Energy Saving System for Conventional Steel Rolling Heating Furnace
An energy-saving system for conventional steel rolling heating furnace is introduced.The heating furnace adopts a composite lining structure with better insulation effect,which increases the thickness of the insulation layer,reduces the thickness of the working lining,and use plastic to compact the furnace top,reducing heat loss of the furnace body.The heating furnace adopts a reinforced air heat exchanger,which increases the air preheating temperature from the original 450℃to 550℃,fully absorbs the waste heat in the flue gas,and reduces gas consumption.By using intermittent combustion control valves,automatic control of individual start stop of the burner is achieved,which facilitates flexible and timely operation or closure of the burner during heating and cooling of the heating furnace.Combined with pulse combustion temperature control technology,gas consumption is reduced while ensuring flame stiffness.And three closed fire walls are installed inside the furnace to form eddy currents at the lower wall of the heating furnace,thereby forming secondary convection to heat the steel billet,greatly reducing the direct loss of heat.
