In rolling mill stands for rolling steel and nonferrous metals, it is known in the art to adjust the work rolls,, usually the upper roll and the lower roll, by means of hydraulic adjusting cylinders. The adjustment results in a change of the width of the roll gap and in a change of the rolling force.
As shown in Figure 1: the adjustment mode that adopts stepless hydraulic cylinder jacking, this adjusting device mainly comprises underneath type AGC1, roll change balladeur train 2 and horizontal pushandpull hydraulic cylinder 3, lower support pad 4 is allinonepiece downstairs pad, when the height of roll line is regulated in roll 5 wearing and tearing backs, AGC1 and roll change
the setting and adjustment of roll gap or rolling pressure. In terms of control function, a complete HAGC system is composed of several automatic control systems. The most important three control loops are as follows: cylinder position closed loop, rolling pressure closed loop and thickness gauge monitoring closed loop, as shown in Figure1.
mill housing HGC cylinder upper backup roll upper work roll lower work roll lower backup roll Fig. 2. Side view of the mill stand with the HGC cylinder adjusting the height of the roll gap by moving the upper roll stack. on the difference of the measured forces at the DS and OS, see,, [11]. Recent developments track the lateral strip position
#0183;#32;The hydraulic adjustment forces exerted by the adjuster cylinders should be as great as possible during rolling, and in any case greater than what is required for balancing the weight of the frame caps together with the upper roll or the upper roll set in order that the oil film between the screw threads of the screwdown device is forced out and the yield under pressure can be held as small as
These cylinders are employed extensively in the metals industry for rolling mill applications. The design of the rotating cylinder enables lateral shifting to hold the mandrill tight against the inside of a coil, while the mandrill and cylinder rotate at very high speed. Specifications: Bores:
The dynamic behavior of rolling mill''s gap adjustment system is mainly depends on the correct operation of hydraulic capsules and servo valves. For this reason, the hydraulic cylinder must be
hydraulic cylinder for lateral adjustment of mill roll stand,Our company is a largescale heavy enterprise that taking heavy mining machinery manufactory as main products and integrated with scientific research, production, and marketing. We are concentrating on producing and selling machines such as jaw crusher, cone crusher, hammer crusher, ball mill, sand maker, mobile crushing plant
#0183;#32;The rolling mill stand defined in claim 4 wherein said upper roll and said lower roll are braced by respective pluralities of lateral intermediate rolls and respective wedges, at least a lower one of said wedges having a slidable fitting piece received in a guide groove of the respective supporting beam, upper and lower wedges also being provided upstream of said upper and lower rolls for
The present invention involves the installation of commercially available hydraulic cylinders within backup roll chocks of a rolling mill stand and the use of such cylinders to provide sufficient horizontal thrust from the cylinder plungers to eliminate any gapping between the cylindercontaining chock and the inner wall of its mill stand housing, thus preventing vibrational chatter.
Hydraulic Cylinder For Lateral Adjustment Of Mill Roll Stand. Magadh can supply 20hi mills for strip width up to 1625 mm minimum finish strip thickness up to mm and mill speeds up to 800 MPM which are quite popular for rolling high tensile ferrous and nonferrous metal strips especially of wider width to thinner gauges more effectively than other mill
In order to facilitate packer interchange, in a rolling mill stand comprising a pair of spaced housings having windows therein to receive bearing chocks of rolling mill rolls, and roll gap adjustment means carried by each housing to act between the top of the housing and the uppermost roll, the present invention provides sledge means movable between an inoperative position outside the housings
We claim: 1. In an arrangement for adjusting a roll gap in a rolling mill stand for hot or cold rolling, the arrangement including at least two hydraulic adjusting cylinders which act through chocks from both sides on a work roll to be adjusted, each adjusting cylinder having two or more piston surfaces, and including means for applying pressure medium to one of the piston surfaces
