Slitting Machine	Decoiler	Tension-Free Coiling Machine for Edge Scrap	Coiling Machine

Features
1. Our 1250-type steel coil slitting line is provided with elegant appearance and rational process layout. Its maximum speed is 200m/min, and the width tolerance is ±0.05mm. The thickness of burrs is one thirtieth of that of the plate. Furthermore, the maximum quantity of the slit strips is 30, and the minimum width of the slit strips reaches 15mm.

2. As a configuration of our product, the double knife holder is accompanied with the on-line production and off-line knife positioning system. This greatly saves the time for positioning knives. Moreover, the powerful automation capability allows the operating time to be significantly reduced.

3. This 1250-type steel coil slitting line adopts the seamless winding technology. Its tension control system makes use of the wool felt. Also, it can be equipped with either RB21 series or BB series belt tensioner imported from Japan.

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

5. Furthermore, the human-machine interface gives wonderful performance.
a. Through the touch screen, the user is allowed to accomplish such operations as the fault alarm, fault diagnosis, operating conditions, as well as the setting, modifying and commissioning of technical parameters.
b. When the equipment breaks down, the touch screen will display both historical alarm information and real-time alarm information. Then, the system will activate the warning indicator at the top right corner of the touch screen. Meanwhile, the sound-light warning light is forced to work. In this way, our equipment can be operated smoothly.

6. The another highlight is strong automation capability.
Our 1250-type steel coil slitting line offers such functions as the automatic loading of coiled materials, the self-acting strip threading, the automatic processing of both loop strip and tailing, the self-driven positioning of oblique mouth, the fixed-length cutting, fixed-weight cutting, the automatic centering of the center of the decoiler, and the automatic regulation of the tension of the edge scrap machine. In addition, the height of the coil lifter can be adjusted on basis of the change of the coil diameter.

7. The high-precision processing equipment and high-quality purchased components can offer the top-ranking machining, assembly and painting techniques. Then, our 1250-type steel coil slitting line is provided with low failure rate and ultra high stability. Both time and cost for maintenance can be also reduced.

Applications
1. In use of 1250-type steel coil slitting line, the metal plates with the thickness from 0.3mm to 4.0mm can be precisely cut. The maximum width of the plate to be slit is 1300mm, and the maximum weight of the coil reaches 17 tons.
2. Our product is applicable for processing and cutting the cold-rolled sheets, electrolytic galvanized sheets, hot-dip galvanized sheets, color-coated sheets, stainless steel sheets, aluminum sheets, copper sheets, and some others.
3. With high efficiency, this type machine can bring about considerable benefits. It is proper for those customers who have high annual output of machined plates with the width from 200mm to 1300mm.
4. Our company has cooperated with Taiwan Chunyuan Company, and produced one set of 1250-type steel coil slitting line. This line is dedicated for processing electrical steel, and it has gone into operation without a hitch. Its quality and stability are highly appreciated by our clients.
