During the casting of metals at the interface between metal and mould, or contact surface metal-mould, some chemical reactions occur. Reaction products penetrate or move toward the mould as well as toward the castings. In this work the chemistry at the contact surface between the metal and mould was studied. The objective of the work was better understanding of the chemical reactions that occur, at the interfaces, during the casting processes. All experiments were performed, both, on a laboratory and industrial scale, using the steel samples DIN G-X 120Mn 12, the steel samples came from the steel casting industrial plant production list. The moulds were made using the CO2 procedure. Some active components were added to the mould mixture. During the casting process, while liquid metal enter into the mould vacancy, a kind of intensive reaction of liquid metal with quartz sand and added active components occur thus forming a new chemical compounds. These Compounds have an important influe...nce on the steel castings quality, and consequently on the production economy.
