1993年本刊第3期曾刊登了济南钢铁总厂岳书元的“推钢机自动后退加速装置”一文,文中介绍的装置结构特点和电气控制原理与本厂基本相似,但某些方面不尽相同,现将本厂情况介绍如下,以便交流。本厂推钢机的进退装置如图1所示,前进电动机通过传动三角带,带动变速箱,驱动传动螺杆螺母,推动钢坯进入加热炉。推钢完毕,前进电动机停止,后退电动机起动,通过传动三角带,带动变速箱作反向运
In 1993, the third issue of Jinan Iron and Steel Plant had published the book Yue Shu-yuan’s “push automatic back acceleration device,” a text introduced in the device structure and electrical control principles are similar to the factory, but some aspects vary Now the factory situation is as follows, in order to exchange. Factory push pusher advance and retreat devices shown in Figure 1, the forward motor through the transmission belt, drive, drive screw nut, to promote the billet into the furnace. Pushed steel is completed, forward motor stop, back motor start, through the transmission belt, drive transmission for reverse
