【摘要】 为向炼钢提供优质低硫铁水，针对目前中小型高炉和化铁炉生产低温、高硫铁水的生产实际，研制低熔点、低粘度自动流渣的高效炉外铁水复合脱硫剂。经安钢试用，脱硫率达到约50％，且对铁水温降，磷、硅含量等无不良影响。更多还原

【Abstract】 As it is very common that hot metal has higher sulphur content under nounal working condition in cupola furnace and middle or mini blast furnace, one kind of new compound desulphurizer with the characteristics of lower melting -- point, lower viscosity and free -- flowing has beensuccessfully developed. Through practice in Anyrang Iron & Steel Co., it is shown that desulphurization rate can get up to 50%, and this desulphurizer has no bad effect on temperature drop of hotmetal and content of phosphorus and silicon.更多还原
