Temporary Repair Of A Large Axial Blast Furnace Motor-Blower As A Solution For A Steel Mill Operational Continuity.
Abstract
The repair work of a large axial blower that had its rotor and stator blades severely damaged is described. The 43 MW axial air blower is of critical importance for a large steel mill in Brazil, and the repair time was of the utmost importance. The circumstances in which the failure occurred, along with the investigation work for the causes, are also discussed. The failure of a second blower while the first one was under repair, which brought about a serious risk of loss of a blast furnace, and the measures taken to put it back to operation in a very short time, are also discussed. _ The purpose herein is to demonstrate the feasibility of reliable temporary repairs on mechanically damaged machines to reduce production loss in a very short time.
