YL-3 filler sand used in steel making

Suitable for steel making of LF furnace and RH furnace . The time of molten steel in ladle are between 1 to 2.5 hours.
 the production of chromium chrome sand is the quality of South Africa's imports of high-quality chrome ore-based materials, by adding the right amount of lubricant, to help sintering agent, reducing agent, such as combined system, as the bottom of the ladle filling material, a The requirements in the lower temperature sintering, in addition, due to the proportion of chromium sand, you can effectively avoid the addition of molten steel floating sand caused by floating accident
