Abstract
A transport system for flat metallic materials such as thin, hot-rolled metallic strips in a strip mill includes a roll table and one or more linear drive elements which are positioned between a pair of rollers of the roll table and below the table plane formed thereby to exert a travelling force field on the leading end of the flat metallic material passing thereover which will have a force component directed perpendicularly to the direction of movement of the flat metallic material and thus act to adjust (i.e. center) the positioning of the moving metallic material on the roll table. The linear drive elements may include heat shields and cooling fluid discharge openings.
Claims16
A system for transporting a thin hot-rolled metallic strip through a strip mill towards a feed guide, said system including
- a roll table which includes a multiplicity of aligned rollers over which the thin hot-rolled metallic strip passes, the upper peripheries of said rollers forming a table plane and said roll table having a center line therethrough,
- at least one linear drive element positioned between at least one pair of rollers of said roll table, each linear drive element being located below the plane of said roll table, and
- a power supply means for said linear drive elements, said power supply means supplying current to said linear drive element(s) when a thin hot-rolled metallic strip passes over the roll table which is not centered over the center line of the roll table to cause the leading end of the thin metallic strip to move laterally towards the center line of the roll table.
A system for transporting a flat metallic material through a metallurgical plant which includes a roll table having a multiplicity of aligned rollers, the upper peripheries of which form a table plane, and a linear drive element positioned between one pair of rollers and below said table plane, said linear drive element including means for discharging a fluid medium upwardly towards the flat material on the incoming side thereof to act as a coolant cushion.
