通过对沈阳重型机器厂30余年生产水轮发电机轮毂经验的总结、分析和研究,从铸造方法、工艺方案的选择、工艺参数的确定、造型材料、浇注系统的设计、冒口的设置、压铁的计算以及浇注、打箱、热处理等方面对轮毂工艺进行了论述,提出了可有效保证轮毂质量的铸造工艺方案。发电机轮毂是水力发电机组上的重要零件之一。由于它是红装在大轴上,在运动中工作,并承受重大的载荷(见图1),所以对其质量要求很高。铸件全部加工后,要经过超声波探伤,需达到厂标SZD002－81的Ⅱ级标准。但此件皮厚、件高,铸造中极易产
Through summarizing, analyzing and researching the wheel hub experiences of more than 30 years in Shenyang Heavy Machinery Plant, this paper analyzes the casting method, the selection of technological scheme, the determination of technological parameters, the design of casting material, pouring system, setting of riser Iron calculation and pouring, boxing, heat treatment and other aspects of the hub of the process were discussed and proposed to effectively ensure the quality of the wheel casting process. The generator hub is one of the most important parts on a hydroelectric generator. Because it is red mounted on a large shaft, working in motion and subject to significant loads (see Figure 1), its quality requirements are high. Casting all processed, to go through ultrasonic testing, to reach the factory standard SZD002-81 Ⅱ level. However, this piece of leather thick, high pieces, casting extremely easy to produce
