WebBasic oxygen furnace (BOF) or basic oxygen process (BOP) is a method of primary steelmaking in which carbon-rich molten pig iron is made into steel. In BOP steelmaking, molten iron from a blast furnace is charged into a refractory-lined furnace, and then oxygen is injected into molten iron at high speeds, resulting in oxidation of carbon and ... Webmolten state ready for charging the BOF converters for up to 22 hrs. The refractory linings in the torpedo ladles have to be replaced periodically. Previously, the lining life was 1100 – 1200 cycles after carrying 300 to 350kt of iron. This required critical transport capacity to be removed from the process flow during relining.
