Transient heat transfer during initial stages of steel scrap melting

The rates of dissolution of solid pure iron in carbon saturated liquid iron were investigated under nonisothermal conditions. Solid cylindrical specimens were preheated to various temperatures below the liquid bath temperature prior to immersion. The effects of heat transfer were evaluated, including freezing of a carbon-rich iron crust on the specimen which subsequently remelts. An analytical model for the process is derived and the numerical solution is compared with experimental results.
