  • Device to separate water and solids of spray water in a continuous caster, and method to monitor and control corrosion background
    Patent number: 10722824
    Abstract: A system and methods are disclosed for treating cooling fluid in a continuous metal casting process having a spray chamber. In some embodiments, the system includes a first compartment with an intermittently operable outlet (e.g., valve) with an open state and a closed state, for removing particulate matter, and a second compartment that receives particle-free fluid from the first compartment. The first compartment may be tapered, conical, funnel, pyramidal shape or otherwise narrowed shape to facilitate settling of the particles. One or more sensors measure at least one property of the particle-free fluid to determine the opened or closed state of the outlet and to adjust chemical additives for the cooling fluid. In some embodiments, the system and methods reduce corrosion in spray chambers.
