YJ105A牵引电机机座的铸造生产难点在于材质要求极高,无论是抗拉强度或是低温冲击韧性的要求,均超出了GB和ISO标准的规定。通过选用优质原材料、合理选择化学成分、严格的球化处理与孕育处理工艺以及热处理等措施,成功地实现了YJ105A电机机座国产化。研制结果表明,国产YJ105A牵引电机机座完全能替代进口产品。
YJ105A traction motor frame casting production difficulties is that the material requirements are extremely high, whether it is the tensile strength or low temperature impact toughness requirements are beyond the GB and ISO standards. Through the selection of high-quality raw materials, a reasonable choice of chemical composition, strict nodular processing and breeding process and heat treatment and other measures, successfully YJ105A motor base localization. Research results show that domestic YJ105A traction motor stand completely replace imported products.
