摘要： PROBLEM TO BE SOLVED: To provide a flux cored wire for gas shield arc welding, which flux cored wire can prevent the intrusion of diffusible hydrogen into a welding portion in arc welding, and has excellent moisture absorption resistance, and shows excellent welding workability. SOLUTION: The flux cored wire for gas shield arc welding is formed by filling a steel outer shell with flux. The flux contains 4.0 to 8.0 mass% of titanium dioxide, 0.02 to 0.40 mass% of alkaline metal fluoride (in terms of fluorine), 0.02 to 0.40 mass% of PTFE (in terms of fluorine), 0.01 mass% or less of alkaline earth metal fluoride in terms of fluorine by mass% based on the total mass of the wire, and also the rate of the fluoride composed of alkaline metal fluoride and PTFE satisfies the following expressions; (amount of alkaline metal fluoride in terms of fluorine)/(amount of PTEE in terms of fluorine)≤1; and (amount of alkaline metal fluoride in terms of fluorine +0.35)/(amount of PTEE in terms of fluorine)≥1.

摘要： PURPOSE:To increase grain strength and to prevent the generation of dust at the time of casting work by specifying the grain size of granulated powder and the size of pores in the granulated powder, respectively. CONSTITUTION:A flux for continuous casting is prepared by forming a mixture of flux material and water glass binder into slurry state and then drying and granulating this slurry into a state of spherical granulated powder. This flux is a spherical granulated powder in which grains of 100-500mum grain size comprise >=95wt.% of the granulated powder and which has no pore having a size exceeding 20% of the grain size. By this method, a high quality cast billet uniformized in components and excellent in melting property and heat retaining property is produced.
