Either the work roll or the backup roll is driven, depending on customer requirements. The diameter of the 4high work rolls amounts to approximately 1:4 in relation to the barrel length. This type of rolling mill is mainly used in offline applications for cold rolling of soft and medium strip and for a wide range of strip widths, as well as ...
cast slabs into plate, the plate into hot rolled coils and the hot rolled coil into cold rolled coil. Many of these old mills are still running today as a result of upgraded electrical and hydraulic systems, including hydraulic screwdowns, hydraulic roll bend, and tension control.

The cold mill roll gap should start out being set to the same profile as the crown of the incoming hot mill product. Then, as the cold mill gap is adjusted to reduce the crown, the coil also will come out flatif the hot mill got the relationship between crown and flatness right to begin with. If the cold mill rolls or hot mill coils have too ...
Steel Steel Hot strip: The rolling of hot strip begins with a slab, which is inspected and, if necessary, surface cleaned either manually or by scarfing machines with oxyacetylene torches. The slabs are then pushed, or walked on their broadside, through gasfired furnaces that have a hearth dimension of about 13 metres by 30 metres. In a pushertype furnace, the slabs slide on watercooled ...
Apr 19, 2019· To be installed in Ningbo, Zhejiang Province, eastern China, the new 20 high cold finishing mills for Ningbo Powerway Alloy Material Co will competitively roll .
Nov 12, 2013· the roll gap, or the roll bite) between the work rolls. In this region the metal is plastically deformed, and there is slipping between the strip and the work roll surface. The necessary compression force is applied by hydraulic rams, or in many older mills by a screw arrangement driven by an electric motor [6]. Figure 1.
Honeywell''s Automatic Gauge Control (AGC) and Hydraulic Gap Control (HGC), incorporated with the MetalsMaster gauging system, enable mills to deliver the right gauge thickness with the least product variation. It also offers Target Adaptive control to increase yield, .

18 Roll Hydraulic Rolling Mill There are two types of 18roll hydraulic rolling mill—Zhigh type and Shigh type, in which 4 sets of side support devices are added to the HC six roll mill. The rolling mill is suitable for processing stainless steel, carbon steel and nonferrous metal strips.
HGC (Hydraulic Gap Control) cylinder. The AGC system provides the reference value for the HGC positioning system. Figure 1 Schematic structure of a hot rolling mill The thickness of the rolled material is measured by an XRay thickness gauge in the last pass. This measurement is possible within several meters distance from the
Jun 12, 2015· In order to improve the control performance of strip rolling mill, theoretical model of the hydraulic gap control (HGC) system was established. HGC system offline identification scheme was designed for a tandem cold strip mill, the system model parameters were identified by ARX model, and the identified model was verified. Taking the offline identified parameters as the initial values, online ...

Fastresponse thickness control ; Highaccuracy gap positioning ; Smaller thickness tolerances and faster thickness correction ; Reliability and easy maintenance design ; Backup roll eccentricity compensation ;
Jan 01, 2015· When rolling with automated profile control is introduced at the plate mill, it imposes strict requirements to accuracy of automated gauge control. The structure of the Hydraulic Gap Control .
The mills will be capable of using a large range of workroll diameters, from 37 to 80 mm, in order to achieve efficient and economic rolling performance. The final applications of the highperformance copperalloy strip produced by Ningbo Powerway Alloy Material Co. will be mainly used for aerospace, highspeed trains, solar energy ...
They also include a separate hydraulic unit with hydraulic pump and control panel, hydraulic cylinders to transfer the contact pressure to the rolls, adjustable roll nip pressure between 50bar and 80bar, and a safety function that causes rolls to disengage when a foreign object passes. Laboratory roll mills for industrial grinding
ABB also replaced Mycron Steel''s force motor valve for cold rolling mill roll gap control with the latest servo valve system. Continuing production with an obsolete automation and drive system is done with great risk of component failure. In this project, ABB made a complete review of the system in
Backing up the roll former can allow you to look for pressure marks, misalignment problems in a radius, or roll stops that are being hit too hard. Using a straight edge on the back side of the roll form tooling will indicate machine face alignment problems and will show if the top roll form tooling is parallel with the bottom roll form tooling.
