(1)BG-SJ101G high-speed sintered fluxes:
     BG-SJ101G is one kind of alkaline sintered fluxes, the alkalinity is 1.7, graininess with grey color, the granularity is 10-60 mesh, and the apparent density is 1.20-1.30g/cm3. It belongs to metallurgy neutrality. Silicon and manganese shall not be basically added to weld seam structure when use BG-SJ101G welding flux. This flux has fine process performance, the maximum applicable current is 1200A, it is mainly used for submerged arc welding of X52, X60, X65 and X70 steel pipes, the maximum welding speed is 2m/min.
