Abstract
The invention discloses a kind of high-toughness wear-resistant roll, including roll axis body (1), it is characterised in that：The roll body being made of internal layer (2), intermediate layer (3), outer layer (4) is connected with the roll axis body (1), one is made with roll body in the roll axis body (1).The high-toughness wear-resistant roll of the present invention can make roll roll body have good high tenacity and wearability, excellent working performance by rational internal layer, intermediate layer, the compounded roll body of outer layer.
Description
Technical field
The present invention relates to a kind of roll, more particularly to a kind of high-toughness wear-resistant roll.
Background technology
Cast steel roll has higher tensile strength and toughness, is widely used in that rolling temperature is high, rolling loads are big opens
Base machine or blooming mill, it is also possible to do support roller.Alloy cast steel roll can make outside the body of roll according to its chemical composition and heat treatment process
Layer matrix is pearlite and bainite.Pearlite can be sheet or spherical, or sorbite type, and tempered sorbite is not
Only there is high obdurability, and there is good hot-cracking resistance, the especially tempered sorbite tissue with position phase also has concurrently excellent
Good wear-resisting property, therefore when being used for blooming mill, effect of rolling is good.
Traditional roll is generally made of cast iron, therefore low with manufacture efficiency, and poor product quality, poor toughness, makes
With short life, hardness is weak, the defects of wearing no resistance.
The content of the invention
The technical problems to be solved by the invention are to provide one kind and are combined by rational internal layer, intermediate layer, outer layer
Roll body, can make roll roll body that there is good high tenacity and wearability, the high-toughness wear-resistant roll of excellent working performance.
In order to solve the above technical problems, the present invention provides a kind of high-toughness wear-resistant roll, including roll axis body, its feature exist
In：The roll body being made of internal layer, intermediate layer, outer layer, the roll axis body and roll master are connected with the roll axis body
Made in one piece.
Further, intermediate layer, outer layer are connected with the internal layer in turn.
Further, the internal layer thickness is more than intermediate layer.
Further, the intermediate layer thickness is less than outer layer.
Further, the internal layer is identical with intermediate layer, outer layer chemical composition.
Further, the outer layer employs surface Hardening Treatment.
Further, the intermediate layer is made of high-toughness metal alloy material.
Compared with prior art, beneficial effects of the present invention are：
The high-toughness wear-resistant roll of the present invention passes through rational internal layer, intermediate layer, the compound system of outer layer
Into roll body, can make roll roll body that there is good high tenacity and wearability, work
Function admirable.
Brief description of the drawings
Fig. 1 is the structure diagram of the present invention.
Figure label：
1-roll, 2-internal layer of axis body
3-intermediate layer, 4-outer layer.
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-toughness wear-resistant roll, including roll axis body 1, be connected with the roll axis body 1 by
One is made with roll body in the roll body that internal layer 2, intermediate layer 3, outer layer 4 are formed, the roll axis body 1；On the internal layer 2
It is connected with intermediate layer 3, outer layer 4 in turn；2 thickness of internal layer is more than intermediate layer 3；3 thickness of intermediate layer is less than outer layer 4；Institute
It is identical with intermediate layer 3,4 chemical composition of outer layer to state internal layer 2；The outer layer 4 employs surface Hardening Treatment；Adopt in the intermediate layer 3
It is made of high-toughness metal alloy material；Internal layer 2, intermediate layer 3,4 thickness of outer layer are respectively 0.5-1cm, 0.2-0.4cm, 0.6-
1.2cm。
To sum up shown, high-toughness wear-resistant roll of the invention is by rational internal layer, intermediate layer, outer layer is compounded rolls
Roller main body, can make roll roll body have good high tenacity and wearability, excellent working performance.
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.
