Abstract
A magnesium hot rolling mill system including a rolling mill having at least two work rolls for rolling of magnesium sheet or plate, a hot coiler positioned on either side of the rolling mill for heating and maintaining a desired temperature of the magnesium sheet or plate, active thermal roller tables, a mill drive system for independently driving the work rolls for asymmetrical rolling of the magnesium sheet and a warm coil loading and payoff station.
Claims20
A magnesium rolling mill for reducing cast magnesium coils to a final gauge comprising:
- a reversing rolling mill having at least two work rolls for rolling of magnesium sheet;
- a hot coiler positioned on either side of the rolling mill having ducts with slotted air nozzles within the hot coiler for heating and maintaining a required temperature of the magnesium sheet being rolled by the roll mill to achieve the final gauge;
- and
- wherein the hot coiler is a convection type heater having an insulated housing and the ducts and air nozzles are positioned within the top, bottom and sides of the insulated housing for directing hot air against the top, bottom and sides of the magnesium sheet to prevent the magnesium sheet from being heated above air temperature.
