Description
Technical field
The invention belongs to surface reconditioning field of engineering technology, particularly to a kind of build-up welding of continuous casting roller welding wire.Especially
Relate to a kind of low cost build-up welding of continuous casting roller welding wire.
Background technology
Continuous Casting Rolls is the Critical Spare Part of steel-making continuous casting complete set of equipments, and its performance quality is directly connected to the use of equipment
In the life-span, have influence on the operating rate of equipment, the production cost of continuous casting billet and product quality.For a long time, metallurgical enterprise
Industry updates the resurfacing welding material of Continuous Casting Rolls, and the service life of Continuous Casting Rolls improves constantly.Owing to Continuous Casting Rolls makes recruitment
Make bad environments, be subjected to the thermal stress of the alternation of the high temperature of steel billet and the low temperature of cooling water, but also hold
Acted on by mechanical stresses such as slab bulge power and static pressures, additionally, also subject to stagnant base and bleed-out etc. water steel abnormal,
Lubrication and cool down the unit exception such as bad, change non-equilibrium heat that tundish and slide gate nozzle etc. cause and non-equilibrium
The effect of stress, working condition is the harshest.The failure mode that Continuous Casting Rolls occurs after using has: roll body bending,
Surface abrasion, surface checking, surface corrosion, surface peeling etc..
Current domestic main use two categories below welding wire carries out the Bead weld repair of Continuous Casting Rolls, the alloy of this two classes welding wire
System is:
0.05%C-1.0%Mn-14%Cr-4%Ni-0.6%Mo and
0.12%C-1.0%Mn-14%Cr-2.5%Ni-0.7%Mo.
The Continuous Casting Rolls of this two classes welding wire built-up welding reparation has preferable service life, the steel transportation amount of unit single current casting machine
70-100 ten thousand tons, but the production cost of this two classes welding wire is higher.For reducing the production cost of welding wire, research
Develop the build-up welding of continuous casting roller welding wire of a kind of low cost.Welding wire has relatively low production cost, and welding wire built-up welding is repaiied
Multiple Continuous Casting Rolls has higher service life, and the Continuous Casting Rolls roll surface hardness of Bead weld repair is HRC41-44, mistake
Steel amount is more than 900,000 tons.
Summary of the invention
It is an object of the invention to provide a kind of build-up welding of continuous casting roller welding wire, solve current welding wire high expensive,
The problem that life-span is low.
Solve the basic ideas of technical problem: carry out component of weld wire optimization, add lot of trace alloying element, with
Improve the hardness of deposited metal, improve overlay cladding anti-wear performance, reduce the phosphorus content of deposited metal, to improve heap
The anti-fatigue performance of weldering metal.
A kind of build-up welding of continuous casting roller welding wire, composition range is by mass percentage: C:0.03-0.09%, Mn:
1.80-3.50%, Cr:12.5-16.5%, V:0.07-0.25%, Nb:0.05-0.20%, Cu:0.50-1.80%,
Remaining is Fe.
Use sintered flux or fysed flux that the present invention provides the welding wire coupling trade mark to be 107, the company of Bead weld repair
The hardness of casting roll is HRC40-45, and the Continuous Casting Rolls of Bead weld repair has higher service life, and its steel transportation amount exists
More than 900000 tons, its service life and the most commonly used
The phase in service life of the Continuous Casting Rolls that 0.05%C-1.0%Mn-14%Cr-4%Ni-0.6%Mo alloy system welding wire is repaired
When, it is better than 0.12%C-1.0%Mn-14%Cr-2.5%Ni-0.7%Mo the service life of the Continuous Casting Rolls of reparation and closes
The Continuous Casting Rolls that gold series solder wire is repaired, and the manufacturing cost of welding wire is substantially less than the most commonly used both welderings
Silk.
It is to select relatively low phosphorus content, to improve heap during component of weld wire design that the present invention solves the key problem in technology of problem
The thermal fatigue resistance of layer, selects lot of trace alloying element, to improve the hardness of deposited metal, improves heap
Layer anti-wear performance.The carbon content scope of the welding wire that the present invention provides is 0.03-0.09%, and carbon content is less than
0.03%, surfacing hardness is on the low side, causes the Continuous Casting Rolls of Bead weld repair to wear no resistance, and reduces the use of Continuous Casting Rolls
In the life-span, carbon content is higher than 0.09%, and the thermal fatigue resistance of the Continuous Casting Rolls of Bead weld repair degenerates, and also reduces Continuous Casting Rolls
Service life.V, Nb are carbide, these alloying elements and built-up welding in welding process
In Ceng, C-shaped becomes carbide, disperse educt in welding cooling procedure, and crystal grain thinning improves surfacing hardness.
V OK range be 0.07-0.25%, Nb OK range be 0.05-0.20%, V, Nb alloying element content
Too low, then DeGrain, too high, cause the removability of slag of welding wire to degenerate.Cr content improves overlay cladding and resists
Corrosive nature, Cr content is less than 12.5%, and the Continuous Casting Rolls corrosion resistance of reparation is deteriorated, and service life is relatively low,
Cr content is higher than 16.5%, then overlay cladding ferrite content is higher, and surfacing hardness is on the low side, the Continuous Casting Rolls of reparation
Service life is relatively low, and Cr content OK range is 12.5-16.0%.Mn in the component of weld wire that the present invention provides
Effect with Cu is the hardness improving overlay cladding, and the OK range of Mn content is that Mn1.80-3.50%, Mn contain
Amount is less than 1.80%, and surfacing hardness is on the low side, reduces the service life of the Continuous Casting Rolls of Bead weld repair, and Mn content is high
In 3.50%, also can reduce the hardness of overlay cladding, also reduce the service life of Continuous Casting Rolls.The suitable model of Cu content
Enclosing for Mn0.50-1.80%, Cu content less than 0.50%, surfacing hardness is on the low side, and content is higher than 1.80%, also
The hardness of overlay cladding can be reduced, also reduce the service life of Continuous Casting Rolls.
It is an advantage of the current invention that: component of weld wire phosphorus content is relatively low, overlay cladding has good thermal fatigue resistance,
Adding lot of trace alloying element in welding wire, deposited metal has higher hardness, and overlay cladding anti-wear performance is good,
In the composition design of welding wire, valuable rare element content is low, the low cost of manufacture of welding wire.
