Want to know what equipment will be needed for copper production, how much money does it cost?
Drawing, because of the molecular structure of the metal, under the friction and external force will be outside the slope, the middle of the fire should be returned several times, so that molecules rearrange. Generally, vacuum (plus nitrogen as protective gas) annealing, small cable, multi strand wire, also using conductive annealing.
Small enterprises do not roll, pull the stalk equipment, usually buy oxygen free copper rod (oxygen copper rod before drawing, to be washed, washed and cleaned, environmental protection investment).
Single core cable with extruded, extruding or vertical wrapping, sulfide (make sulfur in rubber to form sulfur Lian, the rubber line).
