Metal melting is the process of producing a liquid metal of the required composition at the required rate, and with required amount of superheat while incurring the minimal cost. It is one of the most important foundry practices, as it decides the quality of the casting.
1 Ιαν 2024 · The basic principle of electric steelmaking today is that the furnace is a “melting machine” that produces liquid steel with the required chemistry, temperature, and mass in time to feed steel to successive ladle treatments and continuous caster, which finally determines the production rhythm.
This chapter provides an overview of the types of melting furnaces and refractories for steel casting. It then presents information about arc furnace melting and induction melting cycles. The chapter also describes methods for the removal of phosphorous, the removal of sulfur, and the recovery of elements from slag.
CHAPTER 1. a melting. subliming/sublimation. freezing. subliming/sublimation. a. solid liquid gas. Note: Solids should have regularly packed particles touching. Liquids should have most of the particles touching at least some of their neighbours, but with gaps here and there, and no regularity. Gases should have the particles well spaced.
This article discusses the most common methods of melting steels, namely, electric arc and induction melting. It describes the classification of refractories by an index of the “basicity” of the slag formed on the steel surface.
Inductive melting in steelworks. by Mohamed Chaabet, Erwin Dötsch. After the development of induction technology with inverter outputs of over 40 MW for crucible furnaces with capacities of more than 65 t, the induction furnace offers itself as an alternative to the electric arc furnace.
