PRODUCTION OF CRUDE FERRONICKEL FROM SIVRIHISAR LATERITE ORES OF TURKEY
KESKİNKILIÇ, ENDER; Pournaderi, Saeid; Geveci, Ahmet; Topkaya, Yavuz Ali (2013-03-07)
In the current work, laboratory-scale smelting experiments were conducted using Sivrihisar laterites (1.26% Ni). The ore samples previously subjected to drying, calcination and prereduction stages were smelted in alumina crucibles in a horizontal tube furnace under argon atmosphere. For the smelting system used in the present work, 1550 degrees C and 40 minutes were determined to be the optimum smelting temperature and time, respectively. 25% excess coal addition in prereduction stage was reported to be cru...

Production of high sulfur forging steels at Çemtaş steel plant
Gitmez, Cenk; Sevinç, Naci; Department of Metallurgical and Materials Engineering (2003)
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 ...
