[0019] Example 1:
[0020] A method for improving the success rate of quick change of continuous casting tundish includes the following steps:
[0021] Step 1: In the process of quick-change continuous casting tundish, the ladle is filled with molten steel and waits for 5-10 minutes, and the ladle reaches the continuous casting platform temperature of 1590-1600℃;
[0022] Step 2: The pulling speed of the molten steel in the working tundish is reduced by one gear every 20 seconds, and the pulling speed of the continuous caster is reduced to 0.3m / min within 8 minutes;
[0023] Step 3: Measure the liquid level of the working tundish. When the height of the working tundish is 400mm, drive the spare tundish to the heat exchange preparation area. When the working tundish stops pouring, connect the spare tundish to the working tundish that is pouring Move to the other side simultaneously;
[0024] Step 4: When the spare tundish is at the pouring position, quickly install the red hot immersion...
