Abstract:
High intensity processes and new furnace designs, as well as adaptations of existing processes (e.g., due to changes in ore quality), present a challenge for metallurgists and equipment suppliers, including refractory producers. The refractory lining is a main factor for safe and economic furnace operation as it provides the main barrier between hot molten phases and the environment - a failure not only can lead to equipment damages, but it also presents a risk for the operating personnel. RHI has been providing high quality refractories and complete lining solutions for ferroalloy vessels for many years. Continuous improvement and development, as well as expert knowledge of metallurgy and equipment, are key factors for dealing with new process and design challenges. The present paper provides an overview of optimization potentials in ferroalloy linings and RHI's approach to providing functional and comprehensive refractory solutions.
