    Opis:
    The purpose of the study is to analyze the current state of the cast iron production and to predict production volume and cost in the near future based on the analysis results. Cast iron is one of the most common materials used in various industrial sectors. Cast iron scrap processing is the least expensive and saves both money and time. It is produced both in Russia and abroad and is one of the export types. Cast iron production significantly influences other industrial sectors. All this confirms the relevance of the study. The novelty of the study consists in the identification of the leaders among the cast-iron producers in the world and Russian metallurgical companies, as well as the determination of trends in its production at the present stage of economic development. The increasing consolidation level of cast iron producers has been revealed: China, India, Japan, and Russia represented 85% of the cast iron global production in 2019. In Russia, nine metallurgical companies account for 80% of cast iron production. In general, cast iron production in the world is stable and the import share of cast iron is about 4%. Cast iron prices tend to decline. The work identifies the lower and upper limits of the possible range of the cast iron prices. The authors conclude that the declining prices of cast iron in Russia may make its production unprofitable.

    Opis:
    The paper compares the foundry production in years 1999-2013 on a world scale, in countries counted among the leading producers of castings, and in Poland. Various types of foundry alloys were taken into account. It was found that the position of China – the leader in the world production of castings – was not changed over many years, however China's share in the total production of casting has stabilised at the level of 42-44% during the recent five years. In the analysed period of time Poland increased the share in the world production of castings from 1.07% to about 1.23%, so that Polish production of castings was almost doubled. There is a tendency on the world scale that the grey cast iron fraction in the total production of castings decreases, while an increase occurs as far as spheroidal graphite cast iron, cast steel, and aluminium alloy castings are concerned.

    Opis:
    The paper presents data illustrating the total production of castings in the world and in Poland over the 1974-2013 period. The fractions of basic casting alloys in the total amount of material used for the production of metal castings during the considered period of time were found. It was noticed that the fraction of grey cast iron castings in the total amount of the produced castings decreased significantly over the past 40 years, both on a global scale (from about 65-75% to about 45%) and in Poland (from about 75-80% to about 45-55%). The fraction of SG iron increased considerably, up to about 25% in the world, and up to about 12-16% in Poland. The fraction of malleable became almost negligible (about 1%). The fraction of cast steel took different course in Poland and in the world: it stabilised on a global scale at about 10% in recent years, but dropped down to the level of about 4-7% in Poland. The use of aluminium alloys for the production of casting grew dynamically; their fraction in the total production of casting rose from somewhat less than 4% to almost 15% on a global scale. As far as Poland is considered, this growth was ever more intensive: from about 6-8% to about 25-30% in the 1989-2013 period (the detailed data for the previous period of time are lacking).

    Opis:
    The paper presents data concerning the total production of castings over the 2000-2014 period, both on a global scale, and in Poland. The basic types of casting alloys were taken into account. Changes in the production volume and structure over the period of the analysed 15 years were pointed out with respect to countries leading in foundry production. The topmost position in the world foundry industry is held by China for several years (with almost 45% share in the foundry market), the second place is taken by India (with almost 9% share). A distinct reduction in the shares of the once significant producers of castings, such as USA, Japan, Germany, Russia, Italy, or France, was observed over the 2000-2014 period. Poland had a share of 1.16% in 2000, and of 1.02% in 2014. Comparing the detailed data concerning the years 2000 and 2014, one can see that the fractions of castings made of ductile iron, cast steel, aluminium alloys, or magnesium alloys increase on a global scale, while such alloys as grey cast iron or malleable are in decline.

    Opis:
    W artykule opisano prace związane z próbą wytworzenia odlewów z żeliwa wysokokrzemowego w warunkach przemysłowych. Zwrócono głównie uwagę na napotkane trudności w produkcji odlewów z tego materiału. Okazało się, że pomimo 100 letniej tradycji w produkcji odlewów z żeliwa wysokokrzemowego (pierwszy odlew wytworzony z tego materiału i zastosowany z powodzeniem w warunkach przemysłowych wykonano w 1907 roku p rzez francuza Jouve [1]), materiał ten nadal stwarza wiele trudności podczas procesu produkcyjnego. Należą do nich pękanie związane z wysoką kruchością lub tzw. efekt „rośnięcia” metalu związany z dużą zdolnością do absorpcji gazów przez kąpiel metalową podczas procesu metalurgicznego przygotowania stopu do odlewania [2].
    The article describes the work associated with the attempt to manufacture silicon cast iron in industrial conditions. Most attention has been paid to the difficulties encountered in the production of castings from this material. It turned out that despite 100 years of tradition in the production of silicon cast iron (first castings produced from this material and used successfully in industrial conditions were made in 1907 by Frenchman Jouve [1]), this material still poses many difficulties during the manufacturing process such as: cracking associated with high fragility or so called "grow" effect of the metal associated with large capacity to absorb gases through the metal bath during the process of preparing an alloy for casting [2].

    Opis:
    Constantly developing production process and high requirements concerning the quality of glass determine the need for continuous improvement of tools and equipment needed for its production. Such tools like forms, most often made of cast-iron, are characterized by thick wall thickness compared to their overall dimensions and work in difficult conditions such as heating of the surface layer, increase of thermal stresses resulting from the temperature gradient on the wall thickness, occurrence of thermal shock effect, resulting from cyclically changing temperatures during filling and emptying of the mould. There is no best and universal method for assessing how samples subjected to cyclic temperature changes behave. Research on thermal fatigue is a difficult issue, mainly due to the instability of this parameter, which depends on many factors, such as the temperature gradient in which the element works, the type of treatment and the chemical composition of the material. Important parameters for these materials are at high temperature resistance to thermal shock and thermal fatigue what will be presented in this paper.
