Pure calcium, the calcium treatment process will not bring in other oxides existing in the powder cored wire and pollute the molten steel (such as iron oxide in the calcium iron wire and aluminum oxide in the calcium aluminum wire, etc.);

4. The thicker outer steel shell (mm) and high-density pure calcium core rod can feed calcium to the deeper part of the molten steel and stay below the critical depth for a longer time, thus achieving a higher calcium recovery rate;

5. High-density pure calcium core rod is easy to detect its quality and has a smaller specific surface area of ​​core wire, which makes it have a longer shelf life.
