Lime Dissolution in Foaming BOF Slag [PDF]
Metallurgical and Materials Transactions B, 2018 Abstract The paper describes the dissolution mechanisms of lime into liquid and foaming slags relevant to the BOF process. Two different master slags are employed, representing two different periods of the converter process: an early stage where the FeO content is fixed to 45 wt pct, and a later stage where the FeO content is fixed to 25 wt ...

Chemie Ingenieur Technik, EarlyView.The steel industry accounts for about 7%‐9% of global CO2 emissions. While H2‐based direct reduction is a long‐term route, near‐term solutions are needed for existing plants. Internal carbon cycles reuse steelworks off‐gases and by‐products, enabling circular carbon use and supporting CCU integration.

Corporate Social Responsibility and Environmental Management, EarlyView.ABSTRACT This paper examines whether occupational pension funds (OPFs) apply a strategic and long‐term logic when assessing ESG practices in their investee firms. Using discourse analysis of semi‐structured interviews with asset managers and workers' representatives, we examine whether Spanish OPFs look beyond compliance‐driven CSR and consider the ...

Physical Model of Slag Foaming.
ISIJ International, 1993 Physical model of slag foaming was developed by using results of cold and hot model experiments. The bubble size at the slag/metal interface, the void fraction of foam and the film life of a bubble at the top surface of slag were calculated. The governing factors of slag foaming have been clarified with this model. It was confirmed that the bubble size

Interfacial phenomena in ironmaking and steelmaking
工程科学学报, 2018 A number of important links in the metallurgical production process are related to interface phenomena, including slag foaming, hot metal desulphurization, refractory erosion, converter blowing, the behavior of inclusions in steel, and so on. Interfacial

Deep Underground Science and Engineering, EarlyView.Based on the 90 datasets, ERT and four optimization algorithms were used to build four hybrid models to predict the UCS of the backfill body. The SMA‐ERT model was the most effective model, and it can reliably guide the design of the backfill ratio parameters. Abstract This study analyzed the feasibility of using titanium (Ti) tailings as a backfilling
