METHOD AND SYSTEM FOR MONITORING WALLS OF A BLAST FURNACE

A method and a system for monitoring walls of a blast furnace are provided. The system includes plural temperature sensors and a process control system of the blast furnace. The blast furnace process control system is electrically connected to the temperature sensors, and configured to perform the method for monitoring walls of the blast furnace. The method for monitoring walls of the blast furnace includes: receiving plural furnace wall temperature data sets, in which the temperature data sets correspond to plural wall sections of the blast furnace in a one-to-one manner; calculating plural formed-block thickness values of the wall sections of the blast furnace in accordance with the furnace wall temperature data sets; determining if one of formed-block thickness values is greater than a predetermined thickness threshold value; calculating a sustained time period of the formed-block thickness value greater than the predetermined thickness threshold and determining if the sustained time period is greater than
