High-temperature-resistant heat-preservation permanent lining for steel ladle
The invention discloses a high-temperature-resistant heat preservation permanent lining for a steel ladle. Raw materials comprise corundum, hollow spheres, fiber materials, aluminum oxide micro-powder, silicon oxide micro-powder, pure calcium aluminate cement and expansible raw materials. By adopting the high-temperature energy-saving steel ladle permanent lining, the problems that a steel ladle permanent lining is not resistant to high temperature and energy is wasted are solved, the fire resistance of the permanent lining material is improved, the material is endowed with low thermal conductivity due to good thermal insulation performance, the molten steel cooling amplitude is reduced, deformation of the steel shell is eradicated, the working lining can be replaced in a short time, the danger of steel ladle penetrating is reduced, equipment and personnel safety is guaranteed, meanwhile, the residual thickness of the working lining can be greatly reduced, the performance of the working lining is fully played, the use amount of the working lining and the lining repairing frequency are reduced, the service life of a steel ladle is prolonged, natural resources and energy are saved, and economic benefits are improved.
本发明公开了一种钢包用耐高温保温永久衬，原始料为刚玉、空心球、纤维类材料、氧化铝微粉、氧化硅微粉、纯铝酸钙水泥和膨胀性原料；本发明这种高温节能钢包永久衬，解决钢包永久衬不耐高温、浪费能源的问题，提高永久衬材料的耐火性能，良好的绝热性能赋予材料低热导率，减少钢水降温幅度，杜绝钢壳变形，可短时间代替工作衬，降低钢水穿包的危险，确保设备及人员安全，同时能使工作衬残存厚度大幅减少，充分发挥工作衬的性能，减少工作衬的使用量及修衬次数，延长钢包使用寿命，节约自然资源和能源，提高经济效益。
