John G. Lenard, in Primer on Flat Rolling (Second Edition), 2014. 3.5 Friction and Wear. Work rolls in hot strip mills wear due to friction between the roll surface and hot strip. (Back-up rolls wear as well, but under pressure with elastic deformation, the friction is much less, except for the high work roll roughness in the last stand of a sheet rolling tandem cold mill).
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 .
At today's demanding condition, maintaining stable operation of rolling mill is becoming difficult. MSD is a hydraulic cylinder installed to mill housing window and press a roll chock against the opposite side with constant force. MSD eliminates gap between roll chocks and mill housing, keep rolls in proper position and stabilize rolls.
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 gas-fired furnaces that have a hearth dimension of about 13 metres by 30 metres. In a pusher-type furnace, the slabs slide on water-cooled ...
The mills will be capable of using a large range of work-roll diameters, from 37 to 80 mm, in order to achieve efficient and economic rolling performance. The final applications of the high-performance copper-alloy strip produced by Ningbo Powerway Alloy Material Co. will be mainly used for aerospace, high-speed trains, solar energy ...
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 ...
As 8 A 1. hydraulic fluid dirty 2. hydraulic fluid s 1. Stick-slip effect due to the friction of the cylinder packings being too high. 2. operating below lower limit of motor speed insufficient load counter-balance (e.g. lowering control valve) D Power Take-off either does not turn at all, or - .
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

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, .
Hot Rolling Mills. 54/154. Processes & technologies; Technological packages; HAGC. Hydraulic automatic gauge control. BENEFITS. Fast-response thickness control ; High-accuracy gap positioning ; Smaller thickness tolerances and faster thickness correction ; Reliability and easy maintenance design ; Back-up roll eccentricity compensation ;
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 flat--if 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 ...
A roll configuration that extends the working gauge range of the leveler without requiring roll cassette changes or two separate levelers; Inter-roll tension control that provides tension between every work roll; Independent entry/exit work roll bending; A proprietary roll configuration that covers up .
18 Roll Hydraulic Rolling Mill There are two types of 18-roll hydraulic rolling mill—-Z-high type and S-high 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 non-ferrous metal strips.
Aug 16, 2015· Two-Roll Rubber Mixing Mill Selection Questionnaire 1. Two-Roll Mill Selection Questionnaire Page 1 of 4 QUESTIONNAIRE FOR 2-ROLL MILL REQUIREMENT Criterion Please Answer Descriptively if needed Production Requirement: _____ Tons/Hour ; _____ of 8 hour Shifts/Day What is your expectation from this Mill?
Hydraulic gap controls, with mill steer and roll eccentricity compensation. • Work roll chock mounted scratch brushes. • Fast work roll change. • Adaptive and predictive process control technology using temperature sensors and profile and thickness gauges. • Efficient spray control systems providing high-resolution thermal control of ...
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.
Hydraulic oil level low. Hydraulic oil level low - pumps stopping. Determine what is causing the drop in oil level. Add clean oil. The pumps will stop automatically if the level drops to the shutdown level. Pump fault MCC or standby pump fault MCC (identified by pump) Motor output gives alarm to control desk if that pump is not running.
Either the work roll or the back-up roll is driven, depending on customer requirements. The diameter of the 4-high 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 ...

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 X-Ray thickness gauge in the last pass. This measurement is possible within several meters distance from the
