据“Steelmaking Conference Proceedings”1987;70报道,中间包钢中总氧含量是夹杂物含量的一个重要指标。钢包到中间包注流的保护可减少中间包O_2含量,从70PPm降到17PPm。通过使用中间包作为夹杂分离装置,可进一步减少中间包夹杂含量。
According to Steelmaking Conference Proceedings 1987; 70, total oxygen in tundish steel is an important indicator of inclusion content. The protection of ladle to tundish injection can reduce the content of O_2 in tundish from 70PPm to 17PPm. By using the tundish as the inclusion separation device, tundish inclusion can be further reduced.
