A high-efficiency waste heat recovery system for steelmaking and continuous casting

Abstract

The invention discloses a high-efficiency waste heat recovery system for steelmaking and continuous casting. A heat recovery component is installed on one side of the crystallizer base body, and several exhaust holes are equidistantly opened on the top of the crystallizer base body, and the inner side of the exhaust hole is embedded and installed. There is an exhaust fan, the bottom of the first recovery tank and the second recovery tank are welded with a deceleration tube, one end of the deceleration tube is installed with a heat conduction plate, the bottom of the second recovery tank is installed with the first water inlet pipe, and the top of the second recovery tank is installed with the first The outlet pipe accelerates the discharge of the hot steam inside the crystallizer through the exhaust fan, and discharges the hot steam into the recovery tank, and slows down its flow speed through the deceleration tube in the recovery tank, thus ensuring the heat dissipation time of the hot steam in the tank. And through the heat conduction plate to increase the heat conduction area, through two recovery tanks and continuously circulating cold water, the effect of recovering the heat energy contained in the hot steam is ensured, thereby ensuring the utilization rate of heat energy and reducing the waste of resources.

Description

technical field [0001] The invention relates to the technical field of steelmaking and continuous casting, in particular to a high-efficiency waste heat recovery system for steelmaking and continuous casting. Background technique [0002] Continuous casting is the abbreviation of continuous steel casting. In the process of producing various steel products in iron and steel plants, there are two methods of using molten steel to solidify and form: the traditional die casting method and the continuous casting method. It has significant advantages such as quality of cast slabs and energy saving. The molten steel is injected into the tundish, and the tundish distributes the molten steel to each mold from the nozzle. The mold is one of the core equipment of the continuous casting machine, which makes the castings form and rapidly solidify. crystallization. [0003] However, when the molten steel is solidified and crystallized in the current market, water will be used to directly ...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a high-efficiency waste heat recovery system for steelmaking and continuous casting, which can effectively solve the above-mentioned problem in the background technology that when molten steel is solidified and crystallized in the crystallizer, water will be used to directly cool it. The water vapor generated by the water will be discharged directly, resulting in a great waste of energy during steelmaking, which greatly reduces the energy utilization rate.
