Abstract

1305466 Sintered desulphurizing flux KAWASAKI SEITETSU KK 21 Oct 1970 [24 Oct 1969 24 Sept 1970 (2)] 50044/70 Headings C7D and C7M A sintered flux for desulphurizing molten pig iron comprises in parts by weight 100 CaO and 3-50 total of at least one of the following (a) up to 30 CaF 2 , NaF, MgF 2 , BaF 2 and Na 2 SiF 6 and (b) up to 40 Na 2 CO 3 or an equivalent amount of NaOH and Na 2 O. The particles <0À3 mm diameter are mixed optionally with NaH 2 PO 4 , CaCl 2 , starch or clay as a binder, sintered at 800-1600‹C and crushed to -4 mm size. The CaO may be replaced by CaCO 3 or Ca(OH) 2 .
