General introduction
Cut-to-Length lines are the right technological solutions to ensure world-class quality of the products in terms of flatness and dimensional tolerances. The CTL machine line can do uncoiling, straightening, gauging, cross-cutting to length and stacking work. It mainly includes uncoiler, straightener, gauge, shearer, conveyor,stacker, hydraulic system, pneumatic system and electrical system, etc. The line can make sure of accurate feeding and shearing. It can be widely used in cold or hot rolled carbon steel, tinplate, stainless steel and all other kinds of metal materials with surface coating. The cut to length line is controlled by PLC system. The information of length, shearing numbers and speed can be input to the PLC systems via HMI(Human Machine Interface) touch screen. When the needed shearing quantity is reached the line can stop automatically. The line speed can be adjusted, It has a gauge with high precision, and whole line can work automatically and operate easily, smooth plates can be made.
