[0019] Example 1: In figure 1 In the device, the equipment has a workbench 21 with a hole in the workbench 21, in which there are a pilot casting plate 23 and a pilot casting plate lifter 24, a water-cooled crystallizer 3 is connected to the workbench 21, and a water-cooled crystallizer 3 is installed outside The electromagnetic stirrer 20 is connected with a feeder 17 and a tundish on the upper part of the water-cooled crystallizer 3. The tundish includes a package body 9, a control valve 11, a launder 8 and a heater 30. There is a heater 30 outside the package body 9, a control valve 11 is connected to the package body 9, and a laundering trough is connected to the bottom of the package body 9. 8. The flow groove 8 communicates with the control valve 11. The water-cooled crystallizer 3 has a water tank. The center of the water tank has a straight cylindrical through hole. The bottom of the water tank is connected with a cooling water inlet 2 and the top is connected with a cool...

[0022] Example 3: In image 3 Among them, the water-cooled crystallizer may be a combined water-cooled crystallizer. The combined water-cooled crystallizer is composed of conductive water-cooled crystallizer 3a, non-conductive water-cooled crystallizer 35, high-temperature insulating pad 27, high-temperature resistant conductive ceramics, and non-metallic slow cooling jacket. Conductive water-cooled crystallizer The device 3a is located on the upper part of the non-conductive water-cooled crystallizer 35. A high-temperature resistant insulating pad 27 is connected between the conductive water-cooled crystallizer 3a and the non-conductive water-cooled crystallizer 35. The inner wall of the conductive water-cooled crystallizer 3a is coated with a layer of high-temperature resistant conductive ceramics. The upper part of the non-conductive water-cooled crystallizer 35 is equipped with a non-metal slow cooling jacket. A mandrel 14 is installed in the inner cavity of the combined water...
