过去硅铁粉末多用水泥粘结回用,用水泥作粘结剂,不仅工艺复杂,由于水泥是酸性材料,不利于控制铁水中的硫量。为克服上述缺点,我们用氧、氯化镁复合物(XMgCl_2·YMgO·ZH_2O)来粘结硅铁末。由于这些材料是碱性,有利于控制铁水中的硫量;同时还具有快干、快硬、强度高、吸 In the past, ferrosilicon powder was mostly used for cementing and cementing, and cement was used as a binder, which not only complicated the process but also detrimental to controlling the amount of sulfur in the molten iron because the cement was acidic. To overcome these shortcomings, we use oxygen, magnesium chloride complex (XMgCl_2 · YMgO · ZH_2O) to bond ferrosilicon. Because these materials are alkaline, is conducive to control the amount of sulfur in molten iron; also has fast-drying, fast hardening, high strength, suction
