Partial replacement and co-hydration of calcium aluminate cement (CAC) with ladle slag was investigated in this study as a pathway valorizing the reducing economic cost CAC. The impact on physical microstructural properties were analysed using different techniques such mechanical strength test, freeze-thaw, sulfate attack, XRD, SEM etc. Thermodynamic modelling used to predict phase assemblages ...

This paper discusses a simulation study of cyclic production systems with a travelling crane. The scope of the system covers the tipping stands of the hot iron into foundry ladle, stands of desulphurization and stands of converters. Therefore, the first aim of this study is the development of a discrete-event simulation model in a steel industry case, and a simulation software Witness is used f...

The modern state of secondary metallurgy is characterized by the sustainable development technologies that ensure high metal quality reducing number non-metallic inclusions, which closely related to oxygen content in steel after smelting. Therefore, issues regularities distribution between phases at stage, BOF - CCM. Purpose. aim research was determine conditions redistribution dissolved depend...

We apply mathematical modelling to study heat transfer processes during fire refining of blister copper in a ladle-furnace unit. A unit was designed test the technology using bottom blowing bubble mode by gaseous reducing agents (hydrocarbons) and an oxidiser. Mathematical allows properties real process be described based on formalisation physical laws regularities. It proposed use agents, rath...
