摘要： A steel ingot having a still-liquid portion therein is charged into a soaking pit; then, said ingot is heated by injecting a fuel from a combustion unit of said soaking pit into said soaking pit with a constant and minimum fuel flow rate capable of holding a pit temperature higher by from 10 to 100.degree. C than the cold point temperature of said ingot at the completion of solidification of said still-liquid portion in said ingot, until said still-liquid portion in said ingot is completely solidified; and then, upon the completion of said solidification, the surface portions of said ingot are further heated up to above a prescribed temperature permitting rolling thereof by injecting a fuel from said combustion unit into said soaking pit with a constant fuel flow rate of at least 60% of the maximum fuel flow rate of said combustion unit, thereby reducing the fuel consumption in said soaking pit.

摘要： In heating a material radiant at high temperatures, such as a steel product, in a heating furnace, the said material is charged into the heating furnace to heat. A discrimination mark is previously drawn on the surface of material to be discriminated on a portion readily watched from outside the furnace. A heat resisting paint sensitive to near ultraviolet rays is used to make the mark. The said material radiant-heated in the heating furnace is discriminated from outside the furnace as being radiant by applying near ultraviolet rays of a high pressure mercury lamp thereto from outside the furnace to provide a sharp contrast between the said material surface and the said discrimination mark for the discrimination of the said mark from outside the furnace.
