PROPOSAL FOR TUBE MILL 

1.  GENERAL DESCRIPTION

The proposed 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 shapes, longitudinal welding, sizing, converting into specified 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 id 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 though the cooling section. In sizing section, tube is formed to specified size and converted into specified shape. After sizing, tube is cut to specified size and converted into specified shape. After sizing, tube is cut to specified length by using flying cutting equipment and delivered in collecting though passing through run out conveyor.

1. BASIC DESIGN DATA

Design of the proposed line is based on following specification:

3. TECHNICAL DESCRIPTION AND SPECIFIATIONS

Uncoiler

This equipment is used for unwinding the coil.

Shearing & butt welding machine

In this unit the trailing end of a proceeding coil and the next coil passing through the mill are trimmed parallel by shear and then butt-welded together, these actions being controlled automatically or manually or by push buttons on the control board.

 Spiral accumulator

The reverse loop accumulator is installed between the shear& welder and the forming line, Its purpose is to give enough time for feeding the new coil from uncoiler to shear & welder to cut and join end of the new coil with tail end of previous coil.
