【Abstract】 In fluid bed, both particles and carrier gas occur violent turbulence so that the heat transfer and mass transfer in the furnace are speeded. Fluid bed furnaces not only have high heating velocity but also the carburizing period can be 30% shortened than that in traditional furnaces. This paper introduces some design essentials and effects of those furnaces.更多还原
