Abstract: The low silicon high purity fluorite ball (80% -90% CaF₂ ≤8. 0% SiO₂) is developed by new fluorite ball process technology at Fogang Deyu Fluorite Bail Co. Due to high CaF2 content, low chalking ratio, damp-proof, increasing smelting slag speed to shorten steelmaking period, it is widely used in steelmaking of stainless steels. The results of refining stainless steel such as steel 304 (0Crl8Ni8) by 18 ~60 t AOD units show that as compared with common fluorite mine (75% CaF₂;）the consumption of fluorite ball decreases by 20% ~ 30%, the lime consumption decreases by 0 ~ 10% and the steelmaking time reduces 0 ~ 15 min.

摘要： 佛冈德宇萤石球有限公司研发的新型萤石球工艺技术生产的低硅高纯萤石球(80%～90%CaF₂、≤8.0%SiO₂),因CaF₂含量高、粉化率低、不易受潮,冶炼过程可提高化渣速度,缩短冶炼时间而广泛应用于不锈钢冶炼18～60 t AOD精炼304(0Cr18Ni8)等不锈钢表明萤石球消耗量较普通萤石矿(75%CaF2)降低20%～30%,石灰用量减少0～10%,冶炼时间缩短0～15 min。
