Line design and principle of operation

From drawing mill (rolling mill) the wire is fed to the in-line annealer. The annealer is comprised of the upper and lower disks, induction heater, frame and decorative protective lining. Inside the annealer the wire is heated up to the defined temperature (as per the regulations) whereupon it is being cooled and cleaned in the pipe into which the cleaning solution is supplied under pressure from the opposite direction. The gravity flow of spent solution gets into the holding tank.

In order to stabilize the temperature of the cleaning solution the equipment includes a heat exchanger that guarantees the set temperature parameters in the recirculation mode.

The wire cooling speed in the pipe (ducting) is governed by the consumption of the cleaning solution fed by the pump.

Having passed the heating, cooling and cleaning phase the wire is delivered into the feeder in soft condition. With the aid of the drawing rolls the feeder pushes the wire through the ducting, whereupon the bending rolls with defined curvature exhaust it into the spooling device.

The freespool delivery table has been rotating at the alternate angular speed under the set program, thus ensuring the distribution of layers by the coil width. The linear speeds of the annealer, the feeder and the spooler are synchronized with the linear speed of the drawing mill in order to avoid any wire damage and ruptures; to this end all the electric wires have been provided with ‘in-house’ frequency converters. The coil of soft wire, its weight complying with the weight of the input coil, is preliminary bound at the freespool delivery table; the coil is afterwards removed and conveyed for grading and packaging by the onsite hoisting equipment.
