Abstract
The invention relates to a mould surfacing welding electrode. The coating is prepared from silver flake graphite, marble, fluorite, titanium dioxide, quartz, ferromolybdenum, ferrovanadium, ferroboron, tungsten carbide, medium carbon ferromanganese, rare earth silicon and aluminum powder. The core wire is 1Cr13 stainless steel. The binder is sodium water glass. The production is carried out by adopting a common oil press. The ceramic mould can be manufactured by using 45 # steel and the like as a matrix to build up the periphery of the matrix, the worn mould can be repaired, the matrix can be repeatedly used, and the build-up metal has higher hardness and wear resistance. The welding rod is mainly used for surfacing manufacture and repair of ceramic molds, and can also be popularized to manufacture and repair of other molds.
Description
A kind of mould surfacing welding is used for the mould built-up welding and makes and repair, and particularly the ceramic die built-up welding is made and repaired.
Ceramic die belongs to vulnerable part, adopts Cr12MoV mould steel to make this mould, the manufacturing cost height.The ceramic die wear out failure only is four peripheries.Adopt common 45# steel to do die body, on die body, use four working edges of method built-up welding of padding again, can reduce die manufacturing cost greatly, can reach instructions for use again.The ceramic die that uses in producing now have still by import, promptly consume a large amount of foreign exchanges and can not in time supply again.The employing inlet gas welding wire built-up welding that has, cost is too high, and (1000 yuan of welding wire valencys/more than the kg, only 20-30 unit/Kg), built-up welding speed is slow for welding rod cost of the present invention, and it is unreliable that deposited metal combines with mother metal.It is very poor that the employing that has has common wear resistance electrode built-up welding (mould of producing as Guangzhou factory substitutes welding rod) wearability now, and deposited metal is not corrosion-resistant again, can not satisfy production requirement.Invention disclosed patent application CN 88 1 05652 A have narrated the wear-resisting not preheating surfacing of a kind of ultrahigh hardness welding rod, the bonding agent of its electrode coating is a sodium silicate, comprise marble, fluorite, titanium dioxide, graphite, high carbon ferro-chrome, mid-carbon fe-mn, molybdenum-iron, vanadium iron, tungsten carbide, particle boron in the electrode coating, core wire adopts the H08A core wire.Must preheating before the weldering of this welding rod, postwelding must heat treatment, and layer hardness height, wearability is better.But what this welding rod adopted is common H08A core wire, and chrome content is low in the deposited metal, does not reach the passivation amount, deposited metal is under wet raw material medium effect, and corrosion is serious, and chromium content is low, differ bigger with the composition of Cr12MoV mould steel, anti-wear performance is also not ideal.
Purpose of the present invention is developed exactly and a kind ofly can be used for ceramic die built-up welding, wear-resisting, the corrosion resistant surfacing welding of deposited metal.
The present invention adopts following technical scheme to realize.Mould is a sodium silicate with the bonding agent of coating of build-up welding bar, and this electrode coating by silver strip graphite,, marble, fluorite, titanium dioxide, molybdenum-iron, vanadium iron, tungsten carbide, mid-carbon fe-mn, quartz, ferro-boron, rare earth silicon, aluminium powder be mixed with.The weight ratio of coating recipe is: silver strip graphite 0.5-3, marble 8-15, fluorite 2-5, titanium dioxide 4-10, quartzy 1-4, molybdenum-iron 15-25, vanadium iron 8-14, ferro-boron 15-25, tungsten carbide 8-15, mid-carbon fe-mn 1-5, rare earth silicon 3-8, aluminium powder 1-3; Core wire adopts Cr13 type stainless steel core wire; Raw material are required: silver strip graphite phosphorus content must be more than 98%, and the vanadium content in the vanadium iron is 50-55%, and silicon content is less than 2%, and the boron content in the ferro-boron is 18-21%, and all the other raw material are checked and accepted with raw material standards by welding rod.
Welding rod advantage of the present invention is: can do matrix built-up welding periphery with ordinary steel such as 45# steel etc. and make ceramic die, can repair worn out mould, matrix can repeated multiple times use: deposited metal has higher hardness and wearability.Its hardness can be adjusted between HRC45-62 according to the disparate modules specific requirement; The mould of making can be suppressed 200,000 blocks more than the ceramic tile, reach and surpass the life-span of Cr12MoV mould: owing to be to do core wire with the stainless steel core of 1Cr13, deposited metal has certain corrosion resistance, the cleaning and the smooth requirement of module have been guaranteed, save non-cutting time and improved the quality of ceramic tile, the deposited metal crack resistance is better, and the deposited metal obdurability is good.
Embodiment one: (unit can use g, Kg etc. to adopt following weight ratio preparation coating, can enlarge or dwindle some multiples simultaneously according to producing welding rod quantity) silver strip graphite 1, marble 15, fluorite 5, titanium dioxide 5, quartzy 3, molybdenum-iron 20, vanadium iron 14, ferro-boron 16, tungsten carbide 15, mid-carbon fe-mn 2, rare earth silicon 3, aluminium powder 1, whole mistake 40 mesh sieves of medicinal powder, electrode size is 3.2mm, the coating external diameter is 5.1mm, sodium silicate concentration is 45-50Be, adopts common 25T extrusion press to get final product suppression electrode.
Embodiment two: silver strip graphite 2, marble 15, fluorite 2, titanium dioxide 7, quartz 2, molybdenum-iron 25, vanadium iron 10, ferro-boron 20, tungsten carbide 8, mid-carbon fe-mn 3, rare earth silicon 5, aluminium powder 1, all the other conditions can suppress welding rod with embodiment one.
With the welding rod that above two embodiment make, built-up welding on the 45# steel, adopting model is the welding machine of ZXG7-300, straight polarity direct current, and welding current is 110A, after the built-up welding, deposited metal hardness height, crack resistance is good, and wear-corrosion resistance is good.
