Embodiment 1
[0020] The technical solution of the present invention is: a cylinder liner casting process, the process includes the following steps:
[0021] Step 1: Sand mixing, using resin sand as raw material, configuring casting sand according to the proportion, using dry clay sand to shape with a vibration molding machine, and making molding according to requirements to make a sand box;
[0022] Step 2: Mold making, making the cylinder liner inner mold casting mold and outer mold casting mold according to the size and shape of the cylinder liner, placing the inner mold casting mold inside the outer mold casting mold, and assembling to form a double-layer mold , placing the double-layer mold inside the sand box described in step 1;
[0023] Step 3: Smelting, configuring raw materials according to a certain ratio, heating the raw materials in an electric furnace to the melting temperature, and when the temperature in the melting furnace reaches 1300-1400°C, adding an inoculant for smelti...
