ABSTRACT:
The present invention relates to a steel heating furnace which permits free setting of an in-furnace temperature pattern or gradient as desired. A steel heating furnace 1 includes at least one or more burner systems of regenerative heating, each being arranged to supply a combustion air and exhaust a combustion gas through a regenerative bed. Those burner systems are disposed in each of plural zones which are defined within a single furnace body, or in each of unit furnaces 2. The unit furnaces 2 are interconnected to form a single furnace body. The amount of combustion may be controlled for each zones or each unit furnaces 2 to enable free variation of in-furnace temperature per zone or per unit furnace 2 so that a desired in-furnace temperature pattern gradient in the entire furnace 1 may be set easily. The steel heating furnace 1 may be constructed with a required length and in-furnace temperature pattern, by interconnecting the unit furnaces.
