Maintaining the stability of the strength and microstructure parameters of this cast iron is the goal of a series of studies on the control of graphitization and austenitic inoculation (increasing the number of primary austenite dendrites), and which affects the type of metal matrix in the structure. The ability to graphitize the molten alloy decreases with its holding in the melting furnace more than an hour. The tendency to crystallize large dendritic austenite grains and segregation of elements such as Si, Ni and Cu reduce the ductility properties of this cast iron. The austenite inoculation process may introduce a larger number of primary austenite grains into the structure, affecting the even distribution of graphite and metal matrix precipitation in the structure. Known inoculation effects the interaction (in low mass) of additives: Sr, Ca, Ba, Ce, La, produces MC2 carbide). Addition of Fe in the inoculant influences the number and shape of austenite dendrites. Hybrid modification combines the effects of these two factors. The introduction of nucleation sites for the graphite eutectics and primary austenite grains result in the stabilization of the cast iron microstructure and an increase in mechanical properties. The obtained test results set the direction for further research in this area in relation to the production of heavy plate castings in vertical and horizontal pouring.}, type={Article}, title={The Method of Inoculation of High-Quality Grey Cast Iron Intended for Massive Castings for Bottom and Distance Plates as Well Counterweights Manufactured as Vertical Castings}, URL={http://journals.pan.pl/Content/126272/PDF-MASTER/AMM-2023-1-48-Szczesny.pdf}, doi={10.24425/amm.2023.141512}, keywords={high-quality cast iron, heavy castings, massive casting, graphitizing inoculation, hybrid inoculation}, }
