【Abstract】 The resin sand-coated iron mold casting process and principle of automatic control system(ACS)of production line was introduced. The characteristics of various logical controls such as electric motor drive,hydraulic drive and pneumatic drive were analyzed,as well as the principle of iron mold temperature control,control parameter setting of production line,alarm and self-diagnostic function were described. In order to solve the problem that the automatic control of the production line was instable,2 methods to eliminate interference factors was proposed. The practical usage situation of clients showed:this ACS not only met production need,elevated production efficiency,decreased working intensity and running cost,and also demonstrated the modern production level of foundry industry,and also had positive significance for the enterprise development and business promotion.更多还原
