Optimised reheating of semis through high performance automation solutions and precise process controls in reheating furnaces is a key enabler to meet the demands for high quality and low cost hot rolled products.
Tata Steel Automation Division offers you a Level 2 automation system for delivering optimally soaked flat or long semis through furnace temperature control which has a significant impact on the product quality. The system has been developed using in-depth understanding of hot rolling technology and years of experience in developing automation solutions
In hot rolling of steel, the uniform heating of flat or long semis at exactly the right temperature and their timely delivery to the rolling mill is extremely critical to the quality of the rolled products, mill performance and cost of manufacturing. The semis need to be delivered to the mill at the required temperature with minimum fuel consumption and uniform temperature all across.
The zonal temperatures inside the reheating furnace are controlled through set points which need to be determined dynamically to achieve quality heating in various production scenarios. Manually controlling these set points compromises the quality of heating of the semis and therefore the quality of the end product.
Level 2 automation for reheating furnaces is an online furnace temperature control system whose main task is to provide optimally heated steel semis to the rolling mill for various production requirements. It controls the furnace temperature to achieve the required discharge temperature of semis, low oxidation losses, less energy consumption while ensuring the heating quality. The system also provides furnace visualization, furnace health check and web reporting system.
