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 shape, longitudinal welding,sizing ,converting into specified shape and cutting to pre determined length.

Ø127 high-frequency welded tube mill line is designed to produce round tubes with diameter of Ø60-Ø127mm with Wall thickness of 1.5-4.0mm. This line utilizes roll forming to process steel strip into various shapes. Using high frequency induction heating ,this line is capable of producing section material of various diameters and sizes by squeezing weld seam together into closed shape. The products conform to BS/ASTM standard. Adopting the advantages of the equipment of the same kind at home and abroad, each element of the line is designed with new ideas. The application of advanced technology,PLC automatic control system and British Eurasia Digital speed regulating unit ensure that the production line Works reliably operates and British Eurasia Digital speed regulating unit ensure that the production line Works reliably operetes and maintains easily. Being the best production line in China it can also compete with the advanced ones in the World.

5)    Steel trip width:200-400

6.2 SHEAR AND WELDER

Shear and welder mainly Works for cutting clear of both ends of every strip and welding their butts with each other so as to ensure continuous production of pipes.

1)Maximum cutting thickness:4.0mm

2)Maximum cutting width:400mm

3)Mode of welding:manuel

6.3 HORIZONTAL ACCUMULATOR

 Working principle:Hydraulic cylinder of strip feding unit holds down steel strip. The feeding motor drives the feeding roll to fill strip into the accumulator by friction  force. The main motor rotates supply roll of the accumulator cage to store steel strip in the inner and outer storage zone. The drive motor will stop after one coil finished,and will resume feeding after cutting and welding of another coil.

Fixed rim accumulator:strip lead in from outer rim,and dischrge from center.

6.4 FORMING AND SIZING MILL

Forming Method: w forming,bottom line of tube constant for all sizes.
