Course Description

This practical and highly-interactive course includes real-life case studies and exercises where participants will be engaged in a series of interactive small groups and class workshops.This course is designed to provide delegates with a detailed and up-to-date overview of roll mills reheating furnace (walking hearth) operation and optimization. It covers the mill layout and reheating furnace (walking hearth); the billets/blooms movement through the reheating furnace, cycle time of walking hearth furnaces and positions of billets/blooms; and the heat balance inside furnace, heat transmission, temperature differences between billets/blooms; and estimation of billet/bloom temperature.Further, the course will also discuss the thermal radiation between billet/bloom and furnace walls; the heat transfer between billets/blooms, the furnace atmosphere and the hearths; the heat transfer coefficient, thermal conduction, thermal properties of materials and specific heat; the emissivity/absorption rate, thermal conductivity and mesh construction; the heat balance modeling in each component, factors from furnace walls, hearths and ceiling to a mesh; the heat transmission between billets/blooms and the hearths; and the local temperature of the hearths and interaction between billets/blooms.
