| Abstract | This research has developed a Nam Phi iron ore smelter with a combination of traditional method and modern technology (mix method). Smelter center was designed as refractory bricks. Its walls were plastered by mixing natural clay and local materials, such as husk, sand and water. Steel pipes from the blower were connected to the combustion chamber. It took three days to dry the smelter. The strength of smelter's walls is tested via Rebound Hammer Test machine. The strength was 109.65 kg/cm2 before smelting. The smelting used 20 kg of Nam Phi iron ore, resulting in 2.3 kg of formed Nam Phi iron rods. Then the Test Pieces were fabricated for Vickers Hardness Test (HV) which included the Test Piece Group A and Test Piece Group B. For hardness value, it could be found that the average hardness value of Group A (105.67 HV) was higher than the value of Group B (100.30 HV). Microstructure of samples were determined using scanning electron microscope technique. The SEM micrographs showed that the combination of ferrites and pearlite structure was observed. And the microhardness of each sample showed that average microhardness of Group A was 102.2 HMV and 146.9 HMV for the white and black stripes, respectively. For Group B, it was found that the average microhardness value of white stripes was 123.2 HMV whereas the value of black stripes was 107.9. Thus, it could be concluded that mechanical properties of Nam Phi iron was improved with the new mixed method fabrication. |
