Copper Rod CCR Production Line Cable Making Machine

The continuous casting and rolling production line is one of the most mature design of our company. The simple structure, high production efficiency, low energy consumption and excellent quality are main features of this production line. The production line has been awarded three national patents. It is the most advanced production line and widely recognized by customers both at home and abroad. The production line adopts the process of continuous casting and rolling. It can produce low oxygen bright copper rod of 8mm by using the copper ingot with the casting sectional area of 2,330 mm² . The raw material is cathode or red copper scrap. The new set replaces of copper rod continuous casting set in upward hauling type and traditional continuous casting and rolling set with 14 stands. The casting wheel is H type, during the pouring process, the vortex can be reduced greatly, so that the ingots internal bubble and crack also can be reduced efficiently, the ingots quality is better than the vertical pouring craft.

Products Details

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).
