Abstract [en]

This bachelor thesis is performed at Sweden's leading steel company,

SSAB. It is performed at SSAB in Oxelösund at their mills. The aim is

to identify the types of plates that are discarded the most because

of failed flatness, finding the possible factores why they have not

been rescued and make suggestions for improvement.

The studies have been perfomed with qualitative and quantitative

methods to get the best possible understanding of the problem. With

help of data collection, brainstorming, interviews and observations,

the study has been possible to implement, results have been reported

and improvement proposals have been developed.

Improvement suggestions have been given for the SX70E – 20mm plate. A

flow chart have been developed to show how this sorts of plates must

be controlled if the flatness is not approved. The detemined

processes must be changed to processes that, shown by both statistics

and tests, improves the flatness of this types of plates.
