Gas Atomizer Making to Produce Tin Powders

Article Preview

Abstract:

The objective of this research is to make an economical laboratory-scale, horizontal gas atomizer for producing tin powders. The procedures were designing a furnace, gas chamber and cyclone, and 2-nozzle air tubes. All equipments were built and assembled to be a gas atomizer. The gas atomizer was trial run by blowing nitrogen gas to molten tins. It produced powders in many sizes. The trial run had been repeated in many conditions. The variable conditions were the molten tin temperature, the 2-nozzle air tubes angle, and the gas pressure. The best trial run resulted, tin powder smaller than 150 μm was 75.4 %. The best conditions of trial run result were 300 o C of molten tin temperature, 30 degree of 2-nozzle air tubes angle, and 200 psi of gas pressure. The tin powder particles were spherical shape. This research can produce an economical laboratory-scale, horizontal gas atomizer for learning metal powder.
