The Roll-reducing machine is composed of eight pairs of rolling wheel at

90 degree angles. Each unit of rolling spindles is directly driven by geared motor after passing from twin output gearbox and universal joint.

Rolls are reduced gradually along a circumference direction to its axle and are done when pulled out from the straightener. Such procedure is widely used in the world currently, through which the rolls are sure to have smooth surface, fine roundness and uniformly stretched heating wires within the component. SG8A Roll-reducing Machine has high production efficiency, which reduces roll at 18m/min.Lubricating device is alternative for the roll while being reduced.

SG12B is using the OAKLEY (American) transmission bed and the CSM

(Italian) roller assembly. Speed of the output shafts of the twelve groups of gear cases has difference, which makes drawing to the tubes while reducing. Length of the tubes will be markedly increased after reduced by this machine, so it can save some materials. Tubes after reduced with smooth surface, roundness ＜ 0.05mm, straightness accuracy ＜ 0.5mm within 1000mm. There are two materials of the roller wheel, one is the

Cr12MOV or D2, the other one is hard alloy. Method of instilling lubrication can be chosen and auto stamping mechanism can be installed to the machine. With strong power, the machine can reduce heating tubes

SG14B Roll Reducing Machine

The structure of SG14B type tube reducing machine is basically the same with SG8/12B,in order to adapt to rolling into square tube or round tube with big diameter and longer length,the machine divide into fourteen groups to roll,reasonably distribute each group compression,it also adopt larger reduction ratio gearbox. It chooses different speed device according to different tube to meet all kinds of heating tube production demand.
