Calcium-based desulfurizers have the following characteristics compared to other desulfurizers: The price of calcium carbide-based molten iron pretreatment composite desulfurizers is expensive, requires corresponding equipment for use, is not suitable for storage, and is flammable and explosive, while the desulfurization effect is the same as that of calcium-based molten iron pretreatment desulfurizers. The price of magnesium-based molten iron pretreatment desulfurizers is 5-6 times that of calcium-based desulfurizers, requiring corresponding equipment and a certain level of technical knowledge for use. The desulfurization effect is slightly higher than that of calcium-based desulfurizers, but the production cost increases significantly.
It is recommended to use calcium-based desulfurization methods: Before the molten iron or steel is melted, place the desulfurizer at the bottom of the ladle, using the injection method, with a dosage of 1.5%-2.0% of the molten iron or steel, or add according to the actual situation of the customer, requiring the molten iron temperature to be above 1400 degrees, and then inject the molten iron or steel to achieve the desulfurization effect. This product is suitable for desulfurization in steel, iron, and alloys. The above are the characteristics of calcium-based desulfurizers, which everyone can refer to.
