Combined line (for bars or coils)

The combined line ROLL-CL has been designed and produced by COM.IT in order to ensure, starting from wire rod, the production of smooth or ribbed wire for reinforced concrete bars, cut to size, or, alternatively, in the classic collection roll (spools or coils).

This new combined line ensures maximum efficiency and production capacity, combining the process of cold rolling with that of straightening, cutting to size and collection of the bars, while ensuring a high and constant level of quality of the finished product.

The phases of the production cycle are:

Cold rolling of wire rod
Pulling the rolled wire and straightening by rollers
Cut, with a measuring device and flying shears
Collection of cut bars and intermediate station that allows the tie and evacuation of the package of bars produced without stopping the production.

		Vertical decoiler It loads by means of hydraulically operated supports the wire rod rolls and it allows with a central pillar the correct unwinding at high working speeds.
		Mechanical descaler with rollers It descales the hot-rolled wire. The two central rollers are adjustable and change the scaling of the wire according to the needs.
		Lubricating dust distributor It lubricates the wire for the next rolling operation.
		Rollers rolling cassette allows the reduction of the wire and the eventual rib.
		Bull block it supplies the necessary power to carry out section reduction on the entry wire. It is equipped with a 190 kW motor.
		Drawing group and straightening rollers Device for pulling the wire after the bull-block and 4 series of rollers, arranged in orthogonal planes, through which the operation of straightening takes place.
		Encoder + Shear Device for measuring the length of the bars and give the command to the flying shear to cut the wire by the rotation of the two cutting knives.
		Cutting and collecting bench Cutting bench with length up to 12 meters. With the separator device uses two channels and allows you to collect the bars without stopping production. They will be collected and aligned in their cradles.
		Electrical control cabinet the box is completely sealed and thermally conditioned, and it contains all necessary components to make the line work and to check it Cutting bench with length up to 12 meters. With the separator device uses two channels and allows you to collect the bars without stopping production. They will be collected and aligned in their cradles.

		Water cooler Water cooling unit.
		Safety guards Optional, depending on the regulations of the country of the customer.
