stop the infiltration of molten aluminium, prolong the work-ing life of stove.
The technical solution adopted for the present invention to solve the technical problems is: this scheme is divided following step,
1. main raw material preparation
13mm mullite 30%, brown corundum 20%,＜0.088mm silicon carbide 5-20%＜0.020mm α-aluminum oxide 20%, SiO2 powder 4%, tripoly phosphate sodium STPP 3%,, Guangxi white clay 10%
2. batch mixing
Above-mentioned raw materials is put into sand mill, add again an amount of water, stir and got final product in 20 minutes.
The invention has the beneficial effects as follows, can prolong the work-ing life of stove, effectively prevent the generation of molten aluminium Seepage.
