To research the desulfuration characteristics of calcium-based sulphur-fixing agent and decomposing-rate of desulphur object CaSO4 systemically under different conditions, and analyzed its desulfuration mechanism .

为了探求煤燃烧过程中传统钙基固硫剂固硫率低下的原因，本实验选用有代表性的含硫为2.92％的国家标准煤样，在不同条件下系统的研究了钙基固硫剂的固硫特性和固硫产物CaSO4的分解率；并分析了其固硫机理。

The author analyzed total oxygen content, nitrogen content in steel made by typical process and the inclusion composition, change rule, morphology and distribution qualitatively and quantitatively by image analyzer, big sample electrolysis, SEM and energy spectrum analysis. The results showed that final inclusion form was small granule MnS, calcium aluminate, a small quantity of silicate and lumpy Al2O3. By intensifying deoxidation alloying process control in converter, argon blowing and slagging control and desulphuration and calcium reduction operation in refining course and overall-protection casting, the oxygen content was reduced by 20% above averagely, nitrogen content was reduced by about 10% and the inclusion content was reduced by 30%.

通过全O、N分析，夹杂物图像分析仪、大样电解、扫描电镜及能谱分析，定性和定量分析了典型工艺钢种钢中全O、N含量和工序过程夹杂物的构成、变化规律及形态、分布，分析钢中最终夹杂物表现形式主要为小颗粒的MnS、铝酸钙、少量的硅酸盐和块状Al2O3，通过强化转炉脱氧合金化工艺控制、精炼过程吹氩与造渣控制及脱硫和钙处理操作、全程保护浇注，钢水中O含量平均降低20％以上，N含量降低10％左右，铸坯中夹杂物含量降低了30％。
