Continuous rolling machine is composed of automatic feeding mechanism, main transmission case for motivity, each two sets of horizontal and vertical type two-roller rolling stand, 8 sets of φ 255Y type rolling stand
The speed ratio of the gears in the main trunk is designed as the most appropriate speed ratio among the stands. 40Cr, QT500 and 20CrMnTi gears with little noise, long life span and high precision are adopted in the main trunk according to different mechanic tension demand. The compressing ratio of the copper bars in the rolling mill is ensured equal, so that the situation that some components are damaged because of the unequal mechanic burden is efficiently avoided. The continuous rolling machine system is made up of 8 three-roller "Y" rolling mills. With a unique rolling method combing 2-high rolling stand and 3-high rolling stand, the rolling mill is entitled mangy advantages. On one hand, the rough rolling stand adopts the 2-high rolling stand, which has a big compressing ratio and is good for rolling and shaping the bars perfectly.

In this way, the density of the bars is increased as well. On the other hand, the finish rolling stand adopting the 3-high rolling stand, can make use of the 3-high rolling mill's feature to shaving the sides equally, so that the copper rod is of a good function and quality. The power of automatic feeding comes from the main transmission trunk and the bars are sent into the stand No. 1 by the cylinder. The safety pin is automatically cut in case of overload resulting from accidents in the rolling process, in order to protect the gears and axles. Compared with the rolling mill of generation one and two, the speed ratio between the neighboring stands is more reasonable and the gradual promotion is adopted. The cast bar section is increased to 2250mm² From the former 1800mm² , which is more good for casting flow control. The increased compression between the neighboring rolling mills and the gradual change of the various speed improve and perfect the compaction in the inner organization of the copper bars, and greatly improve the bars' ability to remove the potential cracks and bubbles. Thus, the copper rods' quality is improved dramatically.
