1. Brief Introduction

The simple structure, high production efficiency, low energy consumption and high quality are main features of this production line. It adopts the process of continuous casting and rolling. It can produce low oxygen bright copper rod of ф8mm by using the copper ingot with the casting sectional area of 2,330 mm². The raw material is electrolytic copper or red copper scrap. The new set replaces of copper rod continuous casting set in upward pulling type and traditional continuous casting and rolling set with 14 stands.

 

It is composed of melting copper refining furnace (prepared by buyer), six-wheel continuous casting machine, auxiliary machine, rolling mill, copper rod cooling, reverting and take-up unit, emulsion cooling system, lubrication system and electric control system etc.

 

Using red copper scraps, reflection refining furnace should be employed. If raw material is electrolytic copper, 8 tons shaft furnace (continuously producing) and 6 tons holding furnace (including automatic lifting loading unit) can be chose.

 

2. Process Flow

The process flow is as follows:

Feeding, melting and refining →holding furnace →flume →continuous casting (casting die) →forward hauling →casting ingot treatment unit (shearer, conveyer, alignment, edge shaving, straightening, brushing machine) →rolling machine (automatic feeding) →continuous rolling →copper rod cooling and surface recovery treatment unit →continuous rod coiler →rod coiler

3. Raw Material

3.1 Using red copper scrap as the raw material, the mixture ratio is as the below：60% of the first grade copper plus 40% of the second grade copper.

3.1.1 The first class copper is made up of clean, non-tinning, non-alloy copper wire and cable. Broken or burnt wire is forbidden. (Pb﹤100, Sn﹤300, Ni﹤50, Zn﹤50, Fe﹤50, Sb﹤20)

3.1.2 The second class copper is made up of non-insulated wire with a small diameter, usually including telephone wire with varnish covered or paper insulated copper row, copper wire and thick or thin red copper rod. (Pb﹤1,000, Sn﹤800, Ni﹤150, Zn﹤300, Fe﹤500, Sb﹤100, S﹤200)
