<p>A non-oxidizing heating method and an apparatus therefor, in which a non-oxidizing gas of high temperature is continuously produced and supplied into a furnace while operations are repeated such that a plurality of regenerative heaters are alternately changed over to perform heat reserve by one of the regenerative heaters and heat a non-oxidizing gas by the other of the regenerative heaters for blasting. Since heating can be effected with an interior of the furnace being in a completely non-oxidizing atmosphere, the non-oxidizing heating method and the apparatus therefor can be effectively applied to furnaces, which need heating in a non-oxidizing atmosphere, for example, various furnaces used in steel making and continuous casting fields, such as a ladle and a tundish, and various furnaces used in heating and heat treatment fields for metallic materials, to be effective in reduction of operating cost, improvement of product quality, enhancement of yield of products and the like.</p> |
