The main features of this machine include:

High degree of automation: automatic feeding, automatic cutting, automatic winding, fully automatic control, no need for manual intervention, reducing manual labor in production.

High cutting accuracy: This machine adopts advanced cutting technology, which can achieve high-precision and high-speed cutting, effectively improving product quality.

Strong processing ability: The steel plate cutting line has strong processing ability, which can simultaneously process multiple steel plates of different specifications and thicknesses to meet different production needs.

Strong adaptability: This machine is not only suitable for cutting ordinary steel plates, but also for cutting different types of plates, such as stainless steel plates, color steel plates, etc.

Therefore, automatic steel plate cutting lines are widely used in the steel industry, especially in industries such as automotive manufacturing, aerospace, construction, and home appliances, with important application value.

Composition

Coil preparing saddle, Coil loading Car, Uncoiler, Coil head Opener, Pinch feeder & Pre-leveler, Shear, Pit accumulator 1, Entry guide, Slitter, Scrap winder, Pit Accumulator 2, Tensioner and Pre-separator, post shear and deflector roller, recoiler with overarm separator, coil discharging car, (turnstile)

  • Uncoiler: single mandrel cantilever type for coil load 15-20T or double taper heads uncoiler for 20 -30T
  • Pinch feeder and Preleveler: pinch feeding steel strip to slitter in Jog and feed strip into pit accumulator in automatic mode.
  • Slitter is the heart of the slitting line, install disc knives, spacers, rubber rings or wooden strips to realize slitting, double slitters fast exchange is optional
  • Slit tails press roller: installed on roll table over scrap winders, to press slit strips tails not fall into pit loop.
  • Scrap winder: vertical type or horizontal type is available, wind up edge scraps.
  • Strips separating: three times strips separating( twice before tension, once before recoiling).
  • Tensioning station: channels slotted beams clamp wool felt to provide ajustable recoiling tension.
  • Deflector encoding roller: deflect strips direction before recoiling and measure line speed to realize synchronization between slitter and recoiler
  • Recoiler: seamless mandrel or normal segments mandrel are available, to wind up strips in order under press strips separating.

Q & A

1.Q: What coil thickness and width can this slitting line handle?
A: Coils from 0.3 mm to 3 mm thick and 300 mm to 1300 mm wide. The uncoiler takes 508 mm inside diameter coils up to 1800 mm outside diameter and 20 t weight, which covers standard cold rolled, hot rolled and galvanized mill coils.

2.Q: How many strips can it produce in one pass?
A: About 25 strips when slitting 0.3-1 mm material and around 10 strips at 2.0-3.0 mm. The exact count depends on finished strip width and knife spacing, with a minimum slit width of 20 mm.

3.Q: What slitting speed and dimensional accuracy does it achieve?
A: Line speed is adjustable from 0 to 120 m/min. Slit width tolerance is held within plus or minus 0.10 mm and coil hump within 0.5 mm, measured on the recoiled strip after tensioning.

4.Q: Which knife and separator materials are used?
A: Disc knives in SKD11, SLD or H13K depending on the material being slit, with 45# steel spacers, rubber or PU cushion rings, nylon separators and 16Mn separating discs. Double slitter heads for fast knife changes are optional.

5.Q: What total power does the line need?
A: About 260 kW installed, of which 90 kW on the slitter and 110 kW on the recoiler, with the remainder on hydraulics and auxiliaries. A 380 V 50 Hz three-phase supply is standard and other voltages can be built to order.

Build standards and working accuracy

Which components and brands go into a slitting line?

Structural parts are welded to a minimum throat of two thirds the thinner plate, shot-blasted before painting and finished with two top coats. Uncoiler, slitter and recoiler shafts are forged 42CrMo and supplied with a material certificate; gears are 20CrMnTi, case-hardened and ground. Bearings, hydraulic, pneumatic and electrical parts come from named suppliers — Yuken valves, AirTac cylinders, HIWIN linear guides, Mitsubishi or Siemens PLC, Proface HMI, OMRON sensors — and the final bill of components is fixed on the approved drawing for each line.

What slitting and recoiling accuracy can the line hold?

On a typical slitting line, slit width is held to ±0.05 mm on strip narrower than 100 mm and thinner than 1.5 mm, and to ±0.10 mm in other conditions. Camber stays within 1.0 mm over 2 m, burr within 3% of strip thickness for strip up to 1.0 mm and 4% between 1.0 and 2.0 mm, winding misalignment within ±1.0 mm and telescope within ±2.0 mm. Final tolerances are agreed on the drawing for the specific line.

How is the line installed and supported after delivery?

Engineers attend the customer's plant to supervise installation and train the operators on the line as built. Spare parts are supplied at any time, and remote technical support stays available for the life of the machine.
