Abstract
The present invention relates to a low-alloy steel high-toughness self-shielded flux-cored wire. Its flux ingredients are (wt%) 10-30% of CaF2, 25-40% of TiO2, 5-15% of CaO, 5-15% of MgO, 5-15% of Al-Mg alloy, 5-10% of Fe3O4, 5-10% of Mn, 0.5-2.5% of B2O3, 0.1-6% of Ni powder, 1-5% of zircon sand, 1-5% of Li2O, Re is less than 2%, 3-50% of dust iron. Besides, it also may contain one or several kinds of 1-5% cryolite, 1-3% of LiF and 1-5% of manganese ore powder. When welding, its weld fume and toxicity are less, arc is stable, spatter particle is small and its spatter loss is low, welded appearance of is beautiful, and slag can be self-released after flat-plate welding or groove welding and its tae of weld has no viscous slag.
Description
The present invention relates to a kind of high-toughness self-protection flux-cored welding wire that is applicable to low-alloy steel.
Self-protection flux-cored wire is a kind of novel, high-efficiency welding material, but at present domesticly still can not produce, the complete dependence on import of product, and it costs an arm and a leg.External existing self-protection flux-cored wire prescription, content of fluoride is higher.All account for medicine core weight more than 40% as fluoride total amount in United States Patent (USP) 3767891,4186293 and 4551610.Increased the harmful substance in the weld fumes, welding wire spatter particle is big on the other hand, amount is many, has increased postwelding cleaning work amount.
In order to improve processing performance and the mechanical property of low-alloy steel with self-protection flux-cored wire, reduce weld fumes and toxicity thereof, developed this high-toughness self-protection flux-cored welding wire.This welding wire medicine core prescription has adopted the good novel C aF of processing performance
2-TiO
2-MgO slag system utilizes the nitrogen fixation of titanium in weld seam and the malleableize effect of Ti-B-Ni alloy system, has set up the neutral slag system medicine core prescription of subfluoride.
The medicine core of welding wire is big with domestic amount, be easy to get, cheap mineral powder and metal and alloyed powder are raw material, it is characterized in that containing by weight: 10～30%CaF

2O, Re＜2%.3～50%Fe powder.Also can contain following one or more compositions in the medicine core:
Ice crystal: 1～5%, LiF:1～3%, manganese ore powder: 1～5%.
When adopting high-toughness self-protection flux-cored welding wire of the present invention to weld, weld fumes and toxicity thereof are very little, arc stability, and the particle that splashes is little and amount is few, and figuration of bead is attractive in appearance, and it is easy that the interior postwelding of flat board or groove all takes off slag, and welding toe does not have the dry slag phenomenon.During by Unite States Standard ANSI/AWS5.29-80 welding, the mechanical property of deposited metal is:
σ
s＝500～520MPa，σ
b＝570～600MPa，δ＞24.0％，＞60.00％，A
kv(0℃)＞110J，A
kv(-40℃)＞50J。
Embodiment: fluorite 28%, rutile 3O%, marble 8%, magnesia 6%, lithium carbonate 2%, aluminium-magnesium alloy 10%, mid-carbon fe-mn 4%, iron sand 5%, rare earth silicon 1%, nickel powder 2%, ice crystal 2%, iron powder 4%.
Can adopt H08A and H08A1 cold-rolled strip as flux-cored wire jacket, medicinal powder filling rate 20～30%.
