LINES<\/p>\n<\/h1>\n
Continuous casting is the process that leads directly from liquid metal to the semi-finished product. \nIn this way, it is possible to produce bars, profiles, strips and tubes both in steel and in non-ferrous metals such as copper and aluminium.<\/p>\n<\/h2>\n
<\/p>\n
In particular, with regard to the latter metal, the number of alloys that can be used with this process is increasing. \nThe absence of heating and remelting processes in the production cycle, in some cases up to \nrecasting, makes the various continuous casting processes quite interesting.<\/p>\n<\/div>\n

The reduction of costs is intuitively a peculiar advantage and will be a source of savings, as the higher is the melting point of the material, the higher is the casting temperature. \nIt is therefore not surprising that roughly 90% of steel (melting temperature = approximately 1400 \u00b0C) processed worldwide has adopted this procedure in the production cycle. \nIn the aluminium sector (melting temperature = approximately 700 \u00b0C) the processes that include continuous casting are used in lower, yet still important, percentages.\nThe products obtained from continuous casting can be divided into two distinct types. \nThe first one leads to the production of plates with a reduced thickness and a wide width, used as stock for thin sheets, cooling fins, capsules and cans. \nThe second one is characterized by the continuous production of bars, which can be used without further processing or after subsequent<\/p>\n<\/div>\n
rolling, to produce wire rods of various diameters. This casting pattern can also be applied to the casting of large bars, so as to allow the production of ingots of various weights by cutting the length of the bar.<\/p>\n<\/div>\n

This method is also advantageous for obtaining a good level of quality when producing semi-finished products<\/p>\n<\/div>\n<\/li>\n
In particular, continuous casting allows optimal control of the cooling and, consequently, the microstructure of the products is uniform<\/p>\n<\/div>\n<\/li>\n
Compared to in-mould melting, continuous casting also reduces the amount of waste generated. \nMoreover, the properties of the products can be easily modified by changing the melting parameters.<\/p>\n<\/div>\n<\/li>\n
Since all operations can be automated and controlled, continuous casting offers numerous possibilities to adapt production both flexibly and quickly to changing market needs and combine it with digitization technologies.<\/p>\n<\/div>\n<\/li>\n<\/ul>\n
Briefly, the production of bars from continuous casting and the subsequent rolling for the production of wire rods is carried out according to the following format: in the continuous casting of bars, the liquid metal passes into the groove of a cooled wheel and solidifies while \ntaking on the shape of the groove. \nSubsequently, the semi-finished product coming out of the wheel is continuously deformed, passing through a series of rolling stands which gradually shape the rough unit until it is transformed into a round wire of the desired diameter.<\/p>\n<\/div>\n
