Chromium-free seating brick for RH alloy trough and preparation method of chromium-free seating brick
The invention discloses a chromate-free seating brick for an RH alloy trough and a preparation method of the chromate-free seating brick, and the chromate-free seating brick for the RH alloy trough is formed by integrally pouring a corundum castable and an internal steel structure assembly, the corundum castable is prepared from the following raw materials in percentage by weight: 55 to 75 percent of tabular corundum, 10 to 35 percent of fused alumina zirconia, 6 to 12 percent of pure calcium aluminate cement, 6 to 12 percent of alpha alumina micro powder and 0.2 to 1 percent of water reducing agent. The RH alloy trough chromate-free seating brick prepared by the method can adapt to RH chromate-free, the toughness, strength and erosion resistance of the RH furnace alloy trough seating brick are greatly improved, the service life of the RH furnace alloy trough seating brick is prolonged, and patching of the alloy trough seating brick and peripheral wall bricks is reduced.
本发明公开一种RH合金料槽无铬化座砖及其制备方法，其中RH合金料槽无铬化座砖由刚玉质浇注料和内部钢结构组件整体浇筑形成，所述刚玉质浇注料的原料组成及重量百分比如下：板状刚玉55～75％、锆刚玉10～35％、纯铝酸钙水泥6‑12％、α氧化铝微粉6～12％、减水剂0.2～1％。通过本发明方法制备得到的RH合金料槽无铬化座砖能够适应于RH无铬化，大幅度提升RH炉合金料槽座砖的韧性、强度及抗冲毁能力，同时提高其使用寿命，减少了合金料槽座砖及四周壁砖的挖补。
