[0028] In the steelmaking process, it is often necessary to add flux in the steelmaking process. Its main function is to combine with impurities in the minerals to form slag and separate it from the metal to achieve the purpose of smelting or refining. It is to make insoluble substances into soluble substances for the convenience of analysis. The existing various flux materials need to be mixed when they are used. The general mixing method adopts a stirring kettle for stirring and mixing. This method can only achieve the purpose of simple material mixing. It cannot effectively remove materials of different sizes, so that the speed of melting the materials in the materials is different, which may affect the normal use of the subsequent flux. When the device is used, an external power supply is connected. When in use, the flux The material is put into the mixing kettle 1 through the feed cover 3. The material of normal particle size falls smoothly through the filter screen 8, while some larger materials are located above the filter screen 8. When stirring and mixing, the stirring shaft 7 is driven to rotate by starting the mixing motor 4. The stirring shaft 7 can drive the stirring rod 15 and the driving gear 9 to rotate. The stirring rod 15 can mix the materials normally, and the driving gear 9 can drive the outer driven gear 10 to rotate.
