Abstract
The present invention mainly relates to diamond saw blade matrix steel which belongs to the field of alloy steel. The diamond saw blade matrix steel comprises 0.35 to 0.65 wt% of C, 0.10 to 0.35 wt% of Si, 1.2 to 2.0 wt% of Mn, 0.06 to 0.20 wt% of V, 0.02 to 0.06 wt% of Al and Fe as the rest. After smelting and ingot casting, the diamond saw blade matrix steel is rolled at high temperature into plates to form blanks of diamond saw blade matrices, and then, the blanks of matrices are quenched and tempered to form diamond saw blade matrices. The diamond saw blade matrix steel of the present invention has the advantages of proper strength, low ratio of strength to toughness, favorable plastic toughness and heat stability, so that the service life of a product made of the diamond saw blade matrix steel is extended.
Description
Technical field
The invention belongs to field of alloy steel, relate generally to matrix steel for diamond sawblade.
Background technology
Diamond saw blade is in nonmetal hard building material field widespread uses such as stone material, cement products.Diamond saw blade is made up of diamond block and saw bit matrix two portions, and both can engage by sintering process, ratio-frequency welding connection and method of laser welding and form.
As the steel grade of diamond saw blade substrate, both required to have enough intensity and good plasticity and toughness, also require to have higher hardening capacity and thermostability.
In the prior art, matrix as diamond saw blade, generally adopt all steel grades more than 0.65 (wt%) (as 65Mn, SKS5, SKS51,15LM, 80CrV and 75Cr1 etc.) of carbon content, these steel all belong to high carbon tool steel and high-carbon low-alloy tool steel class, are characterized in the intensity height, intensity/toughness is than high, plasticity and toughness are low, as diamond saw blade substrate, are prone to crackle in process of production, be difficult for smoothing, work-ing life is low; Should not adopt advanced method of laser welding etc. to engage.
Summary of the invention
The object of the present invention is to provide a kind of both had proper intensity and lower intensity/toughness ratio, plasticity and toughness are preferably arranged again, and the matrix steel for diamond sawblade of good thermally-stabilised and hardening capacity.
At above-mentioned purpose, the Chemical Composition of the matrix steel for diamond sawblade that the present invention is designed (weight %) is:
C 0.35～0.65%, and Si 0.10～0.35%, and Mn 1.3～2.0%, and V 0.06～0.20%, Al0.02～0.06%, and surplus is Fe.
Can be designated as the 50Mn2VAl steel according to above-mentioned Chemical Composition steel of the present invention, the present invention adopts medium carbon content, manganese addition, vanadium, aluminium.
Middle carbon manganese addition can improve the hardening capacity of steel, guarantees proper intensity.
Adding V, Al then can crystal grain thinning, and in the smelting process of steel, the C in V and the molten steel forms VC, and Al then forms AlN, Al with N and O
2O
3, VC and AlN, Al
2O
3All be thinner particle, be distributed on the crystal boundary, cause the grain refining of steel, improve the plasticity and toughness of steel greatly, make it lower intensity/toughness ratio.
This steel also has thermostability preferably owing to the refinement of crystal grain, and it is overheated therefore to be difficult for causing when quenching heating and welding heating, can keep stable performance, is not prone to crackle.And higher because of impelling strength, also be difficult for collapsing tooth.
The manufacture method of matrix steel for diamond sawblade 50Mn2VAl of the present invention is as follows:
1, smelts
This steel can adopt converter or electrosmelting, is cast into ingot or continuously cast bloom afterwards.
2, rolling
Ingot casting or Hot Charging of Continuous Casting Slab are rolled into sheet material.
3, thermal treatment
Sheet material after the hot rolling is quenched and tempering heat treatment, and the processing parameter of its Q-tempering is as follows:
Quenching process parameters: Heating temperature: 800～860 ℃, heat-up time: 10～40 minutes, quenchant was a machine oil.
Tempering process parameters: Heating temperature: 350～460 ℃, tempering time: 2～5 hours
Hot-rolled sheet with matrix steel for diamond sawblade of the present invention is a blank, after heat treatment can obtain the mechanical property shown in the table 1.
Table 1: the mechanical property after the thermal treatment of the present invention
| σ b Mpa | σ s MPa | δ 5 ％ | ψ ％ | α k J/cm 2 | HRC |
| 1400～1520 | 1300～1450 | 10～15 | 40～55 | 40～55 | 41～46 |
Compared with prior art, the present invention has following advantage:
1, existing proper intensity and lower intensity/toughness ratio have plasticity and toughness preferably again, make it not to be prone to crackle in the manufacturing processed as diamond saw blade substrate, be out of shape little, the yield rate height.
2, because matrix steel has thermally-stabilised preferably and hardening capacity, in the time of guaranteeing to be used for saw bit matrix, be easy to smoothing, make it to reach and hold jumping, tension value, recovery and planeness index preferably, and have better stability.
Embodiment
Adopt Chemical Composition of the present invention and production method, produced 3 stoves (promptly 3 batches) matrix steel for diamond sawblade.The Chemical Composition of 3 stove steel is as shown in table 2.3 stove steel through smelt, ingot casting, and be rolled into the thick sheet material of 5mm, the hot-rolled sheet thick with this 5mm is the matrix blank, heat-treats then.The process of thermal treatment parameter is as shown in table 3.3 batches of matrixes are taken a sample after treatment, are processed into corresponding sample, carry out mechanical properties test, and its result lists table 4 in.
The Chemical Composition (weight %) of table 2 embodiment steel grade
| Become stove part number | C | Si | Mn | V | Al | Fe |
| 1 | 0.60 | 0.21 | 1.30 | 0.14 | 0.04 | Surplus |
| 2 | 0.51 | 0.19 | 1.40 | 0.12 | 0.03 | Surplus |
| 3 | 0.39 | 0.23 | 1.60 | 0.12 | 0.05 | Surplus |
