Abstract: The resistance heating (RH) is the heating process by which the passage of an electric current through a conductor produces heat which also known as Joule Heating or Ohmic Heating. The efficiency of RH process can be affected by its parameters such as heating temperature, heating time, etc. which depends on the types of steel used. For instance, insufficient heating time and heating temperature or vice versa actually will lead to defect of spring steel when it applied resistance heating. Up to this date, there is limited study on heating temperature and heating time for RH across different types of steel. The objective of this study is to determine an ideal heating temperature and heating times that will be able to minimize the defects of spring steel products. Hence, this paper presents a study on the dimensional effect of spring steel by heating temperature and heating time through Resistance Heating concept by application of the DOE (Design of Experiment) method. By using DOE method, the heating time and heating temperature setting as independent variables were optimized. Analysis is done using ANOVA to determine the best setting of parameters to provide least dimensional defect on spring steel. Result of the experiments shows the main effect and interaction plot of ANOVA analyses, it is clear that the optimal combination of process parameters is 52 or 54 seconds for heating time and 900 degree Celsius for heating temperature and the optimal level of setting parameters that must be followed during process parameters is 54 seconds for heating time and 900 degree Celsius for heating temperature. In conclusion, result of this study provides an ideal setting of the parameter that is significant to the efficiency of Resistance Heating concept. Furthermore, the findings provide better understanding of parameter settings for Resistance Heating technique.
