Abstract
The invention discloses a surfacing flux special for alloy powder transition strip surfacing. The sintered flux comprises the following components in percentage by weight: 25-30% of aluminum oxide (Al2O3), 22-28% of magnesium oxide (MgO), 8-12% of calcium fluoride, 8-12% of calcium oxide, 5-8% of titanium dioxide, 4-6% of manganese oxide and the balance silicon dioxide (SiO2). The surfacing flux provided by invention has the positive effects that: due to the characteristics of high production efficiency, low comprehensive cost, good welding quality and the like, the alloy powder transition strip surfacing can be used for performing surfacing on common low-carbon steel or low-alloy steel; and by adjusting the class and amount of the transition alloy, deposited metals with different hardness levels can be obtained. The surfacing flux has high slag detachability, realizes flat and beautiful welding bead, ensures small machining allowance after welding and guarantees the welding quality.
Description
Technical field
The invention belongs to field of welding material, the special-purpose built-up welding solder flux of particularly a kind of alloy powder transition strip surfacing.
Background technology
The strip surfacing technology plays very important effect as the technology of an important parts reparation and production wear part in modern industry production.And solder flux is one of main consumable material in the weld deposit process, and its welding technological properties and chemical metallurgy performance are the principal elements of decision welding quality.Technique for overlaying is especially used in the heavy industry field on a large scale at industrial circle, at Ferrous Metallurgy, and the mine, electric power, coal, the big effects of industry play more and more such as machine-building, strip surfacing, is used widely to advantages such as the welding base metal dilution rate are low because the welding efficiency height is arranged.Alloyed powder transition strip surfacing is because the production efficiency height, characteristics such as integrated cost is low, and welding quality is good utilize this technology to carry out built-up welding at ordinary low-carbon steel or low-alloy steel, by the kind of adjustment transition alloy and the quantity of transition alloy, can obtain the deposited metal of different hardness grade.Alloy powder transition strip surfacing solder flux is to welding quality and the same important influence of weldment subsequent treatment, built-up welding solder flux commonly used at present is mainly used in the submerged arc overlay welding of filament, the special-purpose built-up welding solder flux of strip surfacing requires its welding slag that better wetability, appropriate melting point and the good removability of slag are arranged when high temperature, and that these are built-up welding solder flux of using always is unapproachable.
Summary of the invention
The objective of the invention is at above-mentioned existing problems, provide a kind of alloy powder transition strip surfacing special-purpose built-up welding solder flux, adopt that this built-up welding solder flux takes off that slag is easy, welding bead smooth attractive in appearance, postwelding allowance is little, helps guaranteeing welding quality.
Technical scheme of the present invention:
The special-purpose built-up welding solder flux of a kind of alloy powder transition strip surfacing, its sintered flux component is made up of alundum (Al, magnesia, calcirm-fluoride, calcium oxide, titanium dioxide, manganese oxide and silica, and the percentage by weight of its prescription composition is: Al
2O
325-30%, MgO 22-28%, CaF
28-12%, CaO 8-12%, TiO
25-8%, MnO 4-6%, SiO
2Be surplus.
Formulation analysis of the present invention:
Pass through to add multiple oxide in the solder flux, as aluminium oxide, titanium oxide, magnesia, calcium oxide etc., can guarantee welding arc stablility, cause a kind of atmosphere of reduction around electric arc, prevent airborne moisture, pernicious gases such as nitrogen oxide enter deposited metal, the welding slag that generates covers the weld metal surface equably, slowed down the cooling velocity of weld metal, and obtained good bead contour, guaranteed that slag has appropriate melting point, viscosity, density, coating forms slag under the high temperature action of electric arc, a series of metallurgical chemistry reactions take place, and remove oxide and sulphur, objectionable impurities such as phosphorus.Al
2O
3And MgO, can form good welding slag with fluoride, the protection weld metal.Next adds fluoride etc., CaF during welding
2The HF that produces of decomposition, help reducing the dividing potential drop of hydrogen in the arc atmosphere, thereby play the dehydrogenation effect.The used welding material of this project is made of three parts: carbon steel steel band, alloy powder, special sintered flux.
Good effect of the present invention: alloyed powder transition strip surfacing is because the production efficiency height, integrated cost is low, characteristics such as welding quality is good, utilize this technology to carry out built-up welding at ordinary low-carbon steel or low-alloy steel, by the kind of adjustment transition alloy and the quantity of transition alloy, can obtain the deposited metal of different hardness grade.It is easy that solder flux takes off slag, and welding bead is smooth, attractive in appearance, and postwelding allowance is little, has guaranteed welding quality.

2O
326.5%, MgO 26.9%, CaF
29.6%, CaO 9.3%, TiO2 5.2%, MnO 5.2%, SiO
217.3%.
Application feature and effect:
Used welding material is made up of carbon steel steel band, alloy powder and above-mentioned sintered flux, uses alloyed powder transition strip surfacing mild steel welding, alloyed powder wood and prepared sintered flux in the enterprising windrow weldering of Q235 mother metal.Concrete parameter is: carbon steel welding 60*0.5mm, welding current 750A, weldingvoltage 30V, speed of welding 17mm/min, powder feed rate 120g/min, the built-up welding number of plies 2.Result of the test shows: its built-up welding hardness is HRC 57-59, the effect ideal.
