vacuum furnace
Compared with other processing technology, metal heat treatment generally
does not change the shape of the workpiece and the overall chemical composition,
but by changing the microstructure of the workpiece, or by changing the chemical
composition of the workpiece surface, endow or improve the workpiece
performance.
Metal heat treatment is characterized by improving the internal
quality of the workpiece, which is not generally visible to the naked eye. In
order to make the metal workpiece have the required mechanical, physical and
chemical properties, heat treatment process is often an important process step
in addition to the rational selection of materials and forming process.
Iron
and steel is a kind of material widely used in machinery industry. The
microstructure of iron and steel is complex and can be controlled by heat
treatment. So the heat treatment of iron and steel is the main content of metal
heat treatment. In addition, Al, Cu, Mg, Ti and their alloys can also be heat
treated to change their mechanical, physical and chemical properties to obtain
different performance.
