Abstract
The present invention relates to a welding material-flux-cored wire special for repairing continuous cast roll. It is characterized by that the powdered ferroalloy, dust iron and dust chrome including ferromanganese, ferrosilicium, ferromolybdenum, ferrochrome, ferrovanadium and ferronickel, are proportioned, uniformly mixed and put on the protected steel band of tubular wire to made the invented tubular flux-cored wire, and its chemical components must be controlled in the following ranges: C 0.04-0.15%, Si 0.2-1.0%, Mn 0.2-2.2%, P is less than or equal to 0.03%, S is less than or equal to 0.03%, Cr 0.5-15%, Mi 0.5-7%, Mo 0.4-1.5%, V 0.15-0.3%, W 0.25-0.5%, Nb 0.05-0.15% and the rest is Fe. It's cost can be reduced by 30%, crack resistance can be raised 2-3 times as compared with solid wire, and the service life of the continuous cast roll can be greatly prolonged.
Description
Patent of the present invention relates to a kind of welding material-special flux-cored wirecord for repairing continuous-casting roller.
At present, HCr13 series resurfacing welding material is mainly adopted in domestic reparation to heavy slab continuous casting roller, have that working lining cold-and-heat resistent fatigability is poor, serious cracking, wear no resistance, problem such as service life is low.
The objective of the invention is provides a kind of novel resurfacing welding material-special flux-cored wirecord for repairing continuous-casting roller for repairing the continuous casting roller, is to adopt multi-component alloying, improves the cold-and-heat resistent fatigue behaviour and the anti-wear performance of deposited metal.
Special flux-cored wirecord for repairing continuous-casting roller content Description of the present invention:
Special flux-cored wirecord for repairing continuous-casting roller of the present invention, it is characterized in that: the chemical analysis that requires determined deposited metal according to continuous casting roller serviceability, choose: ferromanganese, ferrosilicon, molybdenum-iron, ferrochrome, vanadium iron, ferroalloy powdeies such as ferronickel, iron powder and hafnium metal powfer, its granularity is the 80-100 order, pack into after requiring in proportion evenly to mix and manage in the distributing device of silk wire rolling mill, when wire rolling mill is worked that mixed uniformly powder is stable and be sprinkling upon equably and wrap up into tubulose on the pipe silk foreskin steel band, carry out drawing through wire drawing machine again, making external diameter is the tubulose flux-cored wire of φ 3.2-4.0mm; The chemical analysis of tubulose flux-cored wire should be controlled at: C0.04-0.15%, Si0.2-1.0%, Mn0.2-2.2%, P≤0.03%, S≤0.03%, Cr0.5-15%, Ni0.5-7%, Mo0.4-1.5%, V0.15-0.3%, W0.25-0.5%, Nb0.05-0.15%, surplus are Fe.
