Abstract
The present invention provides a kind of high silicon steel, it is characterised in that is made of the chemical element of following weight percentage：C：0.76~0.85%, Si：0.80~0.90%, Mn：0.25~0.40%, Cr：6.0~6.8%, W：1.6~2.5%, Mo：4.2~5.2%, V：0.7~0.9%, Nb：0.1~0.2%, Co 0.3~0.4%, S≤0.02%, P≤0.025%, remaining is Fe；This high-speed steel of the present invention, hardness toughness is higher, and surface particles uniform and smooth, can obtain high quality high-speed steel bit.
Description
Technical field
The present invention relates to a kind of high silicon steel.
Background technology
The performance of paper cutting blade should have high sharpness and wearability, also have the good anti-impact for not collapsing and not rolling up
Hitting property and certain thermohardening.Holding cutting edge sharpness and sharpening property are particularly significant when paper cutting blade is sheared, and high-speed steel quenches back
Remaining carbide volume fraction after fire is between 15%~22%, and remaining carbide size is 2.5um~15um, the carbon of cutting edge
Compound easily comes off, and can both reduce sharpness, also easily causes chipping in shear history.In recent years, our research and point
Analysis demonstration thinks, if using suitable semi-high speed steel shear-steel, reduces in shear-steel carbide quantity between 3%~8%, matrix
Q-tempering hardness keeps the level of high-speed steel again, can be conducive to improve paper cutting blade sharpness, durability and be sheared face light
Cleanliness, and the alloy amount cost of shear-steel is reduced, also improve anufacturability.It is existing both at home and abroad to be applied to other tool and moulds
Semi-high speed steel patent and technology report it is more, but be all not suitable for the carbide size and quantative attribute of paper cutting blade shear-steel, also
Some lower hardness.
The content of the invention
The object of the present invention is to provide a kind of high silicon steel, hardness toughness is higher, and surface particles uniform and smooth, can obtain
High quality high-speed steel bit.
A kind of high silicon steel, is made of the chemical element of following weight percentage：C：0.76~0.85%, Si：0.80~
0.90%, Mn：0.25~0.40%, Cr：6.0~6.8%, W：1.6~2.5%, Mo：4.2~5.2%, V：0.7~0.9%,
Nb：0.1~0.2%, Co0.3~0.4%, S≤0.02%, P≤0.025%, remaining is Fe.
It is made of the chemical element of following weight percentage：C：0.76~0.85%, Si：0.80~0.90%, Mn：
0.35~0.40%, Cr：6.0~6.8%, W：1.6~2.2%, Mo：4.2~5.2%, V：0.7~0.9%, Nb：0.1~
0.2%, Co0.3~0.4%, S≤0.02%, P≤0.015%, remaining is Fe.
Compared with prior art, this high-speed steel of the present invention, hardness toughness is higher, and surface particles are even and fine
It is greasy, high quality high-speed steel bit can be obtained.
Embodiment
The present invention is described further with reference to embodiment：
(1) semi-high speed steel shear-steel is produced：Using high by electroslag remelting production half after electric induction furnace or electric induction furnace smelting
Fast steel shear-steel, (2) forging rolling process：By step (1) production semi-high speed steel shear-steel carry out forging rolling, its forging rolling temperature for 870 DEG C~
1080℃；(3) anneal：Semi-high speed steel shear-steel after step (2) forging rolling is heated to 850 DEG C~860 DEG C, when insulation 4~6 is small after
Furnace cooling.
This high-speed steel of the present invention, hardness toughness is higher, and surface particles uniform and smooth, can obtain high quality
High-speed steel bit.
The foregoing is merely one embodiment of the invention, is not intended to limit the present invention, all to use equivalent substitution or equivalent transformation
The technical solution that is obtained of mode, all fall within protection scope of the present invention.
Claims (2)
