Abstract: A method for rolling thin and/or thick slabs made of steel materials into hot-rolled strip, which were previously cast as thin or thick slabs in a continuous casting machine, heated to rolling temperature in a pusher furnace or in a walking-beam furnace, and rolled in a common rolling train, then cooled and wound into coils. The method is carried out in a continuous manner at maximum capacity of the roughing train according to the quality standard of the hot-rolled strip while roller wear is reduced due to the fact that the roughing train is formed inline by roughing stands and finishing stands into which thin slab sections or thick slab sections are introduced at a suitable point of the roughing train according to the thickness thereof.

Abstract: A series of inventions leading to the production of specific aluminum alloys (especially aluminum beverage can sheet product) through novel approach of introducing, selectively partitioning and managing alloying elements. This invention also enables manufacturing practices to enhance the performance characteristics of aluminum alloys produced. The selected elements can be derived from carbon anodes made from calcined petroleum coke with high metallic contents (such as nickel and vanadium). Alloying elements can also be introduced and managed from other raw material such as alumina and bath constituents added during aluminum smelting process. Additionally, cell operating parameters, such as cell temperature, off gas flow rate, aluminum tapping rate and impurity partition characteristics can also be manipulated to produce low cost aluminum alloys and facilitate utilization of high metallic content calcined petroleum coke.

Abstract: Thin steel strip is passed through a pinch roll stand comprising pinch rolls to a rolling mill comprising a pair of work rolls and upper and lower backing rolls. Strip passes through the bite between the work rolls and strip squeezing forces are applied between the work rolls to reduce the thickness of the strip. The pinch rolls apply tension to the strip passing to the work rolls. In order to minimize generation of crimping defects in the strip, the tension applied by the pinch rolls is high enough to ensure no part of the strip entering the work rolls is in longitudinal compression such as to exceed the buckling stress of the strip. The applied tension is sufficiently low as to produce no more than 1% strip elongation through creep. The strip may be hot rolled by the work rolls at a temperature in the range of 700° C.–1200° C.

Abstract: The invention relates to a method for producing steel slabs, whereby the strand leaves an ingot mold with melt enclosed by a strand shell and, in a strand guide located downstream, the opening width of guide rolls mounted in segments with upper and lower frames can be set in a continuous manner with successive steps by adjusting elements that join said guide rolls. An oscillation around a center line of the opening width serves to modify the opening width in order to render the dynamic influences on the guide rolls negligibly small. The amplitude of the opening width oscillation is set to a quantity, which does not provoke any plastic deformation of the strand shell. The actual opening width of the guide rolls is detected and the actuating force of the adjusting elements as well as the amplitude of the actuating force are determined at the same time.

Abstract: For each component which is used at a high in-service temperature for a long period, its creep damage degree is approximated by a relational expression containing the Larson-Miller parameter. The creep damage degree is estimated by an approximation expression obtained by determining constants for each component. The creep damage degree is subjected to Weibull statistical analysis to estimate the creep damage degree probabilistically. Also, the thermal fatigue and damage degree obtained by an approximation expression is likewise subjected to Weibull statistical analysis to estimate the thermal fatigue and damage degree probabilistically. Therefore, the probabilistically estimated creep damage degree and the probabilistically estimated thermal fatigue and damage degree allows the life of each component subjected to a high in-service temperature to be assessed precisely and quickly.
