Abstract:
The reactions taking place in mould cavity is one of the most elaborated topics of foundry. Physicochemical reactions occurring between solidifying stainless steel and green sand mould have been experimentally studied. The experimental work essentially consists of collecting burnt sand from the surface of the casting and analysing it. From the products and composition of the burnt sand, the electrochemical nature of the chemical reactions taking place at the steel mould interface during solidification is being theoretically elaborated. The stainless steel having the compositions carbon, 0.280.416, silicon, 0.15 max; manganese, 196 (max), chromium 12-106; nickel, 896 (max), was taken in a ladle of 40 kg capacity lined with dolomite, pre-heated with the ordinary natural gas flame for about 75 min and was cast in the moulds of different composition.
