#CMT# #/CMT# The method for thermally treating ultra-high strength steel materials with inert gas, comprises producing inert gas atmosphere, which influences on a material, in a chamber of a heat treatment furnace by fluidized carbon dust, and introducing the material in the furnace chamber and then subjecting to a thermal treatment. Several nozzles are used for injecting the carbon dust in the furnace chamber and are flowed through by a gas flow, which is supplied to the carbon dust by using a pneumatic conveyor. #CMT# : #/CMT# An independent claim is included for a device for thermally treating materials with inert gas. #CMT#USE : #/CMT# Method for thermally treating ultra-high strength steel materials with inert gas (claimed). #CMT#ADVANTAGE : #/CMT# The method is capable of efficiently and economically treating the ultra-high strength steel materials. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The diagram shows a schematic view of a wall of a heat treatment furnace. 1 : Nozzle tip 2 : External tube 3 : Feed tube 4 : Aperture 5 : Supply 6 : Internal tube. |
