前言近年来,国外研究和开发了一种新奇的台车式连续加热炉,亦称为CCT炉。这种炉型摆脱了传统的推钢式加热炉和步进式加热炉的设计概念,而在炉内配备有诸多个台车,坯料就放在炉内台车陶瓷架上加热,台车在炉内移动,台车就相当于传统炉的炉底和实底段。 CCT炉型自1982年10月在西德一个中板车间问世以来,现在已经运行了四年多,目前在欧洲有五座台车式加热炉在生产,三座正在施工,其中美国一座,西班牙一座,联邦德国三座。主要用于加热初轧坯、板坯和管坯。它们的产量是45～400t/h。在CCT炉内无任何冷却部件,坯料加热均匀,出炉时坯料温差明显低于绝对温差30～49K。此值目前仅有现代组合式步进炉才能达到。同时坯料亦可出空。装有陶瓷台
Foreword In recent years, foreign research and development of a novel trolley-type continuous furnace, also known as CCT furnace. This type of furnace to get rid of the traditional push-type furnace and step furnace design concepts, and in the furnace equipped with a number of trolley, the blank is placed in the furnace trolley ceramic rack heating, trolley at Move the furnace, the trolley is equivalent to the traditional furnace bottom and real bottom. The CCT furnace has been in operation for more than four years since its debut in a mid-plate plant in West Germany in October 1982. Currently there are five trolley-type furnaces in production in Europe and three under construction, including one in the United States, one in Spain One, the Federal Republic of Germany three. Mainly used for heating initial billet, slab and tube. Their production is 45 ~ 400t / h. In the CCT furnace without any cooling components, the billet heating evenly, when the billet temperature was significantly lower than the absolute temperature difference 30 ~ 49K. This value is currently only achievable with modern modular step furnaces. Billets can also be empty at the same time. Equipped with ceramic table
