Description

Technical Field

[0001] The utility model belongs to the technical field of metallurgical equipment and relates to an oxygen determination device in a converter. Background Art

[0002] For large converters, auxiliary lances can be used to accurately determine oxygen, carbon and temperature. However, for small converters, due to the small furnace mouth, it is impossible to arrange the insertion position of the oxygen lance and the auxiliary lance at the same time, and oxygen determination still needs to be done manually. However, during manual operation, the insertion depth of the oxygen lance to the molten steel surface cannot be accurately controlled, especially when the slag is too sticky or too thin, the insertion depth is more difficult to control, resulting in large deviations in the results of oxygen determination in the converter, misleading the amount of deoxidation alloy added, and bringing difficulties to the subsequent process. In addition, when oxygen determination is done manually, the operator works at a close distance to the furnace mouth. Once slag splashes, it is easy to cause personal injury accidents to the operator. Utility Model Content
