Embodiment 1
[0023] A casting process of a thermal crack resistant vermicular graphite cast iron brake disc, the casting process of the thermal crack resistant vermicular graphite cast iron brake disc comprises the following steps:
[0024] (1) Mix pig iron, low-carbon scrap steel, high-carbon chromium bearing steel, return material, recarburizer, ferrous sulfide, electrolytic copper, and high-carbon ferromanganese into an induction furnace to heat up to 1470-1490 °C for heat preservation and smelting. And in the process of heat preservation, impurity removal is carried out, and after heat preservation for 10-20min, molten iron is obtained for use;
[0025] (2) The above-mentioned molten iron is heated to 1510-1530°C, sampling is used to detect the content of its constituent substances by spectral analysis, the chemical composition is adjusted according to the detection results, and the smelting is continued for 10-15 minutes, and the original molten iron is obtained after slag removal;
