Abstract
The utility model relates to a roller, in particular to a high-hardness alloy cladding roller with a cladding layer on the surface. The high-hardness alloy cladding roller comprises a roller shaft and a roller body, the outer surface of the roller body is provided with the cladding layer, and high-hardness alloy powder is inlaid in the cladding layer. The surface of the roller is treated by the aid of the surface cladding technology, so that enormous waste of the roller caused by diameter reduction and scrapping is avoided, materials of sand blasting (or sand pressing) processes and energy consumption are saved, and production cost and social resources are economized.
Description
Technical field
The utility model relates to a kind of roll, relates in particular to the high hardness alloy cladding roll that a kind of surface is provided with cladding layer.
Background technology
The roll body of existing roll mostly is two kinds of the centrifugal or formwork erection casting of monometallic and bimetal centrifugal castings.Repeat to process the roll that the roll that uses repeatedly mostly is bimetal centrifugal casting.This roll roll body internal layer is a plain cast iron, and outer about 20mm is thick to be alloy cast iron (spoken parts in traditional operas) layer, to increase outer hardness and wearability.According to different instructions for uses, the roller surface form processing mainly contains two kinds: a kind of is to utilize wire drawing machine that roller surface is processed into profile of tooth; Another kind is a mode of utilizing sandblast (or pressing sand), and roller surface is processed into matsurface.Roll is serious wear in use, generally use for 2~April after, because of can not satisfy technological requirement repeat processing.Every processing once, roller diameter reduction 0.5~6mm is that the roll of Φ 250mm is an example with the diameter, as diameter reduction 15~20mm, just scraps because of not satisfying the equipment instructions for use.Roll is scrapped because of diameter reduction, has not only increased the acquisition cost of roll, more causes the huge waste of material, the energy and resource.
Summary of the invention
For addressing the above problem, the roll that the utility model provides a kind of surface to have the high hardness alloy cladding layer, roll can be handled through cladding and recycle, and has fully improved the utilization rate of roll.
High hardness alloy cladding roll described in the utility model comprises roll shaft and roll body, and described roll body outer surface is provided with cladding layer, and cladding layer is embedded with the high hardness alloy powder.The utility model utilizes the surface cladding technology to make alloy powder and roll body surface fuse, recover diameter after not only making roll wear, can also according to instructions for use adjust surface fused coating composition, ratio, thickness, surface roughness and use from degree of roughness, the wearing and tearing roll is being repeated to add man-hour, not needing by sandblast (or pressing sand) roughening to be carried out on the surface again handles, thereby the energy and resource have been saved, reduced production cost, improve operating efficiency, improved working environment greatly.
Further, described high hardness alloy powder is mixed by in nickel, chromium, boron, silicon, vanadium, titanium, tungsten, the molybdenum one or more.Composition, ratio and the granularity of alloy powder can specifically be set, to meet technological requirement during preparation according to the instructions for use of roll.
Preferably, described roll body comprises roll body inner core and the roll body urceolus that removably connects with it, and the roll body inner core adopts the plain cast iron manufacturing, and the roll body urceolus adopts the alloy cast iron manufacturing.During roll body urceolus serious wear, can only change the roll body urceolus, the roll body inner core can reuse, and roll body only part adopt the high alloy cast iron of price, the wearability that neither hinders roll body has been saved manufacturing cost again.
Certainly, also can use traditional roll, promptly described roll body is formed by monometallic centrifugal casting, and perhaps described roll body is formed by bimetal centrifugal casting, and skin is an alloy cast iron, and internal layer is a plain cast iron.The latter is equally in order to save manufacturing cost.
The utility model adopts surface cladding technology breaker roll surface to handle, and has both avoided roll to scrap the huge waste that causes because of diameter reduction, has saved the material and the energy resource consumption of sandblast (or pressing sand) operation again, has saved production cost and social resources.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail:
Fig. 1 is the structural representation of the utility model embodiment 1;
Fig. 2 is the structural representation of the utility model embodiment 2;
Among the figure, the 1st, roll shaft, the 2nd, roll body, the 3rd, roll body inner core, the 4th, roll body urceolus, 5, cladding layer, 6, the high hardness alloy powder.
The specific embodiment
Embodiment 1
A kind of high hardness alloy cladding roll, as shown in Figure 1, comprise roll body 2, described roll body 2 is formed by roll body inner core 3 and roll body urceolus 4 suits, and both removably connect, and roll body inner core 3 adopts plain cast iron to make, roll body urceolus 4 adopts alloy cast iron to make, fixedly connected two roll shafts 1 in roll body inner core 3 two ends, described roll body urceolus 4 outer surfaces are provided with a cladding layer 5, and this cladding layer 5 is to be formed by high hardness alloy powder 6 and 4 claddings of roll body urceolus.Described high hardness alloy powder 6 is mixed by nickel chromium triangle borosilicate alloy powder and tungsten-carbide powder.
A kind of high hardness alloy cladding roll as shown in Figure 2, comprises the roll body 2 by the alloy cast iron casting, fixedly connected two roll shafts 1 in roll body 2 two ends, and described roll body 2 outer surfaces are provided with a cladding layer 5, and this cladding layer 5 is to be formed by high hardness alloy powder 6 and roll body 2 claddings.Described high hardness alloy powder 6 is mixed by nickel chromium triangle borosilicate alloy powder and tungsten-carbide powder.
