DEVELOPMENT OF DESULPHURIZER FOR RH VACUUM TREATMENT OF MOLTEN STEEL

实验室真空条件下进行的钢液脱硫试验表明，CaO－CaF2渣系脱硫剂脱硫能力强于CaO－CaF2－Al2O3渣系。同时，预熔型脱硫剂具有脱硫率高、脱硫率稳定、防潮性好、对耐材侵蚀相对较低的特点。

The experiment for desulphurization of molten steel under vacuum condition was carried out in 10?kg vacuum furnace.The results obtained show that the desulphurising capbility of CaO-CaF2 system is better than that of CaO-CaF2-Al2O3 system.The pre-melted desulphurizer is characterized by higher and stable desulphurising percentage,good moistureproof ability and less erosion of the refractory.
