PREDICTION OF PREHEAT REFRACTORY TEMPERATURE PROFILE OF A LADLE FURNACE
The present disclosure addresses the technical problem of prediction of a preheat refractory temperature profile of a ladle furnace. Operational temperature of the ladle furnace, stability of sensors and placement make sensors not feasible. Computational Fluid Dynamics (CFD) simulations require large computation time and cannot be used for runtime applications in plants. The method and system of the present disclosure uses CFD modeling to carry out parametric study to generate data which is further processed to train an Artificial Neural Network (ANN) model that serves as a prediction model for predicting the preheat refractory temperature profile for at least a portion of the side refractory and at least a portion of the bottom refractory layer separately for which a new set of input data is obtained. The trained prediction model of the present disclosure provides a quick runtime prediction in plants.
Estimation or control of lengths and positions of one or more transversely localized electric current segments flowing between two conductive bodies
Magnetic field components are measured at multiple longitudinal positions and used to calculate estimated longitudinal position and length of a transversely localized electric current segment flowing across a gap between conductive bodies. The apparatus can be used with a remelting furnace. The electrode and ingot act as the conductive bodies, and arcs, discharges, or slag currents are the current segments spanning the gap. Actuators for movable sensors can be coupled to the sensors in a servomechanism arrangement to move the sensors along with the moving gap. An actuator for moving one of the conductive bodies can be coupled to sensors in a servomechanism arrangement to maintain the gap distance within a selected range as the gap moves.

METHOD FOR PLUGGING/UNPLUGGING PROBE OF METALLURGICAL AUTOMATIC THERMOMETER GUN
Disclosed in the present invention is a method for plugging/unplugging a probe of a metallurgical automatic sublance. A laser distance sensor is mounted on an end-effector of a drive device; the drive device drives the laser distance sensor to scan the automatic sublance according to setting areas; position and orientation information of the automatic sublance is calculated by a calculation unit; according to the position and orientation information of the automatic sublance, a gripper on the end-effector implements a process of plugging/unplugging the probe of the automatic sublance. According to the present invention, an existing automatic sublance does not need to be improved, and only external sensors need to be used for plugging/unplugging detection, so that the plugging/unplugging process can be accurately carried out.
