Technical Field
[0001] This utility model relates to the field of converter ironmaking technology, specifically to an environmentally friendly converter refueling material feeding device. Background Technology
[0002] The converter lining replenishment device is a key piece of equipment for maintaining the converter lining during steelmaking. During steelmaking, the converter lining is subjected to prolonged physical and chemical erosion from molten steel and slag at temperatures exceeding 1600℃, making it highly susceptible to refractory material spalling and damage. When the lining thickness decreases to a certain extent, it not only reduces the converter's service life but may even lead to serious safety accidents such as steel leakage. Therefore, timely replenishment of lining materials into the furnace through the replenishment device to repair damaged areas is essential for extending converter life and ensuring continuous steelmaking.
[0003] For example, Chinese utility model patent application number 202223267673.2 discloses an automatic feeding machine for repairing converter steelmaking. By using an electric winding roller to wind and release the first and second cables at the same speed, the height of the feeding box can be changed, ensuring the distance between the feeding box and the repair site is at a suitable length, guaranteeing the repair effect. Using this method to raise and lower the feeding box, the top height of the device is fixed, preventing impact on the inner wall of the converter. Compared to some related equipment that can only control the height of the feeding box through a second pneumatic push rod, it has greater versatility. However, this device still has certain shortcomings.
[0004] When adding the furnace lining material to the feeding box, residual material may remain, resulting in insufficient feeding and a lower actual amount of material than the theoretical value, thus weakening the furnace lining repair effect.
[0005] Therefore, we propose an environmentally friendly converter refueling material feeding device to solve the problems mentioned above. Utility Model Content
