P. O. Oghenerukevwe, A. O. Emu "Development and Performance Evaluation of Indirect Resistance Furnace", International Journal of Engineering Trends and Technology (IJETT), V53(2),100-103 November 2017. ISSN:2231-5381. published by seventh sense research group

An indirect resistance furnace was developed and constructed to melt approximately 40kg of steel/cast iron scraps. In the design, efficiency of heat utilization as well as ease of operation and maintenance of the furnace was primarily considered, among other things. Materials selection and design details were aimed at ensuring reliability of the furnace. Value analysis method was employed in the selection of materials while mathematical modelling approach was employed in design calculations cum analysis. Test carried out showed that it required about 70 minutes to heat up the furnace to the melting temperature of cast iron (11500C – 14000C). It took about 95minutes to melt the first charge of 5kg resulting in a melting rate of 52.63g/minute.
