Description
Technical field
The present invention relates to technical field of welding materials, and in particular to a kind of mold automatic surfacing gas slag Combined Protection gold
Belong to flux cored wire.
Background technology
Mold is the prodigious a kind of key spare parts of forging industry consumption, is born for a long time higher
Cyclic loading easily fails, and scraps.The length of die life directly influences the efficiency of production, part
Quality and production cost.Currently, generally improving the forging mold service life using gas protecting welding wire built-up welding, gas protecting welding wire is commonly used
There are two types of：
1, using 4.5%~7% quantity of slag gas shielded flux cored wire built-up welding forging mold, 4.5%~7% quantity of slag gas protecting welding wire lacks
Putting is：Every layer of percussion, leads to that efficiency is low and the easy slag inclusion of deposited metal, advantage are：Slag gas joint adequately protects；
2, using no slag solid core gas shield welding wire built-up welding forging mold, no slag solid core gas shield welding wire the disadvantage is that：In welding process only
Pure gas is protected and is protected without slag crust, deposited metal stomata easily occurs；In addition high alloy solid core gas shield welding wire manufacture difficulty
Greatly, the manufacturing cycle is long, and needing can by steel-making → rolling wire rod → wire drawing → annealing and multiple wire drawing → annealing reaches minor diameter
With the solid core gas shield welding wire used.
As stated above, flux-cored wire is more suitable for built-up welding forging mold, but it is low to solve the easy slag inclusion of flux-cored wire, efficiency
The shortcomings that, so the built-up welding for developing micro- slag gas slag Combined Protection metal powder core solder wire for forging mold is imperative.
Invention content
The object of the invention is remanufactured for forging mold robot or numerical control device repeated overlaying weldability with a kind of automatic heap of mold
Weldering gas slag Combined Protection metal powder core solder wire.
The present invention is achieved in the following ways a kind of mold automatic surfacing gas slag Combined Protection metal powder core solder wire,
Be made of steel band package powder core, the powder core include micro- slag ingredient A and alloy element component B, micro- slag ingredient A according to
Weight percent includes：Rutile 4%, fluorite 1.3%, ice crystal 0.3%, potassium titanate 1.1%, quartz 1%；
The alloy element component B includes according to weight percent：45# ferrosilicon 4.8%, manganese metal 9.5%, metallic nickel 6.5%,
Crome metal 3.5%, micro ferrochrome 1.5%, molybdenum-iron 6.35%, vanadium iron 0.25%, Al-Mg alloy powder 3.5%, surplus are iron powder.
The steel band is flux-cored wire special steel strip, and the steel band ingredient is according to mass percent：C：
0.028%, Mn：0.23%, Si≤0.0394%, S ＜ 0.0004%, P ＜ 0.006%, surplus be iron and impurity, wherein Si,
S, the content of P is not 0.
The powder core filling rate is 26%-27%.
Beneficial effects of the present invention are that welding wire uses gas slag duplicate protection, and postwelding, which forms deposited metal surface, micro melt
In deposited metal surface multi-layer welding may be implemented, and spatter is seldom in slag, thin and uniform fold, arc stability, downhand welding
When deposited metal do not trickle, forming is beautiful, has excellent welding technological properties and comprehensive mechanical property.
Specific implementation mode
A kind of mold automatic surfacing gas slag Combined Protection metal powder core solder wire is made of steel band package powder core, described
Powder core includes micro- slag ingredient A and alloy element component B, micro- slag ingredient A include according to weight percent：Rutile 4%,
Fluorite 1.3%, ice crystal 0.3%, potassium titanate 1.1%, quartz 1%；
The alloy element component B includes according to weight percent：45# ferrosilicon 4.8%, manganese metal 9.5%, metallic nickel 6.5%,
Crome metal 3.5%, micro ferrochrome 1.5%, molybdenum-iron 6.35%, vanadium iron 0.25%, Al-Mg alloy powder 3.5%, surplus are iron powder.
The steel band is flux-cored wire special steel strip, and the steel band ingredient is according to mass percent：C：
0.028%, Mn：0.23%, Si≤0.0394%, S ＜ 0.0004%, P ＜ 0.006%, surplus be iron and impurity, wherein Si,
S, the content of P is not 0.
The powder core filling rate is 26%-27%.
So micro- slag gas shielded flux cored wire that the welding wire is 2% quantity of slag is not easy slag inclusion because the quantity of slag is few, weldering is realized
3~4 layers of scarfing cinder are primary in termination process, improve welding efficiency, because there is the Combined Protection of slag gas, avoid the generation of stomata,
It ensure that welding quality.
