Necessity of automation of information support at organization of cast works operation is discussed.
The casting process analysis technique with the help of Pro CAST package applied at the Minsk Tractor Plant is described.
The authors of the article describe changes in preparation process of cast parts manufacture caused by application of three-dimension computer design.
А computer-aided design of а set of documents of technological processes in foundry production is examined.
Experience of operation of “Henrich Wagner Sinto'' molding line in cast-steel works No. 2.
Experience of the scientific and production enterprise ''Technikon” in creation of new and modernization of operating control systems over technological processes in different industrial branches is described.
During 1997—2001 the Minsk Tractor Plant and Unitary enterprise "Oktava'' ran a range of measures of creation and implementation of computer-aided systems of burdening electric furnaces and cupola in cast-steel works of the Minsk Tractor Plant.
The technological process of manufacture of castings out of high-strength case iron in conditions of cast-steel works of Minsk Tractor Plant is described.
Experience of high-precision parts production with application of hot cross-wedge rolling method in the forge shop of the Minsk Tractor Plant is examined in the article.
The author examines deformation processes of castings of machine building parts of white, gray, malleable and high-duty cast iron by forging, forming, rolling, compaction.
The article cites recommendations of deformation mode and examples of application of deformed castings for machine building parts.
Structure and mechanical properties of gray, malleable, while and high-duty cast iron after deformation in hot conditions by smithing, stamping, extrusion and rolling are considered. Influence of hot plastic deformation of castings on the following phase change in the structure of cast iron is shown.
Metallurgy
