Secondary cooling steam white eliminating device for continuous casting

Abstract

The invention discloses a secondary cooling steam white eliminating device for continuous casting. The device comprises a water supply pipe module, and multiple high-pressure nozzles communicating with the water supply pipe module; the high-pressure nozzles are mounted on the inner side wall of a continuous casting workshop steam discharge main pipe; a drainage port communicating with a water circulating system is formed in the bottom of the inner side of the steam discharge main pipe; high-temperature steam in a continuous casting workshop is sucked into the steam discharge main pipe, and iscontacted with water sprayed by the high-pressure nozzles for condensation as water drops; and the water drops flow into a water outlet along with the inner wall of the steam discharge main pipe to enter the water circulating system. The device has the following beneficial effects: the device improves the white eliminating effect and efficiency, is simple and reasonable in equipment, needs no large condensation equipment, heating equipment and other energy to reduce the equipment investment cost and operation cost, and is mounted by dint of the steam discharge main pipe to achieve easy operation.

Description

technical field [0001] The invention relates to the technical field of metallurgy, in particular to a secondary cooling steam whitening device for continuous casting. Background technique [0002] In the continuous casting process of iron and steel production process, a large amount of water vapor will be generated when the casting slab is cooled in the secondary cooling room, and the fan is generally used to discharge it directly through the air duct; the steam discharged outside will generate water vapor when it is cooled and released, and the water vapor cannot be completely absorbed by the atmosphere. Absorption, it will drop below the dew point to produce condensed water, forming a "white mist" phenomenon. The white mist floats on the roof and surrounding walls of the factory building. Long-term operation causes the color tiles on the roof and walls to corrode, and the direct discharge of white mist has a certain impact on the surrounding living environment and the comp...
