Steel Strip Slitting Lines

Slitting lines of steel strip are widely used in all kinds of sheet metal forming lines across the global industrial sectors. In the metal working industry, there are primarily two models of metal working procedures, and one is metal cutting which people are very familiar such as machinery tapping, boring, and grinding, or other traditional tool cutting processes. And the other model is metal forming, such as slitting, pressing, and drawing. Metal forming is the formation process that gives the raw material new form. Metal coil is a form of metal materials coiled into an assembled roll that is convenient for consumers to deliver their raw materials. Once it is to be used in the metal forming industry, automatic steel strip slitting lines are widely applied in all kinds of industries for the best convenience in manufacture. Metal Coil slitting is much like roll slitting, which is a shearing operation that cuts a large roll of materials into narrower rolls for industrial users in their production plants.

Type of Slitting Lines

For the mass production utilizing sheet metals, slitting lines of steel strip are widely used in all kinds of sheet metal forming lines across the global industrial sectors. In the metal working industry, there are primarily two models of metal working procedures, and one is metal cutting which people are very familiar such as machinery tapping, boring, and grinding, or other traditional tool cutting processes. And the other model is metal forming, such as slitting, pressing, and drawing. Metal forming is the formation process that gives the raw material new form.

Once it is to be used in the metal forming industry, automatic steel strip slitting lines are widely applied in all kinds of industries for the best convenience in manufacture. Metal Coil slitting is much like roll slitting, which is a shearing operation that cuts a large roll of materials into narrower rolls for industrial users in their production plants.

Metals and forming procedures

The procedure of metal forming is the formation process that gives the raw material new form. Metal coil is a form of metal materials coiled into an assembled roll that is convenient for consumers to deliver their raw materials. Once it is to be used in the metal forming industry, automatic metal coil slitting lines are widely applied in all kinds of industries for the best convenience in manufacture. Metal Coil slitting is much like roll slitting, which is a shearing operation that cuts a large roll of materials into narrower rolls for industrial users in their production plants. Within the slitting inventory, there are two types of slitting methods commonly known by the users, and the first one is log slitting and another is the rewind slitting. These two are the main two classifications.

Speaking of the log slitting case, the roll of material is treated as a whole part and one or more slices are taken from it without an unrolling procedure. Regarding the rewind slitting case, the web is unwound and run through the machine, passing through knives or lasers, and before being rewound on one or more shafts to form the narrower rolls. The present article discusses about the two methods and the corresponding applications.

All the supportive accessories

During operation procedure, if the targeted metal coils are to be slit, onsite operators would handle the coil toll to be rewound out of the roll and then the slit mechanism works to cut the coil into scheduled pieces. On the viewpoint of industrial insiders in the metal forming industry, automatic steel coil slitting lines are widely applied in all kinds of industries for the best working ergonomics. In fact, coil slitting is much like roll slitting, which is a shearing operation that cuts a large roll of materials into narrower rolls for users. In among the inventory, there are two types of slitting models. Regarding the log slitting case, the roll of material is treated as a whole part and one or more slices are taken from it without an unrolling procedure to make the things done. And after that, regarding the rewind slitting case, the web is unwound and run through the machine, passing through knives or lasers, and before being rewound on one or more shafts to form the narrower rolls.

Smart slitting

Smart slitting is like any other subjects in the industry now. Slitting specifications are complicated, and the specifications vary, yet the arrangement is different. If the materials are soft then it is another story. Meanwhile, for the soft materials there are several methods which are available for soft materials such as plastic films, textiles, adhesive tapes, and paper. Razor blades, straight, or circular blades are widely adopted, and some blades cut through the material while others crush the material against a hard roll. Those are more similar to knives in an extent. Moreover, the cutting blades can be set to a desired width, and some machines have many blades and can produce a number of output rolls at once, so the slit material is rewound on paper, plastic or metal cores on the exit side of the machines. Therefore, this process is adopted due to its low cost and high precision for mass production business model, and some machines have a program that monitors the blades and sharpens the blades in order to maintain the quality and precision of the performance of the slitting lines in the manufacturing sites.

Rewinding of the steel strips

Regarding the rewind slitting case, the web is unwound and run through the machine, passing through knives or lasers, and before being rewound on one or more shafts to form the narrower rolls. In fact, the multiple narrower strips of material may be known as the multiple or pancakes if their diameter is much more than their width. For the slitting of hard materials, such as sheet metal materials, blades cannot be used as the cutting tools. Rather, a modified form of shearing is utilized. Two cylindrical rolls with matching ribs and grooves are applied to cut a large roll into multiple narrower rolls, and this continuous production process is economic and most importantly, precise in a great scale.
