Abstract: The purpose of the present invention is to provide a method for reducing the surface roughness and deformation of gray cast iron parts, the method capable of improving the defects of surface roughness due to a porous layer (Fe2N of an epsilon phase) which may be produced during the heat treatment of gray cast iron materials without a post-process or a micro preprocess. The method for reducing the surface roughness and deformation of gray cast iron parts according to the present invention achieves its purpose by comprising a step for performing finishing to obtain a processing dimension of the parts within the range of -1 to 0 mm based on the criteria of complete products before surface heat treatment of the gray cast iron parts; a step for suppressing Fe2N maximally by plasma-ionnitriding the finished gray cast iron parts; and a step for grinding the Fe2N on the surface of the parts after the surface heat treatment. The method for reducing the surface roughness and deformation of gray cast iron parts reduces a gas pocket layer by maximally suppressing the Fe2N of an epsilon phase, thereby minimizing the surface roughness and deformation.

The present invention provides an apparatus for efficiently removing the hidden residual stress during manufacturing a gray cast iron component that makes the new technology of removing residual stress which allows residual stress hidden in a component to be exhausted by itself by applying vibration energy to the component for a short period of time at the general low temperature (0 to 300) when the residual stress of the gray cast iron component is removed. Therefore, the residual stress hidden in the component is efficiently removed. The quality is ensured, such as suppressing the dimension change before and after stress removal. Above all, the process is performed for a short period of time at the low temperature, thereby reducing productivity and costs. The process of removing residual stress using vibration and the process of heat treatment, such as oxy-nitriding, are simultaneously performed in a furnace, thereby improving the productivity by reducing the number of process.
