Abstract
The invention relates to an ultra-fine nanometer iron powder used in diamond saw plate, wherein it comprises at low frequency and high temperature, cutting the irregular sheet particles at 86 mum of iron powder into first powder; at high frequency and low temperature, cutting the irregular sheet particles at 86 mum of iron powder into second powder; then mixing them at 3:7. The inventive iron powder has better wetting property and high adhesive force on diamond particles, to reduce the inner tension between diamond particles and iron powder adhesive, to improve the service life of saw plate.
Description
Technical field
The present invention relates to a kind of ultrafine nanometer iron powder, be specially a kind of iron powder dedicated for diamond saw blade.
Background technology
Number of patent application is 2006100481685 to have put down in writing a kind of cutting production technology of metal nanometer powder zero boundry particle, a kind of brand-new zero boundry particle cutting metal nano-powder material technology has been put down in writing in this patent application, with the iron powder is example, step comprises, iron powder is placed under-10 ℃～+ 20 ℃ the zero boundary processing temperature state, then ferrous powder granules is carried out high speed and cut evil, per minute is controlled at 4000～6000 times (preferred 6000 times/minute), high frequency to the ferrous powder granules 4000～6000 rev/mins (preferred 4000 rev/mins) after the cutting grinds then, carry out the physics reduction again, surface treatment can obtain product, last classification and sorting.Mainly utilize high frequency cutting machine and grinder, can process the iron powder of different Nano grades, utilize the iron powder of the specific particle diameter that this method produces to have the different excellent specific property of material that conventional art is produced, the nanometer iron powder characteristic of each different stage that this explained hereafter goes out has tangible difference, through being widely used in different industries or field after sizing screening and the proportioning.
In the powder body material of domestic present production diamond saw blade, have 20%---30% iron powder that does not wait.The iron powder that adopts all is inequilateral sheet-like particle powders, and this kind powder causes saw blade in cutting process because its grain shape lacks enough mechanical strengths, and the wear-resisting time has only 1/6 of Japan, Germany, product.Saw blade in cutting process because wear-resisting time short, so clipping time not enough external like product 38%.Because the grain shape of the iron powder that uses all be an inequilateral sheet shape in the saw blade, the close capacitive energy of it and Buddha's warrior attendant sand is relatively poor, so saw blade diamond particles in cutting process is very easy to come off, causes saw blade just can't effectively cut than the time of weak point.Because the mechanical strength of ferrous powder granules deposit was not enough during saw blade was made,, finally cause shorten greatly the normal service life of saw blade so saw blade connecting portion of sawtooth and substrate in cutting is very easy to fracture.
Summary of the invention
The present invention provides a kind of iron powder dedicated for diamond saw blade in order to solve the ropy problem of using in the preparation diamond saw blade that exists in the prior art of iron powder.
The present invention is realized by following technical scheme, and a kind of iron powder dedicated for diamond saw blade is to be made by following method:
In frequency is that 1200 times/minute-1800 times/minute and temperature are controlled under the condition of 28 ℃-10 ℃ (preferred 10-20 ℃), the irregular sheet-shaped material ferrous powder granules of 86 μ m is cut into the irregular slightly spherical particle material of D50=74 μ m, as No. 1 powder, be controlled in high-frequency 4000 times/minute-5000 times/minute and temperature under-3 ℃-16 ℃ the situation, the irregular sheet-shaped material ferrous powder granules of 86 μ m is cut into D50=46 μ m spherical particle material, as No. 2 powder, 1, No. 2 iron powder is uniformly mixed to form iron powder dedicated for diamond saw blade in 3: 7 ratio.
Technology of utilizing " cutting production technology of metal nanometer powder zero boundry particle " to go up record be basic, produces 1, No. 2 iron powder and is uniformly mixed to form iron powder dedicated for diamond saw blade in 3: 7 ratio.Behind the shaping saw blade, observation by 500,000 times of Electronic Speculum, special-purpose powdered iron has wettability preferably to diamond, formability, sinterability, bigger adhesive force, relatively more suitable mechanical property is arranged, as mechanical strength, hardness, the cracking resistance bending strength, substrate material there are wettability and compatibility preferably, strong reduction the inner boundary tension force of diamond and iron powder binding agent, thereby improved adamantine cohesive force greatly, reduced the phenomenon that saw blade diamond in cutting falls grain, improved the service life of saw blade significantly, simultaneously can also reduce copper powder consumption 3%, reduce cobalt powder 1.2%, improve 5.3 times service life, the monolithic cost reduces by 11.59%, abrasion resistance has improved 6 times, and cutting speed has improved 55%, and the sawtooth fracture rate drops to 1% from original 12%.By comparing with German, Japanese like product, with the saw blade that " special-purpose powdered iron " produced, leading indicator all reaches the technical indicator of external like product.Wherein abrasion resistance surpasses 2.1 percentage points in Germany, surpasses 3.2 percentage points in Japan.This method has changed those skilled in the art's mindset, and the Apparatus and method for that will be used for cutting inorganic material is applied to the cutting processing field of inorganic metal material, has realized the Physical Processing of metal nano level powder.
