Audited Supplier Description:
Seamless calcium cored wire is a kind of cored wire used for steelmaking and used to replace traditional calcium silicon powder packets conductor. It consists of inner core and outer wrapping. Outer sheath is lapped by the band steel belt, the inner core materials include steel with solid core metal calcium and silicon powder. The bundle conductor used in steel liquid calcium treatment, at the same time to deal with the silicon powder, it also reduced the amount of ferrosilicon, increase the deoxidization effect, further improve the yield of calcium in liquid steel, steel and significantly reduce nitrogen absorption.
Seamless calcium cored wire
1) Calcium yield is high, increased by 50% compared with seamed metal calcium wire;
2) Calcium recovery is stable, small fluctuation between furnace time ;
3) Small fuming , good environmental protection effect ;
4) Good feeding depth, splashing is less than the conventional seamed pure calcium wire;
5) Low cost, calcium treatment cost is reduced by more than 10% .
6) Long shelf life, a year without inner Ca rod oxidation.
