日本神户钢铁公司加古川钢厂的3号板坯连铸机,为了提高连铸板坯的质量,而在连铸机的二次冷却区应用了一种辊内的电磁搅拌装置。在双流连铸机的每个铸流上共设置4对电磁搅拌辊,可对应于铸速选用3对或4对搅拌辊进行搅拌。该板坯连铸机所浇铸的板坯的尺寸为230×960～1770mm。所用的电磁搅拌辊的技术规格为:最大搅拌功率分别为52kW(1,2对辊)、71kW(3,4对辊),最大电流分别为365A(1,2对辊)、400A(3,4对辊),电磁搅拌辊的辊径分别为250mm(1,2对辊)、305mm(3,4对辊)。
No.3 slab caster at Kakogawa Steel Works, Kobe Steel, Japan, used a roller-type electromagnetic stirrer in the secondary cooling zone of the continuous casting machine in order to improve the quality of continuous casting slabs. A total of 4 pairs of electromagnetic stirring rollers are arranged on each casting strand of the twin-strand caster, and three pairs or four pairs of stirring rollers can be used for stirring corresponding to the casting speed. The size of the slab cast by the slab caster is 230 × 960 ~ 1770mm. The technical specifications of the electromagnetic stirring roller used are as follows: the maximum stirring power is 52kW (1, 2 pairs of rollers) and 71kW (3, 4 pairs of rollers) respectively, the maximum current is 365A 4 pairs of rollers). The diameters of the electromagnetic stirring rollers are 250 mm (1, 2 pairs of rollers) and 305 mm (3, 4 pairs of rollers), respectively.
