Multi-layer composite side sealing plate for double-roller thin-strip continuous casting and preparation method of multi-layer composite side sealing plate
The invention belongs to the technical field of refractory materials, and particularly relates to a multi-layer composite side sealing plate and a preparation method thereof, and the multi-layer composite side sealing plate comprises a working layer, a body, a heat preservation layer and an interlayer transition layer; the working layer is prepared from the following raw materials: BN, ZrO2, Al2O3, SiC and a sintering aid, the body is prepared from the following raw materials: BN, ZrO2 and SiC, the thermal insulation layer is prepared from the following raw materials: BN, hollow spheres, Al2O3, SiC, MgO and Si3N4, the transition layer between the working layer and the body is formed by mixing a working layer raw material and a body raw material, and the transition layer between the body and the thermal insulation layer is formed by mixing a body raw material and a thermal insulation layer powder raw material. The working layer has good abrasion resistance and molten steel erosion resistance, the body has good thermal shock resistance, the heat preservation layer has low heat conductivity, the working layer, the body and the heat preservation layer are subjected to hot pressing sintering, the transition layers are arranged between the working layer, the body and the heat preservation layer so that the working layer, the body and the heat preservation layer can be combined better, and the obtained multi-layer composite side sealing plate is better in overall performance and longer in service life.
本发明属于耐火材料技术领域，具体涉及一种多层复合侧封板及其制备方法，涉及的多层复合侧封板包括工作层、本体、保温层和层间过渡层；工作层由以下原料制成：BN、ZrO2、Al2O3、SiC和烧结助剂，本体由以下原料制成：BN、ZrO2和SiC，所述保温层由以下原料制成：BN、空心球、Al2O3、SiC、MgO和Si3N4，工作层和本体之间的过渡层由工作层原料和本体原料混合组成，本体和保温层之间的过渡层由本体原料和保温层粉末原料混合组成。本发明工作层具有良好的耐磨性和抗钢液侵蚀性，本体具有良好的抗热震性，保温层具有低的热导率，工作层、本体和保温层三者进行热压烧结，并且层间设置过渡层使三者结合更好，所得多层复合侧封板的整体性能更好，使用寿命更长。
