在航空技术中,采用长尺寸厚板的大型整体结构,尤其需要2米宽的长厚板。为了解决这个课题,最初铸造了截面为400×2140毫米B95和B95的铸锭,其化学成分如表1所示。合金在感应炉和电炉中进行熔炼,用半连续方法,以40~45毫米/分的速度进行浇注。静置炉中的金属温度不超过700℃,流槽中的金属温度不超过672℃。通过含钛的吸气剂,和装有液体熔剂的装置精炼金属和并用筛孔为0.6和0.4毫米的二层玻璃丝网
In aeronautical technology, a large, monolithic structure with long planks is used, in particular a 2-meter wide plank. In order to solve this problem, an ingot having a section of 400 × 2140 mm B95 and B95 was originally cast, and its chemical composition is shown in Table 1. The alloy is melted in an induction furnace and an electric furnace, and is cast in a semi-continuous manner at a rate of 40 to 45 mm / min. The temperature of the metal in the stand furnace does not exceed 700 ° C and the temperature of the metal in the bath does not exceed 672 ° C. A titanium mesh-containing getter and a device equipped with a liquid flux were used to refine the metal and to use two layers of glass gauze with mesh openings of 0.6 and 0.4 mm
