隧道式酸洗磷化生产线及电气控制

Tunnel type pickling and phosphating production line and its electric control

盘条的酸洗磷化是PC低松弛预应力钢绞线生产的关键工序之一,隧道式酸洗磷化生产线与传统生产线相比生产效率高、工作环境好,操作人员的劳动强度低。该生产线采用环形设计,由上料台,在环形线运行的小车,下料台,工艺槽及电控系统组成。介绍隧道式酸洗磷化生产线的工作过程、控制原理及电气控制系统的硬件组成,说明菲尼克斯PLC编程软件的使用和昆仑通态组态软件实现的功能,给出运行小车的接线图、液位变送器的安装方式。使用表明,该生产线安全可靠,大幅降低生产成本。

The pickling and phosphating of wire rod is one of the key procedures of PC low-relaxation pre-stressed steel strand production. Comparing with traditional production line, to adopt tunnel pickling and phosphating production line is high production efficiency, good environment and low operating labor working intensity. The production line is designed in circle-shaped, made up of loading platform, vehicle running along circle, unloading platform, each process tank and elec- tric control system. The working process of tunnel type pickling and phosphating production line, control principle and hardware consist of electric control system were introduced. The usage of Phoenix PLC programmable software and function of MCGS configuration software realizing were illustrated. The connecting diagram of running vehicle and installation＇way of liquid level transmitter were given out. Results show that the production line is safe and steady, which reduces production cost dramatically.
