Thesis Abstract

Abstract
The design and construction of a dual-powered heat treatment furnace is a critical project aimed at improving energy efficiency and flexibility in heat treatment processes. This research project focuses on the development of a furnace that can utilize both electricity and gas interchangeably based on cost and availability. The dual-powered furnace offers significant advantages over traditional single-powered furnaces by providing the ability to switch between energy sources to optimize operational costs while maintaining high performance standards. The design phase of the project involves selecting appropriate materials for the furnace construction, determining the optimal size and layout for heat treatment operations, and integrating dual energy supply systems. Advanced modeling and simulation techniques are employed to analyze the thermal performance of the furnace under various operating conditions. The construction phase includes fabricating the furnace structure, installing heating elements, temperature sensors, and control systems for precise temperature regulation. One key aspect of the dual-powered furnace is its ability to achieve uniform heating and precise temperature control throughout the heat treatment process. This is essential for ensuring consistent metallurgical properties and mechanical characteristics of the treated materials. The furnace design incorporates insulation materials and refractory bricks to minimize heat loss and maintain thermal efficiency. The dual-powered furnace is equipped with advanced control systems that monitor and adjust the heating process in real-time. This enables operators to fine-tune temperature profiles, heating rates, and cooling processes to meet specific heat treatment requirements. The flexibility of switching between electricity and gas allows for cost optimization based on energy prices and availability, making the furnace suitable for a wide range of industrial applications. Overall, the design and construction of the dual-powered heat treatment furnace represent a significant advancement in the field of heat treatment technology. By combining the benefits of electric and gas heating systems, this furnace offers improved energy efficiency, operational flexibility, and precise temperature control for industrial heat treatment processes. The research findings from this project have the potential to enhance the competitiveness and sustainability of manufacturing industries by reducing energy consumption and production costs while maintaining high-quality standards in heat treatment operations.

INTRODUCTION

1.1   BACKGROUND OF THE STUDY

          The modification of microstructures to achieve desired properties is a fundamental approach in metallic materials development. Heat-treatment which is one of the primary routes of developing microstructures requires the use of furnaces to be able to attain desired temperatures, heating and cooling rates; and holding environments required to induce phase transformations (Dossee and Boyer, 1997). Heat treatment furnaces with effective temperature sensing, heat retaining capacity and controlled environment are necessary for heat-treatment operations to be successfully performed. Some of the processes require heating cycles for durations spanning a few minutes to several hours depending of the material and the properties desired (George, 2002; Netsushori, 1998).
