十流小方坯连铸机双中间包使用寿命提升生产实践

Production practice of improving service life of double tundish of ten-strand billet caster

为了提高十流小方坯连铸机双中间包使用寿命,通过实施中间包整体式稳流器、工作层渣线修砌、冲击区永久层等一系列改造、工艺优化的实施,解决了分体式稳流器、加强板易漂浮,工作层渣线部位侵蚀速率快、容易损坏,冲击区永久层不耐侵蚀等问题,十流小方坯连铸机中间包使用寿命得到了大幅度提升。

In order to improve the service life of double tundish of ten strand billet caster,through the implementation of a series of transformation and process optimization of tundish integral current stabilizer,repair and masonry of working layer slag line and permanent layer in impact zone,the problems of split current stabilizer and reinforcing plate easy to float,fast erosion rate and easy damage of working layer slag line and non erosion resistance of permanent layer in impact zone are solved,The service life of tundish of ten strand billet caster has been greatly improved.
