摘要:
The invention relates to a method of equalizing a solidification process of molten metal produced, in particular, during strand or strip casting, wherein the molten metal (10) is subjected, in particular, to an electromagnetic stirring process, and wherein a magnetic field is applied to metal located upstream of the area of, in particular, the electromagnetic stirring process. According to the invention, it is provided that during the solidification process, at least one magnetic field is applied to an already solidified, at the outside, into a strand, region (11) of the molten metal (10). The invention also relates to a device for carrying out this process.

A caster (1) has a casting ladle (2), a distribution device (4), and a horizontally moveable transport belt (5) having side limitation elements (13, 14) adjustable over the width of the horizontal transport belt. Liquid metal, preferably steel, can flow out of the casting ladle (2) into the distribution device (4), and from there can be fed to the horizontal transport belt (5)

The invention relates to a casting device (1) having a casting ladle (2), a distribution device (4), and a horizontally moveable transport belt (5) having side boundaries (13, 14), wherein liquid metal, preferably steel, can flow out of the casting ladle (2) onto the distribution device (4), and from there can be applied to the horizontal transport belt (5), the side boundaries (13, 14) of the horizontal transport belt (5) being adjustable across the width of the horizontal transport belt. The invention further relates to a corresponding method.
摘要:
In the casting close-to-the final dimension of rectangular strands made of metal and the subsequent further processing thereof into metal strips according to the DSC method (direct strip casting) in a horizontal continuous casting installation the cast product (4) is deformed during the solidification thereof into the preliminary strip (5) due to uneven heat dissipation because the top of the strip is cooled only by convection of ambient air and by heat radiation, while the bottom of said strip is in direct contact with a cooled metal conveyor belt (7). In this manner, the initially complete contact between the cast product (4) and the metal conveyor belt (7) is lost and the strip edges of the cast product arch upwards. In order to ensure in a simple manner maximum contact of the cast product (4) with the metal conveyor belt (7), thus optimizing and equalizing the heat transfer of ht cast product (4) to the metal conveyor belt (7) across the entire casting width, the invention proposes that pressure be applied from above to the cast produce (4) solidifying into the preliminary strip (5), preferably to the strip edges (6) thereof by means of a pressure device (11) disposed at the end of the metal conveyor belt (7) and, in order to compensate for the suddenly reduced cooling of the bottom of the preliminary strip upon leaving the metal conveyor belt (7), that the bottom of the preliminary strip be additionally cooled in a predetermined area directly behind the metal conveyor belt (7).
