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.
