Description

Technical Field

[0002] Most metals react readily with oxygen in the air to form oxides. To obtain pure metals, a reducing agent is needed to react with the metal oxides. Reduction furnaces are commonly used reduction equipment. A reduction furnace is a device used to reduce metal oxides. Its principle is to use a high-temperature reduction reaction to reduce the metal oxide into a metal. The metal oxide is added to the reduction furnace, heated to a high temperature, and then reacts with the reducing agent to be reduced to a metal. The reducing agent can be hydrogen, carbon, or a mixture of hydrogen and carbon. The main components of a reduction furnace include the furnace body, heater, reducing agent inlet, metal oxide inlet, and metal collector. Reduction furnaces have a wide range of applications, including metallurgy, chemical engineering, and materials science.

[0029] Furthermore, when feeding materials into the batching cylinder 7, the weighing sensor 6 can accurately monitor the amount of materials fed, and the weight data will be transmitted to the digital display 12, so that personnel can control the amount of materials fed in real time, thereby accurately controlling the amount of metal oxides and reducing agents fed, and ensuring the accuracy of the raw material ratio.

[0030] It should be noted that the telescopic tube 10 enables a flexible connection between the feeding cylinder 7 and the screw feeder 4, thereby avoiding any impact on the balancing.
