Embodiment
To make the object, technical solutions and advantages of the present invention of greater clarity, with reference to embodiment and join
According to attached drawing, the present invention is described in more detail.It should be understood that these descriptions are merely illustrative, and it is not intended to limit this hair
Bright scope.In addition, in the following description, the description to known features and technology is eliminated, to avoid this is unnecessarily obscured
The concept of invention.
Fig. 1 is the process flow chart of the production method of the bimetallic hybrid engine cylinder body of the present invention.
As shown in Figure 1, the present invention bimetallic hybrid engine cylinder body production method, it is described including：
Step S1, under 1480 DEG C of -1500 DEG C of temperature environments, height is made by liquid rich chromium cast iron using centrifugal casting process
Chrome cast iron cylinder barrel.
In this step, under 1480 DEG C of -1500 DEG C of temperature environments, liquid rich chromium cast iron is made by Gao Ge using centrifugal method
Cast iron cylinder barrel, rotating speed turn/min for 900 turns/min-1500.Specifically, liquid rich chromium cast iron is placed in rotating mould, mould
The rotating speed of tool turns/min for 900 turns/min-1500, makes liquid rich chromium cast iron that rich chromium cast iron cylinder be made under the influence of centrifugal force
Cylinder.
Centrifugal casting has following Some features：
1) liquid metals can form hollow cylindrical Free Surface in casting mold, can so not have to core with regard to that can cast out
Hollow casting, enormously simplify the production process of casting；
2) centrifugal force caused by liquid metals acts on when due to rotation, and centrifugal casting technique can improve metal and fill town casting mold
Ability；
3) due to the effect of centrifugal force, feeding condition is improved, gas and nonmetal inclusion are also easy to from liquid metals
Discharge, therefore the tissue of centrifugal casting is finer and close, and shrinkage cavity (shrinkage porosite), stomata, the defects of being mingled with are less.Step S2, cylinder body are made
Afterwards, roughing is carried out to the cylinder body and stays allowance.
After rich chromium cast iron cylinder barrel is made, roughing further is carried out to the rich chromium cast iron cylinder barrel and stays allowance.Can
Choosing, for the thickness of the rough machined allowance between 3mm-5mm, the purpose for staying allowance is to prevent from subsequently carrying out heat
When processing and finishing, rich chromium cast iron cylinder barrel is shunk.
Step S3, after roughing, is heat-treated the rich chromium cast iron cylinder barrel.
In this step, after carrying out roughing to the rich chromium cast iron cylinder barrel, further the rich chromium cast iron cylinder barrel is carried out
Heat treatment, by heat treatment, makes rich chromium cast iron cylinder body have required mechanical property, physical property and chemical property.
