Metallurgical and Materials Engineering
(2004)
The main fields of operation for Metallurgical and Materials Engineering are production of engineering materials, defining and improving their features, as well as developing new materials to meet the expectations at every aspect of life and the users from these aspects. Founded in 2004 and graduated its 10th-semester alumni in 2018, our Department also obtained MÜDEK accreditation in the latter year. Offering the opportunity to hold an internationally valid diploma through the accreditation in question, our Department has highly qualified and experienced Academic Staff. Many of the courses offered at our Department are supported with various practice sessions, and internship studies in summer. This way, we help our students become better-equipped engineers for their future professional lives. With the Cooperative Education curriculum that entered into effect in 2019, students may volunteer to work at contracted companies for a period of six months with no extensions to their period of study.

Abstract

The feasibility of ferronickel production from a low-grade limonitic laterite ore was investigated. The ore was first calcined and then prereduced in the solid state. The reduced ore was then smelted to produce ferronickel. The effects of coal addition, smelting temperature, and retention time on the process were investigated. Chemical and physical losses in the slag were separately quantified. Coal addition was the main parameter that controlled the ferronickel grade and losses in the slag. The melting point of the slag was well below that of the ferronickel, which enhanced metal-slag separation and minimized physical losses in the slag. A microstructural study of an industrial slag revealed that Cr-rich particulates, which were suspended in the slag, were mainly responsible for the physical losses in the slag.
