A typical SRM is composed of a series of three-roll grooved stands arranged closely behind each other and at 60° displacement relative to the preceding one (Figure 1), the change of the tube diameter being predetermined by the pass series used. During the
Stretch-reducing rolling mill operation method and stretch,
The invention relates to a method of operation for reducing stretch-reducing rolling mill for rolling tubes of finite length, containing at least two rolling stands, which are located one behind the other in the feed direction of the pipe, with each rolling stands are at least two interacting roll, each of which at a certain peripheral section of pipe attached to it and roll it, and there are at least two drives for two different rolls of the rolling mill.Mills for Reducing Tube Thickness and Sizing | Metallurgy,Stretch Reducing Mill: In stretch reducing no internal mandrel is used. The mill may consist of 24 to 30 stands placed in tandem and tube is rolled continuously through all the stands as shown in Fig. 12.26(a). Each stand has separate speed control system. The modern stretch reducers have three rolls placed symmetrically around the circumference. Figure 12.26(b) shows the arrangement of rolls,Computer Simulation System of Stretch Reducing Mill,,01.12.2007· The principle of the stretch reducing process is analyzed and three models of pass design are established. The simulations are done about variables, such as, stress, strain, the stretches between the stands, the size parameters of the steel tube, and the roll force parameters. According to its product catalogs the system can automatically divide the pass series, formulate the rolling table,Design and application of round pass for stretch reducing,,Article “Design and application of round pass for stretch reducing mill.” Detailed information of the J-GLOBAL is a service based on the concept of Linking, Expanding, and Sparking, linking science and technology information which hitherto stood alone to support the generation of ideas.

Design Dust Pelletizing System for Sizing Mill and Stretch Reducing Mill of Seamless Tube Plant of Baotou Steel @article{Ji2015DesignDP, title={Design Dust Pelletizing System for Sizing Mill and Stretch Reducing Mill of Seamless Tube Plant of Baotou Steel}, author={L. Ji}, journal={Science and Technology of Baotou Steel}, year={2015} }Numerical Design of a Hot-stretch-reducing Process for,,During stretch reducing, steel is submitted to complex stressing and straining processes. This paper gives a theoretical model of a heat- stretch-reducing precess for the relation between the tube diameter and the wall thickness. The design is verified by a determination of the number of revolutions of rolls with every caliber for specific tubes on an industrial mill.
