09931692 · 2018-04-03 · ·

A hoisting type continuous casting device includes a keeping furnace, a first shape regulating member, an imaging section, an image analysis section, and a casting control section. The keeping furnace keeps a melt. The first shape regulating member is mounted in the vicinity of a molten surface of the melt kept in the keeping furnace and regulates a cross-sectional shape of a casting to be casted by the melt passing therethrough. The imaging section captures an image of the melt that has passed through the first shape regulating member. The image analysis section detects swinging motion in the melt from the image and determines a solidification interface based on presence or absence of the swinging motion. The casting control section changes a casting condition when the solidification interface determined by the image analysis section is not within a predetermined reference range.

Method and spraying apparatus for the thermal surface treatment of a metal product

The invention relates to a method and to a spraying apparatus (10) for the thermal surface treatment of a metal product (1). The metal product (1) is conveyed in a transport direction (T) through a treatment section (12) of a spraying apparatus (10) equipped with cooling nozzles (16) while cooling fluid is discharged through the cooling nozzles (16) of the spraying apparatus (10) onto the surfaces of the metal product (1), wherein the metal product (1) hasviewed in the transport direction (T) of the metal product (1)a front section (4) and a trailing rear section (5). The cooling of the surfaces of the metal product (1) within the spraying apparatus (10) occurs in such a manner that the rear section (5) of the metal product (1) is cooled more significantly than its front section (4). It is thereby achieved that an essentially uniform ferrite content forms in the material of the metal product (1) at a predetermined depth of the same over a longitudinal area extending between the front section (4) and the rear section (5).
