Atmospheric corrosion resistance of skyward- and groundward-exposed surfaces of zinc- and 55% Al-Zn alloy-coated steel sheet

Abstract: Zinc-coated (galvanized) and 55% Al-Zn alloy-coated steel sheet was tested for atmospheric corrosion resistance for 20 years in rural (Saylorsburg, Pennsylvania), industrial (Bethlehem, Pennsylvania), moderate marine (250-m [880-ft] lot, Kure Beach, North Carolina), and severe marine (25-m [80-ft] lot, Kure Beach, North Carolina) environments. Corrosion losses were determined separately for skyward- and groundward-exposed surfaces and compared to results for conventional two-sided coupons, which gave only an average of skyward and groundward surfaces. Results were fitted to exponential equations of the form C = ATB, where C is the corrosion loss, T is time, and A and B are constants. Coating lives were estimated based upon extrapolation of these equations to the time to reach a corrosion loss equal to the coating thickness. On average, the estimated life of a skyward-exposed 55% Al-Zn alloy coating was 12 times that of a galvanized coating of equal thickness (25 μm).

Method and apparatus to determine and control the carbon content of steel in a BOF vessel

Abstract: Apparatus for determining in-blow % carbon content and/or the First Turn Down Carbon of a BOF heat includes a light sensor housed within a temperature regulated case having a sighting window including air wipe means to shield the light sensor from steelmaking dust and fume. The apparatus also includes a means to generate a signal that corresponds to the amount of oxygen blown into the BOF during a heat, and a programmable logic controller. The logic controller is programmed to continuously process oxygen blown signals from the signal generating means, and light intensity signals received from the light sensor. The program calculates continuous in-blow % carbon content of the heat based upon the difference in light intensity from a point of maximum light intensity emitted from the BOF vessel in relation to the amount of oxygen blown into the BOF vessel during the same period of time.

Base bracket for shelving

Abstract: A base bracket comprises a heel and hook member, a heel reinforcement, a bottom swing tab, and a backload pin. When the bracket is properly positioned in a slot in a shelf upright, the pin is adapted to pass through aligned holes in the shelf upright, the hook, and the bottom swing tab.
