Abstract

The invention discloses an oxygen controlling system of metallurgical industry. The oxygen controlling system comprises a plurality of air compressors. The multiple air compressors are in parallel connection with a liquid oxygen storing tank through an oxygen pipeline. The output end of the liquid oxygen storing tank is connected with steelmaking equipment and provided with an oxygen pressure sensor. The oxygen pressure sensor is connected with a controlling system. The controlling system controls starting and stopping of the air compressors according to a detecting result of the oxygen pressure sensor. The oxygen controlling system of metallurgical industry has the advantages that automatic adjusting is achieved, energy consumption is saved, the oxygen bleeding rate is reduced, and energy source is saved.

Description

technical field [0001] The invention relates to the field of oxygen supply in steelmaking and ironmaking enterprises, in particular to an oxygen control system for the metallurgical industry. Background technique [0002] Oxygen is essential in the steel production process. Iron and steel plants are generally equipped with large-scale air separation equipment to produce oxygen to ensure supply. However, on the one hand, the oxygen production of air separation equipment is continuous, while the oxygen consumption in the steelmaking process fluctuates greatly. When the smelting rhythm of multiple steelmaking converters is fast, the oxygen consumption sometimes reaches 130% of the normal state, and when the converter is blowing or shuts down, the oxygen consumption is only 75% of the normal state. [0003] Therefore, the prior art cannot timely adjust the start and stop of the air separation plant according to the working conditions, and the inexhaustible oxygen must be relea...
