Embodiment 1

[0024] The continuous casting and rolling production technology of copper material of the present invention comprises the steps:

[0025] A) adding various raw materials of scrap copper into the open hearth furnace for refining;

[0026] B) The qualified copper liquid after refining is released from the copper outlet, flows into the ladle through the launder, and the ladle is equipped with a gas baking device. During the copper discharge, the ladle and the ladle are covered with charcoal. The temperature of the copper water is 1110°C, and the oxygen content is 140PPM;

[0027] C) The copper liquid in the ladle passes through the gate, and the stainless steel nozzle continuously and evenly enters the crystallization groove of the casting wheel, and is strongly cooled by the cooling water to crystallize. With the rotation of the casting wheel, the crystallization continues to increase at the ingot output position ;

[0028] D) The billet is separated from the casting wheel und...

Embodiment 2

[0069] During the casting process in step B, the temperature of the copper water in the ladle is 1110°C, and the oxygen content is 160PPM. Wherein the demoulding temperature of the slab in step D needs to be controlled at 940°C. Others are with embodiment 1.

Embodiment 3

[0071] During the casting process in step B, the temperature of the copper water in the ladle is 1110°C, and the oxygen content is 150PPM. Wherein the demoulding temperature of the slab in step D needs to be controlled at 940°C. Others are with embodiment 1.

Abstract

The invention discloses a continuous casting and rolling production technique for copper rods. The production technique comprises the following steps: A) a plurality of pieces of waste red copper are added in an open hearth for refining; B) qualified copper liquid after refining is discharged out, and flows in a casting ladle through a flowing groove; in the casting process, the temperature of copper water in the casting ladle is 1,110-1,130 DEG C, and the oxygen content is 140-160 PPM; C) the copper liquid in the casting ladle passes through a gate; a stainless steel casting nozzle is continuously and evenly introduced in a crystallization recess of a casting wheel, and is strongly cooled by cooling water for crystallizing; crystals are increased continuously along with the rotation of the casting wheel; D) casting blanks are separated from the casting wheel; E) the unqualified casting blanks are cut off by flying scissors; two acute angles at the upper parts of the casting blanks are removed; F) the casting blocks enter a rolling machine to be rolled into the copper rods; G) oxidization layers on the surfaces of the rolled copper rods are removed through a cleaning and cooling pipe; the temperature is reduced below 80 DEG C; H) the cleaning and cooling pipe is dried through a compressed air spray nozzle, and is conveyed to a rod winder by a clamping roller for rod winding . The production technique can produce the copper rods by using the plurality of pieces of waste copper; the produced copper rods have good quality.

Description

technical field [0001] The invention relates to a production process of copper materials, in particular to a continuous casting and rolling production process of copper rods. Background technique [0002] At present, how to smelt and produce copper rods for a variety of scrap copper mixed together is also very important to obtain high-quality copper rods. It has not been well solved in the copper production industry. Contents of the invention [0003] The purpose of the present invention is to provide a production process of continuous casting and cutting of copper rods which can produce copper rods with various waste coppers and which have high quality copper rods. [0004] In order to achieve the above object, the technical solution adopted in the present invention is: a continuous casting and rolling production process of copper material comprises the following steps: [0005] A) adding various raw materials of scrap copper into the open hearth furnace for refining; ...
