How do slitting lines operate?

Each contract in the metals sector presents a fresh, unique challenge. The increased need for coils with variable thickness and length has ushered in an era of precise and potent slitting carried out by cutting-edge slitting software, equipment, and instruments.

This article will describe the operation of a slitting line. Let's get going.

Why Use Coils?

This is a completed steel item that has been wound up after rolling, like a strip or sheet. Steel coils are frequently used for efficient processing, shipping, and packaging.

Companies that manufacture processing machinery, including those that deal with heat, energy, and food processing, use coils.

Water processing and storage, domestic partnerships, petrochemical and pharmaceutical equipment, medical equipment, offshore drilling platforms, and building and construction supplies

Let's now talk about the idea of coil slitting.

What is Slitting A Coil?

This shearing process reduces the breadth of a main or primary coil into many narrow coils. Steel strips typically range in thickness from 0.015 to 25.4mm.

Steel strips are used in a variety of industrial applications, although they are generally required for the following: plumbing, construction materials, automotive body panels, and electrical components.

appliances, including refrigerators, washers, and dryers.

Slitting is a method of cutting sheet metal that uses circular blades to cut large coils of metal into thinner sheets or to trim the edges of rolled sheets. With the aid of spacers, the slitter knives are concurrently positioned at two arbors.

These slitter spacers guarantee both horizontal clearance and cut depth. A vertical clearance is frequently used to preserve the strip edge's quality.

Through rubber stripper rings, the strip is aided throughout the operation and discharged from between the blades. Similar to guillotining, slitting simultaneously adds shearing and bending deformation.

The Steel Slitting Machine: What Is It?

Recoilers, slitters, and uncoilers are included in this. These three are all propelled by separate engines. Different methods of moving the material through the slitter knives are distinguished based on how these essential components are driven. Based on the material, the quantity of slits, and the sheet depth, the driving mode is chosen.

Slitting in the Straight Mode

The material is pushed through the uncoiler by the powered recoiler. Pull-through slitting is the process in which the material is predominantly fed into the recoiler by the slitter and uncoiler.

The slitter is likewise driven during straight-mode slitting. To ensure that the material passes through the slitting line at a constant pace, the motors must be synced. Better edge quality at all depths and the capacity to cut thin sheets are benefits of straight-mode slitting.

Slitting in the Free Loop Mode

Between the recoiler and the slitter, the material is given the opportunity to form a free loop in this mode. To produce well-wound coils, a tensioning unit must be placed in front of the recoiler. Poorly formed coils can be processed using this method.

The results of the slitting technique are influenced by internal tensions in the incoming coil and shape defects (length variances such as depth variation, twists, and buckles throughout the width).

Therefore, to correct these well-known flaws in the incoming coil, a tempered mill or leveler should be added to the slitting process. This ensures that the slitted strips will be of higher quality.
