First, classify and prioritize the equipment. Metallurgical equipment is diverse, and a one-size-fits-all approach to maintenance is inappropriate. First, classify the equipment according to its impact on production:
Critical Equipment: Equipment that directly determines production continuity, such as converters, blast furnaces, continuous casting machines, and core rolling mills, should have the highest priority and the most stringent maintenance schedules.
Important Equipment: Auxiliary equipment that supports core production processes, such as cooling systems, hydraulic systems, and oxygen supply systems, should have a lower priority and undergo regular maintenance.
General Equipment: Non-core auxiliary equipment, such as dust removal facilities and general lighting, should be maintained as needed.
After classification, review the original parameters, fault history, and operating conditions of each piece of equipment to provide a basis for subsequent schedule development.
Refine maintenance items and inspection standards.
Each maintenance item must have clearly defined content and acceptance standards to avoid ambiguous operations. For example, converter maintenance should clearly include: furnace lining inspection and patching, cooling system water pressure and flow monitoring, oxygen lance nozzle wear detection, and furnace tilting mechanism lubrication.
At the same time, the acceptance standards should be clearly defined: cooling water pipeline leakage rate not exceeding 0.1L/min, electrode connection point temperature not exceeding 120℃, to ensure that maintenance is feasible and acceptable.
