Uses
1. Our 1850-type steel coil slitting line serves to precisely break down diversified metal plates with the maximum width of 1850mm, the maximum coil weight of 30 tons, and the plate thickness from 0.3mm to 4.0mm. The metal plates to be slit encompass the cold-rolled sheets, electrolytic galvanized sheets, hot-dip galvanized sheets, color-coated sheets, stainless steel sheets, copper sheets, aluminum sheets, and much more.

2. Our company has sold one set of 1850-type steel coil slitting line to Shandong Xiaochuang Sheet Metal Processing Co., Ltd. This product has gone into operation without a hitch. Its quality and stability receives high level appraisal from our clientele. With high efficiency, this type machine can offer substantial benefit. It is fit for those customers who have high yearly output of machined plates with the width from 500mm to 1850mm. The metal plate with the width of less than 500mm had better be handled by the 1650-type or smaller sized equipment, so as not to waste resources.

Striking Points
1. The 1850-type steel coil slitting line gives the maximum speed of 200m/min and the width tolerance of ±0.05mm. The thickness of burrs is one thirtieth of that of the plate. The maximum quantity of strips to be slit reaches 30 pieces, and the minimum width of slit strips is 25mm.

2. Our product is configured with the dual blade holder. Its on-line production and off-line knife positioning system can save much time for positioning knives. Therefore, the processing efficiency of our equipment can be greatly raised.

3. By mounting the off-line separation device, the time for separation and configuration is also saved. Our powerful automation solutions can significantly reduce the operating time.

4. Moreover, the on-line edge scrap machine is equipped for coiling the edge material of over 2mm. Its speed is synchronous with that of the slitting machine. Alternatively, the off-line type tension-free coiling machine can be added for coiling the edge material of less than 2mm.

5. Beyond that, this 1850-type steel coil slitting line adopts the seamless winding technology. Its tension control system puts to use the wool felt. It can be also assembled with the RB21 series or BB series belt tensioner imported from Japan.

Features
1. Our 1850-type steel coil slitting line is characterized by gorgeous appearance, high-rigidity structure, as well as reasonable process layout.

2. The top-ranking processing, assembly and painting techniques allow the product to offer ultra high durability, low failure rate, and the reduction of both time and cost for maintenance.

3. In addition, the human-machine interface performs well. On the touch screen, many operations can be achieved, including the fault alarm, fault diagnosis, operating conditions, as well as the setting, modifying and commissioning order of technical data.

4. Owing to the adoption of perfect warning system, the touch screen will show the historical alarm information and real-time alarm information when the equipment failure occurs. Then, the system will activate the warning indicator at the top right corner of the touch screen, and at the same time the sound-light warning device will be forced to work. In this way, the operation of our equipment is made pretty smooth.

5. Last but not least, this 1850-type steel coil slitting line comes with multiple automation capabilities, such as fixed-length or fixed-weight slitting, the self-acting strip threading, the automatic loading of coiled materials, the automatic positioning of oblique mouth, the automatic processing of both loop strip and tailing, the self-acting centering of the center of the decoiler, the automatic regulation of the tension of the edge scrap machine, as well as the self-acting detection of the small-diameter tailing. Additionally, the height of the coil lifter can be regulated in compliance with the change of the coil diameter.
