Problems solved by technology

However, domestic smelting flux manufacturing has problems such as serious resource consumption, high cost, serious pollution, relatively unstable process performance and mechanical performance of products, especially some high-grade ore raw material resources are in short supply.
Because the traditional manganese-silicon type smelting flux requires high-grade manganese ore (more than 35% MnO) as raw material, but my country's manganese ore resources are relatively scarce, and a large amount of toxic and harmful gases are emitted during the production process, causing certain harm to the environment. Thereby severely restricting the mass production of smelting flux

Abstract

The invention provides an automatic submerged arc welding flux and a preparation method of the automatic submerged arc welding flux. The preparation method of the automatic submerged arc welding flux comprises the following steps that: industrial residues which contain beneficial elements of a certain grade are mixed with a specific proportion and taken as main raw materials of the automatic submerged arc welding flux, and then placed into a melting furnace for melting; after the raw materials are meted to liquid state, hypervalent manganese ores are added for restoring and color matching, after the water cooling and granulation, the semi-finished products of the welding flux is produced; the melted semi-finished products of the welding flux are dried, screened and packaged, and finally the finished products of the welding flux is produced. The automatic submerged arc welding flux comprises the following components in percentage by weight: SIO233-39%, MnO23-30%, MgO+CaO8-20%, Al2O3+BaO10-15%, Caf22-6.5%, FeO less than or uqual to 2%, S less than or equal to 0.03%, P less than or equal to 0.009%. The automatic submerged arc welding flux has the advantages that the energy consumption is low, the cost is low, the purification of the deposited metal is favorable, the oxidizability is low, the tensile strength is high, and the low temperature impact toughness is high.

Description

technical field [0001] The invention relates to the technical field of flux, in particular to an automatic submerged arc flux using industrial waste slag as a regeneration raw material and a preparation method thereof. Background technique [0002] There are mainly two types of submerged arc welding fluxes: smelting type and sintering type. Since smelting flux has irreplaceable advantages in use, our country currently mainly produces and uses smelting flux. However, domestic smelting flux manufacturing has problems such as serious resource consumption, high cost, serious pollution, and relatively unstable process and mechanical properties of products, especially the shortage of some high-grade ore raw material resources. Because the traditional manganese-silicon type smelting flux requires high-grade manganese ore (more than 35% MnO) as raw material, but my country's manganese ore resources are relatively scarce, and a large amount of toxic and harmful gases are emitted duri...
