This section specifies the ethylene glycol diethyl ether diamine tetraacetic acid (EGTA) titration method for the determination of total calcium content in continuous casting mold slag. This section is applicable to the determination of the total calcium content (calculated as calcium oxide) in continuous casting mold slag. The determination range (mass fraction) is: 20.00% ~ 50.00%.
