SLITTING LINE
Our slitting line is a highly efficient automated slitting equipment for steel strips. It unwinds and straightens the steel coils, then cuts the wide steel strips into narrow strips of the required width using rotary shears and finally winds and packages the finished strips using a winder. Widely used in the processing of rolled steel, the production of welded pipes, the production of steel structures and other industries, the equipment is a key complex for precise longitudinal cutting of strips.

Frequently Asked Questions
What types of plate materials can be cut on a slitting line?
It can cut various metal plates, such as hot rolled plates, cold rolled plates, galvanized plates, stainless steel plates and color coated plates. The specific model should be selected depending on the hardness and thickness of the material.
How to solve the problem of narrow strips waviness or curling after cutting?
It can be improved by optimizing dressing parameters, adjusting tension control, and checking blade clearance and edge sharpness. If necessary, a leveling device can be added to further stabilize the slab shape.
How long does it take to replace coils?
Replacing the coil takes about 10–15 minutes. Adjusting the cutting width requires changing shims and blades, which typically takes 30–60 minutes, depending on differences in specifications and operator skill.
