Description
One, technical field
The present invention relates to a kind of welding rod that is used to weld, particularly a kind of electric welding core with forging rolling system high mangaenese steel silk.
Two, background technology
The high mangaenese steel welding property is bad, but the premium properties of its high strength, high tenacity, high wear-resistant, no magnetic, make a lot of occasions all use it.But because high mangaenese steel work hardening is fast, difficult cutting is generally limited to do foundry goods and uses.Though use to some extent in welding at present, because material component is unreasonable, effect is very undesirable.The material that the high mangaenese steel welding is used at present such as following each table:

See by above data, heap 256, heap 266 is common high-quality electric welding core owing to core wire, the content of its manganese
Can only be dissolved in when welding by welding agent, fast during owing to welding, the welding of ferromanganese content is inhomogeneous, weldability
Can be bad, limited its use range.
Three, summary of the invention
At above-mentioned situation, the present invention's purpose just is to provide a kind of electric welding core with forging rolling system high mangaenese steel silk, as manual welding electrode core, submerged arc welding rod and other high mangaenese steel core wire, it is inhomogeneous to solve the ferromanganese welding effectively, the bad problem of the not high welding property of weldquality, the technical scheme of its solution is to adopt chemical composition to count with massfraction: 1-1.3%C, 0.3-0.5%Si, 11-14%Mn, P≤0.035%, S≤0.025%, surplus is that the high mangaenese steel silk of Fe is made the electric welding core, this electric welding core welding welding is even, the firm quality of weld seam is good, intensity is big, the toughness height, high wear-resistant, purposes is wide, both can be used as manual welding electrode core, submerged arc welding rod or other high mangaenese steel core wire, it is applied is the big creative contribution that high mangaenese steel is welded.
Four, embodiment
Below in conjunction with practical situation the specific embodiment of the present invention is elaborated.
Electric welding core of the present invention is to make the electric welding core with the high mangaenese steel silk that forging rolling is made to make, high mangaenese steel wire chemical component is counted C (carbon) content 1-1.3%, Si (silicon) content 0.3-0.5%, Mn (manganese) content 11-14%, P (phosphorus) content≤0.035%, S (sulphur) content≤0.025% with massfraction, surplus is Fe (iron), the realization of this material is to adopt smelting, forging, rolling, thermal treatment to make to forge rod to carry out wire drawing again to form, after the wire drawing routinely processing boring with the electric welding core of forging rolling system high mangaenese steel.Or adopt other to smelt making method and make material of the present invention and make the electric welding core again and also can; its making method is not limit; also have no special requirements; so long as by chemical composition in total mass number: 1-1.3%C, 0.3-0.5%Si, 11-14%Mn, P≤0.035%, S≤0.025%, surplus is that the electric welding core that the high mangaenese steel silk of Fe is made is the scope of protection of the invention.
As everybody knows, high mangaenese steel in the world, the applicating history in existing more than 180 year, still, because the high mangaenese steel welding property is bad, therefore be not utilized effectively as welding always, and the high mangaenese steel that uses at present mostly is soft steel, show by preceding table, and its content≤below 0.9%, and carbon content of the present invention is at 1-1.3%, because high carbon content and its component content is different, makes the present invention have special significance, has constituted a kind of high mangaenese steel (D.110Mn13) of new variety fully, after tested, high mangaenese steel silk with this composition is done core wire, and its ferromanganese content dissolving is even, and weldquality is good, intensity is big, performance is good, and purposes is wide, and has overcome the problem that the content of common its manganese of high-quality electric welding core can only the time be dissolved in welding by welding agent, the present invention has opened up the bright prospect that the electric welding core is used, and has huge technique effect and economic benefit.
