Abstract

A submerged arc welding flux is made by mixing the dry constituent powders of the flux with water or other liquid in the presence of a binder to produce a crumbly mass, forcing the crumbly mass through a sieve of 5-20 mesh B.S. to form granules and then firing the granules at a temperature below their fusion temperature. The binder, which acts as a granulating agent only and does not promote bonding of the particles within the granules when they are fired, may be organic e.g. gum acacia, gum karaya, gum tragacanth, lignin, tannin, a water-soluble cellulose derivative such as sodium carboxymethyl cellulose, dextrin, starch, sugar, molasses, flour or a pitch or bitumen product; and/or inorganic e.g. a salt of zinc, lead or cadmium, or a chloride, fluoride or carbonate of an alkali or alkaline earth metal. Firing is effected at 800 DEG -1300 DEG C. in a fixed or rotating kiln. Flux constituents disclosed are manganese ore, sand, carbon, calcined fireclay, alumina, ground glass, woolastonite, olivine, ferrosilicon, silicomanganese and potassium silicate. Specifications 803,607 and 847,965 are referred to.
