Slitting Line and Steel Coil Slitting Machine Manufacturers Rishbin

 Metal sheets or strips suppliers always need slitting machine and cut to length machine line for the production of metal sheets with different widths or lengths from GI, PPGI, or stainless coils in large quantities. A steel mill most of time produces only wide steel coils, and steel or metal fabricators always use a slitting and cut to length machine line to manufacture steel strips with different widths or metal sheets with fixed lengths. A metal slitting machine line has been designed to cut longitudinally the wide steel coils into different narrow steel strips for continuously producing cold formed sectional steel products. Basically there are two types: high-speed and normal-speed slitting machine line. Steel slitting line can works at max speed over 150 m/minute and over 10 strips can be produced; while a normal-speed slitting machine can work at most 40m/min with less than 10 strips slit.


Cold Roll Steel Slitting Line

steel coil processing

The slitting line for cutting narrow coils from main coils. For widths of up to 3000 mm, thicknesses of up to 25 mm and speeds of up to 200 m/min.
The lines are composed of high-precision slitters with quick tooling change for slitter, tensioning device and recoiler. High-capacity recoilers. Extraction from coils without banding. Scrap ballers or scrap choppers. Moving tensioning devices with incorporated leveling.
Totally computer-controlled with diagnosis, automatic coil feed, and quality control.
For carbon steel, exposed and non exposed materials, stainless steel, pre-painted steel, aluminum and other metals.

Simple Steel Slitting Line


Simple Steel Slitting Line

Coil Feeding Equipment
The complete line is consists of one manually decoiler with a capacity of 10000Kgs. The steel sheet is feeding to the leveling equipment under the function of friction and traction. The decoiler's running speed can be matched with cutting machine speed which controls the switch and has a press arm to press the coil to avoid the coil loose during rotation. Also, the hydraulic station is separate; it is off without expanding, which can save the power. It is only for this decoiler, so it can be used separately.

Guiding Equipment  of steel slitting machine
Adopting guiding bar and sliding block to control the width and position of the steel sheet. The coil is guided in the correct position and passed to the roll forming equipment.

Slitting device
The machine has three rubber pinching rollers to drive the sheet. Transfer the main motor power to the rollers through chains and sprockets, and also transfer the coil sheet. This device slits the sheet, adjust the slitting blade and can slit different sizes. And guide device is also included, so it is convenient to adjust the slitting size manually.
