合理利用燃料、研究和实际采取生产工艺过程中节约燃料的措施是一个有着国家意义的任务。铁路运输部门有许多工厂,这些工厂装备着大量的各种结构的消耗能源的金属加热和热处理设备。例如,交通部机车车辆修理和备品生产总局所属各工厂采用各种火焰炉,感应加热装置和接触式加热装置来进行热塑性成形前金属的加热。加热方式的选择由具体生产条件来决定,并取决于一系列工艺和经济因素,其中包括生产特点,以后加工时对金属表面的要求,毛坯形状,载能体成本。此外,火焰炉的特点是依其用途、燃料种类、加工制度和温度制度、结构形式而采用形式繁多的加热设备。大量生产中所用
Rational use of fuel, research and practical measures to save fuel in the production process is a nationally important task. There are many factories in the rail transport department that are equipped with a large number of energy-consuming metal heating and heat treatment equipment of various structures. For example, various factories owned by the Department of Locomotive and Rolling Stock Repair and Spares Department of the Ministry of Transportation employ various flame furnaces, induction heating devices and contact heating devices to heat the metal before the thermoplastic forming. The choice of heating method is dictated by the specific manufacturing conditions and depends on a number of technological and economic factors, including the characteristics of the production, the requirements on the metal surface after processing, the shape of the blank, and the cost of the carrier. In addition, the characteristics of the flame furnace is based on its use, fuel types, processing systems and temperature systems, structural forms and the use of a wide range of heating equipment.
