A crucible furnace is developed continuously to obtain appropriate furnace in support casting practice at VHS. This research aimed at improving performance of compact crucible furnace by modification the heating chamber. Fins were placed at inner side of compact crucible furnace wall. The furnace performance determined by increasing of temperature rate to melt 3 kg of aluminium. Descriptive analysis is used to describe performance of modified compact crucible furnace. The fins addition on the inside wall improves the compact crucible furnace performance. The temperature rate is increase as the fins inclination angle increase. Fins with inclination angle of 800 could keep and maintain the temperature of heating chamber. Compact crucible furnace which added fin on the inside wall is able to melt 3 kg of aluminium in 35 minutes. © Published under licence by IOP Publishing Ltd.
