Description

Technical Field

[0001] The utility model relates to the technical field of lead melting furnaces, and more specifically, to an energy-saving lead melting furnace capable of reducing the generation of lead slag. Background Art

[0002] At present, gravity casting mode, continuous casting and continuous punching mode, and continuous casting mode are generally used in the manufacturing process of battery grids. The lead melting furnace used in these three grid manufacturing processes is a cylindrical lead melting furnace. Because in the production process of continuous casting and continuous punching, about 80% of the returned materials need to be returned to the lead melting pot. At the same time, in order to ensure the stability of the process temperature of the continuous casting process, at least two 30T circular lead melting pots are used. The first lead melting furnace is a lead ingot melting furnace used for melting lead ingots and residual materials produced in the subsequent continuous punching process. After the lead liquid melts to the process temperature, it is transported to the second process lead melting furnace by a lead pump. Because the two lead melting furnaces are heated by natural gas, the temperature control error accuracy in the lead melting furnace is generally ±8℃. If the temperature control accuracy of the process lead liquid insulation furnace is insufficient, the lead strip often cracks due to large temperature changes. At the same time, because two lead melting furnaces are used, the molten lead liquid is transported by a lead pump. First, the energy consumption increases, and second, the lead liquid contacts with the air more during the transportation process. More lead slag is generated after the molten lead liquid contacts with the air more.

[0003] The Chinese patent announcement number is CN220270048U, and the announcement date is December 29, 2023. The name of the application is a centralized melting furnace with a lead pressing device. The application discloses a cylindrical lead melting furnace, which is prone to produce lead slag and increase energy consumption during the continuous casting and continuous punching production process and the process of transporting molten lead.
