Abstract
The invention discloses a kind of high hardness type steel roll, including roll mandrel (1), roll body (2), main basic unit (3), wearing layer (4), stiffening layer (5), it is characterised in that：Roll mandrel (1) is connected with the roll body (2), roll body (2) outer layer is connected with main basic unit (3), wearing layer (4) and stiffening layer (5) in turn, and the main basic unit (3) is combined one with wearing layer (4), stiffening layer (5).The high hardness type steel roll of the present invention can be effectively increased shaped roll hardness, so as to enhance the service life of roll by setting main basic unit, wearing layer and stiffening layer in roll body.
Description
Technical field
The present invention relates to a kind of roll, more particularly to a kind of high hardness type steel roll.
Background technology
Roll is the important tool of Rolling production, reduces the effective cost efficiency of roller power consumption, improves operating rate of rolling mill, improve
Rolled piece product quality, reduce the work hardness of worker.Heavy steel rolling mill steel section shop roll mainly includes at present：Universal mill rolls
Roller and smoothing roll etc., wherein universal mill roll include horizontal roller and edger roll, are one of vital parts on milling train, mounted in milling train
Among memorial archway window.Hot-rolled steel section production in, the consumption of roll is very big, especially horizontal roller, it all the time with red heat steel billet
Directly contact.Under normal circumstances, the failure mode of roll mainly has roll wear, roll crack, spalling of rolls and fracture of roller
Deng wherein roll wear, roll crack, spalling of rolls are the main failure forms of shaped roll.
Traditional roll also has the defects of hardness is low, and manufacturing cost is high, and manufacturing process is complicated, and service life is short.
The content of the invention
The technical problems to be solved by the invention be to provide it is a kind of by set in roll body main basic unit, wearing layer with
Stiffening layer, shaped roll hardness can be effectively increased, so as to enhance the high hardness type steel roll of the service life of roll.
In order to solve the above technical problems, the present invention provides a kind of high hardness type steel roll, including roll mandrel, roll body,
Main basic unit, wearing layer, stiffening layer, it is characterised in that：Be connected with roll mandrel in the roll body, the roll body outer layer according to
Secondary to be connected with main basic unit, wearing layer and stiffening layer, the main basic unit is combined one with wearing layer, stiffening layer.
Further, the roll mandrel is formed integrally with roll mandrel bearing rib roll neck, roll body.
Further, the main basic unit is made with wearing layer, stiffening layer of phase same material.
Further, the main basic unit can be made into integration with wearing layer, stiffening layer using graphitic steel.
Further, the main groundwork thickness is more than wearing layer, and the wearing layer thickness is less than stiffening layer.
Compared with prior art, beneficial effects of the present invention are：
The high hardness type steel roll of the present invention in roll body by setting main basic unit, wearing layer
With stiffening layer, shaped roll hardness can be effectively increased, so as to enhance the service life of roll.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Label in figure：
1-roll mandrel, 2-roll body 3-main basic unit
4-wearing layer, 5-stiffening layer.
Embodiment
Below to being elaborated with reference to accompanying drawing to presently preferred embodiments of the present invention, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, apparent is clearly defined so as to be made to protection scope of the present invention.
It is shown in Figure 1, a kind of high hardness type steel roll, including roll mandrel 1, roll body 2, main basic unit 3, wearing layer 4,
Stiffening layer 5, is connected with roll mandrel 1 in the roll body 2, and the outer layer of roll body 2 is connected with main basic unit 3, wear-resisting in turn
Layer 4 and stiffening layer 5, the main basic unit 3 are combined one with wearing layer 4, stiffening layer 5.
Preferably, the roll mandrel 1 is formed integrally with roll mandrel bearing rib roll neck 2, roll body 3.
Preferably, the main basic unit 3 is made with wearing layer 4, stiffening layer 5 of phase same material.
Preferably, the main basic unit 3 can be made into integration with wearing layer 4, stiffening layer 5 using graphitic steel.
Preferably, the thickness of main basic unit 3 is more than wearing layer 4, and the thickness of wearing layer 4 is less than stiffening layer 5.
The high hardness type steel roll of the present invention uses spinning process processing method, concretely comprises the following steps：It is made first for adding
The mould of work blank, blank to be processed is put on the spinning of spinning machine under mould and spinning between mould afterwards, starts spinning
Equipment, so as to which roll is made in spinning.
To sum up shown, high hardness type steel roll of the invention in roll body by setting main basic unit, wearing layer with adding
Hard formation, shaped roll hardness can be effectively increased, so as to enhance the service life of roll.
The foregoing is only the present invention better embodiment, protection scope of the present invention not using above-mentioned embodiment as
Limit, as long as equivalent modification that those of ordinary skill in the art are made according to disclosed content or change, should all include power
In protection domain described in sharp claim.
