Short Description:

The molybdenum (TZM) piercing mandrel is a critical component used in high temperature steelmaking processes. It is typically made of a molybdenum alloy (TZM alloy), which has excellent high-temperature strength and oxidation resistance. The piercing mandrel is mainly used in the blast furnace steelmaking process to blow oxygen into the furnace to promote oxidation and mixing of the steel. The high-temperature stability and corrosion resistance of molybdenum (TZM) piercing mandrels make them an essential component in the steelmaking process.
