 At 7 : 45 am local time , the ladle in question separated from the overhead iron rail that connected it to the blast furnace while it was being positioned over a <unk> in preparation to pour out its contents . All 30 tons of liquid steel , which was at a temperature of approximately 1 @,@ 500 degrees Celsius ( 2 @,@ 730 F ) , was spilt . This liquid steel then burst through the windows and door of an adjoining room five meters away where workers had gathered during a change of shifts , engulfing that room entirely .
