Study of New Hot Metal Desulfurization Process on 1t Desulfurization Experiments

引用

Journal of Iron and Steel Research International 2011年第S2期18卷 125-128页

作者： REN Xiao-dong, zhang ting-an, DOU Zhi-he, LIU Yan, Lü Guo-zhi, HE Ji-cheng (School of Material and Metallurgy, Northeastern University, Shenyang 110004, Liaoning, China)

For the lack of the present hot metal desulfurization processes in iron and steel industry, our group has proposed the in-situ mechanical stirring method for external desulfurization of molten iron and researched this new method. This paper investigated this new in-situ mechanical stirring hot metal desulphurization process on desulphurization experiments of one-ton scale by using the new desulfurizer. The experimental results indicated that the desulfurization efficiency of in-situ mechanical stirring desulfurization process is 90% and the lowest sulfur content in the treated hot metal is 23ppm. By comparing with the methods of direct throwing desulfurizer and in-situ injecting desulfurization, in-situ mechanical stirring desulfurization process is the suitable desulfurizaton method.

在两种肥力条件下设置超高产栽培模式（SH）、高产高效栽培模式（HH）、农民习惯处理（FP）和不施肥对照处理（CK）4种栽培管理模式的定位试验,研究了以肥料投入为主要影响因素的不同栽培管理模式对黄淮海区域不同肥力农田耕层土壤团聚体组成及其碳、氮分布的影响,为通过培肥土壤实现小麦-玉米周年可持续增产增效提供技术支持.结果表明：与低肥力田块（LSF）相比,高肥力田块（HSF）耕层土壤团聚体的平均质量直径和几何平均直径高、分形维数低,有利于大团聚体的形成与稳定,各级团聚体的有机碳和全氮含量较高.优化施用氮磷钾肥、配施有机肥可增加耕层土壤团聚体的粒径、降低其分形维数,促进大团聚体的形成与稳定,对高肥力田块的影响大于低肥力田块;二者亦可提高有机碳和全氮在大团聚体中的含量与分布,其中,对〉5 mm团聚体的贡献率的影响在低肥力田块大于高肥力田块,对5～0.5 mm的各粒级团聚体的贡献率的影响在高肥力田块优于低肥力田块.
