The developed adaptive feedforward controller was successfully implemented on the tandem hot strip rolling mill of voestalpine Stahl GmbH. The cooling pond will quench cool hot coils in six to eight hours, versus three days, before further processing on the 62" Continuous Pickle Line. With an annual capacity of more than two million tons, the rolling mill is more than a half-mile long and includes a walking beam reheat furnace, a two-high scalebreaker, five four-high roughers, a crop shear, six four-high finish mills, and two downcoilers. This data is collected in anticipation of finish rolling. The longitudinal tension in the strip is another important process variable to be controlled. Donate Grateful for your donation!
Once inside, the slabs are supported around 2. They roll and form coils of the transferred steel bar. High throughput for the HSM asks for a minimum number of passes in the roughing mill which is of particular importance for semi continuous HSM. For billet conveyance. This slab passes through the next phase of descaling where the iron layer is removed. Looper equipment Loopers are material accumulating devices used for transferring, winding, and unwinding rolled steel. The large number of teeth that simultaneously mesh reduces uneven rotation.

Home Your work environment Hot strip mill Hot strip mill Around a third of the products we send out to our customers, are hot rolled. Services Articles citing this article CrossRef 1. This controller stabilizes the movement of the strip in lateral direction, especially during the thread-in and thread-out process. Doubly fed induction generator use a back-to-back dual PWM converters that it can decouple of active power and reactive power, leading to reduce the system's frequency response. High Lub LT 2 EP is recommended for lubrication of plain and roller bearings exposed to medium to heavy loads.
Of course, as mentioned, with thicker hair it might just double the pain and be difficult to remove in one go for each strip. When you think about it, strip and hot wax are almost complementary. The warmth of the wax opens the pores while waiting to harden, this in theory, should make the treatment less painful Fewer ingrown hairs, less breakage and therefore longer re-growth periods. The approach systematically compensates for thermal inhomogeneity, inhomogeneous entry thickness, lateral asymmetries, and oil lubrication effects. The controller significantly improves the thickness accuracy of the final steel strip.
