Resumo

THE HOT STOVES OF A BLAST FURNACE ARE CORE TO THE OVERALL FURNACE OPERATION. THE PERFORMANCE OF THE STOVES HAS A DIRECT IMPACT ON THE HOT BLAST TEMPERATURE AND THEREFORE COST OF METAL PRODUCTION, AND THEIR FAILURE OR INABILITY TO OPERATE CAN BE EXTREMELY DAMAGING TO THE PROCESS STABILITY AND ECONOMIC PERFORMANCE OF THE FURNACE. WHILE IT IS OFTEN POSSIBLE TO PERFORM REPAIRS TO A HOT STOVE INDEPENDENT OF FURNACE SHUTDOWNS, THE STRATEGIES AVAILABLE TO DO THIS ARE OFTEN EXPENSIVE AND DISRUPTIVE TO PRODUCTION. IT IS THEREFORE VALUABLE TO EXTEND THE LIFE OF A HOT STOVE SO THAT MAJOR REPAIRS CAN COINCIDE WITH A FURNACE SHUTDOWN OR OTHER MORE CONVENIENT REPAIR TIME. HOWEVER, EXECUTING A FITNESS-FOR-SERVICE ASSESSMENT TO SAFELY EXTEND THE LIFE OF A HOT STOVE IS NOT TRIVIAL. IT REQUIRES AN INTENSE INTERDISCIPLINARY APPROACH AND SIGNIFICANT COLLABORATION BETWEEN THE OPERATING AND ENGINEERING TEAMS TO ENSURE THAT THE BUSINESS OBJECTIVES CAN BE MET THROUGH PRACTICAL, EFFECTIVE, AND MINIMAL INTERVENTIONS. WITH THE PROPER PLANNING, SPECIALIST ENGINEERING, AND COLLABORATION BETWEEN ALL STAKEHOLDERS, THE LIFE OF A HOT STOVE CAN BE MANAGED TO MEET THE OPERATOR’S NEEDS.
