一、前言锻造加热炉是锻造行业的关键设备之一,并拥有相当的数量,仅上海地区就有各类锻造加热炉2000余台,其中90％是中小型锻造加热炉。长期以来一直没有引起足够重视,从而造成相同锻造设备的加热炉结构形式,规格尺寸比较混乱,导致加热炉能耗高、热效率低、寿命短、外观差、污染严重的状况。为了改变这种落后面貌,我厂86年经上海市经委,科委立题“优化研制中小型煤气锻造加热炉系列”,针对上述问题,首先对中小型锻造加热炉的结构、规格、定型进行了广泛的调研及系列化、标准化工作,在设计中采用了贯通式半连续加热炉型,设有加 I. Introduction Forging furnace is one of the key equipment forging industry, and has a considerable number, only there are various types of forging furnace in Shanghai, more than 2000 units, of which 90% are small and medium-sized forging furnace. For a long time, it has not given enough attention, resulting in the same form of furnace forging equipment structure, size and specifications more chaotic, leading to high energy consumption furnace, low thermal efficiency, short life expectancy, poor appearance, serious pollution. In order to change this backwardness, in our factory 86 years ago, Shanghai Economic Committee and Science and Technology Commission set the theme of “optimizing the development of small and medium-sized gas forging furnace series”. In response to the above problems, the structure, specifications and stereotypes of small and medium- A wide range of research and serialization, standardization work, adopted in the design of semi-continuous through-type furnace, with Canada
