Main aspects of welded pipe mill line
1.Merchandise process flow:
uncoiling → butt and shearing-welding → accumulator→ feeding and leveling→ mill-developing higher-frequency welding → getting rid of burrs away from weld seam → cooling → sizing →straightening → repaired length reducing → work-out kitchen table
2. Primary elements
Structure kind: Dual-area 360orotary handbook expanding tight, which insure steel coil giving on the other hand to make steel strip enter into accumulator openly.
2.2 butt and Shearing-welding machine: (Users Prepare it on their own or Purchase from industry)
butt and Shearing-welding machine, which make sure two-coiled metal strips shearing tidily and then welding with each other and leveling weld seam.
The steel pieces kept in it shall be sufficient to make certain principal steel coil packaging machine to operate constantly although welding two coiled strips.
(1). Construction: Plate portion with automatic giving and delivery program.
(2). Adjusting technique: Manual spiral modifying.
(3). Gathering quantity: 150-300m.
2.4 welding, sizing and Forming device:
2.4.1 Providing device:
Straight manual roll: a single kind of vertical guide roll on the transfer.
Roller for questing: 7 Rollers for progressing which behind the information roll are passively leveled for questing strip metal to create metal strips go into forming gadget.
2.4.2 Creating device:
Mainly approximately mill-developing metal strip packing machine and controlling weld seam.
The requirements of forming product:
Stay of roller quantity Size of horizontal roll’s shaft materials
Horizontal roll stand 7 φ36 millimeters 40Cr
Top to bottom roll remain 8 φ20 mm 45#
The request of forming product:
1.The Dwelling of horizontal roll stand like dragon entrance.
2.The Structure of Straight roll stand is package-kind. Two set of straight guide roll.
3.The way of transforming rollers: pulls on the area
