Abstract
Sposób wytwarzania odlewów z żeliwa wysokoaluminiowego charakteryzuje się tym, że wytopiony stop, zawierający wagowo: 29-40% aluminium, 5-30% chromu, 0,8-2,5% węgla, 0,9-1,8% krzemu, 0,2-0,5% manganu, 0,005-0,02% fosforu, 0,001-0,004% siarki, reszta żelazo i nieuniknione zanieczyszczenia, przegrzano do temperatury powyżej 1400°C, po czym wprowadzono mieszaninę, korzystnie w postaci granulatu, składającą się z boru w ilości 0,005-1,0% wagowych i bizmutu w ilości 0,001-0,5% wagowych. Następnie ciekły stop odlano do form, a otrzymane odlewy poddano obróbce termicznej poprzez wygrzewanie w temperaturze 750-1100°C przez okres co najmniej 20 godzin i chłodzeniu razem z urządzeniem grzewczym.The method of producing high-aluminum iron castings is characterized in that the melted alloy, containing by weight: 29-40% aluminum, 5-30% chromium, 0.8-2.5% carbon, 0.9-1.8% silicon, 0 , 2-0.5% manganese, 0.005-0.02% phosphorus, 0.001-0.004% sulfur, residual iron and unavoidable impurities, overheated to a temperature above 1400 ° C, after which a mixture, preferably in the form of granules, consisting of boron in an amount of 0.005-1.0% by weight and bismuth in an amount of 0.001-0.5% by weight. Then the liquid alloy was cast into molds and the resulting castings were heat treated by heating at 750-1100 ° C for a period of at least 20 hours and cooling together with the heating device.
