It takes a very important position in the production of various industrial sectors. As Chineses socialist market economic system establishment and constant improvement, Chineses industrial develop rapidely. Metal heating areas has larger changes in the structure of industrial furnace. Materials of building furnace, fuel type, heating method and bustion systems and thermal control are linked to environmental protection closely. Today39。s industrial furnace is a major energyconsuming industries. energy conservation and environmental protection have bee the key of the development of industrial furnaces. The main purpose of heating the metal is to improve the plasticity of metal for pressure processing. In accordance with the temperature distribution along the direction of the furnace, which is divided into preheating paragraph, heating and soaking paragraph. preheating paragraph is above preindustrial furnace above the nonheating at the feed end. It use the waste heat to preheat the bustion products of materials. heating section for heating segment, with the bustion zone can increase the temperature to the heating materials. Soaking the material reduce the temperature difference between sections to ensure the quality of heating at end of paragraph. Burning of materials is to meet the conditions to shorten the annealing time in order to enhance the output of the entire furnace. The main ponents of Industrial furnace are masonry industrial 沈陽化工學(xué)院學(xué)士學(xué) 位論文 abstract furnace industrial furnace exhaust systems, industrial furnace and industrial furnace preheater bustion devices. There are several types of industrial furnaces in machinery industrial. Such as in the foundry, there are towering metal melting furnace, induction furnace, resistance furnace, electric arc furnace, vacuum furnaces, open hearth furnace, crucible furnace. And it include sand drying furnace, oven and cast iron alloy furnace for baking sand. In the fing shop, there are the steel ingot or billet for fing a variety of preheating furnace and postfing heat treatment furnace to eliminate stress. In metal heat treatment plant, it used to improve the mechanical properties of a variety of workpiece annealing, normalizing, quenching and tempering heat treatment furnace. There are sintered metal the furnace in powder metallurgy sintered metal workshops. Said the general habits of industrial furnaces by more luck pushing steel materials for Pushertype Reheating Furnace, Pushertype furnace is the most mon iron and steel enterprises furnace. In order to design a furnace that can save energy and has high dfficiency domestic and foreign advanced experience co mbined with the actual production of iron and steel enterprises are refered. I have pleted the design of the graduate. According to the types of fuels ,metals size and the heating temperature, the use of experience and a bination of given data to determine the thermal furnace system, the expected length and effective manner. In order to remove material in the heating section of the bottom water slide and India have, it is set in soaking paragraph in the rear of the stove to reducing the temperature difference between sections at the same time. The design drew on the experience that are accumulated by our predecessors. Advanced bustion technology, reasonable structure of 沈陽化工學(xué)院學(xué)士學(xué) 位論文 abstract the lining, extraction systems and automatic control system are used. It bined with some of today39。s advanced process technology. Eombined with the requirements of the subject, I design the continuous furnace. The furnace achieves a simple Control and convenient. The dissertation of the design makes an analyse of blast furnace of provision and avoid it introduce furnace running and shutdown with a brief introduction before the operation, so we have a general understanding of operation of industrial furnaces. After learning the basic theory of the furnace and the actual design process, I understand the selection and application of the continuous heating furnace, which will lay a good foundation for my future work. Keywords: furnace。 metal heating。
