Background technique

The multi-head wire drawing machine is a special equipment for drawing wire and cable conductors. The raw material copper rod is drawn into the required specifications by the multi-head wire drawing machine. Dies of different specifications form copper wires of uniform size, and enter the annealing chamber of the wire drawing machine to stabilize the performance of the copper wires.

In the annealing chamber of the wire drawing machine, in order to prevent the oxidative deformation of the copper wire and enhance the tensile properties, a high-temperature protective film needs to be formed on the surface of the copper wire. The traditional method is to use a steam generator to generate steam and fill it into the annealing chamber. This method has the following defects:

The steam generator mainly heats water through the heating tube to form steam to be discharged. Due to long-term operation, the scale in the heating tube will further reduce the service life of the heating tube;

The steam is attached to the surface of the copper wire, and spots will form after drying, which is not smooth;

Steam easily damages the nickel ring in the annealing chamber;

After the steam enters the annealing liquid pool after liquefaction, the concentration of the annealing liquid decreases and the liquid level increases;

The steam generator consumes a lot of energy and costs a lot;

The failure rate of the steam generator is high, and the maintenance cost is high;

It takes a long time to wait for the steam generator to run normally when starting up the equipment, and the labor cost is high;

It cannot be incorporated into the overall system of the equipment to realize automatic control.
