Cold rolling line

The cold-rolling line ROLL-12M-2P has been devised and manufactured to produce smooth and ribbed steel wire.
The wire rod rolls, having low content of Carbon, are rolled and the produced wire is winded on fixed or demountable metallic coils having maximum weight of 3 T.
The best technology, together with the best materials available, guarantee to our Customers:

Absolute reliability
Use and maintenance easiness
Constant and ongoing use up to 24 hours a day.

ROLL-12M is made up with the following units:

		SV-2T	Vertical decoiler To unwind wire rod rolls of max 2 T, with two supports of rolls, working with hydraulic turnover. Central upright with contrivance for down stroke od the upper pulley, with anti-node safety electric mechanism. Drive by hydraulic station.
		SC-5R	Mechanical descaler with 5 rollers The electro welded steel closed construction is provided with steel rollers. The machine is equipped with chip-basket for skale.
		ROT	Lubricating dust distributor Composed of a structure in electro welded steel for containing the lubricant and of a screw conveyor operated by gear, with mixer for the lubricant's transport on the wire. One additional screw conveyor in horizontal position takes back into the main tank the excess of lubricant which fall from the wire.
		CZL 3+3 RED	Rollers rolling cassette It carries out the first wire reduction. Two heads with three rollers with water cooling of pins.
		DV-2R	Deviator (ONLY FOR ROLL-12M-2P) A device that allows the use of the second reduction draft.
		CO15V-2-12M	Bull block It supplies the necessary power to carry out section reduction on the entry wire. The carrying structure is built in electro welded steel , complete with vibration-damping panels. The change-speed gears is provided with gears in Cr-Ni steel, hardened and ground on the profile.
		CZL 3+3 PRO	Rollers rolling cassette (ONLY FOR ROLL-12M-2P) It carries out the second wire reduction and, if requested, the ribbing.
		SN-7R	Stretching group with 7 rollers (OPTIONAL) To improve the ductility of the wire.
		SPO3T	Horizontal spooler It is able to wind steel on metallic reels. The carrying structure is built in electro welded steel, complete with vibration-damping panels. The movable tailstock and cradle for discharged reel is provided with hydraulic control. The variable pitch traverse mechanism, operated by AC geared motor, is synchronized with major motor.
		EC-ROLL12	Electrical control cabinet The box is completely sealed and thermically conditioned, and it contains all necessary components to make the line work and to check it. Control unit: Line controls Production statistics Error messages
