CONTINUOUS STEEL HEATING FURNACE FEATURING FREE SETTING OF AN IN-FURNACETEMPERATURE PATTERN

摘要

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