B114钢锭是为生产60公斤/米重型钢轨而设计的,目前国内用于轧制钢轨等型管材的最大矩型钢锭。有关在包钢试生产B114钢锭取得的经济效益已在另文中阐述。本文总结钢锭及其制品的质量研究结果。通过对钢锭、钢坯、钢轨、化学成份、金相组织和纯净度等一系列研究表明:钢锭组织致密、结构正常,低倍偏析度不高于同类钢种的10吨矩型钢;轧制的60公斤/米钢轨质量符合国家标准的要求,这表明B114钢锭模设计所选用的各项技术参数能保证钢锭的质量。
B114 steel ingot is designed for the production of 60 kg / m heavy rail and is currently the largest rectangular steel ingot used for rolling rail and other pipe. The economic benefits obtained from trial production of B114 steel ingot in Baotou Steel Co., Ltd. are described separately. This article summarizes the quality of ingot and its products. A series of studies on ingot, billet, rail, chemical composition, microstructure and purity show that the ingot has compact structure and normal structure, and the low degree of segregation is not higher than the 10-ton rectangular steel of the same kind. The rolling 60 Kg / m rail quality in line with national standards, which indicates that the B114 ingot mold design of the various technical parameters used to ensure the quality of steel ingot.
