overview
The cooling water comes from 4 zones (inside, outside, 2 lateral sides) of casting wheel and is divided to 9 paths, all cooling points are reasonable, so that ensure the grain structure of casting ingot is dense and well-distributed, and the quality is more excellent.
The rolling mill has 12 stands, No.1 to No. 4 stands are 2-roller type, the rest 8 stands are 3 - roller type, compression ratio from No.1 to No.6 stands has been increased greatly as well as improve the ingot grain structure effectively, in particularly cracks and bubbles can be eliminated, the quality of Φ8mm copper rod will be improved significantly, it is very easy for fine wire drawing. Equipped with hydraulic take-up, the coli is in good order and packaged, convenient for long-distance transportation. The quality of Ф8mm copper rod produced by this new type rolling mill is comparable to the SCR product.
The electric control system adopts DC main motor and advanced SIEMENS digital speed regulating device to make the speed of casting machine, rolling mill and take-up synchronized. Through PLC and human-computer interface, the system can achieve the coordinated control of main machine and auxiliary machines and display the running parameters and breakdown.
It is composed of melting copper refining furnace, Four 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 cathode, 8 tons shaft furnace (continuously producing).
