Electric arc furnace dust (EAFD) is generated in considerable amounts by the electric arc steelmaking process. During melting in an electric arc furnace, certain elements volatilize, and form fine dusts after cooling. The EAFD is collected in a baghouse and amounts to approximately 1–2 wt% of the steel produced.1) In China, about 800 million tons of steel was produced in 2015 with more than 9 w...

In modern steelmaking the duration of a working campaign for a blast furnace is related to the life of the crucible. Adding titanium oxide has been a frequent practice in the operation routines for modern blast furnaces, seeking the protection of the crucible walls, independently from its physical or chemical characteristics. These practices, as conventional operation of iron and steelmaking in...

Gas utilization ratio (GUR) is an important indicator that is used to evaluate the energy consumption of blast furnaces (BFs). Currently, the existing methods cannot predict the GUR accurately. In this paper, we present a novel data-driven model for predicting the GUR. The proposed approach utilized both the TS fuzzy neural network (TS-FNN) and the particle swarm algorithm (PSO) to predict the ...
