一种具有国际先进水平的转包法球化处理设备及工艺技术研制成功,并在中国第一拖拉机工程机械公司球铁分厂投入生产使用。该项技术的特点是以纯镁作为球化剂,使用专用球化转包,球化剂加入量少,吸收率高,处理过程中铁水温度降低小,处理时间短、球化质量高,并且可处理含硫量高的原铁水,终硅量可根据需要进行调整。生产过程简便安全,生产效率高。这种新工艺与目前各地普遍使用的冲入法球化处理工艺相比,每吨铁水球化处理成本降低约50元。
An internationally advanced subcontracting ball processing equipment and technology developed successfully, and in China’s first tractor construction machinery company ductile iron factory put into production use. The technology is characterized by pure magnesium as a nodulizer, the use of special ball subcontracting, nodulizing agent added less, high absorption rate, the process of reducing the temperature of the molten iron is small, the treatment time is short, high quality ball and can be Treatment of high sulfur content of the original hot metal, the amount of silicon can be adjusted as needed. The production process is simple and safe, high production efficiency. This new process is widely used around the current law into the ball compared to the ball per ton of iron ball water treatment costs reduced by about 50 yuan.
