Rolling mill force measuring apparatus

Abstract: A means for making a simple and economical roll force measurement on rolling mill stands. A strain gage consisting of a half-bridge of vertical and horizontal semiconductor strain elements is cemented to opposing strain sites on a given post of both side frames of a rolling mill stand. These half-bridges are wired into a full-bridge strain gage circuit for each post which is responsive to post strain as a function of roll force, but is not responsive to bending moments in the post. Thermal variations affecting strain gage sensitivity are compensated for by energizing each full-bridge circuit with a separate constant current source. Thermal and mechanical drift affecting strain gage zero are compensated for by automatically nulling amplified strain gage output signals by electronic means during the absence of a workpiece in the rolling mill stand. Roll force signals from individual posts, or their sum, are selectively fed to a utilization device such as a roll force indicator or controller.

High energy pump system for use in the descaling of steel

Abstract: This invention relates to a descaling system for use in the manufacture of steel and corresponding method, including a pump recirculation system. The recirculation system is adapted to make high pressure descaling fluid (e.g. water) instantaneously available to the descaling nozzles for spraying, and to maintain a temperature differential between the pump suction and pump discharge less than about 25° F. during both descaling and recirculation.

Deformed wire for concrete reinforcement

Abstract: A wire having overlapping rows of indentations in the surface thereof whereby deformation roll wear and/or improper roll adjustment are visually indicated by the deviations from the desired amount of overlap.

Empty hopper detector

Abstract: A pivotable probe arm in a batch hopper automatically indicates when the hopper is empty, and in an alternate embodiment, also automatically closes the discharge opening when the hopper is empty.
