Description

Technical Field

[0001] The present invention relates to the technical field of casting and smelting, and in particular to a casting and smelting device and a method for using the same. Background Art

[0002] Smelting is one of the casting production processes. It is a pyrometallurgical process in which metal materials and other auxiliary materials are put into a smelting furnace for melting and tempering. The materials in the high-temperature furnace undergo certain physical and chemical changes to produce crude metal or metal enrichment and slag.

[0003] In the prior art, during smelting, metal materials and other materials are added to a smelting furnace, and the metal is melted by a heating component. However, since the raw materials in the smelting furnace contain a variety of materials, when the metal is melted, metal elements of different masses are unevenly distributed inside the smelting furnace, affecting the quality of the subsequent cast metal. Therefore, workers are required to manually stir the molten gold with sticks, which is not only cumbersome but also dangerous. At the same time, since a certain amount of metal slag and oxide slag will appear after the metal materials and other materials are added to the smelting furnace, when the metal melt is poured, the flow of the slag needs to be controlled, and the pouring process is relatively cumbersome.

The second return spring will pull the positioning rod to drive the positioning rod to slide relatively downward inside the slide hole. When the collecting frame rises to the top of the smelting furnace body, the mounting plate will press down on the top of the extrusion rod, which will drive the collecting frame to rotate and tilt, and the slag can slide out along the inside of the collecting frame.

[0019] The present invention provides a casting smelting device and a method for using the same, which have the following beneficial effects:

[0020] (1) The present invention places metal raw materials inside a smelting furnace body, heats and melts the metal through a heating component, and then moves a top plate through a lifting component such as a crane, so that a stirring rod liquid enters the inside of the smelting furnace body, and controls the rotation of a rotating shaft to drive a mounting rod to rotate synchronously, thereby stirring the molten metal inside the smelting furnace body. At the same time, the mounting rod is reciprocated and lifted inside the rotating shaft, thereby synchronously pushing and stirring the molten metal inside the smelting furnace body, thereby achieving sufficient mixing of the molten metal.
