The invention discloses a device and a method for heating waste steel by using hot disintegration waste heat of steel slag. The device comprises a steel slag hot disintegration pool and a driving device which are arranged on a base. The steel slag hot disintegration pool comprises a pool top cover, a pool body side wall, a pool bottom cover and a steel scrap cage; the tank top cover, the tank body side walls and the tank bottom cover are encircled to form a closed space to wrap the scrap steel cage; a waste steel cage groove hole is formed in a pool bottom cover in the steel slag hot disintegration pool; the steel scrap cage slotted hole is matched with the steel scrap cage; a scrap steel cage bottom cover is arranged at the bottom of the scrap steel cage slot, and a scrap steel cage top cover is arranged at the top; the driving device comprises a pool top cover driving arm and a steel scrap cage bottom cover driving arm; the driving device can drive the pool top cover and the steel scrap cage bottom cover to be opened and closed. According to the scheme, the waste steel can be preheated by utilizing sensible heat in the steel slag hot disintegration treatment process, the charging temperature of the waste steel is increased, the smelting period is shortened, and the use proportion and the use level of the waste steel are improved.
Description
technical field [0001] The invention relates to the field of steelmaking, in particular to a device and a method for heating scrap steel by using the stuffy waste heat of steel slag. Background technique [0002] Steel slag is the main by-product in the steelmaking process, and the production amount is about 8%~15% of the crude steel output. The amount of steel slag produced by China's iron and steel industry is nearly 100 million tons every year. Since steel slag contains valuable elements such as Fe and CaO, it is of great significance to use it as a resource. At present, steel slag in the iron and steel industry mainly recovers metallic iron through crushing, screening, and magnetic separation. Tailings are mainly used as raw materials for cement production or cement concrete admixtures. It is used to cool the hot steel slag to normal temperature, and at the same time to crush the steel slag and separate the slag and iron. Hot stuffing process is the mainstream process ...
