(1) Under the condition that the forging process of the tube is stopped smoothly, the pouring temperature should be lowered as much as possible, and the pouring temperature of the copper rod is usually between 1150 and 1200 °C. (2) When forging a copper rod, it is possible to adopt a pure copper crystallizer, or to adopt a crystallizer with a graphite liner. (3) The production of copper rod ingots, as usual, adopts the power frequency and has the iron core to feel the electric furnace for melting and heat preservation equipment. (4) In the case where no crack occurs outside the tube ingot, even if the rate of forging is improved. (5) Before pouring, all the graphite components in the front chamber of the holding furnace and the liquid flow control system should be fully preheated, and the bracket should be sufficiently baked. (6) The gating system shall be able to extend the flow path as much as possible and to ensure that the casting process is stopped under the premise of sealing or covering (soot, graphite powder or shielding gas). (7) Because the thermal conductivity of the copper rod is good, the condensation rate is faster, the crack deflection is not obvious, and it is generally possible to adopt a relatively large cooling intensity.
