In these day, Carbon Neutrality is important issue in the world. And iron&steelmaking industry is also undergoing process change to achieve carbon neutrality. The biggest change is process transitions from BF-BOF to DRI-EAF. In case of BF-BOF process, They can produce from normal grade of steel to AHSS grade steel. But this process need to generate so many CO2 emission, 1.85tCO2/steel ton. On...
The transition towards more sustainable steel production implies also huge challenges regarding raw material procurement and usage. Production management for liquid steelmaking has to optimize the raw material input, especially regarding hot metal, DRI/HBI, scrap, alloy and slag former materials. Forecasts of the expected raw material demands in production planning and scheduling support their...
As a typical harmful element in steel, the presence of nitrogen can seriously affect the performance of steel materials. Restricted by raw materials, equipment and process conditions, the nitrogen content of electric furnace steelmaking is high, which cannot meet the quality requirements of high-grade sheets such as automobile sheet and silicon steel. The use of direct reduced iron to control...
A numerical model for the estimation of main variables in Electric steelmaking is presented. The multiplicity of phenomena occurring in the EAF together with the huge number of variables and their complex interaction, prevents the development of a reliable online application able to take direct action on the process. An alternative approach in which the overall average performance of the EAF...
This paper synthesizes five years of simulations across diverse scrap yards, demonstrating how discrete event simulation enhances material flow optimization. The presentation will distill five key lessons, addressing common pitfalls in scrap yard modeling, optimizing scrap pile locations, comparing scrap manipulators, improving bucket handling time and integrating new processing plants. The...
