When making steel casting components, we will find some shrinkage, which will cause high defect rate.
So how to reduce or avoid the shrinkage when lost wax casting process?
Firstly, we should ensure the uniform wall thickness, usually not less than 8mm.
Secondly, we should design the pouring temperature to around 1580°C. The temperature is higher, the molten steel’s fluidity is more better.
But if too high, it also can cause other casting defects.
By the way, the quartz sand is the best casting material under high temperature conditions.
Lastly, Baoding Guokun use the suitable design of riser, cold iron, iron supplement to ensure the solidification to prevent casting defects, such as shrinkages.
