Converter main body is the core of the steel plant making workshop equipment , mainly from the furnace shell , trunnion ring trunnion bearing , tilting device and other components , usually assembled across and feeding cross between the stove . But because of the single piece of equipment is bulky , heavy quality , resulting in the installation, maintenance and renovation work has been extremely limited in space and lifting equipment , construction is also relatively difficult to minimize the external conditions , efficient ordered installed body equipment , saving engineering time and project cost savings , reduced maintenance costs , and significant . In this paper, 210 tons of new steel group the large converter body equipment installation engineering -line assembly and integral mounting construction process , from the basis of detection equipment installation , trunnion bearing assembly, sliding beam design a detailed calculations and discussed in prior to the installation process has not paired to form a system process cut key installation and new technology in the project , carried out technological innovation, assembly process design of key technologies for large-scale converter line research and implementation process , mainly include three aspects : the converter line assembly the slip device technology research ; the three spherical support device installed key technologies ; trunnion installation key technology in pairs to cut the key .
