Novel copper bar drawing casting process and equipment

Abstract

The invention discloses a novel copper bar drawing casting process and equipment. The technical method specifically comprises the following steps: (a) smelting: extruding molten liquid in a heat preservation furnace by an extruder into a graphite sleeve for forming; (b) condensation: condensing a copper bar initially formed in the step a through a water-cooled crystallizer; and (c) cooling: cooling the copper bar condensed in the step b through a cooling device, blowing out cold air by a cold air machine, uniformly spraying the cold air onto the copper bar through spraying holes in the inner wall of an annular sleeve, then blowing out air at normal temperature through a fan, and uniformly spraying the air onto the copper bar through the spraying holes in the inner wall of the annular sleeve to gradually cool the copper bar. The cooling effect is good, and the product quality is high. By procedures of smelting, twice cooling, drawing, drawing for stripping, cleaning and discharging, thenumber of subsequence procedures can be reduced, and the labor cost is reduced; furthermore, an all-in-one machine is controlled by a PLC (Programmable Logic Controller), so that the automation degree is high; and the produced copper bar product is stable in quality, clean, attractive and relatively high in quality.

Description

technical field [0001] The invention relates to the field of copper rod processing, in particular to a novel copper rod casting process and equipment. Background technique [0002] The traditional production process of copper rods is smelting→drawing→cutting. However, after the copper rods produced by this production process are cut into bars, they have to be drawn, peeled and unloaded separately in the subsequent sequence, and the labor cost is high; and the existing The equipment is mechanically controlled manually, the degree of automation is low, there are many human factors, and there are hidden dangers in product quality. [0003] Therefore, it is necessary to invent a kind of novel copper rod leading casting process and equipment to solve the above problems. Contents of the invention [0004] The purpose of the present invention is to provide a new copper rod casting process and equipment to solve the problems raised in the above background technology. [0005] In...
