早在1946年,已有文献报导,苏打灰(碳酸钠)能对铁水进行同时脱磷、脱硫予处理。但由于必须使用大量苏打灰才能取得效果,所以用苏打灰予处理铁水,未能得到推广和应用。因为当时还没有完善的喷吹技术和回收苏打灰的技术,而使苏打灰利用率不高所造成的。 目前,初步解决了苏打灰的喷吹技术和 As early as 1946, it has been reported in the literature that soda ash (sodium carbonate) can treat molten iron simultaneously with dephosphorization and desulfurization. However, since a large amount of soda ash must be used in order to achieve the desired effect, the use of soda ash for the treatment of hot metal has not been promoted and applied. Because at that time there was no perfect injection technology and the technology of recovering soda ash, but the utilization of soda ash was not high. At present, the initial solution to the soda ash injection technology and
