Zusammenfassung:	PURPOSE:To obtain a throat ring excellent in growth resistance, oxidation resistance, decarboxylation resistance, mechanical strength, thermal shock resistance, and heat resistance by using low-alloy cast iron with a specific composition as cast iron for the throat ring of an oxygen blowing converter for steelmaking. CONSTITUTION:The throat ring of an oxygen blowing converter for steelmaking is formed of a cast iron having a composition containing, by weight, 2.9-3.2% C, 1.45-1.6% Si,
