This production line is used to produce low oxygen copper rod. It is characterized by simple construction, high output, low consumption of energy and good quality of copper rod.
Continuous casting and rolling process is adopted to produce low oxygen copper rod in 8mm diameter from cast bar with a cross sectional area of 2, 500mm2, with cathode copper or red copper scraps as the feedstock.
1. Composition
It is composed of melting furnace, tilting holding furnace, (reverberatory refining furnace), casting machine, automatic shearer, straigthening and polishing machine, rolling mill, oil lubricating system, cooling and de-oxidation unit, rod coiler, electrical control system.
2. Features
2.1 According to different kinds of raw material (copper cathode or copper scrap), we can equip with different types of copper treatment furnace to produce ETP rod and FRHC rod separately.
2.2 The continuous casting machine has been awarded with the patent right (patent No.: ZL200720079542.8). Casting wheel is of "H" type, which can be cooled from four sides to ensure the dense and even crystallization of the cast bar.
2.3 The continuous rolling mill has functions of automatic feeding and stop for rod pile-up. With a unique rolling mode combining two-high-roller stand with three-high-roller stand, the copper is provided with good mechanical property.
2.4 The main transmission system is in type of DC motor with full digital speed adjusting. By adopting PLC and man-machine interface, it can control the main machine and auxiliary components as complete line linked run. It can also monitor and display the running parameter of machines as well as indicate the failure.
