Measures to prevent steel clamping at tundish nozzle



(1) Before installing the parts, clean up the sundries on the bottom plate of the parts, especially the cold steel, and install after checking that the parts and the bottom plate are correct.

Before installing the sizing nozzle, check that the board surface is smooth and free of cracks and damage. After installing the zirconium sizing nozzle, adjust the pressing device to ensure that the gap between the zirconium sizing nozzles is up to standard (the gap between the sizing nozzles is ≤ 0.3mm).

After the installation of the whole mechanism is completed, check the replacement operation to check whether the replacement process is smooth, and accurately measure the sliding stroke of the sizing nozzle to ensure the alignment of the upper and lower sizing nozzles.

(2) The converter provides qualified molten steel for continuous casting, reduces the number of times of changing the sizing nozzle in continuous casting, improves the skills of changing the sizing nozzle in continuous casting, and reduces abnormal erosion of the sizing nozzle caused by human operation. The foreign objects on the swing groove should be cleaned up.

These are all effective measures to avoid the phenomenon of steel clamping in the sizing nozzle in the production process.
