| Abstract: | Through analyzing the slag of TiO2-CaO-SiO2-CaF2 of basic electrode J507, the influence of the slag and alloy system on fume and wdding procedure was studied. The result showed that basic low fume electrode was obtained through increasing TiO2 and Fe powder,reducing CaF2 and adding Si-Ca alloy to the slag on the basis of guaranteeing welding procedure. The JSO7DF is a new class basic electrode with unique total mount of fume 9.13 g/kg and good welding procedure. Furthermore, other properties meet the national standard for the electrode. |
