1. Pouring tools, inoculants for furnace pretreatment, modularizing agents, etc. must be fully dried before use and can be used after drying.
2 The pouring personnel must wear work clothes and protective glasses as required, and the workplace should be unobstructed. The molten metal in the ladle should not be overfilled, so as not to overflow and hurt people during transportation and pouring.
3. Correctly choose the pouring speed, that is, pour slowly at the beginning to facilitate the alignment of the gate, reduce the impact of the molten metal on the sand mold and facilitate the discharge of gas; then pour quickly to prevent cold isolation; pour slowly before it is full, that is Follow the slow, fast, slow principle.
4. For castings with relatively large liquid shrinkage and solidification shrinkage, such as medium and large steel castings, they should be poured from the gate or riser in time after pouring.
