Abstract
Przedmiotem zgłoszenia jest kompozyt na osnowie stopów żelaza, który charakteryzuje się tym, że zawiera stop żelaza o udziale masowym 28 ÷ 98,5% oraz węglik krzemu o technicznej czystości SiC > 80% i ziarnistości w zakresie 0,5 ÷ 6,7 mm oraz udziale masowym 1,5 ÷ 72%, zgłoszenie obejmuje też sposób wytwarzania kompozytu na osnowie stopów żelaza, który polega na tym, że stop żelaza o udziale masowym 28 ÷ 98,5% miesza się z węglikiem krzemu o udziale masowym 1,5 ÷ 72% i ziarnistości w zakresie 0,5 ÷ 6,7 mm, przy czym węglik krzemu aktywuje się przez wymieszenie go z krzemianem sodu w ilości 3 ÷ 8% w stosunku do masy SiC w temperaturze od 80 do 400°C w czasie 0,5 ÷ 4 godzin, następnie tak przygotowaną porcję węglika krzemu umieszcza się w układzie wlewowym lub we wnęce formy, robocze części odlewu umieszcza się w górnej części formy wykonanej, korzystnie z osnowy kwarcowej z bentonitem, po czym formę zalewa się ciekłym odlewniczym stopem żelaza o temperaturze od 1380 - 1580°C, po wybiciu zakrzepłego odlewu poddaje się go obróbce mechanicznej.The subject of the application is a composite based on iron alloys, characterized by the fact that it contains an iron alloy with a mass fraction of 28 ÷ 98.5% and silicon carbide with technical purity SiC> 80% and a grain size in the range of 0.5 ÷ 6.7 mm and with a mass fraction of 1.5 ÷ 72%, the application also covers a method of producing a composite based on iron alloys, which consists in the fact that an iron alloy with a mass fraction of 28 ÷ 98.5% is mixed with silicon carbide with a mass fraction of 1.5 ÷ 72 % and grain size in the range of 0.5 ÷ 6.7 mm, while silicon carbide is activated by mixing it with sodium silicate in the amount of 3 ÷ 8% in relation to the SiC weight at a temperature of 80 to 400 ° C for 0.5 ÷ 4 hours, then the prepared portion of silicon carbide is placed in the gating system or in the mold cavity, the working parts of the casting are placed in the upper part of the mold, preferably made of a quartz-bentonite matrix, and then the mold is poured with a liquid casting iron alloy with a temperature of 1380 - 1580 ° C, after breaking the solidified casting is mechanically processed.
