1,desulfurization of molten steel, 2,refining furnace deep desulfurization, 3,reducing the cost of steelmaking.
Details:
desulfurization agent series products is a synthesis of new slag system, it not only can be used for hot metal pretreatment, desulfurization of molten steel, and is completely suitable for refining furnace ( or ultra clean steel smelting ) deep desulfurization. It has a slagging fast, good fluidity, high degree of purification, the desulfurization rate can reach more than 40-85%, the use of the product has the advantages of simple operation, stable quality, economic and efficient, greatly shorten the smelting time, it can achieve the purpose of desulfurization, and significantly reduce the cost of steelmaking
Two, the method of application and properties:
In 1, the package bottom to join, but to join in the steel flow impact position
In 2, with the flow of steel tapping, edge joining edge effect is better
In 3, the package bottom adding a part, the other part of the steel stream join
4, if the injection desulfurization according to the specific requirements of the operation
