FOUNDRY

The foundry facilities enable us to manufacture the parts of carbon, alloy, high-alloy steel grades; to cast parts of grey cast iron, high-strength cast iron, bearing cast iron and special iron. For producing nonferrous castings bronze, aluminium and tin and lead alloys are used.
Molds for light castings are made in the pulse molding line. Molds for medium-size castings are produced in bumping molding machines by means of lash method and using a wide range of chemically solidifying compounds. Molds for heavy and large-size castings are made by hand molding with usage of chemically solidifying compounds on the basis of furan resins.
Prior to casting, steel is subjected to after-furnace ladle steel treatment in the Ladle-furnace unit.

For nonferrous castings there is a stock of centrifugal casting machines with vertical and horizontal axis of rotation and for castings of aluminium alloys the chill casting technique can be used. Fettling and cleaning of castings are performed. Castings may be subject to heat treatment:
- annealing for stress relief and hardness reduction;
- hardening;
- normalizing;
- normalizing with tempering;
- surface hardening and so on.
