Hot rolled XLY Fully control Hi tech Acid Pickling Line with Big quantity
we are a powerful supplier who have joined the Trade Assurance to protect your payment to make sure that we deliver on time and manufacture quanlity products as required.
The hot rolled steel coil & hot stainless steel coil which are the basic raw material are passed through the continuous pickling line to remove the oxides from strip surface to enable further coil processing. This processing is requires since rust is formed on the surface of the coils at room temperature.

This system adopts the vertical arm hand type lifting device, compared with the traditional vehicle or electric hoist, with accurate positioning, no shake, can achieve a stable sling hold up and down, to avoid the slings and workpiece fall into the acid pool, and my company independent research and development of the hoisting device, with the PLC automatic control program, can be intelligent the lifting task is adjusted by the process of pickling time recording processing groove, adjust the hand task, reduce the load time, the precise control of the pickling time and automatically enter and put forward into the next process of pickling tank tank.
