在实验室对含硫非调质钢进行了冶炼和锻压实验，结果表明：随钢凝固速率的增加，钢中硫化物夹杂的尺寸减小而数量增多；随锻压压缩比的增加，硫化物夹杂碎裂而变得细小；在950 ℃锻压时硫化物的塑性最好，在1250 ℃时硫化物的塑性较好，在1050~1150 ℃之间硫化物的塑性较差；随着加热时保温时间的延长，硫化物夹杂的数量减少而尺寸增大。
Refining and forging experiments of non quenched and tempered steel containing sulphur were carried out in laboratory. The results showed that size of sulfide is decreased and amount of sulfide is increased with the rise of solidification rate of steel. The sulfide is broken to smaller pieces during forging with high compression ratio. The sulfide has best ductility at 950 ℃ and better ductility at 1250 ℃. However, the ductility of sulfide is worse in the range from 1050 ℃ to 1150 ℃.The amount of sulfide decreases and the size increases with prolongation of holding time.
