What Should Be Paid Attention To When Casting Alloy Steel Castings

1、 Temperature

Temperature has a great influence on the quality of castings, so a reasonable casting temperature range should be determined according to the alloy type, casting structure and mold characteristics. Select a reasonable casting temperature according to the model of carbon steel. Generally, the casting temperature is between 1540-1580 ℃, and the temperature of molten steel in the ladle.

2、 Speed

In terms of casting speed, under the condition of ensuring smooth gas discharge in the mold cavity, a higher casting speed can be used for castings requiring simultaneous solidification, and a lower casting speed can be used as far as possible for castings requiring sequential solidification.

3、 Operation requirements

Our company reminds you that the operation requirements must not be sloppy. Generally, the following two points should be observed:

1. When casting large and medium-sized alloy steel castings, the molten steel shall be placed in the ladle for 1-2min to be calm before casting.

2. After the casting is solidified, the press iron and box clamp shall be removed in time to reduce the shrinkage resistance of the casting and avoid cracks.
