Abstract:

To achieve the goal that the automatic casting of Pb-Ca alloya can be realized on a linear casting machine, on the basis of the low slagging Pb-Ca all oy casting equipment, we study and develop an automatic casting control system whose core technology is PLC. The control system includes these controlling processes of synchronous movement, quantitative casting,constant weight keeping of the melt box, and so on, satisfies the demands of automation, exac   tness, and returnless pouring. This research provides a technical approach to the automatic Pb-Ca alloy production.
