Side trimming shear Accepted 23 April 2016 STS executes the most vital role in increasing the productivity of plate mill and due to its Available online feature efficiency of plate mill division is enormously increases. In general frequency of the 24 April 2016 Keywords occurrence of breakdown in STS machine is a most challenging task when STS performs side Trimming mechanism trimming and scrap cutting machining process. Bhilai Steel Plant Steel Authority of India at Bhilai steel plant Bhilai in India is continuously facing a problem due to breakdown of STS machine. The use Kinematics of machine of separate knife for side trimming and scrap cutting reduces the possibility of scrap jamming Shear force 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 .
