Description

A kind of fly wheel casing of marine engine

Technical field:

The present invention relates to internal combustion engine part processing technical field, be specifically related to a kind of fly wheel casing of marine engine.

Background technology:

Oil engine is the one of heat engine, can by the chemical energy mechanical energy of fuel.General implementation is, fuel and air mixed are burnt, and produce heat energy, when gases are heated, they expand, is converted into mechanical energy externally does work by mechanism.Oil engine has application widely, and the engine of automobile, boats and ships, aircraft, rocket etc. is substantially all oil engine, and its modal example is vehicle gasoline engine and diesel engine.The combustion gases of oil engine are also working mediums simultaneously, and in such as petrol motor, the gas after gasoline combustion directly promotes piston acting.On the other hand, fuel is not then called external combustion engine as the heat engine of working medium, and the working medium (steam) of such as steamer is not fuel.

And the use of oil engine very extensive, but the material of the various shells outside different field oil engines is also different, many oil engines and the life-span of shell are not very long, are because the reason of material on the one hand, also have incorrect when using causing.

Summary of the invention:

Technical problem to be solved by this invention be to overcome existing technological deficiency provide a kind of composition rationally, the fly wheel casing of a kind of marine engine of better resistance, long perfomance life.

Technical problem to be solved by this invention adopts following technical scheme to realize:

A fly wheel casing for marine engine, is characterized in that: comprise following material,

The present invention also provides a kind of preparation method of fly wheel casing of marine engine, comprises the following steps,

Step one, the process furnace first pig iron being put into 300 DEG C heat 15-23 minute, then take out the pig iron of high temperature, put into rolling device and pulverize, keep temperature-resistant;

Step 2, aluminum magnesium alloy, diamond are put into rolling device respectively pulverize, then asbestos are put into pulverizer pulverize;

Step 3, by the aluminum magnesium alloy after pulverizing with pulverize after asbestos and silicone oil put into forming machine, and then put into oxidation inhibitor, diamond, volatile salt, the pig iron successively, extrusion molding;

Step 4, the cryostat material after shaping directly being put into 0 ° cool 8-11 minute rapidly;

Step 5, the heating container then cooled material being put into 200-235 ° heat 18-26 minute;

Step 6, by heating after material continue extrusion molding, then punch, naturally placement.

Beneficial effect of the present invention is: owing to being device peculiar to vessel, oxidation inhibitor and anti-aging agent effectively can prevent the bedroom of seawater or fresh water, the work-ing life of material can be increased, and the hardness of above-mentioned metallic substance is all very high, also distortion is not easy, and resistance all very good, and asbestos have good tensile strength and good thermal insulation and non-corrosibility, nonflammable.Present component is reasonable, better resistance, long perfomance life.

Embodiment:

The technique means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, setting forth the present invention further below.

A fly wheel casing for marine engine, is characterized in that: comprise following material,
