Continuous Casting

چکیده
Continuous casting is used to mass produce basic metals into long, semi-finished shapes with constant cross section, which are later processed into over 800 million tons of steel, 20 million tons of aluminum, and 1 million tons of copper, nickel, and other metal products in the world each year. Cross-sections can be rectangular, for later rolling into plate or sheet, square for long products, circular for wire and seamless pipes, “dog-bone” shapes for “I” or “H” beams, and even thin strip, rod, and other products. Continuous casting is distinguished from other solidification processes by its “steady state” appearance. That is, the molten metal freezes against the mold walls and is withdrawn from the bottom of the mold at a rate which keeps the solid / liquid interface at a constant position with time, relative to an outside observer. The process works best when all of its aspects operate in this manner.

متن کاملPhysical Modeling of Steel Delivery during Thin Slab Continuous Casting
A full scale physical model of a thin slab caster with a four-hole design submerged entry nozzle (SEN) was constructed. On the basis of the dimensionless Reynolds and Froude similitude criteria, the fluid flow in a full-scale model is similar to that of the actual system and, hence, the data obtained from the water model can be applied to the actual system. In order to determine the optimum ope...
