Abstract:
The operation of Blast Furnaces (BF) became even more challenging during the last years. Harsh conditions, like frequent stoppages and low production, poor raw material and a general uncertain outlook because of the need to reduce the carbon footprint make it difficult for operators to operate their BFs and to plan for the future.
In this context it’s quite important for operators to have proper information and feedback regarding the condition of their BF hearth refractory and the consequences of the operation on the BF hearth, but also with regard to the uncertain future to, to extend the service life as much as possible. Repairs, if required, are often reduced to a minimum and “smart” repair procedures are requested.
So called Multi-Point-Temperature-Sensor-Probes (MTP) help to monitor the condition of a BF hearth and sometimes help to extend the service life. They give precise feedback regarding the condition of the BF hearth, also with regard to the operation of the BF. Defects in the BF hearth refractory can be detected by these MTPs.
Re-profiling repairs allows to extend the service life of a BF, typically by several years, as long as accompanied by proper condition monitoring.
The following paper will illustrate the working principle of MTPs, will show typical applications and found refractory defects and will also provide an overview about possible and executed repairs on BF hearths.
