This paper presents a design for the temperature distribution of a continuous furnace system.The furnace was used in sintering applications for powder metallurgy products. The following design also includes heating systems, insulation systems, and material handling. Temperature analysis was focused on temperature distribution on sintering sample. The temperature distribution was also analyzed based on the material layout during the sintering process. All results were based on heat transfer, confirmed by ANSYS software.The dimension of the CF for application of P/M production is (L x W x H): 3 x 500 x 500 x 360 mm 3 with the length ( feed zone, pre-sinter zone, sinter zone, post-sinter zone dan discharge zone) was 500 mm and length of cooling zone is 1440 mm. The material production rate was 874 material/hour. The heating system uses kanthal AF with diameter of 1,6 mm, length of heating element 3,4 m, total power of 30 kW, voltage of 220 V, and total current 135 A. Insulation system uses composite wall with insulating brick (11 cm thickness) and ceramic fiber blanket (5 mm thickness). The material handling system uses mesh belt conveyor from material SS314 with length of 4190 mm, width of 356 mm, and conveyor speed of 0,277 mm/s. The standard temperature for pre-sinter zone is 225 °C while the design obtained 210.44 °C and sinter zone is 300 °C while the design obtained 293.52 °C. The results showed that the optimum zone temperature in the pre-sintered (225 °C) and sintered zones (300 °C) are 210.44 °C and 293.52 0 C, respectively. Validation of heat balance shows that the deviation was minimal and can be ignored, thus the design is considered the most suitable.
