Optimization of Hardening Process in Furnace through Taguchi Method

Heat treatment is the process of control heating and cooling of material to achieve certain mechanical property such as hardness strength, and reduction of residual stresses. Many heat treating processes require the precise control temperature over the heating cycle the research methodology based on the experimental work and the theoretical development of heat treatment furnace the new model take into account the real time furnace parameters determined from the experimental data account for the furnace detoriation and some of complex gradient and heating pattern that exist the furnace that is difficult model. Investigation carried out to study increasing hardness mechanical property of mild steel. Sample examined after heating at a certain respective temperature and soaked for respective time and respective behavior on sampled investigated. Using Rockwell hardness method of hardness testing. Results show that hardness of cast iron improved by heat treatment for particular application & optimization of hardness using taguchi method done in this article.
