Title: Design and Applied Research of the continuous type heats metallurgical furnace with gas mixture
ABSTRACT
The continuous type heats furnace is an important craft to produce one of the equipmentses in the steel rolling profession.
The paper started on the industry stove's history, present's condition and its development direction has made the statement, emphatically to industry stove's structure as well as industry stove's operating duty, energy conservation technical change and “three high one low” theory introduction, then to the industry stove's supplementary equipment and the burner nozzle, the heat interchanger, the chimney and so on related structure and selected carries on the analysis statement. Then pushes the steel type heating furnace's design calculation, including fuel combustion,the billet heating time,the furnace to determine the basic size,the heat balance calculation and the determination of fuel consumption,smoke extraction system calculation. This article designs the heating furnace is the triad pushes the steel heating furnace. It is divided into three parts, and warm for a period of heating period, for a long, hot for a period of time. It has manifested “three high one low” the theory in the design parameter choice, and carries on the narration to this heating furnace some technologies and the economic indicator.
Rotary hearth furnace using natural coke oven gas as main fuel。Rotary hearth furnace of this design approach of mechanical smoke exhaust. Stove smoke extraction system as a result of greater resistance, so the use of direct smoke smoke smoke form. Smoke extraction system in the design, the main resistance to the flue, the chimney of the calculation, the calculation of the resistance furnace, cooler-doped smoke machine selection and the selection and so on.
