AN IMPROVED ONLINE LEAKAGE DETECTION SYSTEM AND WATER FLOW MONITORING FOR MACHINE COOLING WATER CIRCUIT FOR CASTER ROLLS

摘要

The present invention relates to an improved system for online leakage detection and water flow monitoring in machine cooling water circuit for caster rolls reduce roll failure because of thermal fatigue due to under cooling . The system comprises at least one controller means for calculation for differential temperature , mass flow with density compensation and differential flow; at least two flow sensor means substantially installed in the inlet and outlet water line in the horizontal portion of the pipe line and operatively connected with controller means to measure the water flow through the each segment of caster; at least two temperature sensor means substantially installed in the inlet and outlet water line and operatively connected with controller means; at least two pressure sensor means substantially installed in the inlet and outlet water line and operatively connected with controller means; at least one human machine interface screen means .
