| titleOfInvention | Scrap steel preheating and continuous feeding system constructed based on waste heat recovering channel of electric-arc furnace and application method of system |
| abstract | The invention discloses a scrap steel preheating and continuous feeding system constructed based on a waste heat recovering channel of an electric-arc furnace and an application method of the system. The waste heat recovering channel of the electric-arc furnace is formed by connecting a flow guide tube, a transition tube, a heat exchange and material storing box and a preheating channel, wherein hot gas sequentially flows through the flow guide tube, the transition tube, the heat exchange and material storing tube and the preheating channel; a scrap steel storing box, a heat-resistant chain scraper conveyor and a hydraulically-controlled feeding trolley are mounted on a foundation of the waste heat recovering channel of the electric-arc furnace to form the scrap steel preheating and continuous feeding system; the scrap steel is conveyed from low to high through the chain scraper conveyor in the preheating channel and continuously fed into the heat exchange and material storing box to be stacked, and then the feeding trolley at the inner bottom part of the heat exchange and material storing box can continuously intermittently move to push the scrap steel by layers from the bottom into the electric-arc furnace to smelt; the scrap steel fed into the furnace is at the temperature exceeding 900 DEG C, and more than 120kW.H/T of electricity can be saved; the gas can be discharged from the preheating channel while being cooled to be 100-150 DEG C and then dedusted for later use, and thus the energy can be saved, and the consumption can be decreased; in addition, the continuous feeding system does not affect the automatic slag flowing and tapping works of the electric-arc furnace. |
