Embodiment Construction
[0024] In order to better understand the above technical solutions of the present invention, a further detailed description will be given below in conjunction with the drawings and embodiments.
[0025] see figure 1 , figure 2 Shown, strip continuous casting method of the present invention is realized by following steps:
[0026] A. Before pouring, open the argon and hydrogen valves, and control the ratio of argon and hydrogen according to the process requirements of different cast strip quality to generate mixed gas;
[0027] B. Enter the mixed gas into the molten pool formed by the rotating water-cooled crystallization 5 rollers through the gas introduction pipe 8, so that the mixed gas is filled with the airtight chamber 7;
[0028] C. At the beginning of pouring, the molten steel enters the molten pool filled with argon and hydrogen gas mixture from the ladle 1 through the long nozzle 2, the tundish 3 and the submerged nozzle 4, and the molten steel S is cooled by the w...
