This course doesn't talk about 2 major aspects of steel making:

1. Reheating gas furnace and 2. melting of scrap metal in induction melting furnace.

It was good learning experience for me . I thank you to the instructor and coursera.

The course contains a vital information about making steel an iron.

But the accent of the teacher is a bit bad, anyway it's a great course

Very informational for people who want to have a basic grasp of ferrous technology.

Great, introduction into ferrous metallurgy for non-specialists. I had some basic background on the steel industry, but this course nicely tied it together and allowed me to confirm what little I knew and to dispel some misconceptions I still had.

The course could have been a bit longer and a bit more technical, while taking care to ensure that non-specialists can still follow the course.

The course is excellent for metallurgical engineers, the way of teaching is beautiful. thank you all.

we need some distance B.E the same type course, better for all metallurgical under graduate engineers who ever is doing job.

A very useful course that gave me a lot of new information

Excellent, it makes my time grateful, that i spend it to learn about 'Ferrous Technology'. A short course that nearly covers all information about steel making.

Nice course, well explained as it kept me interested. Now, I would like that you can do another course where you can go deeper and interactive, as using some problem solving exercises. Thanks for the course.

Simple and concise, The only issue is Korean accent.
