1.Description of product
1.1 Summary:
This equipment is specially used for producingΦ19-Φ50.8mm, δ1.0-2.65mm high-frequency straight 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.
1.2 Applicable material:
(1) Hot or cold-rolled steel strip
(2) Material: Low-carbon steel, low alloy steel, galvanized steel strip
(3) The thickness of steel strip: 1.0-2.65mm
(4) The width of steel strip: 60-160mm
(5) I.D. of steel coil: Φ450-Φ550mm
(6) O.D. of steel coil: Φ800-Φ1200mm
(7)Maximum weight coil: 2000kgs
1.3 Dimension range of processing steel pipe:
(1)O.D.: Φ19-Φ50.8mm
(2)Wall thickness: 1.0-2.65mm(square pipe and special-shaped pipeδ≤2.5mm)
(3)Length: 4-8M
1.4 Product (steel pipe) process flow:
Raw material (steel coil) → uncoiling → shearing and butt-welding → material accumulating → non-power leveling →mill-forming → high-frequency welding → removing burrs outside of weld seam → cooling → sizing → roughly straightening → fixed length cutting → run-out table
1.5 Milling speed: 20-80M/min
1.6 High-frequency electrics power: 200 KW (solid state)
1.7 Advised user’s necessary accessories (only for reference):
(1)Mechanical equipment site: 40M × 4.5M (length × width)
(2)Electrical equipment site: 6M ×3M (length ×width)
(3)Machine unit foundation base (See supplier’s base drawing)
(4)Two sets of 5-ton overhead crane
(5)Power supply:
a. Equipment motor: 132KW+7.5KW+15KW+15KW =169.5KW
b. High-frequency electric: 200 KW (Solid state)
(6)Saw blades (Disk) for tracking saw, specification as per instruction book and quantity as per customer need.
(7)Magnetic bar (Impeder core) for welding pipe, purchase as per pipe making size.
(8)One set of Φ2", 32M high-pressure pumps for pipe-welding machine cooling.
(9)One set of cooling water pool for pipe-welding machine, the volume 30 M3 with water pipe, water pressure meter and valve. (Decide size and quantity when installation on site, purchase from market)
(10)Machine unit electric circuit. Before assembling, circuit must reach the electric cabinet of high-frequency room. Electric connection for high-frequency room to overall control table and button station. (Decide size and quantity when installation on site, purchase from market)
(11)High-frequency room for machine unit. Adopting ground or attic according to customer’s layout.
(12) One set of air compressor. (Purchase from market)
(13)Lifting equipment and tooling for installing machine, maximum weight of one part is 5 tons.
2.Introduction of main components:
2.1 Uncoiler:
