Plastic high-temperature ceramic sealing gasket for steel ladle sliding nozzle and preparation method of plastic high-temperature ceramic sealing gasket
The invention discloses a plastic high-temperature ceramic sealing gasket for a steel ladle sliding nozzle. The raw material formula of the ceramic sealing gasket consists of an outer-layer raw material and an inner-layer raw material, wherein the inner-layer raw material comprises the following raw components in parts by weight: aluminum oxide, magnesium oxide, magnesium aluminate spinel, silicon carbide, metal silicon, modified aluminum sol and an adhesive; and the outer-layer raw material is a graphite material. The ceramic sealing gasket has excellent plastic deformation performance, high-temperature use performance and processible performance, can generate irreversible plastic deformation to be filled between contact parts of a sliding plate and a sliding plate nozzle, and does not crack in the transportation and processing process; and a good combination body is formed between the sliding plate and the sliding plate nozzle under the local sintering action in the use process, so that the sealing performance is good, and the hidden danger of steel leakage at the part is solved.
本发明公开了一种钢包滑动水口用塑性高温陶瓷密封垫，陶瓷密封垫的原料配方由外层原料和内层原料组成；其中，所述内层原料包括如下重量份的组分：氧化铝、氧化镁、镁铝尖晶石、碳化硅、金属硅、改性铝溶胶、粘合剂；所述外层原料为石墨材料。其具备优异的塑性变形性能、高温使用性能和可加工性能，可发生不可逆的塑性变形填充在滑板和滑板水口的接触部位之间，在运输及加工过程中不会发生开裂，而且使用过程发生的局部烧结作用使其在滑板和滑板水口间形成非常好的结合体，具有很好的密封性能，解决了该部位产生漏钢的隐患等。
