Embodiment 1
[0027] A casting casting process, characterized in that: comprising the following steps:
[0028] (1) Smelting: Melt the steel in an electric furnace. When the temperature rises to 1600°C, add a refining agent and refine for 15 minutes to obtain molten steel. The sulfur content in the molten steel is less than 0.02%, the phosphorus content is less than 0.02%, and the carbon content is 0.05%, silicon content 0.2%, manganese content 0.35%, nickel content 0.15%;
[0029] (2) Mold preparation: Prepare the casting samples, put the casting samples into the sand mold, process the sand mold through the mold processing table, bake the sand mold at a temperature of 600°C for 10 minutes, and then cool down to 350°C for standby;
[0030] (3) Pouring: pour the molten steel in (1) into the sand mold in (2), the pouring temperature is 1450°C, and the pouring time is 25s. After the pouring is completed, keep it warm for 20 minutes;
[0031] (4) Cooling: After cooling to room temperature, tak...
Embodiment 2
[0040] (1) Smelting: Melt the steel in an electric furnace. When the temperature rises to 1700°C, add a refining agent and refine for 20 minutes to obtain molten steel. The sulfur content in the molten steel is less than 0.02%, the phosphorus content is less than 0.02%, and the carbon content is 0.08%, silicon content 0.25%, manganese content 0.45%, nickel content 0.25%;
[0041] (2) Mold preparation: prepare casting samples, put the casting samples into the molding sand mold, process the sand mold through the mold processing table, bake the sand mold at a temperature of 700°C for 15 minutes, and then cool down to 380°C for standby;
[0042] (3) Pouring: pour the molten steel in (1) into the sand mold in (2), the pouring temperature is 1550°C, and the pouring time is 30s. After the pouring is completed, keep it warm for 25 minutes;
[0043] (4) Cooling: After cooling to room temperature, take out the formed casting, clean the surface, and get the casting after polishing.
