引言烧矿物燃料的熔铝炉和保温炉,传统上是通过辐射向金属传热的.当用长焰烧嘴加热炉墙和炉顶时,炉子达到辐射式传热.然后,升至1150℃-1430℃的耐火材料把热量辐射到它所能“见”着的铝上,可惜只有不多的铝“见”着炉墙和炉顶.另一方面,铝吸收的热量也不多,因为它是热辐射的良好 Introduction Fusing furnaces and holding furnaces for burning fossil fuels traditionally transfer heat to the metal by radiation. When the furnace walls and roofs are heated with a long flame burner, the furnace reaches radiant heat transfer and then rises to 1150 ° C Refractory at -1430 ° C radiates heat to the aluminum it “sees”, but only a small percentage of aluminum “sees” the furnace wall and roof. On the other hand, aluminum absorbs less heat because It is good for heat radiation
