Design of the Step-by-step Heating Furnace
Abstract: Metallurgical furnace heat processing means, not only the heating equipment when the metal is heated to rolling, extrusion or forging temperature, but also the essential equipment for thermal in the production of industry in China.
This design is based on the Heat Transfer, Engineering Thermo dynamics, Flame Furnace and other course, and referred to a large number of furnace design information for the overall design of the furnace. This thesis according to a four-year study of the professional theoretical knowledge at the University and many scientific and technical literature data and with the help of teachers designs the step-by-step heating furnace. The design includes literature review, thermal calculation, metal heating calculation, the determine to the furnace main dimensions, furnace heat balance and fuel consumed, the choice of the gas burner, heat exchanger design and calculation, air lines pressure drop calculation and air blower choice, flue resistance loss and the chimney calculation, the English translation of the literature and others. Finally, the CAD software is used to draw the whole body of the furnace. 源`自*六)维[论*文'网www.lwfree.cn
