济南汽车制造总厂铸钢分厂有一条半自动多触头高压造型生产线。系1970年机电部济南铸锻机械研究所协助设计的,于1974年正式投入运行,是我国用于铸钢唯一的一条造型生产线,有小KW线之称。由于运行时间太长,改造前电气控制部分的故障特别多,生产线老化到离开撬棍就很难生产的程度。 1990年底该厂对这条造型线进行了改造,将电气部分改用可编程序控制器控制,使该线得到新生。 Jinan Automobile Manufacturing Plant Steel Branch has a semi-automatic multi-contact high-pressure molding production line. Department of Electrical and Mechanical Services in 1970 in Jinan Casting Machinery Research Institute to assist in the design, formally put into operation in 1974, China is the only one cast steel molding line, a small KW line. Due to the running time is too long, the electrical control part of the transformation before the failure of particularly large, aging production line to leave the crowbar is difficult to produce the extent. The end of 1990 the plant on this modeling line has been transformed, the electrical part of the programmable logic controller, so that the line was reborn.
