Abstract
The utility model relates to the field of the building device, and discloses a roller for a continuous caster; a cladding is of a tungsten carbide flux-cored chrome stainless steel layer and is overlaying welded on the surface of a roller body; the thickness of the tungsten carbide flux-cored chrome stainless steel layer is more than 3 mm and is equal to or less than 10 mm. The hard cladding of the roller for the continuous caster is rigid and can better resist the corrosion, abrasion, impact and flame cutting; moreover, by adopting the above material, the roller surface is free from being adhered to the casting billet; the service life is more than 18 months, and the economic benefit is very remarkable.
Description
Technical field
The utility model relates to the Architectural Equipment field, relates in particular to a kind of conticaster roller.
Background technology
Strand is being carried out in drawing, alignment and the course of conveying, and mechanical load is big especially, causes the strand translational speed very slow.In carrying the strand process, because of cutting machine does not cut off strand fully, and need people manually to cut off with flame cutter, if dynamics grasp at this moment is bad, often makes flame cutter that conveying roller is cut perforation, thereby roller is scrapped, cause waste.
Normal spraying or the spray welding process of adopting is provided with a spraying or a spray-welding coating on the roller surface at present, but the adhesion of spraying or spray-welding coating and roll body is not strong, easily comes off.
In use, roll surface contacts with strand for a long time, and roll surface temperature rises fast, the temperature height, and often repeatedly through cool water shower, this colds and heat succeed each other and causes roll surface to chap.
Roll surface is subjected to the corrosion of high-temperature oxydation and cooling water, causes the body of roll impaired, causes mechanical strength to reduce greatly, and service life is short, generally has only about 3 months.
The spraying or the spray-welding coating on roll surface surface very easily peel off, and roll surface is uneven, has a strong impact on cc billet surface quality.
To sum up, there is following shortcoming in present conticaster with roller:
1, poor performance, roll surface are easily cut perforation, and steel bonding phenomenon especially severe.
2, the bearing length time of roller is subjected to temperatures involved, produces oxidation and distortion, and association is not steady changeing behind dry slag, long-time vibrations caused burst apart, the phenomenon of locking.
3, service life is short.
The utility model content
The utility model embodiment provides a kind of conticaster roller, and its performance is better.
The conticaster roller that the utility model embodiment provides comprises: roll body,
Built-up welding has tungsten carbide medicine core chrome stainless steel layer on the surface of roll body, thickness＞3 of described tungsten carbide medicine core chrome stainless steel layer millimeter≤10 millimeters.
Alternatively, the material that described roll body adopted is: No. 45 steel.
By on see, use the technical scheme of the utility model embodiment, the tungsten carbide medicine core chrome stainless steel layer of hard is arranged with the surface overlaying of the roll body of roller at this conticaster.Conticaster roller with respect to band spraying or spray-welding coating in the prior art, this conticaster also is provided with the tungsten carbide medicine core chrome stainless steel layer of hard with the surface of roller, advantages such as surperficial hard, more corrosion-resistant, wear-resistant, the shock resistance of roller, anti-flame cutting, and adopt this material, the roll surface strand that can not bond, service life can be more than 18 months, and economic benefit is very remarkable.
And; the thickness of tungsten carbide medicine core chrome stainless steel layer is less than or equal to 10 millimeters greater than 3 millimeters; evidence; adopt this thickness; both with the THICKNESS CONTROL of tungsten carbide medicine core chrome stainless steel layer a suitable scope; can effectively protect the roll body of its covering, again can be with cost control a suitable scope.
Description of drawings
Accompanying drawing described herein is used to provide further understanding of the present utility model, constitutes the application's a part, does not constitute to improper qualification of the present utility model, in the accompanying drawings:
The conticaster of the band tungsten carbide medicine core chrome stainless steel layer that Fig. 1 provides for the utility model embodiment 1 is with the cross-sectional view of roller.
The specific embodiment
Describe the utility model in detail below in conjunction with accompanying drawing and specific embodiment, be used for explaining the utility model in this illustrative examples of the present utility model and explanation, but not as to qualification of the present utility model.
Embodiment 1:
Referring to Fig. 1, this conticaster comprises with roller: roll body 101, wherein, roll body 101 can adopt No. 45 steel or other alloys to constitute.
Built-up welding has tungsten carbide medicine core chrome stainless steel layer 102 on the surface of roll body 101, and wherein, the thickness of this tungsten carbide medicine core chrome stainless steel layer 102 is less than or equal to 10 millimeters greater than 3 millimeters.
This tungsten carbide medicine core chrome stainless steel layer can but be not limited to by following proportion raw material and form:
Carbon: 0.1-0.2%, chromium: 14-16%, silicon: 0.3-0.6%, manganese: 2-3%, molybdenum: 1-2%, nickel: 4-6%, nitrogen: 0.1-0.3%, iron: surplus.
Evidence adopts the tungsten carbide medicine core chrome stainless steel layer of this proportioning raw material to have splendid hardness and anticorrosive degree.
By on see, use the technical scheme of the utility model embodiment, the tungsten carbide medicine core chrome stainless steel layer of hard is arranged with the surface overlaying of the roll body of roller at this conticaster.Conticaster roller with respect to band spraying or spray-welding coating in the prior art, this conticaster also is provided with the tungsten carbide medicine core chrome stainless steel layer of hard with the surface of roller, advantages such as surperficial hard, more corrosion-resistant, wear-resistant, the shock resistance of roller, anti-flame cutting, and adopt this material, the roll surface strand that can not bond, service life can be more than 18 months, and economic benefit is very remarkable.
And; the thickness of tungsten carbide medicine core chrome stainless steel layer is less than or equal to 10 millimeters greater than 3 millimeters; evidence; adopt this thickness; both with the THICKNESS CONTROL of tungsten carbide medicine core chrome stainless steel layer a suitable scope; can effectively protect the roll body of its covering, again can be with cost control a suitable scope.
More than technical scheme that the utility model embodiment is provided be described in detail, used specific case herein principle and the embodiment of the utility model embodiment are set forth, the explanation of above embodiment only is applicable to the principle that helps to understand the utility model embodiment; Simultaneously, for one of ordinary skill in the art, according to the utility model embodiment, the part that on the specific embodiment and range of application, all can change, in sum, this description should not be construed as restriction of the present utility model.
