Test on continuous casting - 735 | | of aluminum and many tons of other alloys produced around the world each year. Continuous casting is a process by which molten steel is solidified into a billet, bloom, or “semi-finished” slab for subsequent rolling in finishing plants. Process Description: Continuous casting the process begins with the flow of molten steel from a ladle through a tundish to the moulder. The concept of continuous casting is the use of an open-ended mold to cast an indefinite length of the desired cross-sectional shape. Molten steel solidifies from the cooled outer surfaces inward during the casting process, ultimately producing a fully solid slab, bloom, or billet that can then be processed in a secondary rolling mill or shipped as product in semi-finished steel. Continuous Casting: The continuous casting process is now preferred around the world for many reasons and has become a powerful method to produce high quality products with less expense. Besides other ways, there are reasons why continuous casting is so important: Energy Savings: The energy savings of continuously manufactured using the elimination of soak pits, reheat furnaces and rolling mills primary to reduce energy consumption during the process. Less waste produced: The complete continuous casting process leads to this result due to the high efficiency of the entire process and the reduced exposure. of hot steel in the air is also a reason to reduce scrap production.
