With maximized scrap charging, especially low quality steel scrap, together with HIsarna ironmaking, the steel company wants to substantially reduce the primary raw material consumption and increase production of high quality products from scrap. The project aims to better understand the dynamic melting and refining behavior of scrap in complex shapes and sizes together with blast furance and HIsarna hot metal; to develop a DEM-CFD based scrap charging, melting and refining model for the converter process; to validate with plant data and provide the theoretical and practical guidance to reach the above goals. The outcome of the project will be used to widen the raw materials and operating window of scrap addition to the state-of-the-art oxygen steelmaking converters; to maximize the usage of lower quality scrap from the scrap market, without compromising the steel quality and process stability; to implement optimized scrap charging strategies to the converter operation; and finally to increase the recyclability of the lower quality scrap and further reduce CO2 emissions in the steelmaking process.
The research will be conducted at the research group of Metals Production, Refining and Recycling (MPRR), Department of Materials Science and Engineering of TU Delft, in close cooperation with our industry partner Tata Steel in IJmuiden (Netherlands).
We are looking for an inspiring, self-motivated candidate to conduct the research defined in the project “Max-SCORE”, for scrap flow, packing and melting behavior under the influence of hot metal charging in the steel converters. For this PhD position, demonstrated knowledge and skills in process modelling and simulation for metallurgical processes, in particular, the experience in DEM and/or CFD modelling are essential. You will work in close collaboration with industry and academia. You are expected to have good communication skills in English and be a team player as part of the MPRR group. Publications in the relevant field by using CFD and DEM, and working experience in steelmaking and metallurgical industry are with added value.
