The converting process occurs in a converter. Two kinds of converters are widely used: horizontal and vertical. Horizontal converters of the Peirce-Smith type (which are an improvement of the Manhès-David converter ) prevail in the metallurgy of non-ferrous metals. Such a converter is a horizontal barrel lined with refractory material inside.
Molten metal before casting Casting iron in a sand mold. In metalworking and jewelry making, casting is a process in which a liquid metal is delivered into a mold (usually by a crucible) that contains a negative impression (i.e., a three-dimensional negative image) of the intended shape.
The cast metal from the twin-belt continuous casting machine is synchronized with, and directly fed into, a hot rolling mill. Combining the casting and rolling operations can result in significant energy and cost savings over other casting processes which incorporate intermediate cast and reheat steps.
David Kirkaldy (1820–1897) was a Scottish engineer who pioneered the testing of materials as a service to engineers during the Victorian period. He established a test house in Southwark, London and built a large hydraulic tensile test machine, or tensometer for examining the mechanical properties of components, such as their tensile strength and tensile modulus or stiffness.
This resulted in the development of cast irons of greater strength suitable for critical engineering applications. [citation needed] “The Meehanite Metal Corp” was led by Oliver Smalley to license the processes to foundries. Many other patented casting processes were also established.
The U.S. Commerce Department said Wednesday it has finalized a $1.5 billion government subsidy for GlobalFoundries to expand semiconductor production in Malta, New York and Vermont. The binding ...
n November 1954, 29-year-old Sammy Davis Jr. was driving to Hollywood when a car crash left his eye mangled beyond repair. Doubting his potential as a one-eyed entertainer, the burgeoning performer sought a solution at the same venerable institution where other misfortunate starlets had gone to fill their vacant sockets: Mager & Gougelman, a family-owned business in New York City that has ...
