Inner hole anti-blocking coating of submersed nozzle for rare earth steel and submersed nozzle
The invention discloses an inner hole anti-blocking coating of a submersed nozzle for rare earth steel and the submersed nozzle. The inner hole anti-blocking coating of the submersed nozzle for the rare earth steel comprises yttria-stabilized zirconia, cerium oxide and lanthanum oxide. The mass ratio of yttria-stabilized zirconia to cerium oxide to lanthanum oxide is (90-95): (1-9): (1-9). According to the method, distillation of the inner hole body of the submersed nozzle in the rare earth steel continuous casting process is reduced, the service life of the submersed nozzle is prolonged, the number of continuous casting furnaces of a tundish is increased, and the castability of rare earth steel continuous casting is guaranteed.
本发明公开了一种稀土钢用浸入式水口内孔防堵塞涂层及浸入式水口，稀土钢用浸入式水口内孔防堵塞涂层的组分包括氧化钇稳定氧化锆、氧化铈和氧化镧；氧化钇稳定氧化锆、氧化铈和氧化镧的质量比为90～95:1～9:1～9。本发明减少稀土钢连铸过程中浸入式水口内孔体的结馏，提高浸入式水口的寿命和中间包连浇炉数，保证稀土钢连铸的可浇性。
