一、前言 近年来,随着世界各国钢产量大幅度增长,连铸钢的产量也逐年增加,连铸的钢种也逐年增多,质量不断提高。由于连铸具有生产效率高、可以省去初轧,节约能源、减少设备、占地面积小、成材率高等优点,连铸还可以减少钢中成分偏析,使夹杂物细小弥散,从而使材料纵横向性能均匀,如果冶铸工艺合适,可以获得性能良好的钢材。
I. Introduction In recent years, with the substantial increase of steel output in various countries in the world, the output of continuous casting steel also increases year by year. The continuous casting steel grades also increase year by year, and the quality is continuously improved. As the continuous casting has the advantages of high production efficiency, can eliminate the initial rolling, energy conservation, reduce equipment, small footprint, high yield rate, continuous casting can also reduce the composition segregation of steel, small inclusions so that the material aspect To the performance of uniform, if the smelting process is appropriate, you can get good performance of steel.
