点击图片查看大图Welded tube mill in the process of manufacturing square pipes, rectangle pipes with direct shaping and molding technology, combined type rollers are used with pieces structure, roller sleeves are filled between roller pieces, In the deformation region, rollers contact strip steel partially not fully, reducing the contact area and reducing the friction between strip steel and rollers accordingly. As a result, roller consumption is little and the energy consumption of units molding is also reduced remarkably accordingly.
According to users’ needs, the welded tube mill machines can be designed into the multifunctional combination equipments for producing section steel, square pipes and round pipes, realizing one machine with multiple functions.
Value highlights:
The roller sharing rate is as high as 100%;
Eclectic adjusting the roller spaces;
Save
