Detailed physico-chemical studies have recently been made on many important phenomena occurring in the steelmaking furnace. It is, however, desirable to consider all the operations used in the process as a whole, in order to see whether these operations are really necessary and sufficient in their mutual correlations. Standing upon the standpoint mentioned above, the author analysed physico-chemically these mutual correlations of the entire procedure in the open hearth process. As examples, data obtained from a practical acid open hearth process were used. As the result of it, it becomes clear that the open hearth process now successfully applied is generally reasonable to remake massively steel scrap by means of melting process. The result of these analyses will be successively reported. In this first report, the objects of the remelting proccess of steelscrap are discussed. That is : - (1) The steel bath has to contain finally standard amount of Si, Mn, C uniformly mixed (2) has to have neccessary temperature, (3) its O content has to be kept in such amount as to be able to be removed with deoxydizing agents (4) it has to be not gasious (5) the slag contacting with it has to have less oxydising ability.
