Abstract
The invention discloses an automobile engine valve seat ring and a preparation method thereof and relates to the technical field of machinery manufacturing. The automobile engine valve seat ring is prepared from the following raw materials in percentage: 0.5-1.5% of C, 30-35% of Cr, 0.8-1.5% of Si, 0.8-1.5% of Mn, 0.01-0.04% of P, 0.2-0.5% of V, 5-7% of W, 0.2-3.5% of Ni and the balance of Fe. The produced valve seat ring is good in heat resistance, wear resistance and corrosion resistance.
Description
Technical field
The present invention relates to machinery manufacturing technology field, particularly relate to a kind of valve retainer for automobile engine and preparation method thereof.
Background technology
Valve retainer for automobile engine is parts important on engine, and enter the door of air and burning rear combustion gas when being automotive fuel burning, its main purpose is the sealing ensureing combustion chamber.Severe due to working conditions, needs impact, the wearing and tearing of bearing valve in high temperature environments, and the effect such as the erosion of inlet and outlet stream, oxidation, therefore, has high requirement to the characteristic such as high temperature resistant, wear-resistant, anti-oxidant of valve retainer.Along with the development of science and technology, people are more and more tighter to the requirement of engine valve retainer, wish that valve retainer has higher thermotolerance, wear resistance and erosion resistance.
Summary of the invention
For overcoming the deficiency in prior art, the object of the invention is to provide a kind of valve retainer for automobile engine and preparation method thereof.
For realizing object of the present invention, technical scheme of the present invention is as follows:
A kind of valve retainer for automobile engine, is made up of the raw material of following per-cent: C0.5 ~ 1.5%, Cr 30 ~ 35%, Si 0.8 ~ 1.5%, Mn 0.8 ~ 1.5%, P 0.01 ~ 0.04%, V 0.2 ~ 0.5%, W 5 ~ 7%, Ni 0.2 ~ 3.5%, surplus are Fe.
Preferably, be made up of the raw material of following per-cent: C1.5%, Cr 35%, Si 0.8%, Mn 0.8%, P 0.01%, V 0.5%, W 5, Ni 3%, surplus are Fe.
Prepare a method for valve retainer for automobile engine, comprise the following steps:
(1) preparation of valve retainer material: the mass percent of valve retainer material component is: C1.5%, Cr 35%, Si 0.8%, Mn 0.8%, P 0.01%, V 0.5%, W 5, Ni 3%, surplus are Fe;
(2) casting of valve retainer;
(3) thermal pretreatment of valve retainer: put in process furnace by valve retainer foundry goods, be heated to 550-600 DEG C, takes out after being then incubated 2-3h, completes the thermal pretreatment to valve retainer foundry goods;
(4) precision work of valve retainer;
(5) valve retainer after step (4) precision work is heated to 700-720 DEG C, in the isothermal salt bath of 250 DEG C, carries out isothermal, the time is 1-1.5h, then air cooling;
(6) valve retainer after step (5) process is slowly heated to 500-520 DEG C, after insulation 2-5h, air cooling of coming out of the stove.
Beneficial effect of the present invention: the present invention is directed to Problems existing, devises a kind of valve retainer for automobile engine and preparation method thereof, adopts valve retainer thermotolerance, wear resistance and good corrosion resistance prepared by this composition.
