Description

Technical Field

[0001] The utility model belongs to the technical field of casting processing, and specifically relates to a medium frequency melting furnace for roller blank processing. Background Art

[0002] Roller blank processing is a key industrial manufacturing process, which is mainly used to produce preliminary blanks of various types of rollers. During processing, raw materials such as metals or alloys need to be melted into liquid to provide liquid metal for subsequent casting or molding processes. The longest-used melting device is the medium-frequency melting furnace, which has the characteristics of small size, simple operation, fast melting speed, no open flame, low consumption, energy saving, environmental protection, no dust, safety and reliability. After the melting is completed, the medium-frequency melting furnace needs to tilt the furnace body to pour out the molten metal. However, since the height of the molten metal in the furnace is not fixed, the furnace body tilts. The tilting angle is also different. Therefore, the position of the receiving device needs to be adjusted by people as the furnace body gradually tilts, and there is a certain distance between the receiving device and the guide groove of the furnace body, and the inclination angle of the guide groove of the melting furnace will gradually increase. When the molten metal enters the guide groove, it will flow downward quickly until it flows into the receiving device. However, since the molten metal flows too fast and there is a certain distance between the guide groove and the receiving device, when the molten metal enters the receiving device, the molten metal will splash outward. The temperature of the splashed molten metal is high, which will bring safety hazards to the surrounding staff. Utility Model Content
