Guillotine side trimming shear machine: A case study of plate mill in Bhilai steel plant

Abstract: Article history: Received 6 October, 2015 Accepted 23 April 2016 Available online 24 April 2016 Double-sided trimming shear machine is used for longitudinal both–sided trimming of steel plates and simultaneous scraping of trimmed edges at specific length. Side trimming shear (STS) executes the most vital role in increasing the productivity of plate mill and due to its feature, efficiency of plate mill division is enormously increases. In general, frequency of the occurrence of breakdown in STS machine is a most challenging task when STS performs side trimming and scrap cutting machining process. Bhilai Steel Plant (Steel Authority of India at Bhilai) in India is continuously facing a problem due to breakdown of STS machine. The use of separate knife for side trimming and scrap cutting reduces the possibility of scrap jamming which is a major reason for breakdown of STS machine. Researchers and practitioners also suggest the use of arc guillotine shear for side trimming and straight guillotine shear for scrap cutting for minimizing the breakdown in STS machine. The aim of this study is to describe the problems faced by the steel industry as well as the necessary steps which should be taken for improvement of the productivity of STS machine and also it has made contribution to Bhilai Steel Plant by its growth and prosperity. The methodology of study is purely qualitative and the results point out the problems, its implications, steps taken to improve the overall productivity of Bhilai steel plant. © 2016 Growing Science Ltd.

Ultrasonic testing for mechanical engineering domain: present and future perspective

Abstract: Ultrasonic testing uses high frequency sound waves of a range between 0.5 to 15 MHz to conduct testing. The basic principle and applications of ultrasonic testing techniques is enormous use under the domain of mechanical engineering applications. Importance of ultrasonic testing of rails, train wheels, carbon fiber reinforced plastic, aeronautical defects in composite structures, testing of welds, and some other applications are increasing day by day. Literature survey reveals that it is a challenging task for practitioners and researchers to increase the efficiency of non-destructive testing techniques for identifying and localization defects in different mechanical engineering components/parts. Basic fundamentals applications of ultrasonic testing of metal, non-metal, ceramics, polymers, concrete, etc. are briefly explained. Present and future perspective of ultrasonic testing for mechanical engineering domain are discussed along with the sub new development in the area of ultrasonic testing.

Iron and Steel Industry in India

Abstract: This paper analyses the Iron and Steel Industry in India post 1991 reforms. The approach is completely statistical as I use the ASI and CMIE data to explain the development of this sector. I also analyse company wise data and report the major players and their performance over the years.

The compensation study on blade gap during shearing process for swing shearing machine

Abstract: The static analysis has been executed to swing shearing machine through ANSYS Workbench in the text. The deformation volume of the swing shearing machine during cutting process has been obtained, as well as the change of blade gap. The workbench structure of swing shearing machine has been optimized by use of ANSYS Workbench method, which can compensate the blade deformation and blade gap.
