The course consists of three modules which should be taken in sequence in order to complete the full course.
Module 1 – Background and Furnace Designs
Module 1 considers the need for reheating as part of the hot rolling of products and describes the most common designs of furnace used on operating plants, highlighting the advantages and disadvantages.
Module 2 – Reheating Furnace Operation
Operation of reheating furnaces are considered from how stock is loaded into the furnace, how the heating process for different stock sizes affects the rate heat needs to be input and how heat is transferred to the stock.
Module 3 – Combustion and Environment
The heating process of the stock is considered with respect to the combustion process of the fuel used to generate the heat required in the reheat furnace. The effects of combustion are considered with respect to environmental effects and how efficiency improvements can be made to reduce the environmental impact including fuel substitution.
