Experiences with Mathematical Modeling of Electro- Boost in Glass Furnaces

The goal of the latest strategy in glass companies is to decrease the cost of production while maintaining or increasing the glass quality. One of the perspective ways is to install the electric boosting into the existing furnace or to build the new furnace including the electric boosting. This strategy may be surprising as electric energy is generally more expensive than gas or oil （considering the cost per unit energy） but because of efficiency of use （ direct glass - melt heating by Joulean heat） it is inevitably cost effective. The use of the CFD modeling capability for electro - boost designing is presented in this contribution. The Glass Service Glass Furnace Model （ GS - GFM ） is used for investigating the optimal electrode arrangement and phasing, and moreover, for increasing the glass quality during the electro - boost applying.

Simulation of industrial man-machine systems

In the design of large industrial processes, ergonomics designers can benefit from the use of computer simulation of man/machine systems when on-site studies are too risky or costly and laboratory studies alone have questionable generalization. This paper provides an illustration of this methodology for a hot strip mill in the steel industry and a demonstration of ergonomic design applications. A special simulation package which was developed for small military systems was adapted to this large industrial case and applied to an older manually-controlled mill of the 1930s. The simulation model was then modified to reflect automation and manning changes found in the mills built in the 1950s and the simulation results verified the actual performance differences between these mills. Experiments in further design and manning changes were made in order to demonstrate the usefulness of simulation as a design-aiding technique.

Cooling rate effects on the microstructure and phase formation in Zr51Cu20.7Ni12Al16.3 bulk metallic glass

A detailed transmission electron microscope (TEM) study has been conducted to investigate the microstructures of the Zr₅₁Cu_20.7Ni₁₂Al_16.3 metallic glass formed at different cooling rates. It has been found that the most competitive crystalline phase to the amorphous structure is an oxygen-stabilized FCC NiZr₂-type phase, which in turn acts as the leading phase to trigger the formation of other crystalline phases in the slow-cooled alloy.     

Fabrication of Er3+/Pr3+ Co-doped soda-lime glass thin films using RF magnetron sputtering method and optical property characterization

Er^3+/Pr³⁺ co-doped soda-lime glass thin films have been fabricated using RF magnetron sputtering method and their structural and optical properties have been studied. Deposition rate, crystallinity, and composition of glass thin films were investigated by scanning electron microscopy, transmission electron microscopy, and electron probe micro area analysis. Refractive index, birefringence and binding characteristics have been investigated using a prism coupler and X-ray photoelectron spectroscopy. Er³⁺/Pr³⁺ co-doped soda lime glass thin films were prepared by changing substrate temperature (room temp. ∼550^∘C), RF power (90 W–130 W), and Ar/O₂ gas flow ratio at processing pressure of 4 mTorr. Glass thin films could be obtained at the optimized processing condition at 350^∘C, RF power of 130 W, and gas flow of Ar:O₂ = 40:0 with maximum deposition rate of 1.6 μm/h. Refractive index and birefringence increased from 1.5614 to 1.5838 and from 0.000154 to 0.000552, respectively, as the content of Pr³⁺ increased. Binding energy of Pr3d also increased as the content of Pr³⁺ increased.
