Description:
High Speed Slitting Line is a slitting line that can decoil a mother (original ) coil, slit the mother  (original ) coil into a certain number of small coils, and neatly recoil the slit baby coils at high speed of max 100-150m/min on the premise that slitting precision and recoiling uniformity are not ensured.

Work Flow
Coil-loading Car——Uncoiler——Coil-head Guide and Presser——Coil-head Straightener and Shoveler——Double-rollers Pinch feeder, Five-rollers Leveler —— Coil-head Shear——Hole Accumulator (1)——Entry Guide ——Disc Slitter —— Scrap Reeler——Hole Accumulator (2)——Pre-separator and Tensioner——Coils Pressing and Separating Bracket and Recoiler ——Coils Discharging Car 

Notes:
Uncoiler, or called "decoiler", has two styles of structure: one is single mandrel style, used for coil weight not more than 20T; the other is double mandrel style, used for heavy mother coils of 25Tons or more.
Coil head shear, or called "coil head cutter", to cut off the redundant coil heads of hot rolled coils.
(1) Hole Accumulator, or called "accumulation pit/loop" two structure can be chosen: one structure is one or one pair of turnover plates whose opening and closing are driven by hydraulic cylinders, the other is lifting bridge whose up-down-moving is driven by motor. Its function is to accumulate certain amount of steel strip in the hole so as to make sure the continuous high speed working of the line.
