Subir Biswas is currently Head of the Department at Refractory Technology Group in Tata Steel Limited, Jamshedpur, India.  After completion of B.Tech from College of Ceramic Technology, Kolkata, under University of Calcutta in the year 1985, he was employed in M/S. Carborundum Universal Limited (CUMI), Chennai, India. In CUMI, he worked in Research and Development of Refractory division for ten years. In his tenure in CUMI, he earned in-depth experience in micro-structural analysis on nanoparticles, characterization and fabrication of ceramic foam filters for automobile application.  He successfully completed the projects and developed non-oxide based Si3N4 bonded SiC refractory, SiC based ramming masses for Blast Furnace application, low cement castable and ultralow cement castable to maiden use in Indian industry as an import substation. He was involved in development of Cordierite refractory for energy efficient kiln furniture. He joined Tata Steel in 1996in Refractory Technology Group under Tata Steel R&D and Scientific Services. He has worked in Refractory Maintenance department, Blast Furnace & Iron making area and leading refractory maintenance team. He earned experience in refractory material selection and application in the area of Iron & Steel making. During working in Blast furnace, leaded refractory team in relining of Blast furnaces, and earned experience over 8 numbers of furnace relining. Other contributions are development of tap-hole clay for large blast furnaces through a joint project with TRL Krosaki and NIT Rourkela. He worked in steel making and mills refractory maintenance in different levels of responsibilities and in the year 2009, was promoted to Head  of Refractory Technology Group, the position he is presently holding. He is involved in different collaborative projects with NIT -Rourkela, TRL -Krosaki and other reputed Global refractory suppliers. A few of his achievements include: Dolomite - C refractory
