Carbon-based ceramic side sealing plate for thin-strip continuous casting and preparation method of carbon-based ceramic side sealing plate
The invention provides a carbon-based ceramic side sealing plate for thin-strip continuous casting and a preparation method thereof.The preparation method comprises the steps that crystalline flake graphite, superfine graphite, zirconium oxide, boric anhydride, spinel, boron carbide, GLYDOLN1055 and T85 are weighed and stirred to be uniform, a mixed material is obtained, deionized water is added, stirring is conducted, and slurry is formed; carrying out spray drying, mixing with liquid phenolic resin, granulating, and sieving to obtain granulated powder; putting the granulated powder into a mold, and carrying out near-net-size forming by utilizing a hydraulic machine to obtain a green body; curing the green body; and placing the cured green body in a sagger, fully burying the green body with metal silicon powder, and placing the sagger in a vacuum electric furnace for segmented sintering to obtain the carbon-based side sealing plate. The side sealing plate prepared through the method has the advantages of being low in preparation cost and long in service life, the problem that the side sealing plate is poor in initial blank shell friction and wear resistance is solved, and meanwhile the service requirements of thin-strip continuous casting for molten steel erosion resistance, molten steel thermal shock resistance and friction and wear resistance of the side sealing plate are met.
本发明提供一种薄带连铸用碳基陶瓷侧封板及其制备方法，其制备方法为称取鳞片石墨、超细石墨、氧化锆、硼酐、尖晶石、碳化硼、GLYDOL®N1055和T85，搅拌均匀得到混合物料，加入去离水搅拌形成浆料；然后经喷雾干燥、与液体酚醛树脂混合混炼与造粒，过筛，得到造粒粉；将造粒粉置于模具中，利用液压机进行近净尺寸成型，得到坯体；将坯体进行固化；将固化后的坯体置于匣钵内，并用金属硅粉将其充分埋没，将匣钵置于真空电炉内进行分段烧结，即获得碳基侧封板。通过该方法制备的侧封板具有制备成本低、服役寿命长的特点，解决了困扰侧封板抗初生坯壳摩擦磨损性能不足的问题，同时满足薄带连铸对侧封板抗钢液侵蚀、抗钢液热冲击、耐摩擦摩损性的服役要求。
