Specifications

In the core is uses the high pressure to draw high density pure calcium wire

1. a evener each meter calcium  quantity and is higher, the stabler active calcium content to guarantee that the calcium processing effect is stabler;

 

 2. the thicker outside  shell (millimeter) and the high density pure calcium core rod may feed the calcium to the molten steel in a deeper spot, and pauses a longer time below the critical depth, thus achieves the higher calcium returns-ratio;

 

3.the pure calcium, the calcium treating processes will not lead the  powder package of core existence other oxide compounds to pollute the molten steel (for example: In calcium iron wire's ferric oxide as well as calcium aluminum wire aluminum oxide and so on);
