Continuous casting tundish magnesia-calcium dry vibrating material and preparation method thereof
The invention relates to a continuous casting tundish magnesia-calcium dry vibrating material. The material comprises the following components in parts by weight: 10-15% of magnesia-calcium-carbon waste bricks with the granularity of more than 3 and less than or equal to 5mm, 10-15% of magnesia-calcium-carbon waste bricks with the granularity of more than 1 and less than or equal to 3mm, 15-20% of magnesia-calcium-carbon waste bricks with the granularity of more than 0 and less than or equal to 1mm, 0-5% of 91 magnesia with the granularity of more than 3 and less than or equal to 5mm, 10-20% of 91 magnesia with the granularity of more than 1 and less than or equal to 3mm, 10-25% of 95 medium-grade magnesia with the granularity of more than 0 and less than or equal to 1mm, 25%-28% of 200-mesh 95 medium-grade magnesia, 2%-4% of a binding agent and 1%-2% of red clay. The dry vibration material is produced by using the waste magnesia-calcium-carbon bricks instead of magnesia as a raw material, and the use effect of the dry vibration material is basically the same as that of a dry vibration material prepared by using magnesia as a main raw material. The dry vibration material contains CaO, so that a molten steel purification effect is achieved, the slag resistance of the dry vibration material is improved, and the anti-scouring capacity of the dry vibration material is improved. The cost is effectively reduced, and the environmental pollution is reduced.
本发明涉及一种连铸中间包镁钙质干式振动料，按重量份包括：3＜粒度≤5mm的镁钙碳废砖10％‑15％，1＜粒度≤3mm的镁钙碳废砖10％‑15％，0＜粒度≤1mm的镁钙碳废砖15％‑20％，3＜粒度≤5mm的91镁砂0％‑5％，1＜粒度≤3mm的91镁砂10％‑20％，0＜粒度≤1mm的95中档镁砂10％‑25％,200目的95中档镁砂25％‑28％，结合剂2％‑4％，红黏土1％‑2％。本发明以废镁钙碳砖替代镁砂作为原料生产干式振动料，使用效果与以镁砂为主要原料制作的干式振动料基本相同。含有CaO起到净化钢水作用，提高其抗渣能力，提高抗冲刷能力。有效地降低成本，减少环境的污染。
