      Product Details

      Product Introduction

      The slitting machine is a key piece of equipment in industry for cutting wide metal or non-metallic coil materials into several narrow strips of the required width along the length direction. Its core working principle is to continuously roll-cut the material through the rotation of the upper and lower circular disc knife shafts.

      The following is a comprehensive introduction to the core features of the slitting and shearing machine:

      Core Structure & Unit Composition

      The core structure mainly consists of upper and lower knife shafts, fixed/movable frames, and a synchronous lifting mechanism. The knife shafts and frames undergo precise processing (such as turning, high-frequency treatment, grinding, and chrome plating, etc.) to ensure the rigidity and accuracy of the equipment.

      This series of production line is applicable to coils of various specifications. It is used for slitting the coil into required width for the use of punch line through the procedure of uncoiling, pre-leveling, cropping, slitting and recoiling. It has advantages such as proper layout, easy operation, highly automated and high production efficiency.

      This line is adaptable to process cold-rolled and hot-rolled coils, silicon steel coils, stainless coils, colored coils, aluminum coils, and all sorts of plated and coated coils, and it widely applies to many industries like automobiles, containers, household appliances, food packing, construction materials, etc.

      This line consists of loading cart, uncoiler, slitter, scrap winder, cropping shear, tension controller and coil recoiler, etc. Loop bridge, pinch and deviation corrector are equipped between each machine. This automatic coil processing line is an integration of mechanical, electrical, hydraulic and pneumatic technology.

      Frequently Asked Questions

      Q What types of materials can the coil slitting line process?
      The slitting line is capable of processing a wide range of materials, including cold-rolled and hot-rolled coils, silicon steel coils, stainless steel coils, colored coils, aluminum coils, as well as various plated and coated coils. It is suitable for industries such as automotive, containers, household appliances, food packaging, and construction materials.
      Q What is the maximum coil weight and width the line can handle?
      Depending on the model, the slitting line can handle coil widths ranging from 400 mm up to 1,600 mm and coil weights up to 16 tons. For example, the 3×1600 model supports coil widths of 500–1,600 mm with a maximum coil weight of 16T.
      Q How many strips can be slit in a single pass?
      The number of slitting strips varies by model. The 1.2×1250 and 3×1600 models support up to 25 strips per pass, the 6×1500 model supports up to 20 strips, and the 2×1250 model supports up to 15 strips per pass.
      Q What technologies are integrated into this automatic coil processing line?
      This automatic coil processing line is a comprehensive integration of mechanical, electrical, hydraulic, and pneumatic technologies. Key components include a loading cart, uncoiler, slitter, scrap winder, cropping shear, tension controller, and coil recoiler, with loop bridges, pinch rolls, and deviation correctors installed between each machine.
      Q What is the line speed range for different models?
      Line speeds vary by model: the 1.2×1250 model operates at 80–120 m/min, the 3×1600 model at 90–120 m/min, while the 2×1250 and 6×1500 models operate at 0–100 m/min and 0–60 m/min respectively, allowing flexible adjustment based on material type and thickness.
      Q What surface treatments are applied to the knife shafts and frames to ensure durability?
      To ensure maximum rigidity and precision, the knife shafts and frames undergo a series of precise manufacturing processes including turning, high-frequency heat treatment, precision grinding, and chrome plating. These treatments significantly enhance wear resistance, surface hardness, and dimensional accuracy of the core components.
