    摘要: A ladle preheater and method to remove moisture in the lining and set the bond in new refractory liners, to elevate the ladle temperature to that of the molten metal to be poured in order to cut-down on splatter, and to maintain the temperature in the ladle if it is not to be unloaded soon. Automatic drive means are provided for positioning the preheater over the ladle, comprising a refractory lined reflector provided with a gas-fired or oilfired heater supplied by external air circulated by an air blower. The ladle may be supported on its bottom or side for preheating.
