Embodiment 1
[0046] Such as figure 1 As shown, a device for rapid decarburization steelmaking by segmental temperature control and adjustment of gas flow rate, said device has a molten iron tundish 1, a twin-roll casting mill 2, a high-temperature molten iron 3, a nip roll 4, a thin slab 5, a back-up roll 6, It consists of an electromagnetic vacuum temperature control device 7 , a solid decarburization steelmaking chamber 8 , an atmosphere control nozzle 9 and a flue gas analysis system 10 . The molten iron tundish 1 is above the twin-roll casting machine 2, and the twin-roll casting machine 2 is equipped with a plurality of nip rolls 4 correspondingly. The chamber 8 passes through and runs through the entire solid decarburization steelmaking chamber 8 until the outdoor is connected with the conveying device. The solid decarburization steelmaking chamber 8 is a continuous decarburization device. An electromagnetic vacuum temperature control device 7 is installed at the entrance, and an at...
