Molten tin
Tin melt refers to the melt (the liquid state of aggregation ) of the metal tin , which is used, for example, for the casting of cast parts, as well as an industrial plant for its production. In some cases, historical buildings continue to be called tin smelting despite their conversion, for example as a restaurant or cultural center.
history
The tin, which has been known since the Bronze Age, has been used from the early Middle Ages to manufacture tin cast products such as cutlery, pewter figurines and devices for church use. Since that time, the pewter caster has been a special craft that has survived to this day, albeit to a very limited extent. With industrialization, the use of tin casting changed with the development of new materials. Utensils were no longer used, but tin molds were added, for example for the rubber industry, electronic components and jewelry in various tin alloys.
Procedure
The solid tin is made castable in crucibles by heating it to approx. 160–300 ° C and adding antimony , lead and copper . The resulting molten tin can now be poured into prepared molds and, after cooling, results in a metallic workpiece. This process is also known from traditional lead casting , in which, contrary to the name, tin is used instead of lead.
