2.2.Molten Copper or prepared Copper melt flows from the holding furnace into the casting machine via the launder, where it is cast into a trapezoid ingot with a cross-sectional area of 2300mm2. The Automatic shearer cuts off the waste end and press it smaller or pointed so as to feed into the rolling machine, where it is rolled, and after passing through the grease box and the guide pipe, aluminum rod is finally laid down in coil in the basket on the trolley.
