Abstract
The invention discloses sintered flux high in flexibility. The sintered flux is made of, by weight, 6-11 parts of lithium, 2-4 parts of chrome, 6-9 parts of MnO, 10-15 parts of CaF, 2-7 parts of Si-Fe, 8-13 parts of Al2O3, 7-9 parts of environment-friendly organic solvent other than fluorine and chlorine type, 1-4 parts of SiO2, 6-9 parts of bismuth oxide, 2-5 parts of potassium sodium water glass, 3-4 parts of citric acid, 2-7 parts of potassium permanganate powder, 1.2-3 parts of modified rosin, 2.2-6 parts of benzimidazole and 2-5 parts of silica micro powder. The sintered flux has the advantages that the sintered flux has good flexibility, meanwhile, the use amount is little, slag shells are thin, and the environmental pollution is reduced.
Description
Technical field
The present invention relates to a kind of sintered flux of high tenacity.
Background technology
Along with the development of modern industry, the raising of automatization level, Lincoln weld, because of the feature that its automaticity is high, speed of welding is fast, Weld Performance is stable, is used widely in the large welded structures such as pipeline, boats and ships, boiler, pressure vessel are produced.Sintered flux is a kind of high-quality, efficient, energy-saving and environmental protection type solder flux.This solder flux weld time smokeless, tasteless, without arc, without splashing.Manufacturing process non-environmental-pollution, energy consumption is low, and raw material utilize fully, meet national industry development policies.The basicity value adjusting range of sintered flux is large, goes for the material welding that solderability is poor, can meet the physicochemical property requirement of weld seam ultralow-hydrogen low, high-strength and high ductility, high cleanliness, be widely used in the welding of the high-alloy steel such as high-strength steel, stainless steel structure.Therefore, sintered flux is the developing direction of following welding.
Summary of the invention
For the deficiencies in the prior art, the problem to be solved in the present invention is, provides a kind of sintered flux, has good toughness, and consumption is few simultaneously, and skull is thinner, reduces environmental pollution.
For solving prior art problem, technical scheme provided by the invention is, a kind of sintered flux of high tenacity, and it is made up of the raw material of following parts by weight:
Lithium 6-11 part, chromium 2-4 part, MnO6-9 part, CaF210-15 part, Si-Fe2-7 part, Al2O38-13 part, non-fluorine chlorine type environmental protection organic solvent 7-9 part, SiO21-4 part, bismuth oxide 6-9 part, potassium-sodium water glass 2-5 part, citric acid 3-4 part, potassium permanganate powder 2-7 part, modified rosin 1.2-3 part, benzimidazole 2.2-6 part, SILICA FUME 2-5 part.
The invention has the beneficial effects as follows: sintered flux of the present invention, have good toughness, consumption is few simultaneously, and skull is thinner, reduces environmental pollution.
