Multi-stage phase change recovery and storage device for heat in continuous casting and billet cooling process

Abstract

The invention relates to a multi-stage phase change recovery and storage device for heat in continuous casting and billet cooling processes. A phase change energy storage material is used for recovering and storing a large amount of high-temperature heat generated in continuous casting and high-temperature billet stacking and cooling processes in a metallurgy process. The device comprises a high-temperature continuous casting process phase change recovery energy storage cover, a billet conveying device, a billet stacking cooling chamber and a control system. The high-temperature continuous casting process phase change recovery energy storage cover is used for recovering and storing heat energy in the continuous casting process, and the billet stacking cooling chamber is used for recoveringand storing heat energy in the billet cooling process. The device has the beneficial effects that a large amount of heat released in the high-temperature metal continuous casting process and the billet stacking and cooling process is recovered and stored by using the phase change energy storage material in a multi-stage mode, the recovered and stored heat is used for steam power generation, heatrecovery is sufficient, and meanwhile the energy utilization rate is increased.

Description

technical field [0001] The invention belongs to the technical field of energy recovery and reuse in the metallurgical industry, and in particular relates to a multi-stage phase change recovery and storage device for heat in continuous casting and billet cooling processes. Background technique [0002] As the concepts of energy saving, environmental protection, low consumption and high efficiency gradually penetrate into the metallurgical industry, more and more metallurgical enterprises begin to pay attention to the recycling and efficient utilization of resources, thereby reducing raw material input and saving production costs. [0003] Continuous casting is continuous casting of steel. Compared with the traditional die casting method, continuous casting can greatly improve the metal yield and slab quality, and save energy, so it is widely used in the field of iron and steel metallurgy. However, during the continuous casting process, the high-temperature metal is exposed to...
