Bakin Karfe Square Rectangle Pipe
Bakin Karfe Square Tube nau'i ne na bututun.Akwai nau'ikan bututu mai zagaye, murabba'i, rectangular, hexagonal da nau'ikan bututun ruwa a cikin nau'ikan bakin karfe. Akwai nau'ikan bakin karfe 304, 316 na austenitic bakin karfe wadanda galibi ana amfani da su a masana'antu.Haka kuma akwai wasu nau'ikan bututun bakin karfe irin su duplex, ferritic, martensitic da kayan ƙarfe na gami.
Bakin karfe square tube da rectangular tube yawanci ake magana a kai a matsayin tube karfe ko tsarin tubing.Ana kuma nusar da waɗannan a matsayin sashe mai zurfi ko HSS a takaice.An yi amfani da shi don dalilai na tsari, bututu mai murabba'i, bututun rectangular, I biam, da sauransu, ana iya siyan su a cikin nau'ikan ƙarfe da gami da yawa.Kera bututun murabba'i iri ɗaya ne da tsarin masana'anta na bututu amma samfurin yana shiga cikin jerin matakan siffatawa, yana saduwa da ƙayyadaddun murabba'in sa na ƙarshe.
Sashin giciye na murabba'i na bututu yana ba da kyakkyawan ƙarfin geometric.Don haka ana amfani da bututun a cikin aikace-aikacen ƙarfi mai ƙarfi.Akwai sabis na matsi da zafin jiki kamar na'urorin musayar zafi waɗanda ke amfani da bututun.Bututun murabba'in 316 ss yana da ƙarfi kuma yana jure lalata.Kayan 316 yana da chromium, nickel da molybdenum a cikin abun da ke ciki.Wannan haɗin yana ba da damar haɓaka juriya na lalata tare da ƙaramin ƙarfin 215MPa mafi ƙarancin ƙarfin 505MPa ƙaramin ƙarfi.Hakanan bututun na iya aiki a ƙarƙashin yanayin zafi har zuwa digiri 870 ma'aunin Celsius.SS Square Welded Tube yana amfani da lokuta a cikin mai da gas, man fetur, petrochemical, gine-gine da kuma a aikace-aikacen tsarin.Akwai mafi girma maki kamar SS317 Square Tubes waɗanda aka yi da 317 matakin abu wanda yana da 517MPa mafi ƙarancin ƙarfi.Yana da amfani a aikace-aikace masu ƙarfi masu ƙarfi.Ana amfani da ASTM A270 Seamless Square Tube a cikin babban matsin lamba, sabis na zafin jiki da kuma sabis na lalata gabaɗayan ma.
Bakin Karfe maras sumul Square Tubing, The Production Process
Shirye-shiryen karfe na zagaye → dumama → zafi mai jujjuyawa → yankan kai → pickling → polishing → lubrication → tsarin mirgina sanyi → ragewa → maganin zafi → daidaitawa → yankan bututu → pickling → gama samfurin dubawa.
Bakin Karfe Sulumi Square Tubing , Performance Analysis
Ƙarfe na iya amsawa tare da oxygen a cikin yanayi don samar da fim din oxide a saman.Iron oxide da aka samu akan ƙarfe na carbon na yau da kullun zai ci gaba da yin oxidize, yana faɗaɗa lalata kuma a ƙarshe ya samar da ramuka.Ana iya yin wannan ta amfani da fenti ko ƙoshin ƙarfe mai jurewa da iskar oxygen don kare farfajiyar ƙarfe na carbon, amma wannan suturar fim ne kawai.Idan rufin ya lalace, karfen da ke ƙarƙashinsa ya sake yin tsatsa.Ko bututun bakin karfe ya lalace yana da alaƙa da abun ciki na chromium a cikin ƙarfe.Lokacin da chromium abun ciki a cikin karfe ya kai 12%, saman bakin karfe tube haifar da Layer na passivation da m chromium arziki oxide don kare farfajiya da kuma hana kara reoxidation.Wannan Layer Oxide yana da siriri matuƙa, ta inda za a iya ganin ƙyalli na zahiri na saman ƙarfe, wanda ke ba da bakin ƙarfe wani wuri na musamman.Idan fim ɗin chromium ya lalace sau ɗaya, chromium a cikin ƙarfe da oxygen a cikin yanayi don sake farfado da fim ɗin wucewa, ci gaba da taka rawar kariya.A wasu wurare na musamman, bakin karfe zai kuma bayyana wasu lalatawar gida da gazawa, amma bakin karfe da carbon karfe sun bambanta, ba za su bayyana lalata da gazawa ba, don haka izinin lalata ga bututun bakin karfe ba shi da ma'ana.
