圆块孔式石墨热交换器是武钢一米七系统用来加热酸洗介质——盐酸的。它是酸洗线上的关键设备之一,由国外引进。 为了解决该设备的备件供应问题,不影响酸洗线运行,从而确保一米七轧机正常生产,武钢冷轧厂(测绘设计)和东新电碳厂(制造)研制了KSH-1型圆块孔式石墨热交换器,在武钢冷轧厂酸洗线上投产试用,获得成功。 一、KSH-1型圆块孔式石墨热交换器 1.结构 该交换器的结构如图1所示,技术性能见表1。其外壳共七节,均采用16MnCu钢 Round hole graphite heat exchanger is Wuhan Iron and seven meters system used to heat pickling medium - hydrochloric acid. It is one of the key equipment on pickling line imported from abroad. In order to solve the spare parts supply problem of the equipment, it does not affect the operation of the pickling line, so as to ensure the normal production of the Mi-7 rolling mill. The KSH-1 round block was developed by WISCO cold-rolling mill (mapping design) Hole graphite heat exchanger, put into trial production on the pickling line of WISCO cold rolling mill and achieved success. A, KSH-1-type circular hole graphite heat exchanger 1. Structure The structure of the exchanger shown in Figure 1, the technical performance shown in Table 1. The shell of a total of seven sections, are used 16MnCu steel
