Processing of shrinkage defects in slag pot for steel castings

Steel casting manufacturers have been engaged in the production technology development and various research of large-scale steel castings for many years. In so many studies, Kunfeng cast steel has also overcome various difficulties in its development in order to provide customers with high-quality slag pots. In the communication with customers today, when it comes to forging, they are a little curious if the steel casting of slag pots adopts the forging process and there are shrinkage holes in the production. Steel casting manufacturers will come to introduce:

In the production of steel castings, the first thing is to ensure that the wall thickness is sufficient and uniform, usually not less than 8mm. Secondly, we should pay attention to the pouring temperature, generally about 1580 ℃. (quartz sand is a casting material used at high temperature) the higher the temperature, the better the fluidity of molten steel, which is more conducive to the forming of steel castings. However, if it is too high, it will also lead to defects of slag pot castings and increase the cost, which will do more harm than good. Riser, cold iron and iron supplement are the most commonly used methods in the casting process to ensure the solidification sequence of castings and prevent shrinkage defects.
