A method and apparatus of making coiled plate, sheet in coiled form or discrete plate. The apparatus includes a continuous strip caster forming a strand of intermediate thickness; a shear for cutting the strand into a slab of desired length; a slab table including a slab takeoff operable transverse of the conveyor table; a slab collection and storage area adjacent to the slab conveyor table adapted to receive slabs from the slab takeoff; one or two reheat furnaces having an entry inline with both the slab conveyor table and the slab collection and storage area for receiving slabs from either; a feed and run back table at the exit of one reheat furnace; a single or twin stand hot reversing mill for reducing the slab to a coiling thickness in a number of flat passes; and a pair of coiler furnaces located on opposite sides of the hot reversing mill.

A hot strip mill having a final reducing stand and runout cooling means downstream of the reducing stand includes an incubator capable of coiling and decoiling the hot strip. The incubator is located intermediate the runout cooling means. In a preferred form the final reducing stand is a hot reversing mill. A second incubator and/or a temper mill and/or a slitter may be positioned downstream of the first incubator. The method of rolling includes isothermally treating the strip within a predetermined time and temperature range in the incubator prior to subsequent processing. The subsequent processing may include any one or more of the following: further deformation by cold rolling, temper rolling or cooling at a desired heat loss rate.

The present invention provides a hot reversing rolling mill for isothermally reducing a metal strip product. The mill includes a hot reversing mill stand with a pair of coilers positioned on opposite sides of the mill stand. At least one heater is positioned between one of the coilers and the mill stand with at least one strip cooling unit positioned between one of the coilers and the mill stand. A sensor is provided for sensing a strip parameter indicative of strip temperature as well as a controller for controlling each of the heating and cooling units in response to the sensed parameter. The rolling mill of the present invention can be utilized for isothermally rolling multiple passes of a metal strip product on the hot reversing mill.

A valve body includes a chamber for the flow of fluid between an inlet and an outlet thereto. The chamber includes an upper portion with an opening therethrough and a lower portion including a valve seat between the inlet and outlet. A bonnet is positioned in the chamber upper portion and is connected to the valve body and extends upwardly therefrom. The bonnet includes a passageway, and a stem is positioned in the passageway for longitudinal movement into and out of sealing engagement with the valve seat. An actuator is rotatably positioned in the bonnet passageway above the stem. A micrometer operating handle is nonrotatably connected to the upper end portion of the actuator to facilitate fine adjustment of the stem position to provide incremental adjustments in the flow rate of fluid between the inlet and outlet. The stem upper end is spaced from the actuator lower end in the bonnet passageway, and a coupling assembly rigidly connects the actuator to the stem for conversion of longitudinal rotational movement of the actuator to nonrotational longitudinal movement of the stem. The coupling assembly includes a housing into which both the actuator and stem extend.
