Abstract
The invention relates to a low-carbon and low-silicon cylinder sleeve which comprises the chemical components by weight percent: 2.5-2.7% of C, 1.3-1.7% of Si, 0.5-0.9% of Mn, more than 0% and less than or equal to 0.1% of S, more than 0% and less than or equal to 0.1% of P, more than 0% and less than or equal to 0.1% of Ni, more than 0% and less than or equal to 0.2% of Cr, more than 0% and less than or equal to 0.1% of Mo, 0.4-1.0% of Cu and the balance of Fe. On the premise of low cost, higher mechanical performance requirements (including hardness and tensile strength) of the cylinder sleeve can be met, and the cylinder sleeve is high in cost performance, so that the low-carbon and low-silicon cylinder sleeve has high potential market.
Description
Technical field
The invention belongs to the cylinder sleeve technical field, be specifically related to a kind of low carbon low silicon cylinder sleeve and preparation method thereof.
Background technology
At present, on the market there be the alloy cast iron cylinder jacke of several kinds of common low carbon low silicons: material cylinder sleeve such as middle phosphorus alloy cast iron, boron cast iron, high phosphorus cast alloy iron, phosphorus molybdenum alloy cast iron.Support cylinder sleeve in being all, their material cost is all higher, mainly strengthens the intensity of pearlite matrix through other alloy.Higher like Cr content in the high-phosphorous iron, the phosphorus molybdenum alloy cast iron need add the intensity that the noble metal molybdenum increases cylinder sleeve.
Though above-mentioned material cylinder sleeve can satisfy the requirement of engine strength aspect, during all can't avoiding, these materials support the vibrations of cylinder sleeve and mover contact position.The fatigue strength of these cylinder sleeves is not high yet in addition, generally about 150Mpa.The vibrations reason is that the Young's modulus (in close relations with Chemical Composition) of cylinder sleeve is lower, generally between 120-150Gpa.Young's modulus is low, and the rigidity of cylinder sleeve is just little, in engine working process, just is prone to produce distortion, thereby just is prone to produce vibrations at the mating surface place.
Summary of the invention
The object of the invention is to provide a kind of low carbon low silicon cylinder sleeve and preparation method thereof, and this cylinder sleeve has better tensile strength, consistency and elasticity modulus.
For realizing above-mentioned purpose, the technical scheme that the present invention takes is following:
A kind of low carbon low silicon cylinder sleeve, its materials chemistry are formed meter as following weight percent:
Carbon (C) 2.5~2.7%, silicon (Si) 1.3~1.7%, manganese (Mn) 0.5~0.9%, 0<sulphur (S)≤0.1%, 0<phosphorus (P)≤0.1%, 0<nickel (Ni)≤0.1%, 0<chromium (Cr)≤0.2%, 0<molybdenum (Mo)≤0.1%, copper (Cu) 0.4~1.0%, surplus is Fe.
The preparation method of said low carbon low silicon cylinder sleeve, it comprises the steps:
1. prepare burden in proportion, with line frequency furnace melting batching, control iron liquid tapping temperature is 1530~1550 ℃;
2. the nucleating agent that adds iron liquid weight 0.2~0.5% before coming out of the stove is handled, and said nucleating agent is silicon barium calcium nucleating agent or silicon strontium nucleating agent;
3. adopt metal mold coating centrifugal casting technique (this technology is common process, so do not give unnecessary details) the production cylinder sleeve cast part (die temperature is advisable to be controlled at 400~600 ℃) that wets;
4. foundry goods depanning after wind is chilled to 550~650 ℃, puts into the foundry goods frame then and gets final product.
Cylinder sleeve according to the invention has reduced carbon, the silicone content in " carbon, silicon, manganese, sulphur, phosphorus " five big common elements; Add copper alloying in addition; The main effect of these three kinds of elements is following: the 1) effect of copper: copper belongs to graphite element; Can reduce austenite critical transition temperature and reinforced ferrite matrix, but and refine pearlite and graphite flake.Promptly play the solution strengthening effect at the thin-walled place, perlite hardness is increased at pearlite region copper; At the heavv section place, it mainly acts on is to suppress ferritic transformation, thereby improves sensitivity profile.2) effect of carbon and silicon: silicon and carbon all are the strong graphited elements that promotes.Graphite derives from carbon.Along with the raising of carbon content, carbon concentration in the molten iron and undissolved graphite particulate increase, and help the graphite forming core, thereby have promoted greying.The bonding force of silicon and iron atom is greater than the bonding force between carbon and the iron atom.Silicon is dissolved in the sosoloid of molten iron and iron, owing to weakened the bonding force between iron and the carbon atom, and impel greying.Silicon also reduces the carbon concentration of cast iron eutectic composition, adds silicon in the cast iron and can replace a part of carbon, and silicon promotes graphited effect to be equivalent to 1/3rd of carbon approximately.
Cylinder sleeve performance index according to the invention are following: 1) Young's modulus: E >=160Gpa.High Young's modulus can guarantee high rigidity, and the distortion that cylinder sleeve produces at work reduces, thereby supports moving, shaking of cylinder sleeve and engine cylinder contact level in can reducing, and avoids the wearing and tearing of cylinder sleeve to cylinder body.2) hardness 250~300HBW; Tensile strength >=330Mpa; Fatigue strength 165Mpa.This cylinder sleeve also has higher fatigue strength outside guaranteeing high hardness and tensile strength.
With respect to prior art, the present invention has the following advantages:
The cost of material is low for cylinder sleeve of the present invention; Only in cylinder sleeve five big conventional elements, add a certain amount of Cu, under satisfied prerequisite cheaply, can satisfy the cylinder sleeve higher mechanical properties again and require (comprising hardness, tensile strength); Cost performance is high, has enormous and latent market.
