Reduction of surface defects during finish rolling of hot strip
The invention relates to a finishing train for finish rolling hot strip. It is the object of the invention to modify an existing finishing train in such a way that the surface quality of the hot strip produced is improved without, however, significantly increasing the use of energy during production. This is intended to enable the thin hot strip produced to be used even for applications with high demands on surface quality. This object is achieved by a cleaning nozzle which cleans the upper side of the exit table, thus ensuring that scale and/or rolling dust are/is removed from the exit table.
Casting-rolling integrated plant for producing a hot-rolled finished strip from a steel melt
A casting-rolling integrated plant that is capable of producing, from a steel melt, in a cost-effective manner and with high productivity, a hot-rolled finished strip having a thickness of 0.6 mm, an excellent flatness, and an excellent profile by dividing the thickness reduction into at least three stages (roughing, intermediate and finishing train), measuring the actual profile after the roughing, intermediate and finishing train, and equipping the stands in the roughing, intermediate and finishing train with actuators for influencing the strip profile and/or the strip flatness.
