一、引言在电解分离出来的阳极沉淀中,少量的非金属夹杂物与大量的碳化物混在一起,定量测定不稳定夹杂物MnO及MnS时,是在不破坏碳化物的情况下进行的,因而了解含锰碳化物对测定不稳定夹杂物的影响,并找出消除这种影响的方法,对准确测定钢中MnO同MnS的含量是密切相关的。A.M.萨马林在研究用硅锰合金预脱氧后指出,在脱氧过程中,当钢液中MnO,FeO的含量增高时,可使脱氧反应产物的熔点降低,流动性增高,从而使之易于上浮,相应地使成品钢中非金属夹杂物的数量减少。该文同时指出,钢中非金属夹杂物的含量与
I. INTRODUCTION In the anode precipitation separated by electrolysis, a small amount of non-metallic inclusions mixed with a large amount of carbides, quantitative determination of unstable inclusions MnO and MnS, is carried out without destroying the carbides, and thus Understanding the effect of manganese-containing carbides on the determination of unstable inclusions and finding ways to eliminate this effect are closely related to the accurate determination of the MnO content in the steel as well as the MnS content. After studying the preliminary deoxidation of Si-Mn alloy, AM Samarin pointed out that when the content of MnO and FeO in the molten steel increases during the deoxidation, the melting point of the deoxygenation reaction product will decrease and the fluidity will increase, making it easy to float , Correspondingly reducing the amount of non-metallic inclusions in the finished steel. The article also pointed out that the content of non-metallic inclusions in steel
