Process Description

Previous practice of heating ladles with an open burner has been replaced by the use of covered ladle heaters. For a 100 ton ladle, reheating an in-use ladle to a 2100°F hot face temperature requires 3.3 MMBtu of natural (0.033 MMBtu/ton) with a heating time of under one hour. Holding this same 100 ton hot ladle at temperature requires 1.4 MMBtu/hour (0.0124 MMBtu/ton).
