AHSS High Strength Coil Steel Slitting Line Machine ( Q460,C-Mn Steel)
AHSS mainly includes DP steel, TRIP steel, M steel, CP steel, HF steel, TWIP steel, QP steel, tensile strength 500 - 1500Mpa. in automobile industry, can largely improve strength at less mass
AHSS high strength steel sheets in coils are high quality steel, requiring high quality slitting. We make and supply AHSS coil steel coil slitting machines
Composition and 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.Edge scrap winder adopts torque type tension, stronger and efficient.
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 suitable for hard steel slitting.
9.Hydraulic system, such as hydraulic cylinders, valves, should be robust and more durable.
