The paper presents the analysis and investigation of the state of art in the field of metallurgy copper alloy in the reduction conduction. This article contains information concerning the analysis of the possibility of defining refinery qualities of slag based of the thermophysical and thermodynamical data. The isues presented deals not only with refining copper and melting stages, but also the idea of building an optimization program. In its assumption the program is supposed to check and search specific data very quickly on the particular types of slag. In the presented work it has been decided to show the results of the industrial investigations obtained with reference to copper alloys in the reduced melting conduction.

This article contains information concerning of the analysis the possibility of defining refinery qualities of the slag based thermophysical and thermodynamical data. The paper presents a model of slag refining processes and a method of determining the reduction capability of slag solutions. Slag was analysed with the use of the DTA methods. The study of computer programme including the satisfactory number of data, both thermodynamical how and experimental - gathered with literature and own investiganion, the simpler qualification of optimum proprieties of slags would make possible. Settled by programme of areas the verification it is possible to the end to conduct in the support about proposed by A. W. Bydałek method of the modelling processes of refinement from it utilization the derivatograph or directly in conditions industrial. The isues presented deals not only with refining copper and melting stages, but also of the idea building an optimization program. In its assumption the program is supposed to check and search specific data very quickly on the particular types of slag..User starting programme should have the possibility of choice kind of the information.

Rafinacja kąpieli metalowej w kadzi decyduje o własnościach uzyskiwanej stali. Jednym z warunków jest uzyskanie zawartości siarki odpowiednim poziomie. W artykule zaproponowano model obliczania ilości materiałów odtleniających kąpiel metalową oraz dobc materiałów żużlotwórczych, zapewniających zakładany wysoki stopień odsiarczenia. Realizacja modelu odbywa się poprzez ustalei składu chemicznego żużla rafinującego w kadzi, cechującego się odpowiednią pojemnością siarczkową.

Ladle rafination of steel determines properties of produced steel. One of required conditions is to obtain sulphur content at a adequate lex Calculation model of quantity of deoxidizers and slag forming additions for high desulphurization extent has been suggested. The moi allows to calculate the chemical composition of refining slag exhibiting adequate sulphide capacity.

W pracy przedstawiono wyniki badań nad zastosowaniem nowych reagentów żużli rafinacyjnych w procesach topienia złomów i przetapiania w warunkach odlewniczych. Na podstawie analiz właściwości otrzymywanych stopów dokonano wyboru najkorzystniejszych reagentów dla mosiądzu MO59 i brązu B101.

Apart from high quality brass and bronze, a considerable reduction of melting losses was also observed. The experiments on CuZn39Pb2 brass melting proved that optimum is achieved while using technical carbide, aluminium and as stimulator NaCl with NaF. A refiner of commercial name RZ was introduced to foundry and scrap processing industry. The experiments on CuSn10P bronze melting proved to until conclusion - best is reagent consist with mangan, technical carbide and carbon. This assented as a confirmation of the following foundations that reduction conductions should be chosen on copper alloys deliberately but the essential emphasis should be put on properly elaborated factors of multistage reaction with essential usage of suitable stimulators.
