Program for the two-week pre-course

The 18th Course on Fundamentals and their Application in Aluminium Production

 

CONTENTS OF THE COURSE 2014
There has been a request from aluminium smelters for a more basic education and a more detailed introduction to aluminium electrolysis technology than it is possible to give during the one-week course: "The International Course on Process Metallurgy of Aluminium." As a response we are offering a two-week course in fundamentals and their application in primary aluminium production. The course will contain fundamental topics and thorough understanding through lectures, written exercises, laboratory
demonstrations and practical application to industrial problems.

The course is aimed at people working or starting in the primary aluminium industry, but is also useful for freshmen and for people working in related fields, who want to know more about aluminium production technology. This course is also very
suitable as a preparation for participation in the following one-week course.

The course material, which will be available on the first day of the course, includes the book: "Introduction to Aluminium Electrolysis" by K. Grjotheim and H. Kvande (Editors), as well as complete lecture notes. The course language is English.

AIM OF THE COURSE
The aim of the course is to give the participants theoretical and practical knowledge necessary for their daily work. Group work and group discussions will be important parts of the course and require active involvement of the participants. Experience from previous courses has shown that the opportunity of discussing practical problems with colleagues from other companies is greatly appreciated. The participants are encouraged to bring with them a problem or two that they would like to discuss in class during the course.

TIME AND PLACE
The course will be held at the Norwegian University of Science and Technology, Trondheim, Norway, in the Chemistry Auditorium 5. There will be a bus pick-up from the hotels each morning. An excursion to Hydro Aluminium Sunndal Plant will be arranged on Wednesday, May 28 That means duration of the course is 9 days, including the excursion.

The university campus is located about 20–30 minutes walk south of the downtown area. The course will start each morning at 08:30.

ENROLlMENT AND FEE
The participation  fee is NOK 22.500. The fee covers course materials, the excursion to the Hydro Aluminium Sunndal smelter, lunches, beverage breaks, a course dinner, but no board or other meal expenses. Breakfast is included in the hotel price. An extra discount of NOK 1000 if paid before April  1, 2014.

For the participants attending this course it is possible to register for the subsequent
"International Course on Process Metallurgy of Aluminium" at a discount of NOK 2 500.

The application may be cancelled before April 15, 2014 for a refund. Cancellations received after April 15, 2014 are subject to NOK 1000 service charge
