PICKLING PHOSPHATING SOAPING SHOT BLASTING
Pickling and phosphating treatments are operations made for wire rods surface to be apt to cold forming. Chemical pickling is made in order to remove completely the scale while phosphating and soaping allow an accumulation on the coil’s surface of a continuous and uniform layer composed by zinc phosphate crystals and zinc stearate. They form an efficient lubricant stratus for following operations of drawing, cold forming, extrusion and cold heading. We are also equipped to make shot blasting operations for wire rod.
In our standard offer we also include heat treatments on both drawn and peeled bars that includes annealing (from bell and continuous furnaces), quenching and tempering, normalizing and stress relieving (from induction heating lines).
