Abstract
A strip mill using movable coiling furnaces that are in a first position horizontally aligned with the pass line eliminates the need to deflect the strip into the furnaces. In a second position the movable furnaces are displaced from the pass line to allow strip to pass without obstruction. The roller table is also movable to permit the furnaces to align with the pass line but may be aligned with the pass line when the furnaces are displaced.
Claims21
A strip mill for working a strip of material comprised of:
- a) a roller mill;
- b) a roller table defining a pass line positioned on opposite sides of the roller mill to pass the strip of material to and from the roller mill;
- and
- c) a coiling furnace positioned on at least one side of the roller mill adjacent the roller table with the furnace having an access opening for both receiving and discharging the strip to a coiling drum mounted within a furnace housing, wherein the furnace is movable between
- i) a first position in which the furnace opening extends into the pass line;
- and
- ii) a second position in which the furnace access opening is away from the pass line and the pass line is unobstructed by the furnace.
In a hot strip mill having a roller mill for working a strip of material, a roller table defining a pass line and positioned on opposite sides of the roller mill to pass the strip of material to and from the roller mill, and a pair of coiling furnaces each having an access opening for both receiving and discharging the strip to a coiling drum mounted within a furnace housing, a method for directing the strip of material to enter and exit one of the coiling furnaces or to proceed along the pass line unobstructed by the coiling furnaces comprising the steps of:
- a) positioning the coiling furnace to a first position where the access opening extends into the pass line;
- and
- b) positioning the coiling furnace to a second position where the furnace access opening is away from the pass line such that the pass line is unobstructed by the furnace.
