摘　　要：从硬件、软件和工艺特点等3方面对20 MN扩孔机出料机械手进行改造,并对其速度和角度进行优化。改造后的使用效果表明:将出料机械手的旋转方向逆向旋转90°,基本消除了感应炉"顶炉"事故的发生,降低了感应炉的内衬消耗,使内衬的使用费用从100元/t降低到45元/t,提高了感应炉加热坯料温度的均匀性和挤压成材率。The billet-discharging manipulator of the 20 MN piercing mill is modified, focusing on the hardware, the software and the process characteristics etc., and the operation speed and rotation angle thereof are optimized. Actual operation result of the modified equipment shows that due to the fact that the manipulator is capable of rotating reversely with 90°, ceiling-hitting-caused damage of the induction heating furnace is almost eliminated. As a result, the furnace liner consumption is reduced, and the liner expense is in turn cut down form the original 100 RMB/t to 45 RMB/t. Moreover, the billet heating temperature homogeneity is improved, and the yield of extrusion operation enhanced as well.
