Dear All,
How the recovery of Ca in steel is related to the cleanliness of steel?
Higher is the % of formation of CaO, CaS, calcium aluminate in steel lower will be the recovery..then why steel industries are aiminig at higher Ca recovery %?
Is the Ca% in the slag is determined? if it is so then higher the Ca% in slag better is the performance of CaSi...please give your expert input
To set up the trial for CaSi cored wire insertion to produce clean steel (400 kg capacity) for R&d purpose, how to decide the free board, feeder station height, feeding rate to get maximum...
