构筑成形技术在φ15.4米不锈钢支承环锻件示范应用与评价数据集

以四代核电钠冷快堆φ15.4米不锈钢支承环锻件为研究对象，采用金属构筑成形技术，以316H不锈钢连铸坯为原材料，连铸坯通过等尺寸锯切、表面铣削加工、表面清洁处理、组坯堆垛、真空电子束封装等工序获得构筑封焊坯，构筑封焊坯加热至1200℃，通过锻造机进行镦粗、多向锻造、滚圆、冲孔、扩孔等工序获得环形锻坯，采用16m轧环机对其进行一体轧制成形，最终获得φ15.4m不锈钢支承环锻件，锻件热处理后进行机加工，并进行解剖评价测试。通过拉伸、冲击试验获得拉伸、冲击测试数据，利用光学显微镜、扫描电子显微镜获得全截面低倍组织照片。This dataset focuses on the ⌀15.4 m stainless steel support ring forging of the 4th-generation nuclear power sodium-cooled fast reactor, adopting the metal construction forming technology. 316H stainless steel continuous casting billets are used as the raw materials. The billets undergo equal-size sawing, surface milling, surface cleaning treatment, blank stacking, and vacuum electron beam encapsulation to produce the constructed and sealed billet. The sealed billet is heated to 1200 °C, then subjected to upsetting, multi-directional forging, round rolling, punching, and reaming via a forging press to obtain the annular forging billet. A 16-meter ring rolling mill is employed for integral rolling forming, ultimately yielding the target ⌀15.4 m stainless steel support ring forging. After heat treatment, the forging is machined, followed by dissection, evaluation and testing. Tensile and impact test data are collected through corresponding tensile and impact tests, while full-section macrostructure photographs are acquired using optical microscopy (OM) and scanning electron microscopy (SEM).
