Furnace rebuild
Major capital event at the end of campaign life — refractory replacement, regenerator rebuild, electrical/control upgrade. Capital event of $20M–$60M+ depending on scale.
Hot repair
Repair work performed during operation (without cooling the furnace) — limited scope, used to extend campaign life.
