Description

Technical Field

[0002] The electric arc furnace is an electric furnace that uses the high temperature generated by the electrode arc to melt ores and metals. The tilting mechanism of the electric arc furnace is an important part of the electric arc furnace equipment, which is mainly used to realize the tilting operation of the furnace body to carry out the process of tapping steel and slag. The design and function of this mechanism have an important impact on the production efficiency and molten steel quality of the electric arc furnace.

[0003] During use, the existing furnace tilting mechanism usually adopts a hydraulic cylinder to drive the furnace body to tilt, and it is not limited, resulting in poor stability during tilting. It needs to be tilted slowly, which is not convenient for quickly completing material dumping, reducing production efficiency and stability in use. In addition, most electric arc furnaces are usually designed with guide wheels on both sides of the furnace door, and the furnace door is moved by the guide wheels, and then the furnace door is opened and closed. However, each set of guide wheels is not completely consistent and there is a certain deviation. Since the guide wheels need to bear the weight of the furnace door and the friction during movement, they wear faster, and the inconsistency of the guide wheels will accelerate this wear process, resulting in jamming, shaking and other problems during the opening and closing of the furnace door. This structure has high requirements on the processing accuracy of components, and has low stability during long-term use, thereby increasing the maintenance cost of the device.
