CALIBOCHIROCHISI

The Calibochirochisi (from ancient greek χάλυψ, chalübs, «steel»; κηρός, cherós, «wax»; χύσις, chüsis, «melt») is an industrial process for the lost wax casting of steel or ferrous minerals in carbon alloy in general. This technique allows to obtain low thickness hollow shapes and therefore light and economically advantageous. The method requires a complementary intervention of various disciplines, aimed at obtaining a steel product that would otherwise not be achievable. In the beginning we find the molding of a wax model form a prototype of any material and shape, which can be deferred as an execution to that used in artistic bronze foundries. The coating by means of a layer of calcined and silicate kaolins guarantees the preservation of the imprint of the wax form, inside a shell capable of supporting, after cooking, the heat and pressure of the molten steel. Once cooled, the mold is opened and the inner core, obtained during the kaolinization process, emptied. Over time, the need to use a process that would replace the stirrup technique in the steel industry, or more simply the casting of ferrous material in sand, has obtained its response thanks to the invention of the method
