Abstract
The invention discloses a TiC-treated cast iron cylinder casing and its producing method. The cylinder casing contains the following elements: C 3.1-3.4%; Si 1.9-2.3%; Mn 0.7-1.0%; P 0.2-0.4%; S 0-0.08%; Ti 0.25-0.35%; Fe 92.47-93.85%. The producing method of the inventive cylinder casing includes the steps: firstly, TiC is processed to granules with granularity of 2-3mm for reservation; and then the alloy is dosed pro rata and smelted, and TiC granules are added pro rata into it at the temperature of 1550 DEG C, refining them for five minutes after adding granules; at last, pouring, rough machining and fine machining are performed based on traditional arts. The inventive cylinder casing can improve the service performance of engine, prolong the service life, reduce energy consumption, improve the offgas quality from engine, and protect natural environment.
Description
Technical field
The present invention relates to cylinder sleeve and synthetic method, be specifically related to cast iron cylinder cover and synthetic method thereof that a kind of TiC handles.
Background technology
Cylinder is the space of gas compression, burning expansion, and piston motion is play the guiding role.The highest transient temperature of combustion gas can reach 2000～2500 ℃ in the combustion processes, and the highest transient pressure can reach 10～15Mpa, so its inwall directly is subjected to the effect of high temperature, high-pressure gas, and its outer wall is subjected to the cooling of water coolant.Under inside and outside wall thermograde and explosion pressure effect, cylinder sleeve is subjected to sizable thermal stresses and mechanical pressure, and piston makes cylinder-barrel surface be subjected to strong friction in its surperficial high speed to-and-fro movement.
Cylinder sleeve is one of important friction pair of engine, and its wear resistance will directly have influence on the consumption of life-span, power, fuel oil and the machine oil of engine.Along with improving constantly of engine reinforcing degree, mechanical stress that its cylinder sleeve, piston, piston ring bore and thermal stresses are more and more high, and the wearing and tearing of the wearing and tearing, particularly inboard wall of cylinder liner of the cylinder of diesel engine internal friction pair that causes therefrom are even more serious.
Material cylinder sleeve such as the traditional high-phosphorous iron of China, boron cast iron, vanadium-titanium cast iron, low-alloy cast iron have not adapted to the demand of present high-grade engine with supercharger.Its main wear form has: abrasive wear, be stained with layer wearing and tearing, the wearing and tearing of stripping layer and corrosive wear etc.Piston movement speed, explosion pressure all are greatly improved along with improving constantly of diesel engine strengthening in recent years, so the wear problem of cylinder sleeve is also serious day by day.Therefore, it is very important developing wear-resistant type cylinder sleeve.
Summary of the invention
The invention provides cast iron cylinder cover and synthetic method thereof that a kind of TiC handles, adopt this kind cylinder sleeve to improve the engine use properties, increase the service life, reduce energy consumption, improve the engine exhaust emission quality, the conservation of nature environment.
Technical solution of the present invention is to contain following element: C3.1～3.4% in this cylinder sleeve; Si 1.9～2.3%; Mn 0.7～1.0%; P 0.2～0.4%; S 0-0.08%; Ti 0.25～0.35%; Fe 92.47～93.85%.
The synthetic method of cylinder sleeve of the present invention is: at first TiC is processed into particulate state, and granularity is that 2-3mm is standby; Alloy is prepared burden and melting in proportion then, adds the TiC particle when the electric furnace molten iron temperature reaches 1550 ℃ in proportion, and particle added after 5 minutes, at last according to traditional technology pour into a mould, roughing, finishing step.
The present invention has the following advantages: 1. original position is synthesized the TiC particle in cast iron solution, and particle dispersion is even, the dense structure of cylinder sleeve, and Heat stability is good has good oil storage capacity and excellent abrasive energy and good antiacid rotten ability; 2. the flow process of synthetic method is simple, and cost is low, is easy to realize industrialization production; 3. TiC is strong graphite element, has refinement graphite and strengthens pearlitic effect, forms stable especially high-intensity titaniferous carboritride, and disperse is dispersed in the Cast iron liner matrix, strengthens wear resistance.
