Abstract
Within the Russian-Turkish collaboration the group of scientists and production workers has improved the technology of steel smelting in the super power DSP-250 electric furnace of MMK-Metalurji steel works. The quality of different types of steel scrap has been analysed in the article. It is established that in melting with the available scrap it isn't possible to provide the content of copper less than 0,25%. It negatively affects on the quality of flat product, in particular cracks on a leaf edge are formed. The given research led to the technology using in charging not less than 25% of firm cast iron that allowed to provide satisfactory quality of cold rolled flat product.
Keywords
