无头轧制有明显的经济效益。为了扩大无头轧制技术的应用范围，用高频快速感应焊，在实验室条件下，按不同的模拟比，模拟了１５０ ｍ ｍ 方坯，２０ ｍ ｍ 厚板坯和３ 号角钢中间坯的对焊和轧制。模拟比分别为１∶１０、１∶５ 和１∶１。焊接后继续轧制的延伸系数分别为１０、５ 和２。材质为２０ＭｎＳｉＶ、２０ＭｎＳｉ、１６Ｍｎ 和Ｑ２３５。焊接后的坯料完全满足继续轧制的要求，轧制后焊口处的材料力学性能与基本材料的差距不超过１０ ％ 。
Headless rolling has obvious economic benefits. In order to enlarge the application range of endless rolling technology, high-frequency rapid induction welding was used to simulate the billet of 150 m, the blank of 20 m and the angle of 3 in different laboratory conditions Butt welding and rolling. The simulated ratios were 1:10, 1: 5 and 1: 1, respectively. The elongation coefficients of the continuous rolling after welding are 10, 5 and 2, respectively. The material is 20MnSiV, 20MnSi, 16Mn and Q235. After welding the blank fully meet the requirements of continued rolling, rolling after the weld material mechanical properties of the gap between the basic material does not exceed 10%.
