A coiler drum cleaner for cleaning the drum of a coiler furnace (typically associated with a reversing rolling mill or Steckel mill) is disclosed. The coiler drum cleaner includes a cleaning element rotatably mounted at one end of a longitudinally extending tubular member, the tubular member being movably installed in association with a coiler furnace such that the cleaning element may be inserted into the coiler furnace and moved across the surface of the coiler drum, by moving the tubular member substantially parallel to the axis of rotation of the coiler furnace drum. The tubular member also includes means for moving the cleaning element roughly perpendicular to the longitudinal axis of the tubular member so as to bring the cleaning element into contact with the drum. In use, the cleaning element is inserted into the coiler furnace, brought into contact with the coiler drum and rotated so as to clean the coiler drum. Preferably, the cleaning element is a cylindrical brush having a plurality of resiliently-flexible carbide-tipped steel tines arrayed about its circumference. The tubular member may also include cooling means.

Apparatus for cleaning a coiler furnace drum

A self-contained unitary assembly for peripheral devices normally located close to a Steckel mill is provided. The assembly has a frame open at both ends to receive and pass through the steel product being rolled. Above and below the pathway for the steel product are located transversely spaced arrays of descaler nozzles and their headers and also controlled cooling nozzles and their headers. Also included within the unitary assembly is the x-ray measuring gauge or other suitable measuring instrument for measuring some characteristic of the steel product. The unitary assembly is positioned between the pinch rolls and the Steckel mill. Protective steel plates or beams are provided running both transversely and longitudinally within the frame for the assembly to provide protection for the nozzles and measuring apparatus. These protective elements also serve to minimize the amount of errant water spray that might otherwise tend to enter the coiler furnace.

Unitary assembly of peripheral devices for use with steckel mill

Modular roll apparatus particularly suitable for conveying hot material such as a sheet of steel being processed. Each roll has its own individual water bath and drive mechanism. A water trough isolates the bath from the bearings and drive mechanism for the roll and bathes the underside of the roll to cool it. The entire modular unit can be removed from its operating position and replaced by a similar such unit. A conveyor containing a multiplicity of such units is suitable for conveying hot sheet steel or other hot material in a processing mill.
