Anti-erosion submersed nozzle for special steel continuous casting and preparation method of anti-erosion submersed nozzle
The invention discloses an anti-erosion submersed nozzle for special steel continuous casting and a preparation method of the anti-erosion submersed nozzle. The anti-erosion submersed nozzle for special steel continuous casting comprises a main body and a slag line, wherein the main body is prepared from the following raw materials in percentage by weight: 60-80% of fused alumina, 3-6% of carbon fiber, 6-10% of hexagonal boron nitride and 11-27% of titanium diboride; an adhesive is added into the main body material, and the adhesive accounts for 8-14% of the total weight of the main body material; the slag line material is prepared from the following raw materials in percentage by weight: 66 to 78 percent of electric melting zirconium oxide, 2 to 4 percent of carbon fiber, 3.5 to 10 percent of hexagonal boron nitride, 5.5 to 12.5 percent of titanium diboride and 10 to 23 percent of zirconium diboride. A binding agent is added into the slag line material, and the binding agent accounts for 11-15% of the total weight of the slag line material. The submersed nozzle prepared in the invention shows excellent slag corrosion resistance and mechanical properties in the continuous casting process, the inner wall of the nozzle is not easy to form nodules, the service life of the nozzle is remarkably prolonged, and the number of furnaces for special steel continuous casting can be increased.
本申请公开了一种特种钢连铸用抗侵蚀浸入式水口及其制备方法。特种钢连铸用抗侵蚀浸入式水口包括主体和渣线，主体材料由如下重量百分比的原料制得：电熔刚玉60～80%、碳纤维3～6%、六方系氮化硼6～10%、二硼化钛11～27%；主体材料中加入粘接剂，结合剂占主体原料总重量的8～14%；渣线材料由如下重量百分比的原料制得：电熔氧化锆66～78%、碳纤维2～4%、六方系氮化硼3.5～10%、二硼化钛5.5～12.5%、二硼化锆10～23%；渣线材料中加入结合剂，结合剂占渣线原料总重量的11～15%。本申请制得的浸入式水口在连铸过程中表现出优异的抗渣侵蚀特性和力学性能，水口内壁不易结瘤，显著提高了水口的使用寿命，能够提高特种钢连铸的炉数。
