三、脱磷脱硫技术过去传统的脱磷技术采用低温低碱度高氧化铁,自1975年以后,研究用苏打粉作脱磷剂,采用了低氧化铁高碱度的脱磷工艺,并发现可以同时脱硫,使处理后的铁水硫达到≤0.010%。目前实际操作采用两种系列的熔剂,即苏打系和石灰系,其中苏打系熔剂脱磷脱硫法主要有:①用苏打粉精炼法(简称 SARP法,即 Sada A sh Refining Process), Third, the dephosphorization desulfurization technology In the past, the traditional dephosphorization technology using low temperature and low alkalinity of high iron oxide, since 1975, the study of baking soda as a dephosphorization agent, using low iron oxide high alkalinity dephosphorization process and found It can desulfurize at the same time, make the treated hot metal reach ≤0.010%. At present, two series of fluxes are used in practice, namely, soda ash and lime. The soda ash flux dephosphorization desulfurization methods are mainly as follows: (1) Soda Ash Refining Process (SARP method)
