摘要： A rotary hearth finish annealing furnace includes coil tables carrying thereon steel plate coils to be annealed with their axes being vertical, a hearth traveling along a circle having a predetermined radius and supporting thereabove the coil tables, inner covers covering the coils on the coil tables, and a protective cover covering the above members over a predetermined distance.According to the invention, heating means for heating the coils are arranged at a level above upper ends of the steel plate coils. In a preferred embodiment, the coil tables are arranged so as to permit the coils to be arranged thereon in at least two circular rows on a single plane concentric to said traveling circle of the hearth. Moreover, portions of the hearth subjected to loads of the coils and coil tables are made of comparatively high strength bricks and the other portions are made of a light weight refractory material. With these arrangement, the furnace according to the invention operates with a high thermal efficiency to greatly save the energy required for its operation.
摘要翻译：一种旋转炉床终轧退火炉，其特征在于，具有：钢板线圈，其垂直轴线退火的线圈台，具有规定半径的圆形的炉床，在所述线圈台的上方支撑，覆盖所述线圈台的线圈的内罩，以及在预定距离上覆盖上述构件的保护罩。根据本发明，用于加热线圈的加热装置布置在钢板卷材的上端的上方。在优选实施例中，线圈台布置成允许线圈在与炉床的行进圆同心的单个平面上以至少两个圆形排布置在其上。此外，炉膛承受线圈和线圈台的负荷的部分由较高强度的砖制成，其他部分由重量轻的耐火材料制成。利用这些布置，根据本发明的炉以高热效率运行，以大大节省其运行所需的能量。
