Innovative introduction of ductile iron with bainitic carbide-bainitic structure, material and design for the production of wear components for industrial mixers

This project is linked to the innovative deployment of ductile iron with bainitic and carbidopa bainitic structure of the metal base, as material for the production of wear components for industrial mixers. Recent studies have shown that combinations of strength and toughness, which can be achieved in isothermal hardening of spheroidal graphite cast irons with (CHSG) superior to those of ductile iron with other structures of the metal base. The combination of high static and dynamic strength with high durability allows them to be used as construction material in terms of friction and stress reversal applications, competing forged carbon and low-alloy steels. This material successfully used for the production of gears, crankshafts and camshafts, rolling rolls, pumps, railway and automotive industries. Achieved the replacement is best characterized isothermal Hardened CHSG: 1. Lightening of the parts due to the lower density of CHSG compared to steel. 2. Increased smoothness of operation and durability of the gear - the presence of graphite structure provides better lubrication and less prone to pitting. 3. Better machinability. 4. Lower energy costs To achieve high strength properties of complex requires reliable receiving free carbides and brittle phases bainite-austenitic metal base. It is a complex function of: the chemical composition, condition of the alloy structure, the temperature and time of the isothermal tempering. Carbidopa bainitic ductile iron (CADI) are a new class of isothermal hardening spheroidal graphite cast irons with for work in conditions of friction with high contact stresses and intensive exports. Combining tough bainite-austenitic metal matrix arranged in her hard-wear-resistant carbide phase and soft-graphite makes it a promising anti-friction and wear-resistant material.
