Title:
RAPID FEEDING DEVICE AND METHOD FOR FEEDING SCRAP STEEL INTO ELECTRICAL FURNACE
Document Type and Number:
WIPO Patent Application WO/2012/145967
Kind Code:
A1
Abstract:
Disclosed are a rapid feeding device and a feeding method for feeding scrap steel into an electrical furnace. The rapid feeding device comprises a high temperature coupling tank (10) in communication with the electrical furnace, and a cold material-receiving device for feeding in the scrap steel. The cold material-receiving device comprises a long feeding groove (2) that can be hoisted. The long feeding groove (2) has a discharge port (2a) made at its front end, that can be in sealed communication with a feeding port of the high temperature coupling tank (10). The rapid feeding device has good air tightness and a high feeding speed. The feeding is carried out in closed conditions, which can effectively reduce air leakage, and improve the performance of the electrical furnace dedusting system. The discharge port is made at the front end of the long feeding groove so that the thickness of the spread material can be easily controlled.
