| Abstract Scope |
Mitigating supply chain constraints via additive manufacturing for large-scale renewable energy industry components requires both high deposition rates and low-cost feedstocks. Electroslag processing technology using low-cost feedstock consisting of Direct Reduced Iron (DRI) and ferroalloys is a potential route to high throughput deposition. The aim of this work is to understand the feasibility of this process to produce high purity iron and steel alloys by leveraging thermo-mechanical-chemical modeling and physical simulations. To assess the refining abilities, we heat different combinations of DRI, ferroalloys, and commercial fluxes in a tube furnace using Gleeble. We operated the system under varying processing conditions spanning the electroslag welding conditions, e.g. temperatures of ~1800 – 2000 ⁰C and timescales on the order of seconds. We quantitively compared the volume fraction of iron/steel alloys and slag, and their respective elemental composition with the CALPHAD thermodynamical models prepared under the similar experimental processing conditions and material compositions. |
