THE EFFECT OF HEADER GEOMETRY ON TEMPERATURE DISTRIBUTION IN COLD ROLLING

摘要: The objectives in the cold rolling process include improved sheet surface quality, enhanced steel mechanical strength, and better solidification operations. Given increasing demand for higher more rapid production, thinner plates, attention has been directed toward parameter of temperature as a means achieving above objectives. Due to friction between work rolls caused during because changes piece plastic work, non-uniform distribution results along roll axial direction which ultimately leads improper undesirable expansion its axis. This, turn, causes an uneven slide on surface; hence, wavy surface. In this study, we used headers with variety nozzles cooling order achieve uniform thermal roll. method, system is applied such way that gains desired efficiency terms both optimized energy consumption
