GB708-88 Hot / Cold Rolled Steel Strip Tube Mill Line Machinery Thickness 1.2-3.0mm
Technical parameters and offer about
ZG76(Enlarged toΦ115mm)pipe making machine
Description of product
This equipment is specially used for producingΦ48-Φ115mm, δ1.2-3.0mm high-frequency straight seam welded pipe and corresponding square pipe and special-shaped pipe(δ≤2.5mm). The composition of equipment is from uncoiler to fixed length cutting saw. Rolling speed can be adjusted correspondingly within suitable range of pipe diameter and wall thickness.
Dimension range of processing steel pipe:
(2) Wall thickness:1.2-3.0mm(square pipe and special-shape pipeδ≤2.5mm) (3)Length: 4-8M
Product (steel pipe) process flow:
Raw material (steel coil) → uncoiling → shearing and end welding → material accumulating → non-power leveling →mill-forming → high-frequency welding → removing burrs outside of weld seam → cooling → sizing → roughly straightening → fixed length cutting → finished pipe→run-out table
a.Equipment motor: 4KW+18.5KW+22KW+110KW×2+37KW+22KW = 323.5KW
b. solid-stateHigh-frequency welder: 250KW
Structure type: Single-side hydraulic-pressure expanding tight, which insure steel coil feeding alternatively and make steel strip go into accumulator freely.
Steel strip width: 150-360mm
Steel coil O.D.: Φ1200-Φ1500mm
Steel coil I.D.: Φ450-Φ550mm
Steel coil weight: Max.6000kgs
2.2 Shearing and butt-welding machine, which insure two coiled steel strips shearing tidily and then welding together and leveling weld seam.
2.3 Horizontal-type accumulator:
Usage: The steel strips stored in it shall be enough to ensure main machine to run continuously while welding two coiled strips.
