This study was undertaken with the objective of determining the operation practice to be followed in production of forging quality aluminum killed steels with high sulfur contents in Çemtaş Steel Plant. Nowadays, many steel grades used in the automotive industry are required both to have improved rracliining characteristics and to be fully killed, Le. deoxidized with aluminum. The product which is manufactured as hot-rolled bars in steelmaking company is shaped with forging process and then, subjected to a high degree of machining. The influences of sulfur, oxygen, aluminum and calcium on the production of this type of steel were examined in terms of castability, machinability, mechanical properties and sulfide morphology parameters.

PRODUCTION OF SILVER LOADED PHOTOCATALYTIC TIO2 POWDERS BY BALL MILLING Aysin, Basak; PARK, JONGEE; Öztürk, Abdullah (2011-09-23) The present study was undertaken to improve photocatalytic efficiency of TiO2 powder by silver doping and/or particle size reduction through mechanical ball milling. A planetary ball mill was employed to reduce the particle size of TiO2 powders to nanoscale and silver loading to TiO2 powders. Silver nitrate was used as silver source to obtain about 1% Ag load. Slurry taken from ball mill was separated by centrifugal separator into nano and micro sols. Separated nanosol was taken into the furnace to be dried...
Production of in situ aluminum-titanium diboride master alloy formed by slag-metal reaction CHANGIZI, Ahmad; Kalkanlı, Ali; SEVINC, NACİ (Elsevier BV, 2011-01-12) Al-TiB(2) master alloys have received much attention in recent years owing to their potential as efficient grain refiners for aluminum foundry alloys. In this study, the process of production of master alloys was investigated to develop a low cost method, namely, slag-metal reaction. This method can be used to fabricate Al-TiB2 master alloy in situ from the TiO(2)-H(3)BO(3)-Na(3)AlF(6) and Al system. Since the price of the raw materials is low and the technology is simple, the processing technique appears t...
Production of heavy-media-quality magnetite concentrate from Kesikköprü iron ore tailings Güngör, Kazım; Atalay, M Ümit; Department of Mining Engineering (2010) The aim of this research was to investigate the possibility of the production of a magnetite concentrate which is suitable for preparation of heavy media from iron ore tailings of Güncem Mining Company magnetic separation facility. During the study, three different tailings named as low grade, medium grade and high grade with 5.91 % Fe3O4, 19.06 % Fe3O4 and 37.06 % Fe3O4, respectively, were used. Mineralogical analyses of test samples showed that magnetite and hematite were the major ore minerals while pyri...
Application of EOR techniques for oil shale fields (in-situ combustion approach) Kök, Mustafa Verşan; Bagci, S. (2008-01-01) In this study, 1-D combustion tube experiments were performed with samples from the Turkish Seyitomer, Himmetoglu and Hatildag oil shale deposits. The results demonstrate that these oil shales are suitable for oil production by in-situ combustion techniques. The calculated production values are 4.46, L/ton for Seyitomer oil shale, 32.22 L/ton for Himmetoglu oil shale, and 18.27 L/ton for Hatildag oil shale.
Simulation of equal channel angular pressing applied to produce structures with ultrafine-sized grains Karpuz, Pinar; Şimşir, Caner; Gür, Cemil Hakan (Inderscience Publishers, 2009-01-01) Severe plastic deformation methods are of great interest in industrial forming applications, as they give rise to significant refinement in microstructures and improvements in mechanical and physical properties. In the 'equal channel angular pressing (ECAP)', which is the most common method for production of ultrafine grained bulk samples, very high plastic strains are introduced into the bulk material without any change in cross section. In this study, the plastic deformation behaviour of the materials sub...
