Abstract
The invention relates to a tundish nozzle seat brick filling material prepared by employing waste high-alumina bricks and waste magnesite bricks, wherein the raw materials (by weight portions) of the filling material include waste high-alumina bricks 55-90 parts, waste magnesite bricks 5-30 parts, and workability providing agent 3-15 parts including alta-mud or mild-clay. The invention realizes environmental protection and low cost.
Description
Technical field
The present invention relates to tundish nozzle pocket stopping composition in the ferrous metallurgy continuous casting.
Background technology
The continuous casting ratio of China's ferrous metallurgy has reached more than 95% at present, middle bag more and more causes people's generally attention as last link of metallurgical industry, and the useless used stopping composition of brick of middle water-coating port, up to this point still adopt magnesium chromium matter ramming mass, or corundum pouring material.Magnesium chromium matter ramming mass cost is higher, also has the chromium ion pollution problem, and the corundum pouring material cost is higher, requires also harsher to baking; Also there is use alumina matter ramming mass in the advanced developed country of minority, and result of use is good after the import, but price is still very high, and supplies untimely.
The applicant Zhongxing Mining Group Co., Ltd., Liaoning Industrial Stoves are more, the depleted high alumina brick is sufficient with burning magnesia brick source after repairing kiln, and according to the Working environment and the working conditions of middle back stall brick, we think that the depleted high alumina brick is very high with burning magnesia brick refractoriness, the high temperature requirement of bag in satisfying
Summary of the invention
The purpose of this invention is to provide a kind of depleted high alumina brick and burning magnesia brick is tundish nozzle pocket stopping composition during main raw material is made, and this method is utilized MgO-Al
2O
3The Ke Kendaer response effect of two component system two ends unit component adds an amount of workability imparting agent, and control material has the expansion reaction of appropriateness, security and the reliability of Bao Genggao in giving.
For achieving the above object, the present invention adopts following technical scheme to realize:
Utilize tundish nozzle pocket stopping composition in the making of useless high alumina brick and useless magnesia brick, it is characterized in that this stopping composition is to be made by the following raw materials in parts by weight ratio: useless high alumina brick 55-90 part, useless magnesia brick 5-30 part, workability imparting agent 3-15 part;
Described workability imparting agent is meant wilkinite or soft clay;
The technical process of tundish nozzle pocket stopping composition was during useless high alumina brick of described utilization and useless magnesia brick were made: at first with raw material high alumina brick and useless magnesia brick fragmentation, screening, mix in described weight part ratio, add the workability imparting agent according to described weight part ratio again, mixing and stirring, pack goes out finished product.
The finished product technical performance index:
Chemical ingredients/% MgO 50～80
