Description
Technical field
The present invention relates to a device that is used to regulate the secondary cooling; The cooling of this secondary has the through-flow pipe network of the agent that is cooled of continuous casting installation for casting, and this continuous casting installation for casting adapts to various casting tasks, especially aspect the steel grade and adapt to during casting cycle, producing of task especially.
Background technology
When continuous casting steel, realize solidifying and realizing the secondary cooling at the strand-guiding roller position through the elementary cooling of steel in casting mold.Directly be sprayed onto on the strand shell at the position of exposing between the continuous casting billet guide roller under the pressure in strand-guiding roller internal water or water-air mixture, from strand, removing heat thus.
Adjustable range that need be big in the secondary cooling in new continuous casting installation for casting owing to a large amount of product serials; The LC steel owing to can cast apace on the one hand; Wherein need pay a large amount of water; In pearlitic steel and tubulation steel, can also wherein only adjust very little cooling water inflow with enough temperature aligning steel billets on the other hand in the aligning scope.
This task is achieved through the bi-component cooling system with water-air nozzle, and they have big adjustable range, for example 1:14.And with the one-component nozzle that water conservancy project is done only have the adjustable range of 1:4 and therefore for many continuous casting installation for casting since above-mentioned requirement can only be suitable for limitedly.
Need for example can not crack thus in strand width adjusted even temperature as far as possible in addition owing to too cold steel billet seamed edge in the aligning scope.This problem is able to solve through the inlet zone of independent regulation, and they cover different casting width.Need regulating loop individually at this for each width district.
When continuous casting, realize the secondary cooling at present thus, the guiding mechanism of secondary cooling is positioned at beyond the segmentation of water distributor chamber.Can adjust the water yield of regulating loop through automatically controlled valve.Utilize flow measurement regulating section at this with the interior water yield that is used for regulating loop of trying to achieve reality.The water yield of regulating by regulating loop utilize the water clamping plate of segmentation to be given in the segmentation and there through pipeline and nozzle ejection to billet surface.Seal member on clamping plate is responsible for, and the coupling of sealing cooling agent joins when segmentation is installed.
