How the furnace works The fuel is burned in the furnace to release heat, and the heat is transferred to the furnace tube (mainly through radiation heat transfer in the radiation chamber, and mainly through the flue gas convection heat transfer in the convection chamber),Martensitic stainless steel vacuum sintering heat treatment and the heat is transferred through the furnace tube wall to the material in the tube, So as to achieve the purpose of heating the material.Vacuum heat treatment furnace for copper alloys Second, the composition and function of the tubular heating furnace 1. Composition A tubular heating furnace is generally composed of four parts: a burner, a radiation chamber, a convection chamber and a chimney. Furnace tubes are installed in the radiation chamber and convection chamber; burners are installed at the bottom, side walls or top of the radiation chamber; flue baffles are installed in the chimney. Advanced furnaces are also equipped with air and fuel ratio control and regulation systems.Martensitic stainless steel vacuum sintering heat treatment
