Bloom continuous casting tundish cover castable and construction method thereof
The invention discloses a large square billet continuous casting tundish cover castable and a construction method thereof. The large square billet continuous casting tundish cover castable is prepared from the following raw materials in parts by weight: 70-85 parts of coal gangue calcined kaolin, 8-15 parts of calcined alumina powder, 5-9 parts of high-alumina cement and 2-6 parts of ball clay. And 0.2 to 0.5 part of an additional water reducing agent. The tundish cover castable disclosed by the invention has the comprehensive excellent properties of high strength, good thermal shock resistance and proper thermal insulation property. The ladle cover of the large square billet tundish has the functions of heat preservation, stable application structure, no pollution to molten steel and long service life.
本发明公开了一种大方坯连铸中间包包盖浇注料及其施工方法，包括总和为100重量份的下述原料：煤矸石煅烧高岭土70～85份，煅烧氧化铝粉8～15份，高铝水泥5～9份，球粘土2～6份；以及外加减水剂0.2～0.5份。本发明中间包包盖浇注料具有强度高、抗热震性好、保温性能合适的综合优异性能。能够满足大方坯中间包包盖兼顾保温、应用结构稳定，不污染钢水、长寿命的功能。
