Duplex Karfe Simintin gyare-gyare - Cikakken Jagora

Duplex karfe, kuma aka sani da duplex bakin karfe, wani nau'i ne na musamman wanda ya haɗu da halaye masu amfani na duka biyu austenitic da kuma ferritic karfe. Sunansa ya samo asali ne daga microstructure guda biyu, wanda ya ƙunshi cakuda austenite da matakan ferrite. Duplex karfe simintin gyaran kafa ya ƙunshi daidaitaccen iko na wannan microstructure don cimma ingantattun kaddarorin inji, juriya na lalata, da weldability. Wannan ingantaccen jagorar ya ƙunshi mahimman abubuwan da ke tattare da simintin ƙarfe na duplex, daga zaɓin kayan abu zuwa dabarun yin simintin da la'akari bayan aiwatarwa.

1. Zabin Abu:

Duplex karfe simintin fara tare da taka tsantsan zaɓi na dace sa na duplex karfe. Akwai maki da yawa akwai, kowanne an inganta shi don takamaiman aikace-aikace. Maki gama gari sun haɗa da Saukewa: UNS31803 (wanda aka fi sani da 2205), Saukewa: UNS32205, da kuma UNS S32750. Waɗannan maki sun bambanta a cikin abun da ke ciki, kayan aikin injiniya, da juriya na lalata. Misali, UNS S31803 yana da madaidaitan austenite-ferrite microstructure, yana mai da shi dacewa da wurare masu lalata da yawa. UNS S32750, a gefe guda, babban ƙarfe ne mai duplex tare da mafi girma chromium da kuma molybdenum abun ciki, samar da ingantaccen juriya na lalata.

2. Dabarun Yin Zama:

Ana iya yin simintin ƙarfe na Duplex ta amfani da dabaru daban-daban, gami da simintin yashi, simintin saka hannun jari, da jefar simintin. Zaɓin fasaha na simintin gyare-gyare ya dogara da siffar da ake so, girman, da wuyar yin simintin ƙarshe. Yin simintin yashi ya dace da simintin gyare-gyare mafi girma da kuma hadaddun, yayin da simintin zuba jari yana ba da cikakkun bayanai da filaye masu santsi. Die simintin yawanci ana amfani da shi don ƙarami, babban aikin samarwa.

A lokacin aikin simintin gyare-gyare, yana da mahimmanci don kula da tsananin zafin jiki. Dole ne a zubar da narkakken ƙarfe a mafi kyawun zafin jiki don gujewa rashin ƙarfi, haɗawa, ko wasu lahani na simintin. Bugu da ƙari, dole ne a ƙirƙira ƙirar simintin don haɓaka ƙimar sanyaya iri ɗaya, hana damuwa mai zafi da warping.

3. Sarrafa Ƙirar Ƙira:

Makullin cimma abubuwan da ake buƙata na injina a cikin simintin ƙarfe na duplex ɗin ƙarfe shine daidaitaccen iko na ƙananan tsarin. Dole ne a daidaita matakan Austenite da ferrite don haɓaka ƙarfi, ductility, da tauri. Ana iya samun wannan ma'auni ta hanyar sarrafa yanayin sanyaya, kula da zafi, da ƙari na gami.

Maganin zafi yana taka muhimmiyar rawa wajen sarrafa microstructure. Annealing, daidaitawa, da quenching sune hanyoyin magance zafi na yau da kullun da ake amfani da su don daidaita ma'auni na lokaci da haɓaka kaddarorin inji na simintin ƙarfe na duplex.

4. La'akarin Bayan-Aiki:

Da zarar an kammala simintin gyare-gyare, za ta ɗauki matakai daban-daban na bayan aiwatarwa don cimma abin da ake so na ƙarshe. Waɗannan matakan sun haɗa da injina, niƙa, fashewar fashewar abubuwa, da wuce gona da iri. Ana amfani da machining don cire abubuwan da suka wuce gona da iri kuma cimma siffar da ake so da girma. Ana amfani da niƙa da harbe-harbe don sassauta saman da cire duk wani lahani. Passivation magani ne na sinadarai wanda ke haɓaka juriya na lalata simintin ta hanyar samar da Layer oxide mai kariya a saman.

5. Tabbatar da Inganci:

Tabbacin inganci shine mafi mahimmanci a cikin simintin ƙarfe na duplex. Ana amfani da hanyoyin gwaji marasa lalacewa kamar X-ray, ultrasonic, da duban ɓarna na maganadisu don gano kowane lahani na ciki ko lahani. Hakanan ana yin duban gani da duban ƙima don tabbatar da simintin ya cika ƙayyadaddun ka'idoji da buƙatu.

Kammalawa

A ƙarshe, simintin ƙarfe mai duplex tsari ne mai rikitarwa wanda ke buƙatar kulawa sosai ga daki-daki da tsananin riko da mafi kyawun ayyuka. Ta hanyar zaɓar madaidaicin matakin ƙarfe na duplex a hankali, ta amfani da dabarar simintin simintin da ta dace, sarrafa microstructure, da yin cikakken aiki bayan sarrafawa da tabbatar da inganci, yana yiwuwa a samar da simintin ƙarfe mai inganci mai inganci wanda ya dace da mafi tsananin buƙatu.

Na gode da karanta labarinmu kuma muna fatan zai iya taimaka muku don samun kyakkyawar fahimta game da simintin ƙarfe na duplex. Idan kana neman duplex bakin karfe masu kaya akan layi yanzu, da fatan a yi shakka a tuntuɓi Sino Bakin Karfe.
