Abstract

PURPOSE:To prevent the deterioration in operation arising from a decrease in fluoride and to decrease the amt. of the spatters to be generated so that the flowability and removability of slag are improved by specifically controlling the content of SiO2 in a flux in association with the content of a lithium compsn. CONSTITUTION:SiO2 is incorporated at 0.5-6% by weight (hereafter the same) total per total weight of the flux into a steel sheath controlled in total N to <=100ppm and in Si to <=1%. Furthermore, total F is controlled to <=3% and the lithium compsn. consisting of lithium ferrite and >=1 kinds among lithium aluminate, lithium silicate, lithium titanate, and lithium manganate is specified to 10-30% in terms of Li2O. The flux contg. 15-25% Al, 5-10% Mg, 0.5-5% Mn, 0.5-5% Zr, 0.5-3% Ti, and contg. <=1.5% at least one kind of Li metals in the form of Al-Li and Mg-Li at need in addition to the above-mentioned elements is filled into the sheath to attain 12-30% flux rate.
