SPECIFICATION:
ZJ1300x (0.9-5)mm slitting line (double slitter switchover)
FUNCTION:
This line is apply for various kinds of steel plates slitting, recoiling. It used to uncoiling large coil drum plate, and slitting into umpty strips as required width, then to recoiling and packing into whole bale of plane plate for next procedure of cold-bending, punching, pipe welder, etc.
TECHNOLOGICAL PROCESS & TECHNICAL PARAMETER
Working Process:
Charging—uncoiling—pressing and guiding—pinch preleveler—scrap shear—transitional worktable —guiding—slitting(double slitter switchover)—scrap winding—hydraulic loop bridge —pre-separating—damping pressing—separating—recoiling—manual baling—discharging.
