Solutions Across the Rolling Line
Slab Detection on Transfer Table
Uninterrupted sensor performance on hot / cold slab in high ambient temperature upto 290°C at charging transfer table without any water cooling.
Width Confirmation / Camber Detection
Precise laser distance sensor with 0.5mm accuracy working on both hot (upto 1300°C) and cold (black with scale) surface rated for high ambient temperature 60°C. Air/ water cooling options available.
Furnace Door Position Switch
1:1 replacement of old mechanical limit switch with a precise electronic position switch (ERC) with 3 switching points in chain driven mechanism. ERC has an easy programming, preset for operational ease and maintenance including internal encoder diagnostic monitoring
Exit slab detection inside RHF
Avoid failure of the slab hitting the furnace door or opening too early thus reducing the drop-out temperature.
High functional reserve sensors (2500mtrs) installed at the discharge side looking through steam, pollution, flames, water droplets for reliable slab detection
Retrofitting Position Sensor in Walking Beam Furnace
Production downtime due to discrete detection using series of proximity sensor to detect the position of the walking beam. Linear sensor provision not available in the cylinder. Installed position sensor externally mounted on the hydraulic cylinder to provide a continuous 4-20mA for better control compared NO contact from proximity.
Profile temperature measurement for improved strip quality
From point to profile temperature measurement allows operation team to improve strip quality by comparing edge temperature deviation and head and tail comparison.
