Ceramic side sealing plate for double-roller thin-strip continuous casting and preparation method of ceramic side sealing plate
The invention belongs to the technical field of double-roller thin-strip continuous casting, and particularly relates to a ceramic side sealing plate for double-roller thin-strip continuous casting. The ceramic side sealing plate comprises a base plate, a reinforcing plate and a sintering aid, through holes are formed in the base plate and the reinforcing plate, the positions of the through holes correspond to each other, the base plate is prepared from the following raw materials: BN-ZrO2, zirconium carbide and silicon carbide, and the reinforcing plate is prepared from the following raw materials: two-dimensional hexagonal boron nitride, oxide and nitride. The base plate has low heat conductivity and good thermal shock resistance and corrosion resistance, the reinforcing plate has good thermal shock resistance, wear resistance and corrosion resistance, the base plate and the reinforcing plate take AlN as a sintering aid, and the base plate and the reinforcing plate are subjected to hot pressed sintering, so that the ceramic side sealing plate is obtained, the overall performance of the side sealing plate is better, and the service life of the side sealing plate is longer. The through holes are formed in the base plate and the reinforcing plate, the sintering aid is added between the base plate and the reinforcing plate and in the through holes, and it can be guaranteed that the overall structure between the base plate and the reinforcing plate is more stable.
本发明公开的属于双辊薄带连铸技术领域，具体为一种双辊薄带连铸用陶瓷侧封板，包括基板、加强板与烧结助剂，所述基板与加强板上均开设有通孔，且通孔的位置相对应，所述基板由以下原料制成：BN‑ZrO2、碳化锆与碳化硅，所述加强板由以下原料制成：二维六方氮化硼、氧化物与氮化物，本发明基板具有低热导率，良好的抗热震性能与抗腐蚀性能，加强板具有良好的抗热震性能、耐磨损性能与抗腐蚀性能，基板与加强板通过AlN作为烧结助剂，两者进行热压烧结，得到陶瓷侧封板，使得侧封板的整体性能更好，使用寿命更长，通过在基板与加强板上开设有通孔，并通过在基板与加强板之间、通孔内加入烧结助剂，能够保证了基板与加强板之间整体结构更加稳定。
