Continuous casting发表评论(0)编辑词条

Continuous casting (also called strand casting) is the process whereby molten steel is solidified into a "semifinished" billet, bloom, or slab for subsequent rolling in the finishing mills. Prior to the introduction of Continuous Casting in the 1950s, steel was poured into stationary molds to form "ingots". Since then, "continuous casting" has evolved to achieve improved yield, quality, productivity and cost efficiency. It allows lower-cost production of metal sections with better quality, due to the inherently lower costs of continuous, standardised production of a product, as well as providing increased control over the process through automation. Steel is the metal with the largest tonnage cast by this process, although aluminium and copper are also continuously cast.

Incidentally, Sir Henry Bessemer - of Bessemer converter fame - received a patent in 1857 for casting metal between two contra-rotating rollers. The basic outline of this system has recently been implemented today in the casting of steel strip.
