This equipment is used for steel pipe straightener whose diameter is Φ101.6mm~355mm and thickness is 3mm~14mm. Main transmission adopts AC motor drive with the features of high accuracy, reliable, simple, convenient maintain and so on. The pipes pass the inlet roller, get into the straightening house and come out through outlet roller. All the operation is finished automatically or by linkage. The machine adopt upper and lower roller arrangement, vertical seven rollers including upper three and lower four, has high straightening accuracy. It can meet the requirements of relevant national standards on the type and straightness of steel pipes.

The operator operates the crane to directly lift the steel coil to the feeding center of the uncoiler. The uncoiler starts the mandrel expansion function to tightly stretch the steel coil onto mandrel. The uncoiler rotates actively to the uncoiling position. Manually, the welding strip (the welding strip fixed to the plate head after slitting) or the packing strap is cut off and removed (this process can be completed by the crane operator). The pressure rollers are used to guide the strip to the clamping and leveling workstation. The clamp rollers hold the steel strip forward and enter the leveler to level the strip head.

The vertical spiral accumulator is an important device for storing and releasing steel strips in continuous steel strip processing lines.

The metal strip butt machine for completing the cutting head of strip and butt welding work.

The slitting line is used for longitudinally slitting wide steel plates from steel coils.

There are pairs of pinch and leveller roll. Leveller rolls are arranged for two top and three below. Pinch and leveller is pressured by hydraulic cylinder, leveller roll motor is cogged by worm wheel and worm screw reduced speed, the worm screws in front and one in back can come true be in-phase by sleeve connecting, which can ensure top leveling roll and under leveling roll be parallel, thereby which reach in the intention of flatten.

It is used to store and drive strip steel. It is composed of power part, outer ring, horizontal roller table, vertical roll, inner ring, central discharge inner cage, transition roll, etc.
