摘要： A strip caster (10) for producing a continuous strip (24) includes a tundish (12) for containing a melt (14), a pair of horizontally disposed water cooled casting rolls (22) and devices (29) for electrostatically coating the outer peripheral chill surfaces (44) of the casting rolls with a powder flux material (56). The casting rolls are juxtaposed relative to one another for forming a pouting basin (18) for receiving the melt through a teeming tube (16) thereby establishing a meniscus (20) between the rolls for forming the strip. The melt is protected from the outside air by a non-oxidizing gas passed through a supply line (28) to a sealing chamber (26). A preferred flux is boron oxide having a melting point of about 550.degree. C. The flux coating enhances wetting of the steel melt to the casting roll and dissolves any metal oxide formed on the roll.

摘要： Casting molten metal using a segmented roll for casting continuous metal strip. A strip caster (10) for producing a continuous strip (18) includes a tundish for containing a melt and a pair of horizontally disposed water cooled composite casting rolls (84). The casting rolls are juxtaposed relative to one another for forming a pouring basin (16) for receiving molten metal. The composite rolls are formed from a plurality of annular segments (45). Each segment preferably includes at least a pair of coolant openings (34) and means for aligning the coolant openings, such as a pair of alignment openings (26). The segments are axially aligned and structurally connected by a pair of connecting rods (42) extending completely across the width of the roll through the alignment openings and through appropriate end plates (96). Each roll includes a load supporting spindle (86) with each end of the roll sealed by a rotary seal (88). Coolant water is supplied to the composite casting roll by a flexible conduit (90) and heated water is removed through a flexible conduit (92).
摘要翻译：使用分段轧制铸造熔融金属铸造连续金属带。用于生产连续条带（18）的带状连铸机（10）包括用于容纳熔体的中间包和一对水平设置的水冷复合铸辊（84）。铸辊相对于彼此并置形成用于接收熔融金属的倾倒盆（16）。复合辊由多个环形段（45）形成。每个段优选地包括至少一对冷却剂开口（34）和用于对准冷却剂开口的装置，例如一对对准开口（26）。这些段通过一对连接杆（42）轴向对准并且结构上连接，所述一对连接杆（42）通过对准开口和通过适当的端板（96）完全延伸穿过辊的宽度。每个辊包括负载支撑主轴（86），其中辊的每个端部通过旋转密封件（88）密封。通过柔性导管（90）向冷却水供应冷却水，加热的水通过柔性导管（92）去除。
