Metal strip tensioning apparatus for use in a continuous cold reduction method and mill for metal strip in which the trailing end of a metal strip passing through the mill is welded to the leading end of a metal strip coming off a new coil without stopping the mill, the trailing end portion of the metal strip passing through the mill being paid out from a metal strip storage system during the welding operation with a resulting loss of close control of the lateral metal strip position at the entry side of the first mill stand, the present invention providing a method and means associated with a metal strip back tensioning unit ahead of the first mill stand for correcting the lateral position of the metal strip issuing from the metal strip storage system while applying the tension of the metal strip in the metal strip storage system to the metal strip entry side of the back tensioning unit. The metal strip back tensioning unit serves the dual function of placing metal elongation tension on the metal strip going to the first mill stand while closely controlling the centering of the metal strip in the first mill stand.

Substantially horizontal rotary drum system for quenching and cooling coke, the drum having an internal helical conveying vane for moving the coke through the drum upon rotation of the drum, the diameter and the length of the drum and the pitch of the helical vane being such as to convey predetermined amounts of coke through the drum in the time periods required to quench and cool the coke with the drum rotating at speeds which will not cause undue attrition of the coke. Water sprays are arranged at the coke entry end of the drum, screens to drain excess water from the drum are present near the coke delivery end of the drum and a steam exhaust hood closes the coke delivery end of the drum. A conveyor conveys coke away from the coke delivery end of the drum, the hood including enclosure means for the conveyor. The helical vane is tapered through part of a convolution at the coke entry end of the drum to accept the coke without crushing and at the exit end of the drum to smooth out the rate of delivery of the coke to the conveyor.

An improved ladle transfer car for transporting ladles and providing accurate and consistent weight measurements for the ladle and its contents. In a preferred embodiment the ladle transfer car comprises a car body supported upon multiple truck assemblies. Connecting each of the truck assemblies to the car body is a shear beam load cell pin. Associated with each of the truck assemblies is a stabilizer assembly. The stabilizer assemblies permit the vertical movement of the car body relative to the truck assemblies and they help to prevent the horizontal movement of the car body relative to the truck assemblies. Each of the stabilizer assemblies includes a pivot arm which extends substantially perpendicular to the major axis of the truck assemblies. The pivot arm is pivotally connected at one end of the car body and pivotally connected at the other end to a respective truck assembly. Mounted in the immediate proximity of each of the shear beam load cell pins is a keeper assembly.
