滕州市宏天旋转接头厂生产的球体转动接头是应用于钢铁厂步进梁式加热炉化冷却系统新技术上的关键设备，它是将加热炉上做周期性运动的冷却构件与固定构件相连接的柔性管接上的主要部件上。在一定压力温度和流动介质条件下，实现与加热炉的活动装置的同步连续运动。经过多年的运行实践证明：该产品设计合理，转动灵活，密封可靠，受到了用户的高度评价，此项目埴补了国内空白，达到了同类产品的国际水平。The ball rotating joint is the key equipment applied to the new technology of walking beam furnace cooling system in iron and steel works. It is the main part of connecting the cooling component which moves periodically on the furnace with the flexible pipe which connects the fixed component. Under the condition of certain pressure, temperature and flowing medium, it can realize synchronous and continuous movement with the moving device of the heating furnace. After many years of operation practice, it has been proved that the product is reasonable in design, flexible in rotation and reliable in sealing. It has been highly praised by users. This project has filled the domestic blank and reached the international level of similar products.
