The utility model belongs to advancement of a temperature measuring/sampling device structure of a steelmaking revolving furnace, in particular to a composite temperature measuring/sampling device of a revolving furnace. The device comprises a temperature measuring gun. A temperature measuring head is arranged on the front end of the temperature measuring gun. A sampling head is fixedly connected to a temperature measuring gun rod arranged at the back of the temperature sensing head via a connecting seat. The device is proper in structure, convenient to use and practical; temperature measurement and sampling work when the steelmaking revolving furnace is turned down can be simultaneously finished; operators can be reduced; labor intensity of the operators is reduced; time for turning down the furnace is saved; and smelting period is shortened.
