Parameter table of High Pressure Equal Elbow

What’s malleable cast iron ?

Malleable cast iron is produced from white cast iron, which is made from hot liquid iron with certain chemical components. The white cast iron needs to be treated by malleablizing, such as graphitizing or oxidation and decarbonization, then its metallographic structures or chemical components will be changed, so can become into malleable cast iron.

Reference list of High Pressure Equal Elbow

Three major producing process of malleable cast iron

Rough casting:

1. Blast furnace smelting
2. Electric furnace adjustment
3. Sand Mixing or Core shooting core
4. Automatic modeling or Semi-automatic modeling
5. Casting
6. Broken box
7. Sorting code
8. Rough casting

During casting , we need to check the sample is made by molten iron , Spectral test and artificial test of the composition test . We will test the temperature after every pack of molten iron baked and before casting.
