Process Model based Software System for Steel Reheating Furnace for Energy Efficiency, Quality and Productivity

摘要

The production and manufacturing of steel in integrated steel plants involve various high temperature and energy intensive processes. Due to the high cost of energy and fuel, along with the problems like pollution and green house gas emission; it is imperative that steel industries are striving for energy efficiency. To achieve this, detailed mathematical models are developed to simulate the process and evaluate the optimum process parameters for higher energy efficiency, quality and productivity. Steel manufacturing process involves melting, refining and solidification of steel to produce ingot casting, or continuous casting products like slab, bloom or billets. The steel ingots or concast products are then reheated to 1100-1250 C in energy intensive furnace for further thermomechanical processing like rolling, forging, extrusion and wire drawing. To analyze the energy intensive and large scale steel reheating furnace, mathematical models are developed based on first principles involving heat transfer and phase transformation. The process is then simulated to evaluate the optimum process parameters
