| 摘 要： | 分别在模铸生产的Q420钢锭的冒口和本体顶部、中部、底部取样,以分析钢锭中非金属夹杂物的成分和分布。结果表明,钢锭中夹杂物指数在2.09~4.98个/mm2之间波动,本体中部的显微夹杂物含量小于其他位置。钢锭中的大型夹杂物总量介于5.7~22.5 mg/10 kg之间,其成分主要是SiO2和Al2O3,并含有少量的Na2O和K2O,主要来源于浇注用保护渣,钢锭本体底部的大型夹杂物远高于钢锭其他位置。 |

| Abstract: | For analyzing the composition and distribution of inclusion in the steel ingot,the experimental samples of the Q420 steel were sampled at the locations of the riser,the top of the ingot,the middle and bottom of the mold cast ingot.The result showed that the inclusion index was between 2.09 and 4.98(pron/mm2),the microscopic inclusions in the middle of ingot is less than other parts.The content of large inclusions in the ingot were between 5.7 and 22.5 mg/10 kg,which composed mainly by SiO2,Al2O3 and a littl... |
