Testing the Veining Elimination using Pressure Changes and one Type of Additive in a Cold-box-amine Core Mixture

Autor: P. Delimanová, I. Vasková, O. Kožej

Publikováno v: Archives of Foundry Engineering, Vol vol. 24, Iss No 3, Pp 129-135 (2024)

This article presents a analysis of the impact of varying amounts of a specific additive in the core mixture and adjustments in shooting pressure on the elimination of surface defects in castings, particularly veinings. These defects, often located i

Influence of Shape of Gating System on Pouring Time and Filling of a Sprue with the Use of MAGMA5 Optimization

Autor: I. Vasková, D. Fecko, P. Delimanová, L. Jankovčin, M. Hrubovčáková

Publikováno v: Archives of Metallurgy and Materials, Vol vol. 69, Iss No 3, Pp 1131-1136 (2024)

Present hectic times do not allow the foundrymen to test various modifications of gating system in real production due to lack of time and efficiency of production phase. When testing of tens or hundreds of modifications is needed, simulation softwar

Comparison and evaluation of the cast iron castings surface using different types of foundries sands

Autor: Petra Delimanová, Iveta Vasková

Publikováno v: Results in Materials, Vol 23, Iss , Pp 100617- (2024)

This study investigates and compared various properties of high-quality foundry sands on the surface quality of castings, whose cores are produced using the col-box method. Methods such as the measurement of flushable fraction, sieve analysis, electr

Influence the Composition of the Core Mixture to the Occurrence of Veinings on Castings of Cores Produced by Cold-Box-Amine Technology

Autor: P. Delimanová, I. Vasková, M. Bartošová, M. Hrubovčáková

Publikováno v: Archives of Metallurgy and Materials, Vol vol. 68, Iss No 3, Pp 947-953 (2023)

The main problem in the cores production by cold-box method is the occurence of surface defects due to the tension generated by thermal expansion of the silica sand. One of the possibilities of eliminination is exchange of silica sand from another lo
