Abstract
Przedmiotem zgłoszenia jest żeliwo ausferrytyczne o podwyższonej wytrzymałości na ścieranie zawierające w swoim składzie węgiel, krzem, mangan, fosfor, siarkę, magnez, nikiel, molibden, miedź i chrom. Żeliwo charakteryzuje się tym, że zawiera (w % masowych): 3,5 - 3,7% węgla; 2,4 - 2,6% krzemu; 0,16 - 0,17% manganu; 0,04 - 0,045% fosforu; max. 0,015% siarki, 0,036 - 0,042% magnezu; 1,4 - 1,45% niklu; 0,2 - 0,28% molibdenu; 0,6 - 0,65% miedzi; 0,45 - 0,5% chromu oraz 0,033 - 0,035% boru; reszta żelazo. Zgłoszenie obejmuje też sposób wytwarzania odlewów z żeliwa o podwyższonej wytrzymałości na ścieranie, który charakteryzuje się tym, że wytopiony stop, zawierający (w % masowych): 3,5 - 3,7% węgla; 2,4 - 2,6% krzemu; 0,16 - 0,17% manganu; 0,04 - 0,045% fosforu; max. 0,015% siarki; 0,036 - 0,042% magnezu; 1,4 - 1,45% niklu; 0,2 - 0,28% molibdenu; 0,6 - 0,65% miedzi; 0,45 - 0,5% chromu oraz 0,033 - 0,035% boru; reszta żelazo, przegrzewa się do temperatury 1500°C i wytrzymuje w niej przez okres 5 minut, a następnie przeprowadza się zabieg sferoidyzowania i modyfikowania grafityzującego w ilości 0,6% masowego, po czym ciekły stop odlewa się do form odlewniczych, a następnie otrzymany odlew poddaje się oczyszczeniu. Oczyszczony odlew poddaje się austenityzowamu w temperaturze (T?) 950°C w czasie ??2,5 godziny, po czym odlew hartuje się w kąpieli solnej o temperaturze wybranej z zakresu 200°C do 320°C z przemianą izotermiczną w czasie 2 godzin. Przedmiotem zgłoszenia jest też zastosowanie żeliwa ausferrytycznego chromowo - borowego do wytwarzania odlewów odpornych na zużycie ścierne zwłaszcza w postaci elementów oczyszczarek śrutowych, elementów części maszyn rolniczych i drogowych oraz innych odlewów.The subject of the application is ausferritic cast iron with increased abrasion resistance, containing carbon, silicon, manganese, phosphorus, sulfur, magnesium, nickel, molybdenum, copper and chromium. Cast iron is characterized by the fact that it contains (in mass%): 3.5 - 3.7% carbon; 2.4 - 2.6% silicon; 0.16 - 0.17% manganese; 0.04 - 0.045% phosphorus; max. 0.015% sulfur, 0.036 - 0.042% magnesium; 1.4 - 1.45% nickel; 0.2 - 0.28% molybdenum; 0.6 - 0.65% copper; 0.45 - 0.5% chromium and 0.033 - 0.035% boron; iron rest. The application also includes a method of producing iron castings with increased abrasion resistance, which is characterized in that the melted alloy containing (in mass%): 3.5 - 3.7% carbon; 2.4 - 2.6% silicon; 0.16 - 0.17% manganese; 0.04 - 0.045% phosphorus; max. 0.015% sulfur; 0.036 - 0.042% magnesium; 1.4 - 1.45% nickel; 0.2 - 0.28% molybdenum; 0.6 - 0.65% copper; 0.45 - 0.5% chromium and 0.033 - 0.035% boron; the rest is iron, overheated to a temperature of 1500 ° C and withstands in it for a period of 5 minutes, followed by spheroidizing and graphitizing modification in an amount of 0.6% by mass, after which the liquid alloy is poured into foundry molds, and then the resulting casting undergoes purification. The cleaned casting is subjected to austenitizam at a temperature of (T?) 950 ° C for ?? 2.5 hours, after which the casting is quenched in a salt bath at a temperature selected from the range of 200 ° C to 320 ° C with isothermal transformation during 2 hours . The subject of the application is also the use of chromium boron ausferritic cast iron for the production of wear-resistant castings, in particular in the form of shot blasting machines, elements of agricultural and road machinery as well as other castings.
