JAWAHARLAL NEHRU TECHNOLOGICAL UNIVERSITY HYDERABAD

Course Objective

The prime objective of the course is to make the students understand

various ferroalloys applied in ferrous metallurgy. The furnaces used for production, and the present status and future scope of the ferroalloy industry in India are also dealt as an integral part of the course.

Course Outcome

Acquiring knowledge on the course, the student will be able to select the

required ferroalloy for a specific ferrous alloy to bring out quality yield.
