This machine is our company in order to meet the requirements of the international market, according to our company LW series unit combined with FF forming technology,developped the automatic square and rectangular tube mill line.The cold-formed multi-point pre-bending process is adopted to make the deformation soft, the deformation stress is not concentrated, and the strength of the steel pipe is improved. The molding process adopts a combined mold design, and a set of molds can produce rectangular steel pipes of any specification within the specified range. The rolls are completely shared, the rolls can be saved by 90%, the roll change time can be reduced by 90%, and the production capacity can be increased by 80%, which can meet the production mode of multiple varieties and small batches.
