Nine factors of casting porosity formation and 5 improvement measures of process (2)

/in

1) The technological measures to prevent subcutaneous stomata mainly include: 2) Desulfurization treatment. The so-called desulphurization, that is, as far as possible, the sulfur in the molten iron is transferred to the slag, and then eliminated, the less FeS in the molten iron, the higher the desulphurization efficiency, appropriately increasing the basicity of the desulphurized […]
