Synopsis  : 

This paper presents a reliability analysis of a continuous casting (CC) steel plant. The CC plant under consideration is operating round the clock. Two years breakdown data of a CC plant for four critical equipments viz. ladle handling crane 01, 02 and billet handling crane 01, 02 have been used for the purpose. Any one equipment failure brings the CC plant to a complete halt and stops the production. The critical equipment fails due to any one of the five types of failure as categorized in the data. The paper outlines the complete reliability analysis of the plant and measures of system effectiveness such as the busy period of repairman for all types of repair, replacement, reconditioning and reinstallation, expected number of replacements, expected number of reconditioning and reinstallation, are obtained by using semi-Markov processes, and regenerative point techniques. Total profit incurred to the system is also evaluated. Related graphs are plotted to interpret the results.
