摘要
分析了十字型钢断面形状及轧制难度，介绍了孔型设计及导卫设计的特点，比较了横列式和半连续式轧制十字型钢的优缺点，提出了用半连续生产异型材的新举措。
In the paper, the author reviews the characteristics of roll pass design and guides - guards, analyses the profile of cross section and difficulty of rolling, compares the excellences and shortcomings of rolling technic of cross layout and semi - continuous layout, after that, it is pointed out that the semi - con- tinuous rolling measures are taken to produce complex section.
