Direct Forming To Square Tube Mill
1) The shape at the edge of cross section, comparatively, and the brim is flat, the side is regular, perfect shape of tube.2) the whole line load is low.3) The width of steel strip is about 4-7% smaller than that of round into square/rectangular, it can save the cost of raw material. 4) It adopts the multi-point bending way, avoid the axial force and side abrasion5) Reduce the cost about 80% on roller.6) No need to replace the Rollers when change tube size,It greatly reduces the roller changing time, reduces the labor intensity, improves the production efficiency.
