Metallurgical Properties na kayan

Ana samar da bututun welded mai tsayin daka na baka daga faranti na karfe, yayin da ake samar da bututu masu walda da karkace daga coils masu zafi.The zafi-birgima tsiri naúrar mirgina tsari yana da dama abũbuwan amfãni, kuma yana da metallurgical tsari damar samun samar da high quality bututu line karfe.Misali, tsayayyen fitarwa yana sanye take da tsarin sanyaya ruwa don hanzarta sanyaya, wanda ke ba da damar yin amfani da ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙarfi don cimma ma'aunin ƙarfi na musamman da ƙarancin zafin jiki, don haka haɓaka weldability na ƙarfe.Duk da haka, wannan tsarin ba ya nan a masana'antar samar da takardar karafa.Abubuwan da ke cikin gami (madaidaicin carbon) na coils sau da yawa suna ƙasa da na nau'ikan nau'ikan nau'ikan faranti na ƙarfe, wanda kuma yana haɓaka haɓakar bututun welded na karkace.

More muhimmanci a lura shi ne, saboda karkace welded bututu nada mirgina shugabanci ba perpendicular zuwa shugabanci na karfe bututu axis (sa tsunkule bayani dogara a kan karkace kwana na karfe bututu), yayin da madaidaiciya kabu karfe bututu karfe farantin mirgina. shugabanci perpendicular zuwa shugabanci na karfe bututu axis, kuma ta haka ne, karkace welded bututu abu ne mafi alhẽri daga madaidaiciya kabu karfe bututu crack juriya.

Tsarin walda

Daga tsarin walda, karkace bututu da madaidaiciyar kabu karfe bututun walda hanya iri ɗaya ce, amma madaidaiciyar bututu mai walƙiya ba makawa za ta sami walƙiya mai yawa, don haka yiwuwar lahanin walda yana ƙaruwa sosai, da ragowar damuwa na walda. a ding weld ya fi girma, ƙarfe na walda sau da yawa yana cikin yanayin damuwa ta hanyoyi uku, yana ƙara yiwuwar fashewa.

Haka kuma, bisa ga submerged baka waldi tsari, kowane weld ya kamata a a baka farawa da baka kashewa, amma kowane madaidaiciya kabu welded bututu a cikin welded annular kabu, ba zai iya cimma yanayin, don haka za a iya samun karin walda lahani a baka. kashewa.
