Fundamentals of Roll Cooling and Control of Flatness at

In the process of Rolling the most significant aspect is the generation of heat through friction and deformation in the roll bite and in a typical Cold Tandem Mill, work roll temperatures normally fall in the range of 55oC70oC with strip recoil temperatures and inter-stand strip temperature rarely exceeding 160 oC depending on product.

presented. In Section 5, thickness control with roll ec-centricity compensation has been proposed. In Section 6, simulation results have been presented. Finally, section 7 presents the conclusions. 2. Cold Rolling Process Overview . The tandem cold rolling of metal strip is one process in a sequence of processes performed to convert raw mate-

Cold Rolling Mills. From a new single stand reversing cold mill to a complete revamp of a multi-stand mill, Butech Bliss delivers. We specialize in the evaluation of existing mill stands and the necessary reconditioning of the same for use in other applications.

The development of the theory of metal rolling and its

mill and control must be based. Rolling theory can be divided into two broad and general cate- gories, that which applies to hotrolling and that which applies to cold rolling. In hotrolling the yield stress characteristic of the metal is strain -rate dependent and frictional force between the roll and stock is high.

Analysis of symmetrical flatness actuator efficiencies for

Mar 11, 2017 · As the basis for a flatness control system, flatness actuator efficiency describes an actuator’s control ability, but it is difficult to obtain an actuator efficiency factor accurately through rolling tests because of the complicated subsidiary facilities of the mill. This paper proposes a novel simulation approach that is applied to obtain the actuator efficiency factors in terms of work

Cold Rollingan overview ScienceDirect Topics

For cold rolling the strain hardening of aluminium alloys is an important aspect in processing control and sheet properties (see Chapter 11 of this book). For (technically) pure aluminium and some typical non-heat treatable Al-Mg-Mn sheet alloys, the flow stress evolution (i.e. strain hardening) is shown in Fig. 23.10 as function of cold rolling strain up to high rolling strains (90% reduction).

Rolling Millan overview ScienceDirect Topics

A reversing, single-stand, cold reduction mill can be considered similar to the first stand of a tandem mill. Without instrumental control a great deal of skill is required to achieve uniform lateral and longitudinal thickness using a combination of screw-down on the reducing rollers and tension between the reducing rollers and the wind-on reel.

GENERAL ASPECTS OF ROLL COOLING FOR HOT & COLD

rolling mill, dedicated roll cooling systems are required to fulfill the required functions. Examples are suitable roll cooling and lubricationsystems to fully utilize the advantages of HSS rolls in hot strip mills, and selective roll cooling systems as a method to control the flatness of the strip in cold rolling mills.

Research on Broken Edge Wave Control Strategy Caused by

Taking MH UCMW cold tandem mill as research object, broken edge wave generating mechanism and characteristics were analyzed which caused by edge drop control. Based on original control strategy, an automatic edge wave control model was developed, and edge drop control strategy was optimized. Effect of taper work roll shifting and taper shape on broken edge wave were analyzed by actual rolling
