摘要： The hot air ladle preheat station comprises an outer casing defining an opening for receiving a separately supported ladle. The opening is dimensioned so as to form a dilution air space about the ladle exterior. A wall is spaced inward of the outer casing and defines a space therebetween having a lower section for accommodating the ladle in spaced apart relationship from the wall and an upper flue section. Stack means are positioned for exiting flue gas from the upper flue section. A burner means is associated with the wall in the lower section for directing a flame into the ladle and a recuperator means cooperates with the upper flue section. Products of combustion are directed into the ladle and exit from the ladle in the space formed with the wall. The products of combustion mix with and are cooled by the outside air entering through the dilution air space and the mixture thus formed passes through the recuperator in heat exchange relationship with combustion sustaining gas utilized in the burner means.
