Abstract
The subject of the work is to prove that correct inoculation improves the properties of high chromium cast iron. The analysis was performed in terms of the effect of Fe-Nb-based and Fe-Ti-based inoculators on the starting alloy. Defects in castings such as porosity cracks and shrinkage cavities are a huge problem for companies producing chromium iron range. Reducing the occurrence of the aforementioned defects will result in more profitable and repeatable production. A stabilized and controlled production process provides guarantees of competitiveness in terms of price as well as timing in the market. It seems that the procedure of inoculation of HCCI cast iron, which has not yet been implemented on an industrial scale, turns out to be helpful in these problems. The inoculation used should have a significant effect on the fragmentation of the primary austenite structure as well as affect the alloy in the area of carbide eutectic crystallization. The thesis that can be formulated is that the inoculation will allow to improve the functional properties of castings free from defects such as hot cracking. Industrial tests were carried out at the “Swidnica” Foundry Ltd. which made it possible to show that it is possible to perform correct inoculation of high chromium cast iron under the conditions of the foundry's production line. In addition, it was shown that the inoculation of Fe-Nb better than Fe-Ti affects the functional properties of the inoculated alloy. It turned out that a small addition of Fe-Ti inoculant leads to the formation of TiC carbides. In contrast, the formation of NbC carbide was not demonstrated in the study with the use of Fe-Nb inoculant. In this case, the formation of an intermetallic phase was observed.
