    • Improving the Reliability of Blast Furnace Blowpipes

      In early 2010, a continuous improvement team at AK Steel Corp. – Dearborn Works was assembled to develop a road map for improving blowpipe reliability. The team adopted a practical engineering approach that involved working the four cornerstones of a reliability cycle. Key stages within the ongoing reliability program are detailed. Results to date are discussed in addition to future innovations that could further improve blowpipe reliability.

    • Understanding the Fire-Resistant Hydraulic Fluid Selection Puzzle

      This paper deals with choosing the correct product type to maximize equipment efficiency and still stay within budgetary constraints. Discussed are the advantages and disadvantages of each of the most popular fire-resistant hydraulic fluid types on the market today. Most suppliers have an arsenal of fire-resistant products, so it is important to understand the limits of each type of fluid and how it could affect operations.

    • Effective Use of Condition Monitoring in Tracking Large Gearbox Bearings

      Main drive gearboxes are found in both hot strip mills and cold strip mills, and their failure can bring an entire step of the steelmaking process to a standstill. Condition monitoring of bearings can provide invaluable information as to the distresses they may be seeing. Coupling this vibration data with in-place bearing inspections can help to improve overall reliability of the equipment. Subsequent thorough examination of the bearings can allow for corrections to extend the life and reliability of the newly installed equipment.

    • Blast Furnace Casthouse Refractory Maintenance Optimization

      This paper discusses recent developments to optimize blast furnace casthouse refractory performance by way of a unique refractory technology that provides enhanced performance in blast furnace iron/slag contact applications. Modular working lining shapes extend initial refractory life while providing a foundation for periodic maintenance. The resulting benefits include reductions in refractory consumption and increased availability.
