Description
Technical field
The present invention relates to a kind of roll, more particularly to a kind of high strength type steel roll.
Background technology
Roll is the important tool of Rolling production, reduces the effective cost efficiency of roller energy consumption, improves operating rate of rolling mill, improve
Rolled piece product quality, reduces the labor intensity of worker.Heavy steel rolling mill steel section shop roll mainly includes at present：Universal mill rolls
Roller and straightening 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 conditions, 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 intensity is low, and manufacture is of high cost, and manufacturing process is complicated, and service life is short.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of roll mandrel and are adopted with roll mandrel bearing rib roll neck, roll body
It is made into integration with graphitic steel, the high strength type steel roll with the advantages of intensity height, service life is long.
In order to solve the above technical problems, the present invention provides a kind of high strength type steel roll, including roll mandrel, roll axle bearing
Block roller neck, roll body, opening, groove, it is characterised in that：The roll body both ends are connected to a roll mandrel bearing rib
Roll neck, described roll mandrel bearing rib roll neck one end are connected with roll mandrel, opening, the roll body are offered on the roll mandrel
On offer multiple irregular grooves.
Further, one is made with roll mandrel bearing rib roll neck, roll body in the roll mandrel.
Further, the roll mandrel is made with roll mandrel bearing rib roll neck, roll body of phase same material.
Further, the roll mandrel can be made into integration with roll mandrel bearing rib roll neck, roll body using graphitic steel.
Compared with prior art, beneficial effects of the present invention are：
The roll mandrel of the present invention is with roll mandrel bearing rib roll neck, roll body using graphitic steel one
It is made, there is the advantages of intensity is high, and service life is long.
Brief description of the drawings
Fig. 1 is the structure diagram of the present invention.
Figure label：
1-roll mandrel, 2-roll mandrel bearing rib 3-roll body of roll neck
4-opening, 5-groove.
Embodiment
Below to being elaborated with reference to attached 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 strength type steel roll, including roll mandrel 1, roll mandrel bearing rib roll neck 2, roll body
3rd, opening 4, groove 5,3 both ends of roll body are connected to a roll mandrel bearing rib roll neck 3, the roll mandrel bearing rib
3 one end of roll neck is connected with roll mandrel 1, and opening 4 is offered on the roll mandrel 1, offers and multiple does not advise in the roll body 3
Then groove 5.
Preferably, one is made with roll mandrel bearing rib roll neck 2, roll body 3 in the roll mandrel 1.
Preferably, the roll mandrel 1 is made with roll mandrel bearing rib roll neck 2, roll body 3 of phase same material.
Preferably, the roll mandrel 1 can be made into integration with roll mandrel bearing rib roll neck 2, roll body 3 using graphitic steel.
The processing method of the present invention：Blank to be processed is put between the spinning upper mold of spinning machine and spinning lower die,
Start spinning machine, so that high strength type steel roll is made in spinning.
To sum up shown, roll mandrel of the invention is made into integration with roll mandrel bearing rib roll neck, roll body using graphitic steel,
With the advantages of intensity height, service life is long.
The foregoing is merely the present invention better embodiment, protection scope of the present invention not using the above embodiment as
Limit, as long as those of ordinary skill in the art's equivalent modification that disclosure is made according to the present invention or change, should all include power
In protection domain described in sharp claim.
