(1) dry powder is mixed in proportion, waterglass is added and carries out wet mixing and stirs evenly；
(2) mixture stirred evenly in step (1) is granulated；
(3) it is sieved again after the raw material being granulated in step (2) being carried out drying and processing at 400-500 DEG C；
(4) by the raw material being sieving through under 750-900 DEG C of oxidizing atmosphere high temperature sintering 30-60min, be cooled in cooling furnace
35 DEG C or less screening to get.
Further, the size being granulated in the step (2) is 4-40 mesh.
Further, the size sieved in the step (3) is 16-40 mesh.
Further, the size sieved after cooling in the step (4) is 10-40 mesh.
A kind of application of multipurpose steel alloy submerged arc sintered flux, is used for the submerged arc welding of mild steel, low-alloy steel.
Present invention has the advantage that
1. flux composition provided by the invention is reasonable, cooperate suitable sintering condition, by the way that more CaF is added2、Al2O3Based on
It slag former wanted, restrained effectively the harmful elements such as H, O to weld seam transition, so as to improve the surface flatness and skull of weld seam
Removability of slag energy guarantees that the welding quality of commissure, the removability of slag can be excellent；
2. sintered flux produced by the present invention has adjusted the viscosity, surface tension and mobility of slag well, when solder flux welding,
Welding process is stable, fume amount is few, splashing is small, removability of slag energy is excellent；
