Pouring of large steel castings is not that simple. Not only should the amount of molten steel and the pouring speed be calculated before pouring, but also the pouring position of the casting should be determined. The pouring position refers to the position of the casting in the mold or whether one of its surfaces is above, below or on the side of the mold when pouring a large casting.
The selection of the pouring position of large steel castings also has principles.
First, the important part of large steel castings should be placed at the bottom as much as possible. The reason for this is to make the metal at the bottom of the casting solidify and be compensated under the static pressure of the upper metal, and the structure is dense;
Secondly, the important processing surface of the casting should face down or be upright. Because defects such as pores and non-metallic inclusions often appear on the upward surface of the casting.
Then, when individual processing surfaces must face upward, the processing allowance should be appropriately enlarged, and the large surface of the casting should face downward to avoid sand inclusions, etc.
In addition, it is necessary to ensure that large castings are fully poured, and the thin-walled parts are placed in the lower half or below the inner runner to avoid defects such as insufficient pouring and cold shut in large steel castings. Good castings need to be considered from many aspects to ensure their quality.
