A 'bleeder valve' located in a blast furnace with a 105 foot tall chimney apparently released too much gas all of a sudden when the pressure built up.
While officials described it as "not unusual" locals ran out homes at the sound of what sounded like a blast and saw giant flames coming out.
Officials said there were no injuries to anyone. Nor any damage to machinery.
But finally the flames died down. Many locals said they couldn't remember seeing anything like this before.
The officials however said there was no need for any panic at any point of time.
