Resumo
From time-to-time ladle breakouts may occur, typically in the slag-zone. To prevent a ladle breakout, four infrared (IR) thermal cameras were installed in the ladle furnace station to prevent ladle refractory brick failure, thereby reducing maintenance costs and increasing operation safety. The system analyzes the temperature profile of the ladle shell during heating and is connected to the furnace’s programmable logic controller (PLC) and Inteco smart electrode controller (ISEC), its electrode regulation system. In the event of hot spot detection, the furnace automatically stops the heating and signals an alarm to the operator via the furnace PLC and human machine interface (HMI). Additionally, a four-screen monitor was installed, allowing the operator to monitor the temperature profile of the ladle furnace at any time.
