titleOfInvention A kind of hot rolling forming method of centrifugal casting bi-metal double abnormity ring
abstract A kind of hot rolling forming method of centrifugal casting bi-metal double abnormity ring, belongs to ring processing technique field, it is characterised in that comprise the following steps that:(1)According to the size of duplex-metal special ring, rolling ratio is calculated K With the size of ring billet;(2)Rolling hole type design:Using enclosed pass rolling, driven roller is the cylindrical roller that middle part carries outer step, and core roller is that middle part carries upper and lower outer step, is taper cylinder between upper and lower outer step, the tangent conjunction of between outer land terrace of driven roller and core roller forms forming cavity;(3)Rolling forming is processed:The internal layer Q345B of centrifugal casting, outer layer 40Cr bimetallic ring billets are heated, determine ring billet internal layer, outer layer initial temperature and driven roller rotating speed and core roller variable-speed feeding speed speed, when internal layer temperature is down to 820 ~ 850 DEG C, rolling terminates.The method have the advantages that equipment investment is small, and energy-saving material-saving, the inside and outside layer interface bond strength height of duplex-metal special ring.
