Intermittent energy-saving wire winding system of copper upcasting continuous casting machine

Abstract

The invention discloses an intermittent energy-saving wire winding system of a copper upcasting continuous casting machine, comprising a continuous casting machine top-layer traction guide wheel, a continuous casting machine wire winding pushing wheel and a continuous casting machine wire winding driving motor, wherein the continuous casting machine wire winding driving motor is provided with a start-stop controller and an overload sensor; a pushing start sensor is arranged between the continuous casting machine top-layer traction guide wheel and the continuous casting machine wire winding pushing wheel, the pushing start sensor is arranged below casting copper; the start-stop controller is a relay, the pushing start sensor and the overload sensor input control signals to the start-stop controller in a manner of contact signal setting; the pushing start sensor inputs a control signal used for connecting a power supply circuit to the start-stop controller; and the overload sensor inputs a control signal used for disconnecting the power supply circuit to the start-stop controller. The system can adjust the wire winding speed of a wire winding device of the copper upcasting continuous casting machine in real time.

Description

technical field [0001] The invention relates to the technical field of continuous casting of oxygen-free copper rods by an upward drawing method, in particular to an intermittent energy-saving winding system for an upward drawing continuous casting machine for copper materials. Background technique [0002] Upward-drawing copper continuous casting machine is the upward-drawing oxygen-free copper rod continuous casting unit. The copper upward-drawing continuous casting machine is mainly used to produce long-length bright oxygen-free copper tubes and long-length bright oxygen-free copper flat profiles. The copper upward continuous casting machine can directly use electrolytic copper continuous casting to produce rods, pipes, slabs or other special-shaped materials of different specifications; the copper upward continuous casting machine is divided into 2000 tons, 3000 tons and 4000 tons according to the annual production capacity. ~60000 tons and 8000~12000 tons four grades. ...

AI Technical Summary

Problems solved by technology

[0003] Copper winding devices in the prior art are mainly divided into two types: synchronous continuous type and uniform speed intermittent type. The speeds are inconsistent, and the speeds of the two are basically close to each other mainly through manual adjustment. When the speed of one of the two changes significantly due to the influence of the voltage fluctuation of the driving power supply, it is easy to cause the copper material to be pulled too much and cause surface damage. Indentation, or deformation caused by excessive accumulation and bending of the copper material; the uniform speed intermittent winding device mainly controls the start and stop of the winding device operation manually, so the automation level is low; or the upper and lower parts of the cast copper are installed A contact sensor switch controls the start and stop of the winding motor. The contact sensor switch in the above method will cause bending damage to the cast copper
