Prof. Sanjay Chandra teaches Modelling of Metallurgical Process to postgraduate students and Plant Engineering (a course that illustrates the workings of a manufacturing unit) to dual degree students. He shares the responsibility of Mechanical Testing laboratory (undergraduate) and computational lab (post graduate) with his colleagues. The thrust of the teaching is to bring in computation and quantification to metallurgical processes.
Prof. Sanjay Chandra’s research interest has been in the area of modelling of metallurgical processes for a steel plant. He has worked on heat transfer and solidification of billets during continuous casting and the design of model tapers that derives from it[1]. New insights into the interplay of mould tapers around the meniscus region and the solidfying steel shell could be gleaned from a combination of mathematical models and plant trials with instrumented billet moulds. Development of a coupled phase transformation and heat transfer during cooling of high carbon wire rods has been used extensively at Tata Steel for quality control as well as upgradation of the wire rod mill[2]. This modelling work also revealed the inade quacies of the Continuous Cooling Transformation (CCT) diagram for predicting phase transformation kinetics during nonisothermal processes. This is of particular importance as the CCT diagrams are often touted to be useful for, and used in, industrial processes. Modelling of cored wire injection into a steel ladle done to optimise the injection parameters for improved alloy recovery during wire injection has been used to set the injection parameters at Tata Steel[3]. This has been able to link the recovery of Calcium, Aluminium to the grade of steel, thickness and carbon content of the casing, wire speed amongst other injection related variables. Currently Prof. Chandra is working on prediction of cutedge corrosion protection of coated steel sheets and recrystallisation kinetics in low carbon steel using a combination of experiments, numerical
