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.
Steel is more difficult to cast than iron. It has a higher melting point and greater shrinkage rate, which requires consideration during mold design. Risers should be given more capacity to draw from as the metal cools and shrinks.
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.
Precision Castparts Corp. is an American industrial goods and metal fabrication company that manufactures investment castings, forged components, and airfoil castings for use in the aerospace, industrial gas turbine, and defense industries.
Smooth cast surfaces (Ra 1–2.5 micrometres or 0.04–0.10 thou rms). Thinner walls can be cast as compared to sand and permanent mould casting (approximately 0.75 mm or 0.030 in). Inserts can be cast-in (such as threaded inserts, heating elements, and high strength bearing surfaces). Reduces or eliminates secondary machining operations.
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.
A converter is a company that specializes in modifying or combining raw materials [1] such as polyesters, adhesives, silicone, adhesive tapes, foams, plastics, felts, ...
A conversion coating is a chemical or electro-chemical treatment applied to manufactured parts that superficially converts the material into a thin adhering coating of an insoluble compound. These coatings are commonly applied to protect the part against corrosion , to improve the adherence of other coatings, for lubrication , or for aesthetic ...
