Supply & Demand

ERW168 Material: S355 Production range: Round tube 76-168mm Square tube 60*60 - 130*130mm Rectangular tube 40*80 - 120*140 Steel coil wall thickness: 1.8-6.0mm

Features: 1)Compare with round into square & rectangle forming way, this way is better for the shape at the edge of cross section,comparatively, semidiameter of inner rac is small, and the brim is flat, the side is regular, perfect shape of 2)And the whole line load is low, especially the sizing section. 3)The width of steel strip is about 2.4-3% 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 abrasion,reduce the forming step while ensure the quality, meanwhile it reduce the power wastage and roller abrasion. 5) It adopts the combined type roller on the most of the stands, it realizes that one set of roller can produce all the sizes of square/rectangular tubes with different specifications, it decrease the store of roller, reduce the cost about80% on roller, Fast the bankroll tumover, short the time on new product design. 6) All the Rollers are common shares, no need to replace the Rollers when change tube size, only adjusting the Position of Rollers by Motor or PLC, and realized the full automatic control; It greatly reduces the roller changing time, reduces the labor intensity, improves the production efficiency.

FFX Technology Features: (1) lt can save 60% cost on rollers. (2) One set of Roller can be common used to product all the Round Pipe Range at breakdown section. And the Roller in breakdown section needn't be changed, and the position of Rollers adjusted Automatically; (3) Cut down the Size Changing Time. (4) Greatly reduce the intensity of labor. (5) It is convenient to restore and adjust roller.

Features 1.High Speed: Running speed can be reach 150m/min 2.Quick Change System: Small diameter tube mill adopts complete fast change structure, greatly reduce the time of roller changing. Large diameter pipe mill adopts exclusive quick change system. 3.High Precision: Ovality of pipe can be reached to±0.03mm, which is used to produce high precision pipe, such as cylinder tube, transmission shaft tube, etc.
