Example Embodiment
[0033] Example 1
[0034] The manufacturing composition is C: 3.15%; Si: 1.80%; CE: 3.75%; Mn: 0.80%; P≤0.07%; S: 0.06%; Cu: 0.50%; Cr: 0.20%; cast iron:
[0035] The first step, modeling and core making: resin sand is used for modeling and core making, and the surface of the cavity is painted with alcohol-based graphite paint. The important parts should be painted twice. When painting the paint, the surface should be smooth and the edges and corners are clear; The use surface of iron and cold iron should be flat and free of defects such as oil stains, pores, rust, and defects;
[0036] The second step, preparation of raw materials: Weigh the raw materials according to the weight percentage of "carbon scrap: high-purity pig iron: returning material = 60%: 5%: 35%", wherein: the chemical composition of high-purity pig iron is: C: 4.61% ;Si: 0.62%; Mn: 0.08%; S: 0.026%; P: 0.011%; Ti: 0.030%, the balance is Fe; the chemical composition of carbon scrap is: C: 0.16%; Si: 0.23%; ...
