超超临界叶片钢K11C77E的试制

Trial Production of the Steel K11C77E for the Blade of USC Steam Turbine

本钢在传统亚临界叶片钢的基础上开发生产了一系列超超临界叶片钢新品种,采用50t电弧炉冶炼→LF炉精炼→浇注3t电极→电渣重熔→保温→退火→800/650×4轧机流程生产K11C77EΦ200圆钢,能够很好地达到标准要求,满足用户需求。

Based on the production of traditional sub-critical blade steel, Ben-Steel developed a system new products of Ultra ultra critical blade, adopt 50t electric arc furnace smelting→LF refining→casting 3t electrode→electroslag remelting→holding→annealing→800/650×4 rolling mill→K11C77EФ200 round steel, be nicely able to the mark of user requirements.
