Ladle Inner Nozzle
For steel plants, the service life of the ladle inner nozzle significantly impacts the lifespan of the ladle bottom, which in turn directly affects the overall ladle age. In light of the above, JISteel has successfully developed a long-life ladle upper nozzle using the latest matrix optimization technology and the most advanced dense packing theory. This product features excellent thermal shock stability, outstanding oxidation resistance, and strong erosion resistance.
