Abstract
PURPOSE: To develop a heating furnace with easy taking in and out operation of cast metal as well as reduced obstacles by providing five or more of taking in and out openings of which a cross area is 1/5 or less of a roof cross area in a roof portion of a hot blast heating furnace heating cast metal or the like.
CONSTITUTION: To one end of the hot blast heating furnace 1, an outlet 6 is provided in an opposed side of a hot blast inlet 5 and, moreover, five or more of taking in and out openings 2 for taking in and out cast metal 4 are provided in a furnace roof. The cross area of the taking in and out openings is limited to 1/5 or less of a roof cross area and closable covers 3 are attached to each openings. When a metal 4 to be heated is taken in and out a heating furnace 1, because covers 3 are opened and the taking in and out operation is carried out by a crane provided out a heating furnace, the said operation is easy and, because movable portions such as a conveyer apparatus for supplying a metal to be heated into a furnace are reduced, obstacles are reduced. Moreover, because a size of a taking in and opening is small, the heat loss from these openings is reduced.
