As a scarce resource, tin was the first ancient metal discovered and utilized. It has been accompanying the development of human science and technology and is an indispensable and important raw material for modern science and technology. At present, China's tin reduction smelting devices are mainly reverberatory furnace, electric furnace, etc., and there are also a few short kilns and individual blast furnaces. In the 1970s, the research on tin smelting devices made great progress, and products such as Kaldor furnaces were successively released. Compared with other production equipment, it has significant advantages.

Reverberatory furnaces were first used in the United Kingdom in the early 18th century. After the regenerator was installed in the early 19th century, it developed rapidly. Later, waste heat boilers, water pipe cooling furnace bottoms, suspended furnace tops and other technologies were added. After a series of It has been transformed and improved and is now the main equipment for tin smelting. Reverberatory furnace smelting essentially uses high-temperature gas generated by burning fuel to heat the charge through the furnace space, so that the charge is reduced at high temperature to generate coarse tin slag. Worldwide, more than 70% of tin is smelted using reverberatory furnaces.

At present, China mainly produces the technological process of reduction smelting of tin concentrate - fire refining of crude tin - solder electrolysis or vacuum distillation - tin slag fumigation treatment. The reduction smelting devices used are reverberatory furnace and electric furnace, of which reverberatory furnaces are the main ones. , the output is about 85%. The smelting process of tin has been developed along with the advancement of human science and technology. From the ancient Bronze Age to the modern high-tech period, its smelting process has been improving, and its use areas have also been increasing. Yueguang has become an indispensable and important material in many cutting-edge technological fields such as electronics and information.
