Desulfurizer used as desulfuration?in?iron?pre-treatment?.The effect of desulfuration in iron  pre-treatment is related to the steel quality.  2. Desulphurising in?molten?steel.  3. Totally suitable for the deep desulphurisation in secondary refining or Smelting superior pure steel.Features  1. Slagging fast, good liquidity,?high purification rate, desulfuration rate up to 40-85%.  2. Easy to use,stable working performance,economical and effective.  3. Greatly shorten the smelting time,?not only get the purpose of the desulfurization,also lower the casting cost.Direction  1. Pre-add to the bottom of ladle at the steel impact place.  2. Then add along with molten steel flow, adding while tapping is better.  3. Pre-add a part below the ladle and add another part along with the flow.SpecificationChemical CompositionFD-TL-1FD-TL-2FD-TL-3Ca O (%)50-6045-85>70SiO2（%）< 103-7< 8Al2O3 %10-158-1210-20Na2O(%)--15-20--Si Ba (alloy %)----3-8Moisture（%）≤0.5≤0.5≤0.5Grain size（mm）1-31-31-3Melting point ℃1300 +/-501200 +/-501300 +/-50ContactTopchase promise：We guarantee the physicochemical indexes and performance meet your requirement,before quote you the price,we will be appreciated if you can provide the information below:1.
