Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Oata Analysis and Synthesis (CINOAS) * at Purdue. University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 33 (thesis year 1988) a total of 13,273 theses titles from 23 Canadian and 1 85 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 33 reports theses submitted in 1988, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

Available in PDF, EPUB and Kindle. Book excerpt: "Mold flux plays a small but critical role in the continuous casting of steel. The carbon-coated powder is added at the top of the water-cooled copper mold, over time it melts and infiltrates the gap between the copper mold and the solidifying steel strand. Mold powders serve five primary functions: (1) chemical insulation, (2) thermal insulation, (3) lubrication between the steel strand and mold, (4) absorption of inclusions, and (5) promotion of even heat flux. All five functions are critical to slab casting, but surface defect prevention is primarily controlled through even heat flux. Glassy fluxes have high heat transfer and result in a thicker steel shell. Steels with large volumetric shrinkage on cooling must have a crystalline flux to reduce the radiative heat transfer and avoid the formation of cracks in the shell. Crystallinity plays a critical role in steel shell formation, therefore it is important to study the thermal conditions that promote each phase and its morphology. Laboratory tests were performed to generate continuous cooling transformation (CCT) and time-temperature-transformation (TTT) diagrams. Continuous cooling transformation tests were performed in an instrumented eight cell step chill mold. Results showed that cuspidine was the only phase formed in conventional fluxes and all observed structures were dendritic. An isothermal tin bath quench method was also developed to isothermally age glassy samples. Isothermal tests yielded different microstructures and different phases than those observed by continuous cooling. Comparison of aged tests with industrial flux films indicates similar faceted structures along the mold wall, suggesting that mold flux first solidifies as a glass along the mold wall, but the elevated temperature devitrifies the glassy structure forming crystals that cannot form by continuous cooling"--Abstract, page iv.

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The mold is one of the most important components of the continuous casting machine since the mold controls the shape and initial solidification of the steel product, where quality is either created or lost. During casting, the mold is submitted to heat flux from liquid steel on one side whereas the other side is water cooled, leading to the generation of large temperature gradients. It is also submitted to other stresses such as ferrostatic pressure and clamping forces. Casting can last several dozens of hours whereas the cooling step of the mold, when liquid steel is not poured anymore into the mold, can last only a few minutes. Maintaining a reliable, crack-free mold within close dimensional tolerances is crucial to safety and productivity. In order to withdraw the right amount of heat and to prevent mold distortion, mold is generally made of copper alloys that have the thermal and mechanical properties required for this function. The two copper alloys most widely used for casting mold are Cu-Ag and Cu-Cr-Zr. They present a wide range of thermal and mechanical properties due to the different treatments to which they can be submitted. The present master thesis aims to study the influence of thermomechanical properties of copper alloys on continuous casting mold behavior during casting and cooling, and more precisely on mold for continuous casting of steel slabs using realistic finite element models of heat transfer and stress. After realizing a literature review of the most widely used copper alloys, three finite elements models were developed in order to study the influence of three copper alloy grades on mold thermomechanical behavior. The three finite elements models were a 2D simplistic transverse section of the mold model, a 2D transverse section of the mold model that includes bolts and the backup plate and a 3D quarter mold model. Simulations of casting and cooling step were performed with ABAQUS 6.10® for the two most widely used copper alloys and a copper alloy that was previously submitted to a heat treatment. Simulations results show that the two copper alloys most widely used lead to similar mold behavior. Besides, the material submitted to a heat treatment does not lead to a critical behavior but can lead to a necessity of more frequent re-machining of the mold.

This book was released on 2007 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Melting behavior of mold powders during continuous casting plays an important role in the casting performance, production rate and steel quality. Carbon is an important constituent of the mold powders and in this study the effect of different carbonaceous materials on the melting characteristics of mold powders was evaluated. Different types of carbon were characterized quantitatively based on their internal structure. Reactivity experiments were conducted to establish a relationship between the structure of carbons, their reactivity and the melting rate of the mold powders. This study revealed that different types of carbon are comprised of different fractions of amorphous and crystalline structures, which in terms of reactivity have different activation energies. This in turn has an influence on the melting behaviour of the mold powder.
