Castable for tapping channel of steelmaking electric furnace and preparation method thereof
The invention relates to the technical field of tapping channel castables of steelmaking electric furnaces. The invention further discloses a castable for a tapping channel of a steelmaking electric furnace and a preparation method of the castable. The castable is prepared from the following raw materials in parts by weight: 60 to 72 parts of special-grade alumina clinker particles, 5 to 20 partsof andalusite powder, 5 to 10 parts of silicon carbide powder, 3 to 10 parts of alpha-alumina powder, 5 to 10 parts of graphite micro powder, 4 to 8 parts of silica powder, 4 to 10 parts of aluminatecement, 2 to 10 parts of an antioxidant and 0.1 to 0.5 part of a dispersing agent. The invention discloses the castable for the tapping channel of the steelmaking electric furnace and the preparationmethod thereof. The special-grade high-alumina bauxite clinker as a main raw material has the characteristics of compact structure, good high-temperature volume stability and high refractoriness, great convenience is provided for manufacturing the castable of the tapping channel, the content of silicon in silicon carbide is set to be greater than 90% by adding a proper amount of silicon carbide and carbonaceous materials, and the cutting hardness is further increased due to good thermal conductivity and strong cutting capacity of the silicon carbide.
本发明涉及炼钢电炉的出钢槽浇注料技术领域，且公开了一种用于炼钢电炉出钢槽的浇注料及其制备方法，包括以下重量份数配比的原料：特级矾土熟料颗粒60‑72份、红柱石粉5‑20份、碳化硅粉5‑10份、α‑氧化铝粉3‑10份、石墨微粉5‑10份、硅微粉4‑8份、铝酸盐水泥4‑10份、抗氧化剂2‑10份、分散剂0.1‑0.5份。该用于炼钢电炉出钢槽的浇注料及其制备方法，通过将特级高铝矾土熟料作为主要原料，其具备结构致密、高温体积稳定性好、耐火度高的特点，为制造出钢槽的浇注料提供了极大的便利，通过配入有适量的碳化硅、碳质材料，将碳化硅中硅的含量设置为大于百分之九十，由于碳化硅导热性好，且切削能力强，进一步增大了切削硬度。
