(2009) 16: 0738-0742 DOI: 10.1007/s11771-009-0122-3 Deformation division of metal flow behavior during extrusion process of 7075 aluminum alloy LI Feng(李 峰)1, CHU...; Abstract: To reduce defects caused by non-homogeneous metal flow in conventional extrusion, a die with guiding angle was designed to improve the metal flow behavior......
and material quantity. Based on operating principles of material flow, control methods were optimized, such as product organization mode, scheduling discipline and scheduling plan of hot metal ladle... interface system will realize high-efficiency control by using this control technology.Key words:ironmaking and steelmaking interface; torpedo ladle; hot metal ladle; material flow control; control......
gas scatter angle. The results show that the structure of primary atomizer plays an important role in the flow field near the exit of delivery tube. Metal protector with conical surface at the body... zone, which causes a drag force on the melt in the delivery tube to keep steady metal flow. A close combination between closed atomizer and the delivery tube makes the kinetic energy transformed easily......
