Abstract:
The determination of the pressure distribution generated along the arc of contact between the rolls and workpiece during the rolling process has been a subject of interest to researchers for many years. Existing rolling theories make assumptions and include simplifications which are not often substantiated by direct measurement techniques in which pressure transducers are located within the roll surfaces. Such techniques are effective but prohibitively expensive since they render the rolls useless for rolling. A technique has been developed in which the pressure distribution and roll separatin

The objective of this investigation was to determine the influence of work roll cooling on roll thermal behavior. The investigation has been conducted utilizing a previously developed computer model [1]. Three industrial operations were evaluated and features of an optimum configuration have been identified. The magnitude of the thermal zone near the roll surface within which the cyclic temperature variation is confined has been evaluated for different roll cooling conditions. A two dimensional thermal model of a work roll has been developed to predict the thermal field inside the roll, based

Abstract:
This research aims to examine the feasibility of a new concept in section rolling of thick strip, which either could not be rolled at present due to cracking at bent corners. Whereas, the second moment of area of sections could be increased through sharpened corners and increased gauge thickness. A heat assisted section rolling process is proposed. This process is based on application of high intensity heat on the inner surface of the strip, immediately prior to rolling. To investigate the new section rolling concept, the following work has been carried out. Firstly, the material property of t

Abstract:
The steel industry has been producing flat plates through the process of hot rolling since the late 1600s. Hot rolling uses a series of rolls to progressively thin a strip of steel to a desired thickness. In deforming the strip, the rolling process causes variations in thickness across the width of the strip. These variations are commonly referred to as crown, which is specifically the difference in thickness between the center and edge of a strip. For most applications steel mill clients require flat products, or products with little variation in thickness. Therefore, variations represent was

Based on experimental results using hot torsion, the effect of 'time gap', i.e. the time between roughing and finishing in a hot rolling schedule simulation, on mean flow stress (MFS) behavior for high-strength-low-alloyed (HSLA) steels was investigated. Two types of hot deformation were studied: an 'average' schedule with constant interpass time, in which each pass is identical but the temperature is decreasing at a constant rate throughout the rolling schedule simulation. In this type of schedule, two different interpass times of 5 and 30 seconds were used to study the influence of precipita

Asymmetrical conditions occurring during the rolling of hot strip can cause strip curvature and can lead to poor product shape, profile, quality and cause reduced productivity. In the most severe of cases, strip with a head-end turning towards the upper work roll, may fail to enter the roll gap on its next pass and result in ‘a cobble’. Finite element techniques have been used to decouple some of the major causes of strip curvature during the roughing stages of Port Talbot hot strip mill.

碩士<br>國立臺灣科技大學<br>機械工程研究所<br>83<br>This paper explores the distribution of roller elasticthe rolling area during the rolling process, under the assumption of roller and without the consideration for heat conduction. The deformation distribution on the strip surface after rolling was yzed to confirm that a slight protrusion in the surface of the cross section can effectively improve the smoothness of strip In terms of strips, the large deformation-large strain theory, Lagrangian formulation

碩士<br>國立高雄第一科技大學<br>機械與自動化工程所<br>92<br>The target of research is to eliminate the work roll deterioration for strip quality and cost down. Post research has discussed this subject with three control factors. Five control factors together with tribological viewpoints were considered in this research. Taguchi method was used to arrange an experiment, and thus identified the significant factors for Hot Rolling Process. As result of the experiment, the reason for work rolls deterioration that was found to be affected by high temperature at the interfaces of strip and work roll. At the interface
