Description
Technical field
The present invention relates to a kind of high ferro-boron base abrasion-proof overlaying welding flux-cored wire, belong to field of welding material.Can be widely used on the mechanical wearing piece of industries such as electric power, coal, metallurgical mine, chemical industry, machinery, be used for built-up welding and repair wearing piece, such as coal pulverizer grinding roller, turbine blade, excavator bucket teeth, extruder auger, reamer etc.
Background technology
The flux-cored wire of built-up welding reparation at present generally all is a rich chromium cast iron series, promptly contain alloying elements such as carbon, chromium, silicon, manganese, with certain strong carbide forming element, as tungsten, molybdenum, niobium, vanadium etc., its wearability mainly is that the NbC, the WC that form of the double carbide M7C3 that forms in carbon and iron in overlay cladding by chromium and strong carbide forming element, VC etc. form good binding as wear-resisting skeleton and matrix and play wear-resistant shock resistance effect, uses comparatively to have goed deep into and ripe.But, in recent years, chromium, aluminium, nickel, tungsten etc. are becoming tight alloy supply day, and price skyrockets, and causes common iron and steel antifriction alloy, production cost constantly rises and has limited further applying of rich chromium cast iron, boron is that China is rich in element, and in hardfacing alloy, the hardness of boride and heat endurance all are higher than carbide, particularly FeB (HV1900), the Fe2B (HV1585) of the generation of boron and iron are formed into titanium boride TiB with titanium
2(HV3400) microhardness is all higher, so boron is that surfacing welding alloy has application promise in clinical practice.
Some is fit to low alloy that impact, the abrasive wear industrial and mineral, and to contain noble metal such as tungsten, niobium, vanadium etc. a lot, and cost is higher.For example the Chinese patent wear-resistant overlay welding alloy material relates to a kind of wear-resistant overlay welding alloy material, and its alloy is specifically formed content and is: W 5～30%, Nb 2～15%, V 3～12%, Mo 1～8%, Cr 1～5%, B2～7%, rare earth 0.01～2%, surplus are Fe.This invents not carbon elements, is the hard hardening constituent with the heavy metal boride, and boride plays wear-resisting skeleton function in alloy, alloy substrate is produced protective effect mutually, and microhardness is all between HV1700～2800.This invention wearability is better but because noble metal is a lot, so cost is higher, patent publication No. is characterized in that for CN 1086471A relates to a kind of boron carbide wearproof weld rod for building-up welding: add heavy dose of boron carbide and a certain amount of chromium, nickel, molybdenum, titanium and a spot of tungsten, vanadium, niobium, rare earth alloy element in the coating, noble metal tungsten, vanadium, nickel, molybdenum cause its cost higher, and the higher hardfacing alloy fragility of carbon content is big.021,394,938 1 kinds of built-up welding welding wires of Chinese patent for example again, its drug core component is Cr 25～30%, Ni 15～19%; Mn3～5; Si 2～5%; B 3.5～6%; C 1～3%, the Fe surplus.This invention wearability is good but shortcoming is a fragility peels off greatly easily, and metal such as nickel chromium triangle is more, and cost is higher.
Summary of the invention
The present invention is a kind of high ferro-boron base abrasion-proof overlaying welding flux-cored wire; its wearability mainly is Fe2B, the FeB that forms with iron in overlay cladding by the boron in the ferro-boron; form titanium boride with titanium; its microhardness is all higher; as wear-resisting skeleton alloy substrate is produced protective effect in antifriction alloy, the present invention is by mild steel foreskin and core powder constituent.
The technical scheme of taking for achieving the above object is: a kind of high ferro-boron base abrasion-proof overlaying welding flux-cored wire, welding wire is by mild steel foreskin and core powder constituent, it is characterized in that ferro element and core powder in the mild steel foreskin, element in the core powder comprises boron, carbon, manganese, element silicon, boron in the core powder, carbon, manganese, the shared welding wire percentage by weight of element silicon are: boron 6～12%, carbon 0.1～3%, manganese 0.6～2%, silicon 0.3～1.5%, surplus are iron.
Also comprise titanium elements in the above-mentioned described core powder, wherein titanium elements accounts for 0.3～3.5% of flux-cored wire quality.
Can also add one or more of following alloying element in the core powder of above-mentioned abrasion-proof overlaying welding flux-cored wire, the weight of its shared welding wire is: molybdenum (Mo) 0～1%, nickel (Ni) 0～1%, rare earth (RE) 0～1%, almag 0～1.5%, Na/K alterant 0～1%.
Rare earth (RE) is wherein a kind of of cerium (Ce), lanthanum (La) neodymium (Nd), or their mixture.
The main component effect is as follows in the medicine core:
Introduce boron element, boron carbide is or/and ferro-boron: wherein the hardness and the wearability of ferro-boron introducing boron element overlay cladding increase along with the increase of boron content; Boron carbide is introduced boron element, the hardness of overlay cladding and wearability increase along with the increase of boron content, mainly act as the introducing carbon, along with the carbide containing boron volume fraction in the increase eutectic structure of carbon content increases accordingly, while hardness is improved but carbon content is crossed high tenacity decline under the certain condition of boron content.
Ferromanganese: Mn has good deoxidation and desulfidation, and has stronger solution strengthening effect; Can improve hardenability.
The deoxidation of 45# ferrosilicon: Si energy, and have strong solution strengthening effect, increase hardenability and temper resistance, improve hear resistance and corrosion resistance, and can reduce the liquid metal surface tension.
Ferrotianium: in the time of good deoxidation, form titanium boride (TiB with boron
2) hard further improves the abrasion resistance properties of hardfacing alloy mutually.
The high ferro-boron base of the present invention abrasion-proof overlaying welding flux-cored wire can add almag, ferro-niobium, can also add the performance that a spot of molybdenum, nickel further improve hardfacing alloy.
The present invention is relative, and the prior art advantage is as follows:
High boron wear-resisting flux-cored wire of the present invention mainly relies on the carbide of formation such as boron, carbon, titanium, iron and the abrasion resistance properties that boride is realized alloy.Elements such as boron, carbon, titanium, manganese, silicon, niobium, molybdenum, nickel reasonably make up in the alloying element by regulating, thereby regulate hardness, the raising toughness of overlay cladding and reduce crack sensitivity, the present invention adds the niobium element and potassium sodium alterant can reduce boride size raising toughness, adds rare earth element and purifies the combination property that the crystal boundary crystal grain thinning further improves hardfacing alloy.And the valuable alloying element that adds is less, adds boron and has substituted precious metal element, and is with low cost.
Its main abrasion mechanism is: because a large amount of boron element that adds in the flux-cored wire and an amount of carbon, titanium; and then in overlay cladding, formed a large amount of boron carbon compound hard and reached titanium boride mutually; its microhardness is all higher; the hard of opposing wearing and tearing cutting increases mutually; wear-resisting skeleton function has been played in the be on good terms cutting of opposing abrasive material of hard, simultaneously matrix is played a very good protection, and makes abrasive material cutting be difficult to carry out; reduced weight loss, wearability is improved.
Welding wire of the present invention is realized by the following method:
1, steel band is rolled into U-shaped, and adding prepares in advance and arrives predetermined filling rate (28～50%) through well-mixed alloy powder (selected powder size is more than 80 orders) in U-lag
2, U-lag is healed up roll into o shape, make medicine core parcel wherein,,, make its diameter reach 1.6～3.2mm at last, obtain final products by road drawing, tube reducing by wire drawing die.
