Round to square pipe mill without roller changing is our company new product. During the diameter changing, the whole complete forming line does not need to change the roller in compared with before precise forming roller changing. Sizing section bears the responsibility for the work from round to square. Our mill adopts the newest technology. The sizing section from round to square does not need the roller changing too. This kind of technology not only avoids the large investment on the roller, which is suitable for the large and medium mill. When the diameter changing, the roller adjustment is complete automatic. It only needs to input the diameter, pipe wall thickness, material and other parameter in the IPC. Then, the entire roller will be automatically adjusted to the right position. Then, the machine can be started directly to have the production. A lot of time can be saved for the roller changing to let the variety diameters pipes production in little quantity to be possible. It improves the machine efficiency and machine starting rate. Besides, automatic adjustment can make the adjustment accurate, decrease the error on the manual adjustment, improve the qualified rate, and the economic efficiency.
