Abstract
The utility model belongs to the field of accessories of a straightening machine, and discloses an improved straightening roll. The improved straightening roll aims to solve the technical problems that an existing straightening roll is abraded easily, the working efficiency is low, and resources are wasted. According to the technical scheme, the improved straightening roll comprises a roll body, an inner sleeve is arranged inside the roll body and is provided with at least one cast-insert slot, the inner sleeve and the roll body are cast into a whole, a surfacing alloy layer is arranged on the working surface of the roll body, and an oxide ceramic layer is arranged on the outer surface of the surfacing alloy layer. The improved straightening roll has the advantages of being reasonable in structure, long in service life and high in product quality.
Description
Technical field
The utility model relates to a kind of improved smoothing roll, belongs to straightener accessory field.
Background technology
Smoothing roll is one of must obligato process kit during shaped steel, steel pipe and Strip are produced.Smoothing roll in use, because intensity and the hardness of metal to be processed are all larger, cause the surface stress of smoothing roll relatively also larger, after smoothing roll works long hours, its surface just there will be very serious wear phenomenon, after wearing and tearing severity, be just compelled to do and scrap processing, like this waste resource on the one hand, also can affect operating efficiency on the other hand.In addition, the quality of smoothing roll will directly affect the quality of product, therefore how to improve the quality of smoothing roll and just seems service life extremely important and necessary.
Summary of the invention
The purpose of this utility model is: the deficiency of bringing for solving existing smoothing roll, provides a kind of rational in infrastructure, long service life, improved smoothing roll that product quality is high.
For realizing above-mentioned deficiency, the technical solution adopted in the utility model is:
A kind of improved smoothing roll, comprise roll body, the inside of described roll body is provided with inner sleeve, in described, put and be provided with at least 1 embedding casting groove, described inner sleeve and roll body embedding are cast as one, the working surface of described roll body is provided with one deck hardfacing alloy layer, and the outer surface of described hardfacing alloy layer is provided with one deck oxide ceramic layer.
More preferably, the thickness of described oxide ceramic layer is 50-100um.
More preferably, described roll body is formed by the high flatiron casting of low-carbon (LC).
More preferably, described inner sleeve is formed by steel alloy manufacture.
More preferably, the thickness of described oxide ceramic layer is 80um.
Due to employing the utility model of technique scheme compared with prior art tool have the following advantages:
1, because the utility model is provided with one deck hardfacing alloy layer on the working surface of roll body, hardfacing alloy is comprised of the alloy material of high carbon and chromium, and the hardness that it can improve roll body strengthens its resistance to compression wear resistence, extends the service life of roll body, reduces production costs.
2, because the utility model is provided with one deck oxide ceramic layer at the outer surface of hardfacing alloy layer, oxide ceramic layer has advantages of that structure machine is tight, intensity is high, resistance to wears, physicochemical property is stable under hot environment, such structural design has effectively extended the service life of smoothing roll, thereby the production efficiency that has improved enterprise, has reduced production cost.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model embodiment mono-structural representation;
In above accompanying drawing: 1, roll body, 2, inner sleeve, 3, embedding casting groove, 4, hardfacing alloy layer; 5, oxide ceramic layer.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further described:
Embodiment mono-:
Shown in accompanying drawing 1, a kind of improved smoothing roll of the utility model, comprise roll body 1, the inside of roll body 1 is provided with inner sleeve 2, inner sleeve 2 is provided with at least 1 embedding casting groove 3, inner sleeve 2 is cast as one with roll body 1 embedding, and the working surface of roll body 1 is provided with one deck hardfacing alloy layer 4, and the outer surface of hardfacing alloy layer 4 is provided with one deck oxide ceramic layer 5.
As a kind of preferred, roll body 1 is formed by the high flatiron casting of low-carbon (LC).
As a kind of preferred, inner sleeve 2 is formed by steel alloy manufacture.
As a kind of preferred, the thickness of oxide ceramic layer 5 is 50-100um.
More excellent, the thickness of oxide ceramic layer 5 is 80um.
A kind of improved smoothing roll of the utility model is provided with one deck hardfacing alloy layer 4 on the working surface of roll body 1, and hardfacing alloy layer 4 is comprised of the alloy material of high carbon and chromium, it can improve the hardness of roll body 1, strengthen its resistance to compression wear resistence, extend the service life of roll body 1, reduce production costs.In addition, outer surface at hardfacing alloy layer 4 is provided with one deck oxide ceramic layer 5, oxide ceramic layer 5 has advantages of that structure machine is tight, intensity is high, resistance to wears, physicochemical property is stable under hot environment, such structural design has effectively extended the service life of smoothing roll, thereby the production efficiency that has improved enterprise, has reduced production cost.
Above-described embodiment is only explanation technical conceive of the present utility model and feature, and its object is to allow person skilled in the art can understand content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, within all should being encompassed in protection domain of the present utility model.
