Different Types of Coil Processing Equipment
There are five main types of coil handling equipment: cut-to-length (CTL) units, cut-to-width (CTW) lines, slitting lines, cutting thick coils, and Rewinding Thick Coils.
Cut-to-Length Lines:
Cutting steel coils into sheet coils is what cut to length lines are best for. This equipment carries a spindle that moves the conveyor along with an upper belt conveyor that carries the coil. The spindle shears or cuts off a certain strip of metal from the coil, and it moves down to a lower conveyor belt that takes the product away.
Cut-to-Width Lines:
Cutting steel coils into thin strips for different applications is what cut-to-width lines are best for. This process is typically used for thicker coils that take more than one pass to cut. The finished product can then be used in many different ways, such as making beams and tubing. Cut-to-width lines produce cut-to-length pieces from coil weights of up to 30 thicknesses. Normally, the finished products will be processed further before they are shipped.
Slitting Lines:
When steel coil handling equipment needs to create thin, flat strips of steel for use in different applications, slitting lines are used. This type of process is best suited for thick coils that require the strip to be thinner after being cut. Slitting processes are repeatable and can be quickly modified to produce different widths and grades of steel.
Cutting Thick Coils:
Cutting thick coils can be difficult, as the coils curl during the cut. This is accomplished by using a top-tensioned shear head equipped with multiple blades that can strip through coils weighing up to 24 in [610 mm].
Rewinding Thick Coils:
When coil processing equipment needs to create thin, flat strips of steel for different applications, rewinding lines are used. This type of process is best suited for thick coils that require the strip to be thinner after being cut. Rewinding processes are repeatable and can be quickly modified to produce different widths and grades of steel.
How Does Coil Processing Equipment Work?
Coil processing machines depend on specific processes to get the job done:
Cut to length (CTL):
The steel coils are cut, and the piece is ready for use. This type of processing is best suited for thin sheet or plate stock.
Cut to width (CTW):
The steel coil is cut into a slim strip and then re-rolled for different applications. This is done by slitting the coil into thin strips with blades that are attached to two wheels called slitter reels. The wheel controls the head of the machine, which in turn moves the blades.
Slitting:
Steel coils are cut into smaller widths, and the strip is compressed into a coil shape. The finished product can then be used for applications that require smaller widths or different shapes. The metal coil is slit into a thinner strip by the slitter machine. This type of processing works well for thicker steel sheets or plate material. Slitting lines produce cut-to-length pieces from coil weights of up to 30 thicknesses. Roll feed lines are capable of 400 fpm with a production rate of 60 pieces per minute.
Uses of Coil Processing Equipment
- There are countless uses for coil processing equipment. Some examples include:
- Cut down steel strips into a specific size and shape for use as rebar or fence posts.
- Reducing sheet metal into thin strips for future processing.
- Producing thin steel strips that can be used in overhead cranes and conveyors.
- Cutting the coils up to make tubing, beams, bars, and rods.
The Benefits of Coil Processing Equipment
There are many benefits to coil processing equipment, such as:
Increased production rate:
Large coils can be difficult to handle and store, but coil processing equipment can reduce them into smaller pieces that are easier to transport and store.
Increased handling speeds:
When coil processing equipment is used, the processor will use an overhead crane to load and unload coils. This can speed up production because there are fewer manual steps involved in the process.
Reduced operator fatigue:
Coils can be heavy and awkward to handle, but coil processing equipment makes the job of cutting down loops easier on your back.
Greater flexibility:
The products made with coil processing equipment are always available thanks to various options. There are no additional costs for having multiple shapes or sizes of steel on hand, and the equipment can be used to produce new types of products.
Increased safety:
Coil processing machines have features that protect both workers and products from harm. Safety guards help keep your body away from danger while you work, and some units come with built-in stops as a means of preventing accidents.
It prevents material loss:
Ensures a greater yield of usable steel by providing the most significant possible piece is processed before cutting it down further.
Accuracy:
Coil processing machines are very accurate because the steel is typically fed into the machine through a roll. Because there can be no variation in the top or bottom edge of coils, cutting down with blades is more accurate than using saws to cut down coils.
Fewer errors:
When using coil processing equipment, the operator only needs to feed in one end of the metal and hit a button. The machine does all of the work and delivers a well-cut piece of steel.
Reduced labor cost:
It requires less time to cut down coils with blades than it would be if you were to cut them up manually. Coil processing equipment gives your employees more time to focus on other equally important tasks.
