Description

Przedmiotem wynalazku jest zeliwo stopowe odporne na scieranie.Znane jest zeliwo stosowane na czesci maszyn i urzadzen narazone na scieranie i dzia¬ lanie ziara mineralnych, w gatunku Ni-Hard 4 o skladzie: 2,6-3,2$ Cf 1,8-3,0$ Si, 0,4-0,6$ Mn, 5-6i5% Ni, 8,0-9,0$ Cr ponizej 0,4$ MomaXf 0,06$ SimaX i 0,06$ P. Wada tego zeliwa jest to, te stop ten zawiera drogi i deficytowy nikiel.1 V wyniku badan stwierdzono nieo¬ czekiwanie, ze wysoka odpornosc na scieranie odpowiadajaoa wyzej wymienionemu zeliwu po¬ siada nowe fceliwo stopowe zwane dalej zeliwem ohromowo-manganowo-mledziowym# Zeliwo wedlug wynalazku zawiera w procentach wagowych 1,8-3,3$ wegla, 0,6-1,5$ krzemu, 1,0-3,0 manganu, 5,0-7,0$ chromu, 0,5-1,5$ miedzi ponizej 0,08$ fosforu, 0,07$ siarki i reszta zelazo* Zeliwo chromów o-manganów o-mie dzlow e wedlug wynalazku charaktery¬ zuje sie wysoka odpornoscia na soieranie, a w szozególnosoi soieranie strumieniowe i ero¬ zyjne, oraz posiada dobre wlasno soi odlewnioze.Zeliwo wedlug wynalazku moze byc stosowane na odlewy ozesoi maszyn, jak np. wykladziny przewodów pylopowietrznyoh w energetyce, zrzutni i zsypnie koksu, dyfuzory popiolu i inne elementy narazone na soieranie ziarnami mineralnymi.Przykladowo zeliwo wedlug wynalazku zawiera wagowo: C - 2,8$, Si - 1,0$, Mn - 2,5$, Cr - 595%9 Cu - 1,3$, P - 0,08$, S - 0f06$, Fe - reszta.Zastrzezenie patentowe Zeliwo stopowe odporne na scieranie, zawierajace w procentach wagowych 1,8-3$ wegla, 0,6-1,5$ krzemu, 1,0-3,0$ manganu, 5»0-7,0$ chromu, ponizej 0,08$ fosforu, ponizej 0,07$ siarki, reszta zelazo, znamienne tym, ze zawiera w proce V h wagowych 0,5-1,5$ miedzi. PLThe subject of the invention is an abrasion-resistant alloy cast iron. Known is cast iron used for parts of machines and devices exposed to abrasion and mineral grains, Ni-Hard 4 grade, composition: 3.0 $ Si, 0.4-0.6 $ Mn, 5-6i5% Ni, 8.0-9.0 $ Cr below 0.4 $ MomaXf 0.06 $ SimaX and 0.06 $ P. Defect This cast iron is that this alloy contains expensive and deficient nickel.1 On the result of the research it was unexpectedly found that the high abrasion resistance corresponded to the above-mentioned cast iron had a new alloy cast iron, hereinafter referred to as chromium-manganese-herring cast iron # contains 1.8-3.3 $ carbon, 0.6-1.5 $ silicon, 1.0-3.0 $ manganese, 5.0-7.0 $ chromium, 0.5-1.5 $ Copper less than 0.08% of phosphorus, 0.07% of sulfur and the rest of iron * The cast iron of chromium o-manganese o-copper, according to the invention, is characterized by high resistance to abrasion, and in particular to blasting and erosion, and has good property of soybean foundry. Cast iron according to invented Azku can be used for castings of machinery, such as: lining of dust-air ducts in power industry, coke chutes and chutes, ash diffusers and other elements exposed to soiling with mineral grains. For example, cast iron according to the invention contains by weight: C - $ 2.8, Si - $ 1.0, Mn - $ 2.5, Cr - 595% 9 Cu - 1.3 $, P - 0.08 $, S - 0f06 $, Fe - the rest. Patent disclaimer Alloy cast iron, wear-resistant percentages by weight 1.8-3 $ carbon, 0.6-1.5 $ silicon, 1.0-3.0 $ manganese, 5 »0-7.0 $ chromium, less than 0.08 $ phosphorus, less than 0, 07% of sulfur, the rest is iron, characterized by the fact that it contains 0.5-1.5% by weight of copper in Vh process.
