Influence of High-Sulfur Cokes on Anode Performance in Alumina Reduction

Abstract: The characteristics of a variety of fluid and delayed cokes have been examined both in the laboratory and as fillers in statistically significant numbers of full-size reduction cell anodes. Sulfur content ranged 1–5%; sulfur emission and anode performance indicated unique coke properties independent of sulfur level. Performance of high-sulfur filler anodes ranged from excellent to poor, and depends much more on the amount of oxidant-accessible surface than on sulfur level. The significance of coke blend compatibility was investigated to improve anode performance with available fillers as coke quality changes.

Evaluation of a proposed standard method of testing for susceptibility to stress-corrosion cracking of high-strength 7XXX series Aluminum alloy products

Abstract: A task group sponsored jointly by The Aluminum Association and the ASTM has recommended a standard method of test for susceptibility to stress-corrosion cracking (SCC) of 7XXX aluminum alloy products (ASTM G 47-76). The proposed standard is a comprehensive method that specifies the corrosive environment and period of exposure, type of test specimen and method of loading, procedures for sampling various manufactured product forms, and guidelines for interpretation of test results. Final selection of test procedures was based on round robin tests performed in nine different laboratories and 3-year exposures to the atmosphere in both seacoast and inland industrial locations. A summary of test results is given to illustrate how the relative performance of three different tempers of 7075 alloy plate can be influenced by the choice of a test specimen, differences in the outdoor atmosphere, and interlaboratory variations in performing the standard 3.5 percent sodium chloride alternate immersion test.

Heat exchange structure

Abstract: A heat exchange structure is constructed from refractory blocks having three linearly aligned flue-forming openings extending from top to bottom of the block. The central opening is surrounded on four sides by refractory and the two end openings are surrounded on three sides. These refractory shapes are assembled in an open basketweave structure to form the heat exchanger. The resulting structure contains vertically extending, interconnected flues of two types, (1) flues of a first type interconnected at alternate layers in the structure to each of the four contiguously adjacent flues and (2) flues of a second type connected to opposed pairs of contiguously adjacent flues at alternate levels and to the other pair of contiguously adjacent flues at the intermediate levels. The net result is a stable heat exchange structure with relatively thin walls, relatively large flues, and means for creating turbulence in gas passing through the exchanger, thus increasing the rate of heat exchange.
