攀钢与重庆大学联合开发成功中间包无碳覆盖剂,使之彻底消除了使用碳化稻壳导致的中间包增碳问题的困扰。为开发IF钢和超低碳钢新产品创造了有利条件。首轮IF钢试验,已获成功。其中最大难点是控制成品钢中碳含量,攀钢采取了一系列技术措施,终于将碳含量控制在30×10-6的水平, Panzhihua Iron and Steel Co., Ltd. and Chongqing University jointly developed a successful tundish carbon-free coating agent, which completely eliminated the problem caused by using carbonized rice hulls tundish carbon problems. For the development of IF steel and ultra-low carbon steel products to create favorable conditions. The first round of IF steel test, has been successful. One of the biggest difficulties is to control the carbon content of finished steel, Panzhihua Iron and Steel has taken a series of technical measures, and finally to control the carbon content of 30 × 10-6 level,
