点がある。<Problems to be Solved by the Invention> In the conventional melting method using a melting type flux, there was a problem in that an arc was not blown between the metal and the furnace bottom at the start of melting, so that the I-scallop at the furnace bottom was accelerated. As a countermeasure to this, there is a method of spreading coke on the surface of the molten flux and blowing an arc between it and the coke, as shown in Japanese Patent Application Laid-Open No. 50-132014. There is a problem that coke remains in the process and reduces product quality.
