An investigation has been made on the influence of melting conditions on the properties of iron melted in coreless induction furnace. Important properties of iron such as tensile strength, hardness, bending strength and chilling tendency were determined as a function of holding time, melt temperature, types of furnace lining and innoculation. The following results were obtained. (1) Mechanical properties of iron are very much dependent on the melting conditions, particularly on the holding time. It has been shown that the strength of iron is greatest at the beginning of holding. (2) The chilling tendency becomes more apparent by holding at a higher temperature, using rusty raw materials and by the dissolution of the neutral lining. (3) These results are correlated to the change in nitrogen content and the number of eutectic cells of iron. Therefore, it might be concluded that these two are the most important factors influencing the properties of iron.
