带插件钢管换热器的研制与应用(上)

STUDY AND APPLICATION OF STEEL TUBE RECUPERATOR WITH IN-BUILT ELEMENTS (PART 1)

带插件的钢管换热器是近几年国外新发展起来的新型金属换热器,我国马钢高速线材厂组合式步进炉和宝钢热带步进梁式炉都引进了这种换热器。马鞍山钢铁设计研究院在消化吸收国外技术的基础上,已与无锡周潭冶金机械厂合作生产出了这种换热器,并在新余钢铁厂650轧机加热炉和马钢二轧厂500/450轧机燃油加热炉上试用成功。本文介绍了为掌握带插件钢管换热器的热工性能所开展的试验研究情况,以及这种换热器在工业生产中的使用情况。

Steel tube recuperator with in-built elements is recently developed up abroad as a new-type metallic heat exchanger, which has been imported by the combined walk furnace in High Speed Wire Works of MISC and the hot strip walk beam furnace of BGISW. On the basis of digesting and absorbing foreign technologies, MISDRI has developed and produced this kind of recuperators by cooperating with Wuxi Zhoutan Metallurgical Machinery Works, and the recuperators have been passed the production period successfully in the 650 reheating furnace of Xinyu Iron & Steel Works and in 500/450 oil-fired reheating furnace of Steel Rolling Works NO.2 of MISC. The experimental studies for obtaining the thermal properties of steel tube recuperator with in-built elements and its application in industrial production have been introduced in this paper.
