Pipes in Steel Ingots as Exemplified by Casting Wax

This paper presents some experimental data on the size and position of pipes steel ingots as exemp1ified by casting wax under various conditions and noting the size and location of the pipes formed. The results tend to show that the length of the pipe is decreased by: 1. Slow casting 2. By casting large end up instead of down 3. By retarding the cooling of the top

Opportunities in Materials Processing: Metal Casting

Revitalizing manufacturing in the US is a hot topic, and the $1B National Network for Manufacturing Innovation (NNMI) has three new centers focused on metal casting. For structural applications, magnesium casting, structural die-cast alloys, austempered ductile and compacted graphite cast iron, and high strength steel promise dramatic weight reduction and improved performance. Recent experiments and modeling at UAB focus on the development of such new materials and processing routes. A study of the rare earth content in an aerospace magnesium alloy is presented.

The Casting of Anodes for the Series System of Electrolytic Copper Refining

The electrolytic refining process, while usually considered an auxiliary process used in conjunction with pyrometallurgical extraction, deserves a special niche in the complex metallurgy of copper. The development of electrolytic copper refining, for example, is largely responsible for the prominence of the electrical industry. Conversely, it could be stated that the electrical industry played an important part in the development of the copper industry.
