热处理设备的发展,决定于热处理工艺的发展和生产需要。热处理设备又是耗能大的设备,它的发展必然受到能源供应的影响。热处理设备种类很多,可控气氛热处理设备是当前量大面广的一种。由于设备日趋实现机电仪一体化,其功能和性能都有较大提高。尤其是微电子技术在控温和碳势控制方面的应用,使炉气组分控制精确,可保证工艺的再现性,提高加热工件的质量,节省能源。近年,密封箱式炉向二室三室组合式发展,可用于几种热处理工艺。围绕节能,新的炉型、预抽真空炉问世。为减少热散失采用轻质保温材料,用焊接件和精密铸造件代替用传统工艺制造耐热物件以及余热利用等,不仅可节约能源且可避免环境污染。七十年代初,氮基气氛和滴注式可控气氛不断发展,取代了部分吸热型气氛的应用。低温有机液裂解装置问世,也为中小企 The development of heat treatment equipment, depends on the heat treatment process development and production needs. Heat treatment equipment is energy-intensive equipment, its development will inevitably be affected by the energy supply. Many types of heat treatment equipment, controllable atmosphere heat treatment equipment is the current large amount of a broad. Due to the increasingly mechanical and electrical equipment integration, its functions and performance have greatly improved. In particular, the application of microelectronic technology in temperature control and carbon potential control makes the furnace gas components accurately controlled, which can ensure the reproducibility of the process, improve the quality of the heated workpiece and save energy. In recent years, the sealed box furnace to the two-room three-room combination of development, can be used for several heat treatment process. Around energy-saving, new furnace, pre-vacuum furnace come out. In order to reduce the heat dissipation using lightweight insulation materials, welding parts and precision casting instead of the traditional process of manufacturing heat-resistant objects and waste heat utilization, not only to save energy and avoid environmental pollution. In the early 1970s, the nitrogen-based atmosphere and drip-controlled atmospheres were evolving to replace some of the endothermic atmospheres. Low temperature organic liquid cracker come out, but also for small and medium enterprises
