Calcium manganese aluminum liquid steel out-of-furnace refining agent and preparation method thereof

摘要: The invention discloses a calcium manganese aluminum liquid steel out-of-furnace refining agent and preparation method thereof. is composed of the raw materials, by weight, 34-36 parts oxide, 30-32 dioxide, 27-29 13-15 siliceous shale, 3-5 sodium carbonate, 7-9 modified tree ashes 9-11 light carbonate. carbonate are added in materials agent, waste turned into wealth, absorptive properties utilized fully, good desulfuration dephosphorization effect, phenomenon rephosphorization reduced, at same time, content oxide high, production cost reduced.
