| | The endless rolling has great advantages.In order to expand the application of this technique by use of induction heating for joining on butt blanks the bar,strip and angle endless rolling process was simulated in the laboratory.The specimens were 150 mm square,20 mm thick band and 30×30 mm angle.The simulation scale was 1∶10,1∶5 and 1∶1 respectively.After joining,the blanks were rolled.The elongate coefficient was 10,5 and 2 respectively.The materials tested were 20MnSiV,20MnSi,16Mn and Q235.The results ... | | 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 % 。 | | 文摘来源 | |   |
