Tundish castable, namely tundish impervious castable, includes tundish impervious material, tundish lump-sum material and tundish knotted material. With the demand of society and the continuous improvement of steel quality, it is required that the less nonmetallic inclusions in molten steel, the better. Of course, the progress of continuous casting technology requires higher and higher service life of tundish working layer materials. Our factory now uses Huaheng's, the usage is 1, which is used to install impact plates, nozzles and nozzle seat bricks.
2. Spread the dry material evenly on the bottom of the tundish with a thickness of 80mm ... 3. Put the mold into the tundish with a crane. 4. Adjust the position of the mold to make the surrounding intervals consistent. 5, fill the dry material around the gap, about 40-50mm thick. 6. After filling, tap around the mold or use a vibrator (no more than 1 min) to confirm that there is no gap. 7. Bake according to the baking curve. Figure 108. Remove the mold. Install slag weirs and dams (or flow stabilizers). 9. You can go to the casting machine.
