Embodiment Construction

[0016] The present invention will be further described through embodiment now in conjunction with accompanying drawing. The cooling method of the present invention uses inert gas and water as the cooling medium, and around the outer circumference of the corresponding cooling section of the steel billet crystallized as the object to be cooled, the inner and outer multi-layer or evenly arranged spraying devices are arranged at a certain density, and the outer layer is sprayed to cover the corresponding The spraying method of spraying the inner layer of the steel billet is sprayed and cooled. The spraying pressure is 0.001-0.5Mpa, and under the same conditions, the spraying pressure is one-third to two-thirds of the pressure used in the existing cooling method. The spraying devices arranged around the corresponding cooling section for billet crystallization, or the spraying devices of each layer, are located on the same radial and / or axial line with each other, or are offset from...

Abstract

The invention discloses a billet steel crystallization secondary cooling method and a device, which have the advantages that the simplicity is realized, the implementation is easy, the composition is simple and reasonable, and the cooling effect is good. In the method, the multilayer covering spraying of gas-liquid mixing cooling media is carried out through a spraying device. The device comprises a spraying device in multilayer arrangement at the inner side and the outer side around the periphery of the billet steel crystallization cooling section, and the spraying device is respectively connected with an air supply source and a water supply source.

Description

technical field [0001] The invention relates to a secondary cooling method and device for steel slab crystallization in steelmaking and continuous casting. Background technique [0002] In steelmaking and continuous casting production, the casting speed depends on various relevant links in the continuous casting process. For example, the secondary cooling of the billet crystallization process is an extremely important link; at the same time, the quality of the billet in continuous casting production is also very important. It is largely affected by the secondary cooling process of the billet crystallization process. Therefore, the secondary cooling method and device for billet crystallization have a very important influence on the output and quality of billets. And the existing secondary cooling method all is to directly use water drench, and it is unsatisfactory no matter it is cooling effect, speed, uniformity of cooling, water consumption. Contents of the invention ...
