Optimization and Modification of Billet-discharging Manipulator of 20 MN Piercing Mill

摘要: 從硬件、軟件和工藝特點(diǎn)等3方面對(duì)20 MN擴(kuò)孔機(jī)出料機(jī)械手進(jìn)行改造，并對(duì)其速度和角度進(jìn)行優(yōu)化。改造后的使用效果表明：將出料機(jī)械手的旋轉(zhuǎn)方向逆向旋轉(zhuǎn)90 °，基本消除了感應(yīng)爐“頂爐”事故的發(fā)生，降低了感應(yīng)爐的內(nèi)襯消耗，使內(nèi)襯的使用費(fèi)用從100元/t降低到45元/t，提高了感應(yīng)爐加熱坯料溫度的均勻性和擠壓成材率。

Abstract: 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.
