Bututun Layin X60, Kayan Injini Na

X60 Line Pipe, Surface zafi magani ya kasu kashi biyu, daya ne sinadaran zafi magani, daya ne surface quenching da tempering zafi magani, da taurin gwajin hanya ne kamar haka:

[1] Maganin zafi na sinadari na bututun X60
-- Maganin zafi na sinadarai shine sanya saman bututun bututun bututun X60 ya kutsa cikin nau'ikan nau'ikan zarra guda ɗaya ko da yawa, ta yadda za a canza sinadarai, tsari da kaddarorin saman bututun bututun na X60.Bayan quenching da ƙananan zafin jiki, saman bututun bututun X60 yana da tsayin daka, juriya da ƙarfin gajiya, kuma ainihin bututun bututun X60 yana da ƙarfi da ƙarfi.

-- Babban ma'auni na fasaha na maganin zafi na sinadarai X60 bututun su ne zurfin taurin Layer da taurin saman.Ya kamata a gwada zurfin Layer mai tauri ta vicker hardness tester.Auna nisa daga saman bututun X60 zuwa wurin da taurin ya ragu zuwa 50HRC.Wannan shi ne tasiri mai zurfi na tauraruwar zafin zafin sinadarai na X60 bututun bututun gwajin gwaji da zafin zafi da zafin jiyya na gano bututun bututun na X60, na iya amfani da ma'aunin taurin vickers, ma'aunin taurin dutsen dutse ko rockwell taurin gwaji don gwadawa, kawai kauri na nitriding mai kauri mai kauri, gabaɗaya bai wuce 0.7 mm ba, sannan ba zai iya ƙara yin amfani da ma'aunin taurin rockwell ba, ana iya amfani da mai gwajin Microhardness.

[2] X60 bututun saman quenching da yanayin zafi mai zafi
-- quenching surface da yanayin zafi yawanci ana yin su ta hanyar dumama shigar da wuta ko dumama harshen wuta.Babban ma'auni na fasaha sune taurin saman, taurin gida da ingantaccen zurfin Layer.Ana iya amfani da ma'aunin taurin Vickers don gwajin taurin, rockwell ko saman Rockwell hardness tester.Zaɓin ƙarfin gwaji (ma'auni) yana da alaƙa da zurfin tasiri mai ƙarfi mai ƙarfi da taurin saman bututun X60.Akwai nau'ikan mita taurin kai.

Vickers hardness tester wata hanya ce mai mahimmanci don gwada taurin zafin zafi da aka yi da bututun bututun X60.Yana iya amfani da 0.5 ~ 100kg gwajin ƙarfi don gwada saman taurare Layer matsayin bakin ciki kamar 0.05mm.Daidaiton sa shine mafi girma, kuma yana iya bambance ɗan bambanci na taurin saman zafi da aka bi da bututun bututun X60.Bugu da kari, zurfin da tasiri hardening Layer kuma auna ta vickers hardness tester, don haka shi wajibi ne don ba da wani Vickers taurin gwajin ga raka'a cewa gudanar da surface zafi jiyya ko amfani da babban adadin surface zafi jiyya workpiece.

-- Surface Rockwell hardness tester shima ya dace sosai don gwada taurin bututun bututun bututun X60.Akwai ma'auni guda uku don gwajin taurin dutsen Rockwell don zaɓar daga.Za a iya gwada nau'ikan layukan X60 masu taurare tare da ingantaccen zurfin taurin sama da 0.1mm.Kodayake madaidaicin majinin taurin dutsen Rockwell bai kai matsayin mai gwada taurin vickers ba, yana iya biyan buƙatu azaman hanyar gwaji don gudanarwa mai inganci da tabbatar da daidaito a cikin tsire-tsire masu zafi.Haka kuma, shi ma yana da halaye na sauki aiki, m amfani, low price, m auna, da kuma iya kai tsaye karanta taurin darajar, da dai sauransu Surface Rockwell taurin magwajin za a iya amfani da tsari na surface zafi magani X60 bututu mai sauri da kuma wadanda ba. gwaji mai lalacewa.Wannan yana da matukar mahimmanci ga sarrafa bututun X60 da masana'antar kera injuna.

-- Hakanan za'a iya amfani da ma'aunin taurin Rockwell lokacin da saman taurare ya yi kauri.Lokacin da kauri na taurare Layer na zafi magani ne 0.4 ~ 0.8mm, HRA sikelin za a iya amfani da, lokacin da kauri na taurare Layer ne fiye da 0.8mm, HRC sikelin za a iya amfani.

-- Vickers, Rockwell da Surface Rockwell ƙimar taurin ƙima za a iya canzawa cikin sauƙi zuwa daidaitattun ƙima, zane ko ƙimar taurin mai amfani da ake buƙata.An ba da madaidaitan allunan juzu'i a cikin ma'auni na duniya ISO, ma'aunin ASTM na Amurka da ma'aunin GB/T na Sinanci.

[3] Maganin zafin gida
-- Idan ana buƙatar taurin gida na sassa ya zama babba, ana iya yin maganin zafi na gida ta hanyar dumama shigar da wasu hanyoyin.Irin waɗannan bututun bututun na X60 yawanci suna buƙatar alamar wurin maganin zafi na gida da ƙimar taurin gida akan zane.Za a gudanar da gwajin taurin bututun X60 a wurin da aka keɓe.Kayan aikin gwajin taurin na iya amfani da majinin taurin Rockwell, gwada ƙimar taurin HRC, kamar taurin maganin zafi mara zurfi, na iya amfani da gwajin taurin Rockwell, gwada ƙimar taurin HRN.
