Description

Technical Field

[0001] The utility model relates to the technical field of solder processing equipment, in particular to a melting furnace for solder production and processing. Background Art

[0002] The melting temperature of solder used in fusion welding is typically no lower than the solidus of the parent metal, and its chemical composition, mechanical, and thermal properties are similar to those of the parent metal. Examples include various welding rods and flux-cored wire. The resulting weld strength is often no lower than that of the parent metal itself. In contrast, the melting temperature of brazing filler metals must be lower than the solidus of the parent metal, and their chemical composition often differs significantly from that of the parent metal. This results in a fine, precise weld seam, but often lacks strength and corrosion resistance. When solder is used, as in arc welding, the temperature often exceeds that of both the parent metal and the filler metal itself, and there is no distinction between soft and hard filler metals. Among these filler metals, hard filler metals, such as copper-zinc filler metals (copper-zinc alloys) and silver filler metals (silver-copper alloys), produce stronger joints and are primarily used to connect metal components requiring high strength. Soft filler metals, such as solder (a tin-lead alloy), produce weaker joints and are primarily used to connect smaller joints where strength is not critical, such as those in electronic instruments, meters, and electronic circuits in household appliances.

[0003] Currently, solder needs to be smelted before processing, which requires the use of a smelting furnace. A smelting furnace is a device that melts metal ingots and some scrap metals, adds necessary alloy components, and then smelts them into the required alloy through operations such as slagging and refining.

[0004] However, in current melting furnaces, most of the liquid solder is stirred manually using a stirring rod or a simple stirrer. This method can easily lead to uneven and insufficient heating of the liquid solder, which in turn results in poor solder melting effect and is not conducive to further processing of the solder. The stirring method is relatively simple and the stirring efficiency is low, which affects the production efficiency of solder melting. Utility Model Content
