The Tube Mill is a combination of equipment installed in a line for the production of High Frequency Induction Welded (HFIW) carbon steel tubes. The process involved is cold forming of carbon steel strip in circular shape, longitudinal welding, sizing, converting into Rectangular/Square shape and cutting to pre determined length.
The complete line is divided in three sections:
- Entry Section
- Forming, Welding, Cooling and Sizing Section
- Cutting and Delivery Section
Raw material (Steel Strip) in form of a coil is uncoiled and fed into forming section passing through the equipment of entry section. Entry section enables the tube mill to run continuously by using strip joining and accumulation equipment. Tube is formed in round shape passing through a set of driven and idler rollers of forming section before welding. In welding section tube is longitudinally welded by using high frequency induction welding method. Outside bead is removed and formed in shape of scrap. The weld seam is ironed and tube passes through the cooling section. In sizing section, tube is formed to specified size and converted into Rectangular/Square shape. After sizing, tube is cut to specified length by using flying cutting equipment and delivered in collecting troughs passing through run out conveyor.
