Technology for Electroslag Remelting with Rotation of the Consumable Electrode
is known that metal which is produced by the method of electroslag remelting (ESR) has service properties superior to those of metal made by open refining and casting. This can be attributed to the better conditions which exist for refining in the specially chosen slag and for the crystallization of the metal in the case of ESR. However, the need for a two-stage metallurgical conversion (essent...
متن کاملThe Structural Evolution and Segregation in a Dual Alloy Ingot Processed by Electroslag Remelting
The structural evolution and segregation in a dual alloy made by electroslag remelting (ESR) was investigated by various analytical techniques. The results show that the macrostructure of the ingot consists of two crystallization structures: one is a quite narrow, fine, equiaxed grain region at the edge and the other is a columnar grain region, which plays a leading role. The typical columnar s...
متن کاملEffect of Current on Structure and Macrosegregation in Dual Alloy Ingot Processed by Electroslag Remelting
Macrosegregation is a very common problem for the quality control of all cast ingots. The effect of current on the structure and macrosegregation in dual alloy ingot processed by electroslag remelting (ESR) was investigated experimentally with various analytical methods. In this study, the electrode consisted of NiCrMoV alloy bar (upper part) and CrMoV alloy (lower part) with a diameter of 55 m...
متن کاملUtilization of Eaf Metallurgical Slag in “green” Belite Cement
În acest studiu, zgură de cuptor cu arc electric (EAFS) colectată de la Sovel S.A., Grecia şi calcar şi argilă, de la compania de ciment Titan S.A., Grecia, au fost utilizate pentru producerea şi caracterizarea cimenturilor tip belitice. Trei tipuri de clincher au fost preparate: belitic fara adaos de zgură folosit ca referinţă (BC), unul cu 5wt% EAFS (BC5) şi un altul cu 10wt% EAFS (BC10). Ana...
متن کاملOvercoming bureaucratic obstacles to the re - use of metallurgical slag – A South African case study
Metallurgical slag, including ferrochrome slag is internationally recognized as suitable material for use in road construction and as aggregate for concrete (Rossouw et al. 1981, Lind et al. 2001). Contrary to international practice, metallurgical slag – including ferrochrome slagis classified as hazardous waste that must be de-listed before use in other applications (DWAF 1998). Having adopted...
