Abstract
The invention relates to a valve component for a high pressure water atomization pulverizing technology The valve component comprises, by mass percentage, 0.7%-1.3% of C, 1.4%-3.2% of Cr, 0.5%-1.2% of Ni, 1.4%-3.2% of Mo, 1.4%-3.3% of Co, 14%-33% of Cu and the balance Fe. By means of the valve component, the abrasive resistance, the high-temperature resistance, the corrosion resistance and the radial conquassation intensity of products can be improved.
Description
Technical field
The present invention relates to metallurgical technology field, especially relate to a kind of valve parts of hydraulic atomized powder-making technique.
Background technology
In prior art, the low-alloy powder that base iron adopts water atomization to make, valve seating base is relatively soft through organizing of sintering formation, and the wear resisting property of its valve seating is poor, and high temperature stability performance is also poor, and after work certain hour, valve easily sinks.White gasoline superpower, the engine of high strength and high-power, high loading diesel motor can not be widely used in.
In view of this, how designing a kind of High abrasion resistant metallurgy valve seat, to increase the wear resistance of product, high thermal resistance, erosion resistance and radial crushing strength, is the problem that insider's letter need solve.
Summary of the invention
For in prior art, the wear resisting property of valve seating is poor, and high temperature stability performance is the defect such as poor also, the invention provides a kind of valve parts of hydraulic atomized powder-making technique.
The present invention also provides a kind of valve parts of hydraulic atomized powder-making technique, and by percentage to the quality, its chemical composition comprises: the C of 0.7 ~ 1.3%; The Cr of 1.4 ~ 3.2%; The Ni of 0.5 ~ 1.2%; The Mo of 1.4 ~ 3.2%; The Co of 1.4 ~ 3.3%; The Cu of 14 ~ 33%; Surplus is Fe.
Advantage of the present invention:
The present invention can increase the wear resistance of product, high thermal resistance, erosion resistance and radial crushing strength.
Accompanying drawing explanation
Below in conjunction with drawings and the embodiments, the present invention is further detailed explanation.
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
First will the basic Fe powder of hydraulic atomized preparation be adopted to allocate a certain amount of high alloy powder (Cr, Ni, Mo into, Co) suppress after mixing 32 minutes, after compacting, sintered blank is placed in push-down sintering oven to sinter, in ammonia dissolving atmosphere, sintering temperature is 11015C.Valve seating containing phase constitution be perlite+ferrite+alloy deposition phase+copper phase.
According to hypervelocity long duration test specification, by the valve seating product in above-described embodiment on test-bed at full speed full load (specified speed (r/min) is: 6500, rated output (KW) is: 70, maximum twist (N.m) is: 127), accumulative operation (wherein break-in 24 hours 25 minutes in 335 hours, external characteristics tests 1 hour 45 minutes, strenuous test 310 hours).Through folding machine testing, the performance of valve seating in each embodiment.
