Calcium is typically added to the melt one of three ways; by CaSi powder, CaSi wire, or calcium injection with argon. CaSi powder has the poorest recovery because calcium’s vapor temperature is lower than steel making temperatures (5). Therefore by simply throwing calcium powder on top of the melt, the majority of the calcium will vaporize
