ABSTRACT:
A vertical strip heating furnace includes at least two vertical direct fired heating chambers which are arranged in parallel which are communicated with each other. A separation chamber for housing inside furnace rolls at adjacent pairs of the chambers is provided in at least one location. The inside furnace rolls are separated from the main flow of the combustion gases and the temperature of the atmosphere in the chambers housing the inside furnace rolls is adjusted to within a fixed range. This strip heating furnace is capable of large capacity processing and is designed to save energy, and the inside furnace rolls are free from breakage due to thermal stress.
