Magnesium-aluminum dry material for continuous casting tundish
The invention relates to the technical field of refractory materials, in particular to a magnesium-aluminum dry material for a continuous casting tundish, and aims to solve the problems of short service life of the tundish, high consumption of the refractory materials, pollution to molten steel caused by erosion of the refractory materials, high energy consumption in a steelmaking process, low permeability resistance and low scouring resistance and the like in the prior art. Comprising the following components in parts by mass: 40-90 parts of magnesia, 3-40 parts of bauxite clinker, 3-30 parts of corundum and 0.2-2 parts of titanium dioxide. The magnesium-aluminum dry material is used for the continuous casting tundish working lining, the service life of the continuous casting tundish working lining can be prolonged, pollution to molten steel caused by erosion of a refractory material is reduced, energy consumption in the steelmaking process is reduced, and the defects that a traditional magnesium dry material is poor in permeability resistance and scouring resistance are overcome. The concrete has the characteristics of good permeability resistance and erosion resistance, and has good economic benefits and environmental benefits for iron and steel enterprises and refractory material enterprises.
本发明涉及耐火材料技术领域，尤其涉及一种连铸中间包用镁铝质干式料，针对现有技术中间包使用寿命短，耐火材料消耗量大，耐火材料侵蚀对钢水造成的污染，炼钢过程中的能源消耗大，抗渗透性和抗冲刷性低等问题，现提出如下方案，包括如下质量份数的组份组成：镁砂40‑90份，铝矾土熟料3‑40份，刚玉3‑30份，钛白粉0.2‑2份；本发明的目的是镁铝干式料用于连铸中间包工作衬，可延长连铸中间包工作衬使用寿命，减少耐火材料侵蚀对钢水造成的污染，降低炼钢过程中的能源消耗，克服了传统镁质干式料抗渗透性和抗冲刷性能差的缺点，具有抗渗透性、抗冲刷性好的特点，对钢铁企业和耐火材料企业均具有良好的经济效益和环境效益。
