    摘要： This invention relates to the production of refractory linings. According to the method, the lining formed by refractory materials is heated to a temperature sufficient to cause the sintering of the materials on at least an internal surface of the said lining. To provide this heating action, a flame is produced from a fuel gas and oxygen, within a partially closed volume close to the lining which is to be sintered, and a diluting gas is injected between the flame and the lining, at least during the first part of the rise in temperature. The method is applicable to the sintering of the linings of vessels utilized in metallurgy, in particular of induction furnaces.

    摘要： A preheater for uniformly heating the refractory lining of a ladle, ingot mold or the like. A concave, refractory lined cover is provided with one or more flues for exhausting noxious fumes and products of combustion. There is also provided an axially extending burner for projecting a flame onto the walls of the ladle refractory lining. Fluid operated means are provided for vertically tilting the boom which pivotally supports the ladle cover to enable the cover to be laid, with a tight fit, on the mouth portion of the ladle, - also to enable lifting of the cover and lateral swinging thereof from the closed position. A modification, particularly suitable for large ladles, is to provide a plurality of burners which emit flames substantially tangentially inwardly of the cover to uniformly heat the ladle lining.

    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.
