Established the precise model and completed the virtual assembly of CVT with diclinic cam plate synchronous revolution and internal power shunt application of Pro/E software basing on the transmission principle. Obtained the displacement, velocity and acceleration time-dependent curves of nine plungers' centroid through the simulation of transmission operation, based on the simulation analysis gaining that the transmission does not exist in dynamic and static interference, and the structure design of CVT is reasonable. Completed the processing of CVT manufacturing, experiments are carried out to verify the simulation analysis of the transmission of real. © (2013) Trans Tech Publications, Switzerland. Source

In this article, a previous mechanical model is extended to predict raceway penetration in a blast furnace (BF) and to dynamically illustrate how raceway penetration varies over time after the blast velocity varies based on Newton's second law. The model is validated by industrial measurements, and more precise predictions have been obtained using the present model. Moreover, the effects of combustion reactions on the raceway shape and size are taken into account in the present model. The mechanism for raceway formation and variation revealed by the present model is as follows: Fast movements of packed bed above a raceway roof due to blast blowing rate variation make raceway size vary rapidly and form its prototype; combustion reactions modify raceway size and shape, and they maintain its stability. © 2013 The Minerals, Metals & Materials Society and ASM International.

The nonisothermal crystallization behavior of mold fluxes bearing various TiO2 was studied by using the single hot thermocouple technique. The mineral components of the mold fluxes were analyzed by X-ray diffraction (XRD) and microscopically observed by mine-phase microscope. The results indicate that cuspidine is the main phase of the casting mold fluxes. With a certain amount of TiO2 (2% to 8%) added into the mold fluxes at high basicity (ΣR=1.3), the phase precipitation increases. Small amount of Ca2SiO4, Ca2Al(AlSi7 O7), Ca2SiO2F2 and CaTiO3 are crystallized. While the time of crystallization process of the mold fluxes is lengthened, the crystallization ratio and crystallization rate of the mold fluxes is decreased. Thus, crystallization of the mold fluxes is inhibited, leading to improvement in the glass property and the lubrication between casting strands and molds in view of the heat flow control of slag films.
