Problems solved by technology
Although this solution can greatly enhance the ultrasonic effect, the waveguide is directly inserted into the high-temperature molten steel. In particular, the material of the waveguide in this patent is graphite matrix, which is easy to pollute the molten steel and break easily under ultrasonic vibration. Once it occurs, it will directly affect the quality of the slab, and there will be bottlenecks in terms of reliability and long-term effectiveness
