When use the TM sand, the effect of formed mold is not quite ideal and the overflow of adhesive will also affect the size and quality [35]. In SM, the foundry sand with round grain shape is preferred to reduce the milling damage to the processing surface and tool wear, better the gradations with the particle size of 50/100 and 70/140 mm.

All the materials needed for smelting — charcoal, iron ore, and sand — were bought from stores and suppliers. The process works this way: a fire is lit in the furnace opening at the bottom, and charcoal and iron ore are layered into the top of the tube. As the charcoal burns, it reduces the ore to iron.

year, Kodama et al. [] reported the smelting of iron sand 7 in a small blast furnace and concluded that it was dicult to smelt iron sand only in a furnace because of the high vis-cosity of molten pig iron, unless the iron sand is mixed with other iron oxide source at 1:1 ratio. * Imam Santoso [email protected]
