Casting technology

Because beryUium is primarily used as a powder metaUurgy product or as an aUoying agent, casting technology in the conventional metaUurgical sense is not commonly utilized with the pure metal.

Fused basalt is utilized chiefly in the manufacture of floor tiles, castings for cyclone and other separators, nozzles, augers and grate bars the centrifugal casting technology is used in the production of conveyor pipings for mines, mill corps, etc. A special case is represented by the application of fused basalt for the incorporation of radioactive wastes. Fused rocks are dealt with in the extensive series of studies by Voldan (1955 — -1976).

During the period of 1965 to 1972, the best data on flux and salt rejection for cellulose acetate membranes were exhibited by the composite membranes. However, these membranes never reached commercial viability efforts on them died out completely by 1975. Reasons for this appear to be threefold. First, composite cellulose acetate membranes were technically difficult to scale up. Second, the advent of noncellulosic composite membranes in 1972 (the NS-100 membrane) offered much more promise for high performance (salt rejection and water flux), especially for seawater desalination. Third, continual improvements in asymmetric cellulose acetate membrane casting technology (such as the development of swelling agents and of blend membranes) brought the performance of asymmetric membranes to full equality with composite cellulose acetate membranes. 

Further improvements in superalloys have depended on alternative manufacturing routes, particularly using modern casting technology like vacuum casting [9].

Examples of lO Mindset applications that can contribute to faster, better and safer work practices are for example team casting, technology development and tailoring training programmes.
