Immediately after start-up, for the first time in Turkey, stainless steel grades 304 and 304L were produced with the aid of the new VOD plant.

For the VOD plant for Colakoglu, Primetals Technologies was responsible for the engineering and supplied all the core components. These included, for example, valve stands, the oxygen blowing lance system as well as filters and a filter cleaning system installed before vacuum pumps. The scope also encompassed the modernization of the existing automation system. The level 2 system including process models was modernized in order to operate the VOD plant. Additionally, all required instrumentation of the equipment was supplied by Primetals Technologies.

Colakoglu operates an electric steel plant in Dilovası, in the west of Turkey. The main products of the plant are slabs for further processing in a hot rolling mill, and billets for producing reinforcing steel bars and steel rock bolt. The Colakoglu steel making plant, one of the largest in the world, was supplied by Primetals Technologies and is in operation for several years. This latest modernization project marks another step in the successful business partnership of Colakoglu and Primetals Technologies.
