PREPARATIONS OF FERRIMAGNETOFLUIDS AND THEIR APPLICATIONS IN MINERAL PROCESSING袁楚雄,刘奇摘 要:<正>In this paper the research results on the preparation... which produces ultrafine Fe3O4 particles. Theparticles may then be collected by sodium oleate into kerosene phase andthus forming stable oil-base ferrimagnetofluid, or, alternately, the parti-cles may......
Forming process of cross-connected finned micro-grooves in copper strips CHI Yong(池 勇), TANG Yong(汤 勇), CHEN Jin-chang(陈锦昌), DENG Xue-xiong(邓学雄), LIU Lin(刘 林), WAN Zhen-ping(万珍平), LIU Xiao-qing... ‘pore-groove’ structure. On the fringe of grooves, there are micro fins that are advantageous for the core forming. So the cross-connected finned micro groove structure can be defined as ‘pore-groove-fin......
to the experiment, the forming process of 3D integral fin by rolling-ploughing-extrusion compound processing methods includes two steps. The first is rolling process, and the following is P-E processing... groove in forming processing of current groove. The bulge between the fringes of two grooves changes into a low and shallow U-shaped groove, so a kind of compounded structure comprising of V-shaped......
