母合金生产和定向凝固工艺 采用真空熔炼技术生产镍基高温合金母合金。可根据用户提出的不同规范如国家标准或其他国家标准进行研制生产,能做到最严格的纯净度和气体含量的控制,氧、氮含量分别可达15～20ppm。在工艺上采用计算机辅助控制,如对σ相及准确的化学成分控制等。近几年已向有关工厂提供多批次数量可观的优质母合金。 定向凝固工艺产品有实心与空心两种叶
Master alloy production and directional solidification process using vacuum melting technology production of nickel-base superalloy master alloy. According to different specifications proposed by the user such as national standards or other national standards for the development and production, to achieve the most stringent purity and gas content control, oxygen, nitrogen content up to 15 ~ 20ppm. In the process of using computer-aided control, such as the σ phase and accurate chemical composition control. In recent years, a number of batches of quality mother alloys have been provided to the factories in considerable quantities. Directional solidification process products are solid and hollow two leaves
