Energy-saving steel production apparatus and method thereof

摘要

The present invention relates to a energy-saving steel production apparatus, including an hot-rolling production line and a continuous casting equipment (5) for producing semi-manufactured products or billets (10), said production line and said equipment facing one each other and being connected through fast transport means (7) moving said billets (10). The invention also relates to a method for processing energy-saving steel, comprising the following steps:
a. taking the steel to a casting temperature;b. casting said steel in suitable moulds for obtaining a semi-manufactured product (10);c. transferring directly said casted semi-manufactured product (10) towards a rolling mill through fast transport means;d. taking said semi-manufactured product (10) to a value of temperature corresponding to a maximum value of plasticity;e. subjecting said semi-manufactured product (10) to a rolling process.

主权项

1. An energy saving method for processing steel, consisting of the following steps:
(a). taking the steel to a casting temperature higher than 1500° C.; (b). casting said steel in suitable molds to obtain a casted semi-manufactured solidified billet (10); (c). transferring said casted semi-manufactured solidified billet (10) that is at an average temperature of 850-900° C., that allows for complete solidification of said semi-manufactured solidified billet (10) to a rolling mill; (d). taking said semi-manufactured solidified billet (10) to a temperature corresponding to a maximum value of plasticity where said temperature corresponding to a maximum value of plasticity is between 1000° C. and 1150° C.; (e). subjecting said semi-manufactured solidified billet (10) to a rolling process characterized in that said step (d) occurs by means of intermediate rolls (2) provided with an induction-type tunnel furnaces.
