The foundry technology is a process of receiving cast preparations by filling of the melted metal in forms which cavity repeats a casting configuration. When cooling metal hardens and obtains a form cavity configuration.
Molding receive various designs of castings weighing from several gram to 300 t, from several centimeters to 20 m long, with walls 0,5-500 mm thick (blocks of cylinders, pistons, cranked shaft, cases and covers of reducers, cogwheels, beds of machines, beds of rolling mills, turbine shovels, etc.). Castings receive from black alloys (chuguna, became) itsvetny alloys (aluminum, magnesian, copper, zinc, titanic, etc.).
