Description

Technical Field

[0001] The utility model belongs to the technical field of continuous casting equipment, and more specifically, it relates to a crystallizer cooling system for continuous casting equipment. Background Art

[0002] At present, in domestic industrial production, common casting technologies mainly include direct chill casting, hot top casting, gas slip casting, electromagnetic casting, etc. Among them, hot top casting is the most widely used in large-scale casting due to its good ingot quality, simple operation and maintenance, etc. The crystallizer is the most critical component in continuous casting equipment and is the heart of the continuous casting machine. The performance of the crystallizer plays a crucial role in improving the continuous casting productivity, maintaining the normal production of the continuous casting process, and ensuring the quality of the cast billet.

[0003] The cooling system of the crystallizer in the existing technology group red is a combined structure, which is composed of multiple metal plate parts (such as copper plates) combined into the required cooling cavity (inner cavity). Cooling water passes through the inner cavity to achieve problem control to reliably cool the product. Both the inlet and outlet water of this kind of crystallizer have only a single pipeline, with poor cooling uniformity, difficult maintenance, and easy water seepage in the cooling cavity.

The crystallizer cooling system for horizontal continuous casting described in the utility model cools the circulating water before entering the crystallizer through the heat exchange mechanism when the water temperature in the inlet pipe cannot meet the cooling requirements by arranging the heat exchange mechanism in parallel on the inlet pipe, ensuring the smoothness of production, and the inner sleeve of the crystallizer is provided with a concave reduced diameter section, ensuring that the reduced diameter section is located in the upper half when installing the crystallizer, so that the circulating water is closer to the core of the molten iron, ensuring that the cooling speeds of the molten iron in the upper half and the lower half in the crystallizer are the same.
