The composition of the exhaust gases from the converter process allows us to judge the degree of absorption of oxygen from the blast, the burnout of metallic iron from the matte and other features of the development of physical and chemical transformations in the converter bath...
In 1971, employees of the NMMC GMOITs proposed a technology for converting mattes without adding siliceous fluxes, which, according to the authors, would reduce the output of converter slags and, in the future, process them with iron extraction...
Sands of a number of titanium deposits contain, in addition to ilmenite -FeO-TiO2, significant amounts of siderite FeCO3. During enrichment, ilmenite and siderite are separated, sending the siderite concentrate (SC), containing part of TiO2 and impurities, to the dump, and the iron-titanium concentrate (ITC) to the electric smelter for titanium slag ...
One of the most important structural elements of the unit for continuous conversion of matte to the method of LGI - “Gipronickel” is the unit of blast supply to the melt ...
One of the directions of improvement of pyrometallurgical processing is the creation of multi-chamber units, in separate chambers of which different characteristic processes are carried out. Such combined units of ore smelting and slag depletion, conversion and depletion, smelting, conversion and depletion have been developed in recent years in the USSR and abroad ...
The method of slag depletion by filtration through a layer of lumpy reducing agent has been known for a long time and tested in various conditions, but it has not found industrial application, because for effective depletion requires too thick layers of reducing agent. There is an established opinion that at depletion of converter slags the filtration method is suitable mainly as the first, preparatory, stage (magnetite destruction), which does not give significant advantages over the exhausted technologies of depletion ...
В основу разрабатываемого Ленинградским горным институтом совместно с институтом Гипроникель процесса непрерывного конвертирования положена верхняя продувка штейновых расплавов в стационарном агрегате ...
The use of material balance equations is the basis of numerous methods of analyzing and calculating metallurgical processes. However, such equations are quite insufficiently applied in the preparation of experimental balances.The present paper deals with the method of obtaining indicators of material distribution in the metallurgical process on the basis of their compositions obtained experimentally. It involves the preparation of balance equations of several chemical elements in the form linking the compositions and quantities of materials, and solving the system of such equations by the usual algebraic methods.A partial variation of such a method was used, for example, by V. A. Bogolyubov. In this case, the task of obtaining a more general formulation of the ...
