Pure Ca Rod
Calcium (atomic symbol: Ca) is a reactive, soft metal. Its application in steel industry had been started since 1970’s. Development to introduce Ca into molten steel had been starting from Ca lump addition, to lance injection of Ca powder, and now the cored wires.
Steel making temperature generally at approximately 1600˚C, Al2O3 with melting point as high as 2050˚C will present in molten steel as solid inclusion. With increasing of Ca%, melting point of the calcium-aluminate complex oxides will gradually reduce.
Thanks to continuous technical improvement. Almat Asia develops an innovative product Seamless Pure Ca Rod that allows very high repeatable Ca recovery and cost effective.
