加食盐焙烧的石灰铁水脱硫实验研究

EXPERIMENTAL STUDY ON HOT METAL DESULPHURIZATION WITH LIME CALCINED WITH SALT

石灰的物性是影响其铁水脱硫能力的主要因素之一。在实验室条件下，通过对加食盐焙烧的石灰铁水脱硫试验研究，表明石灰的活性度并不完全对应其铁水脱硫能力；加食盐焙烧的石灰气孔率高、气孔尺寸大、气孔贯通率高，具有较高的铁水脱硫能力。

The physical properties of the lime are one of the important factors influencing efficiency of the lime in hot metal desulphurizationThe hot metal desulphurization with the lime calcined with salt has been investigated in laboratoryIt is shown that the lime activity is not directly correlated to desulphurization efficiencyThe lime calcined with salt has high porosity,large pore size and high penetration rate of pores,and therefore has higher desulphurization ability for hot metal
