High Precision SS 304 Steel Coil Slitting Line Machine (0.3-3 X 1600)
High Precision Stainless Steel Coil slitting line must be very strong and very precise. Because, compared with normal carbon steel Yield strength ≤350Mpa Tensile strength≤550Mpa, stainless steel sheet strength is higher, Yield strength ≤550Mpa Tensile strength≤780Mpa.
Stainless steel sheet is high quality steel, its surface is bright and smooth, should be well protected in slitting process, all the transmission rollers will be PU rubber coated.

Characteristics
1. Very Strong decoiler and coil opening press roller and peeler shoveling plate, to hold steel coil steadily in time of steel strip being pulled out, and send strip head into pinch feeding equipment.
2.Slitter: slitter stands, shafts, knives are bigger and stronger than normal slitter. Drive motor power is about 50% more than normal model slitter.
3.All transmission rollers are PU rubber coated to avoid STS sheet surface from scratch.
4.Accumulator pit loop is longer and deep enough to make sure steel strip accumulating.
5.Tension provision unit own both roller and wool felt to provide adjustable stable tension for recoiling.
6.Recoiler has portal frame type overarm separator, from top to press separating strips.
7.Slitting speed usually are limited within 80m/min.
8.Slitting knives will be special material SKD11, H13K, SLD,etc.
9.Hydraulic system, such as hydraulic cylinders, valves, should be robust and more durable.
Slitting Precision:
- Slit widths tolerance:≦0.10mm; Slit width＜300mm, thickness ＜1.2mm, slit width tolerance≦0.05mm;
- Slit camber:≦0.5mm/M for strip of wider than 300mm, ≦1.0mm/M for strip of <300mm. The edge strips within 100mm of mother coil edge are not in the restriction.
- burrs:≦0.05mm, or say, no more than 5% of over 1mm thickness strip slitting at stable speed under conditions of sharp knives and proper knife gaps.
- Recoil staggering≦±0.5mm (at stable speed, speed change not so fast
- Recoil turriform:≦±2.0mm (at max coiling diameter
