Definitions
- the invention relates to a method for flying work roll change in cast rolling and hot strip mills, in particular continuous hot strip mills.
- the work rolls of a rolling mill are subject to natural wear, which can lead to loss of quality at the surface of the rolled strip.
- the object of the invention is to allow in a continuous casting or a continuous hot strip mill a flying work roll change, thereby shortening / eliminating the buffer times in the oven, a reduction of the furnace, a reduction of investment costs, as well as lower energy consumption and thus a cheaper product - tion process to come.
- This object is achieved according to the invention with a method for flying work roll change in cast rolling mills and hot strip mills, in particular continuous hot strip mills, wherein for the exchange of beitswalzen by opening the roll stand these can be brought out of engagement with the hot rolled strip to be rolled, characterized in that on the rolled hot strip before and / or after entering the open mill stand via at least one insertable into the rolling line hold-down a controllable, the strip tension of the open Roll stand replacement strip tensioner can be applied.
- the hold-down function is taken over by a hold-down roller, which interacts with the ski lift. Since the space between the rolling stands are very limited, this hold-down role is run in a particularly narrow design.
- FIG. 1 shows the normal rolling process with the rolling stand closed
- FIG. 2 shows the rolling process at a roll stand open for roll change and active hold-down roll and in FIG.
- FIG. 3 shows a further hold-down roller active in the outlet region of the roll stand in order to reliably avoid contact of the strip with the upper work roll of the opened roll stand.
