Low-cost continuous casting tundish slag blocking wall
The invention relates to a low-cost continuous casting tundish slag stopping wall which comprises a slag stopping wall peripheral part, and a slag stopping wall core part which is integrally formed by casting is arranged in the center of the slag stopping wall peripheral part. The castable at the periphery of the slag blocking wall comprises the following raw materials in parts by weight: 30-60 parts of magnesia with the particle size of 3-5mm, 50-90 parts of magnesia with the particle size of 1-3mm, 30-60 parts of magnesia with the particle size of 0-1mm, 10-20 parts of corundum with the particle size of 0.1-1mm, 1-3 parts of silica micropowder with the particle size of 200 meshes, 2-5 parts of a resin binder and 0.2-1 part of silica sol. The pouring material of the slag stopping wall core part is prepared from the following raw materials in parts by weight: 30 to 50 parts of waste magnesia carbon brick particles with the particle size of 3 to 5mm, 80 to 110 parts of waste magnesia carbon brick particles with the particle size of 1 to 3mm, 30 to 50 parts of waste magnesia carbon brick particles with the particle size of 0 to 1mm, 10 to 20 parts of corundum with the particle size of 0.1 to 1mm, 1 to 3 parts of silicon dioxide micro powder with the particle size of 200 meshes, 2 to 5 parts of resin binder and 0.2 to 1 part of silica sol. One side of the periphery of the slag stopping wall serves as a steel facing face, and the slag stopping wall is made of new materials and is excellent in high-temperature performance. And one side of the core part of the slag stopping wall serves as a non-steel-facing surface and is basically prepared from a waste refractory material, so that the production cost is reduced while the strength of the slag stopping wall is met.
本发明涉及一种低成本连铸中间包挡渣墙，包括挡渣墙外周部，挡渣墙外周部的中心设有一体浇注成型的挡渣墙芯部。所述的挡渣墙外周部的浇注料，原料按重量份包括镁砂3‑5mm，30‑60份，镁砂1‑3mm，50‑90份，镁砂0‑1mm，30‑60份，刚玉0.1‑1mm，10‑20份，二氧化硅微粉200目，1‑3份，树脂结合剂2‑5份，硅溶胶0.2‑1份。所述的挡渣墙芯部的浇注料，原料按重量份包括废镁碳砖颗粒3‑5mm，30‑50份，废镁碳砖颗粒1‑3mm，80‑110份，废镁碳砖颗粒0‑1mm，30‑50份，刚玉0.1‑1mm，10‑20份，二氧化硅微粉200目，1‑3份，树脂结合剂2‑5份，硅溶胶0.2‑1份。本申请挡渣墙外周部一侧作为迎钢面，采用新材料制备，高温性能优越。挡渣墙芯部一侧作为非迎钢面，基本采用废耐火材料制备，在满足挡渣墙强度的同时降低生产成本。
