ASPECTS REGARDING THE QUALITY OF CAST IRON PRODUCED IN S.C.FONTUR S.A. SUCEAVA
Journal Title: TEHNOMUS - Year 2011, Vol 18, Issue 1
Abstract
The authors analyze the quality of produced cast iron and molded forms from SC FONTUR SA Suceava. For this purpose samples were cast from different batches of samples, from which were made tensile specimens, samples for chemical and metallographic analysis and hardness control. Based on analysis conducted authors show corrections that have to be made to the chemical composition and of cast iron structure to obtain high mechanical strength. Also they give recommendations on improving technology development.
