Blast furnace (BF) is the most used equipment for production of iron in world. It charged mainly with metallurgical coke and ferrous materials. When descending inside BF, iron-bearing materials start reducing melting other burden This leads to formation so-called primary slags from which final slag formed as descend furnace. Each charge material has a unique effect on total composition BF slag....

This paper presents the methodological basis for creating a model system selecting optimum composition of blast furnace burden, providing required technical and economic performance melting pig iron composition. The implements new systematic approach to modeling processes directed formation blast-furnace melts. Description properties metallurgical systems in different states is based on an orig...

Blast-furnace slag is one of the main by-products produced in process blast-furnace ironmaking. Its metallurgical properties have an important impact on smooth operation and long life blast furnaces. In this paper, activity MgO a CaO-SiO2-MgO-Al2O3 quaternary system was measured using reference-slag method at 1773–1873 K. The effects temperature coefficient Mg Sn were discussed. results showed ...

The problem of the accumulation waste from metallurgical industry in Ukraine, particular, blast furnace slag, has an economic and environmental component. Therefore, main problems, first all, include absence a criterion for greening industrial sector among priorities Ukraine's policy. article examines situation slag summarizes existing experience using slags as technogenic raw materials. proble...

At the blast furnace of PJSC “Magnitogorsk Metallurgical Plant” (MMK), specific consumption coke was reduced by impact on thermal reverse zone (TRZ) increasing natural gas above 120 m 3 /t cast iron under conditions increased reactivity and hot strength coke. In first pair periods, an increase in CRI from 38.4 to 39.3 % with a decrease CSR 36.3 34.6 accompanied ratio total oxygen entering 0.43 ...

The process of metallurgical equipment information space is complex and diverse, including multi-level spatial information or spatial process factor. How to divide the metallurgical equipment information space, to plan its communication path intelligently and to enhance the level of intelligent equipment has become one of the metallurgical equipment systems’ problems needing to be resolved. Aim...

The new Kennecott Utah Copper smelter, started in 1995, was designed to be the cleanest smelter environmentally in the world. The plant is operating at production rates above the original design capacity. Copper concentrate is smelted in an Outokumpu flash smelting furnace. Matte is granulated and processed using Kennecott-Outokumpu flash converting. Copper anodes are processed in a modernized ...
