Abstract
The results of studying the effect of microcrystalline complex alloys with alkaline earth metals (AEM) on the quality indicators of 17G1S-U pipe steel have been considered. It has been shown that the treatment of steel with these alloys reduces both the maximum score of non-metallic inclusions (NI) and the mean level of contavmination for the main types of inclusions including corrosive-active ones (CANI). Alongside with this, fine calcium, strontium and barium oxysulfides with a reduced oxygen content are formed in the metal. The complex alloys with alkali-earth metals contribute to obtaining a more homogeneous and refined metal structure, an increase in the cold resistance and corrosion resistance of steel.

铸造管钢时微晶复合碱土金属合金的工业测试
摘要
考虑了研究含碱土金属微晶复合合金(AEM)对17G1S-U管钢质量指标的影响的结果。研究表明,用这些合金处理钢既可以降低非金属夹杂物的最高分数(NI),也可以降低包括腐蚀活性夹杂物(CANI)在内的主要夹杂物的平均污染水平。除此之外,在金属中还形成了氧含量降低的细钙,锶和氧硫化钡。具有碱土金属的复合合金有助于获得更均匀且更精细的金属结构,并提高钢的耐寒性和耐腐蚀性。
