摘　　要：30tH型中间包感应加热装置用于轴承钢、帘线钢、汽车用钢和石油钻具用钢等钢种的370 mm×490mm铸坯的生产.叙述了中间包感应加热原理、设备构成、砌筑和加热档位控制.生产应用结果表明,使用中间包感应加热可明显改善夹杂物控制水平,降低夹杂物指数,钢水过热度从使用前的17～38℃降至8～ 25℃;钢水实际过热度与目标过热度的差值为±3 ℃.The 30 t H type tundish Induction heating device is used for production of 370 mm × 490 mm casting bloom of steel grades including bearing steel, steel for tyre cord wire, steel for auto and steel for oil drill tool. The tundish heating principle, equipment structure, masonry technology and heating rating control are presented. Production application results show that the tundish induction heating technology application is available to obviously improve inclusion control level and decrease inclusion index; the superheating extent of liquid decreases from original no-using induction heating technology- 17 38 ℃ to 8 - 25 ℃ ; the difference between liquid measured superheating extent and aim superheating extent is ±5 ℃.
