Abstract
A methodology to monitor, maintain and improve the descaling practices at the Tata Steel Direct Sheet Plant has been designed and developed at both plant and laboratory levels. The results of laboratory scale and in-line testing have allowed a descaling process window and maintenance plan to be developed founded on the final product requirements. An in- house-designed descaling pilot rig was used to test nozzles in single and dual configurations. The system is able to perform in static and dynamic modes on both hot and cold materials. The test rig is adaptable to most commercially available flat fan nozzle types. The material chosen for the impact tests presented here was aluminum. In order to assess the influence of rake angle, pilot mill static descaling tests were undertaken, as prescribed in the experimental procedures section, for rake angles of 0°, 5°, 10° and 15°.
