Abstract
Continuous casting apparatus, comprising a mold and a crystallizer for the continuous casting of a metal product. The mold is provided with primary cooling means using a cooling fluid and associated with the walls of the crystallizer. A plurality of cooling members is installed downstream of the mold to perform a secondary cooling of the product, said cooling members comprising a plurality of delivery nozzles configured to deliver a liquid for cooling the product.
Claims12
A continuous casting apparatus, comprising a mold and a crystallizer for the continuous casting in endless, semi-endless or billet-to-billet of a metal product at a casting speed between 6 m/min and 15 m/min, the crystallizer having a casting cavity, into which the liquid metal is cast, defined by walls connected to each other in correspondence with edges and being provided with primary cooling means using a cooling fluid and associated with said walls,
- wherein the upper level of the liquid metal defines a meniscus,
- wherein said metal product is a billet, and
- wherein a plurality of cooling members are installed downstream of the mold to perform a secondary cooling of the cast product, wherein said cooling members comprise a plurality of delivery nozzles configured to deliver a liquid for cooling the cast product,
- wherein the delivery pressure at exit from said nozzles is comprised between 0.5 and 12 bar,
- wherein the specific water flow rates are 1.2-2.5 liters per kg of cast steel.
