Production technology of castings by precision casting method into ceramic moulds

Application: technology can be used to obtain: forming surfaces of rig with minimum subsequent machining; segments of grinding headset disk and cone mills for crushing wood chips, wood waste, rub­ber, plastics, etc.; figurine element (impeller) of pumps to pump oil, slurry, suspension; propeller for ships.

Advantages: high dimensional accuracy of castings; reduction of production costs compared with the manufacture of parts by machining from rolled steel; shot time of production (rapid replication); im­prove manufacturing quality (strength, durability).

Key features: the technological process includes the production of ceramic forms by pouring of liq­uid suspension in a pre-prepared special model rig with subsequent pouring of liquid metal into solidi­fied mould.

Developed: Research Laboratory «Metallurgy of Alloys», SE «Scientific and Technological Park of BNTU «Polytechnic», Dr. Artyem Andrits PhD (Cand. of Techn. Sci.), Dr. Boris Uvarov PhD (Cand. of Techn. Sci.), Pavel Lushchik.
