Abstract
The invention discloses a double-phase stainless steel electric welding bar, and relates to the stainless steel electric welding field of electric arc welding. The invention provides a novel titanium-calcium type double-phase stainless steel electric welding bar, which has good welding performance such as little splash, low cost, good slag removal performance and the like. The electric welding bar is characterized in that: according to the coating formula, the electric welding bar comprises the following components in part by weight: 35 to 38 parts of rutile, 8 to 10 parts of natural mica, 1 to 2 parts of potassium titanate, 5 to 7 parts of marble, 10 to 12 parts of iron powder, 1 to 2 parts of bentonite, 2 to 3 parts of electrolytic manganese, 3 to 5 parts of fluorite, 1 to 2 parts of potassium feldspar, 1 to 2 parts of sodium alginate, 2 to 3 parts of chromium nitride, 20 to 24 parts of chromium metal, 8 to 10 parts of ferromolybdenum, 2 to 4 parts of magnesite, 2 to 4 parts of nickel powder and 1 part of Teflon. The welding process performance of the stainless steel welding bar is improved, and particularly the application range of the stainless steel welding bar is enlarged during welding, so the double-phase stainless steel electric welding bar has good welding performance such as good electric arc stability, little splash, low cost, good slag removal performance and the like.
Description
Affiliated technical field
The present invention relates to a kind of stainless steel welding electrode that is used for arc welding.The invention provides a kind of novel lime-titania type stainless steel double-phase stainless steel electric welding bar, make it have good, little, the good welding performance such as cost is low, deslag performance is good of splashing of arc stability.
Background technology
Along with the fast development of metal manufacturing and stainless steel industry, also very high to the product technology requirement of the used welding rod of welding procedure.In the present stainless steel technology, present domestic double-phase stainless steel electric welding bar prescription adopts rutile substantially, calcining mica, chromic carbide iron, calcium alginate, fluorite, marble, CMC, wollastonite, potassium alginate, raw material such as molybdenum-iron.Because there are defective in the prescription and the selection of existing lime-titania type stainless steel welding electrode, have following deficiency in practical engineering application; Arc stability is poor, and spark splashes greatly, and deslag performance is poor, body counted by iron and physicochemical property is bad, arc stabilizer in particularly filling a prescription etc. can't replace, and causes domestic existing diphasic stainless steel electrode can't use aspect numerous engineerings at present, and the overwhelming majority adopts external import diphasic stainless steel electrode.
Summary of the invention
In order to solve above-mentioned technological deficiency, overcome the deficiency of domestic existing double-phase stainless steel electric welding bar, the invention provides a kind of novel lime-titania type stainless steel double-phase stainless steel electric welding bar, make it have good welding performance, it is little to splash, and cost is low, and deslag performance is good, improve the welding technological properties of stainless steel electrode, particularly enlarged the range of application of diphasic stainless steel electrode in welding process.
The present invention solves the technical scheme that its technical problem takes: by analysis and research welding technological properties and physical characteristic, and through formula test repeatedly, the following chemical coating of welding electrode prescription of selected employing (weight proportion meter)---rutile 35-38, natural mica 8-10, potassium titanate 1-2, marble 5-7, iron powder 10-12, bentonite 1-2, electrolytic manganese 2-3, fluorite 3-5, potassic feldspar 1-2, sodium alginate 1-2, chromium nitride 2-3, crome metal 20-24, molybdenum-iron 8-10, magnesite 2-4, nickel powder 2-4, teflon 1 etc.Be mixed into welding rod crust spice by proportioning, with addition of low viscous waterglass, being coated with shoe through electrode extrusion press is the welding rod base at H00Cr21Ni10 special-purpose steel core wire, and drying machine drying and shaping again is made for the welding rod of various specifications such as diameter 2.5mm, 3.2mm, 4.0mm, 5.0mm.
The present invention adjusts and improves lime-titania type stainless steel welding electrode coating recipe and material selection, has made the welding rod of new component structure.Electrode coating of the present invention mainly is to improve coating intensity and arc stabilizer protection, cools off weld seam fast with slag.By adjusting the composition of arc stabilizer, slag former in the coating, form stable electric arc reaction, thereby improved deslag performance greatly.Prescription is selected an amount of potassium titanate for use.Increase crome metal and iron powder, can improve the deposition efficiency of deposited metal, the improvement foot of mica makes electric arc reaction softer in order to improve the intensity of coating, and it is littler to splash, and it is easier to take off slag, and cost is lower, and coating intensity is very good.Because contain an amount of silicon and calcium in the prescription, guaranteed the slag making function, add teflon and can allow the extrusion manufacturing process performance of medicinal powder good, processability is stable, splashing high-volume in the time of reducing welding again.
The specific embodiment
The invention will be further described below in conjunction with specific embodiment
The embodiment of the invention:
Welding rod raw material ratio (by weight)
| The raw material title | Weight | The raw material title | Weight |
| Rutile | ??78 | Electrolytic manganese | ??5 |
| Natural mica | ??19 | Fluorite | ??9 |
| Potassium titanate | ??4 | Potassic feldspar | ??4 |
| Calcite | ??14 | Sodium alginate | ??1 |
| Iron powder | ??23 | Chromium nitride | ??6 |
| Bentonite | ??3 | Crome metal | ??45 |
| Molybdenum-iron | ??20 | Magnesite | ??7 |
| Nickel powder | ??7 | Teflon | ??1 |
Carry out proportioning according to last surface compositions, raw material are stirred as requested add suitable quantity of water glass again and stir, then the medicinal powder that stirs is coated with pressure by hydraulic press at H00Cr21Ni10 special stainless steel heart yearn, dry about 24 hours drying in the shade, through after the check, can be made into the welding rod of different size at last.
Because the present invention adopts such scheme, show that through proof test repeatedly it is attractive in appearance that it has welding fabrication, it is little to splash, and it is easy to take off slag, and welding efficiency is high, and welding performance is good. Particularly weld metal contains the ferrite about 40%, and weld metal has the combination property of austenitic stainless steel and the stress corrosion resistant characteristic of ferritic stainless steel, becomes a kind of brand-new material that petrochemical industry is used. Should can weld by anti-large electric current by the prescription double-phase stainless steel electric welding bar simultaneously, cost is lower, has reduced again welding fume and dust, has more had the advantage that replaces external product, and very outstanding economic benefit and social benefit are arranged simultaneously.
