Apparatus for Continuous Casting

Abstract

Apparatus for continuous casting comprising a support structure provided with a containing casing configured to support inside it a mold equipped with a plurality of longitudinal passage channels for the passage of a cooling liquid. The containing casing and the mold together define an introduction chamber and a discharge chamber for the cooling liquid, and the introduction chamber and the discharge chamber are fluidically connected by the passage channels. The mold comprises a first tubular element and a second tubular element disposed inside the first tubular element. The second tubular element comprises a plurality of plates each provided with passage channels and connected to each other to define a through casting cavity. The first tubular element is provided with connection members to connect the passage channels of the plates respectively with the introduction chamber and with the discharge chamber.

Description

FIELD OF THE INVENTION[0001]The present invention concerns an apparatus for continuous casting that allows to continuously cast metal products such as slabs with a rectangular section and bars with a double “T” section, also known as “beam blanks”.[0002]In particular, the apparatus for continuous casting allows to install both crystallizers of the tubular type and also crystallizers of the plate type.BACKGROUND OF THE INVENTION[0003]An apparatus is known for continuous casting comprising a support structure or framework, defining a closed tubular support body, or body to support and contain the mold, hereinafter indicated as mold body.[0004]The mold body, depending on its particular constructional configuration, can allow to install a mold of the tubular type or plate type.[0005]Molds of the tubular type allow to obtain metal products with very simple and even cross section, for example blooms or billets with a round or square section, or with a more complex cross section but of lim...

AI Technical Summary

Benefits of technology

[0047]The first tubular element is provided with connection members to connect said passage channels of the plates respectively with the introduction chamber and with the discharge chamber and thus achieve the cooling of the plates.

[0048]The configuration described above therefore allows to associate crystallizers of the plate type to a substantially known support structure normally configured for the installation of tubular crystallizers, thus increasing the versatility of said structure.

[0049]According to another form of embodiment, a

Problems solved by technology

This cooling condition, precisely because of the impossibility of obtaining a differentiated cooling action on its walls, makes the molds of the tubular type not very suitable for casting products with shapes that are not even and uniform, particularly those of a large size, such as beams with a double “T” section, also called “Beam Blanks”.

In the case of products with large size sections, the walls of the tubular crystallizer are subjected to considerable deformations due both to the working pressure of the cooling liquid and also to thermo-mechanical stresses.

Direct connection means are not provided between the plates, since they could require an increase in thickness of the plates or could stiffen the structure t
