ELECTRIC MODEL DZHETYMOVA AM The deformation zone during rolling, Longitudinal OF ROLLING PROCESS AND CONTINUOUS ROLLING

摘要

1. Schematic model of the roll gap during rolling, longitudinal rolling process and a continuous rolling process, characterized in that the model of the deformation zone comprises two adjustable resistors or resistor connected in parallel, the electrical resistance value of one of them is set proportional to the thickness of the flat area or peal shaped cross-section of roll entering the mill rolls, and the size of another set of resistance proportional to the thickness of the flat area or pop river sectional shaped peal exiting the rolls, the dimensions of roll neutral sectional deformation zone is determined in proportion to the resulting impedance of these resistors, doubling its value, and when using double roll gap model in the form of a serial electrical connection made of two precision dual resistors host when moving the movable overall system equal resistance value, the amount of roll in a neutral section the deformation zone is determined proportional to their impedance to reduce interference is possible to use the model in the form of two adjustable precision quad resistors receiving while moving their common moving system the same electrical resistance value, and the process model longitudinal rolling comprises an electrical model of the roll gap, connected to the electric power source which is connected in series with two interconnected successively adjustable rheostats or replaced
