能源是世界经济发展的关键之一,为此日本热处理业对能源的节约极为重视,近年来作了大量节能工作。他们除了一般的采用炉子设备连续使用,取消无实际意义的工艺过程进行节能外,还采用了一些节能设备和工艺技术。 1.设备节能:绝热保温材料的应用,有陶瓷纤维制品及真空成型发热体超轻绝热材料;余热利用;严格的测量控制,特别在温度测量上,采用了填充镁砂的实芯热电偶。 2.技术方面:缩短加热时间;直接淬火;省略回火工序;减少热处理层深;采用热处
Energy is one of the keys to the development of the world economy. To this end, Japan’s heat treatment industry attaches great importance to energy conservation and has made a large amount of energy conservation work in recent years. In addition to the general use of furnace equipment for continuous use, the cancellation of non-meaningful process for energy saving, but also using a number of energy-saving equipment and technology. 1. Energy-saving equipment: the application of thermal insulation materials, ceramic fiber products and vacuum forming heat insulator ultra-light insulation materials; waste heat utilization; strict measurement control, especially in the temperature measurement, the use of filled solid magnesia thermocouple. 2. Technical aspects: shorten the heating time; direct quenching; omit the tempering process; reduce the depth of heat treatment; the use of heat
