Mobile crushers can also be called mobile crushing plants, mobile crushers, etc. It is an inevitable product of high-tech crushing technology in the new era, and its main features are that it can be operated mobilely, can walk freely, and is more convenient for transitions, ensuring that the equipment While the production is safe, the work process is more reliable.
·Longitudinal cracks are the typical surface defects of continuous casting slabs resulting in additional processing or even casting interruption Monitoring longitudinal crack defects is of great significance in stabilizing and improving the slab quality Herein a monitoring model is developed to recognize the longitudinal crack defect of continuous casting slabs
