Ukucwila Okujulile Kwebanga Lensimbi: Umehluko Obalulekile Phakathi kwe-A36, A572, 1018 kanye ne-4140

Ukukhetha izinga lensimbi elifanele kuyisinqumo esincane esinemiphumela emikhulu. Izinto ezingalungile zingaholela ekuqhekekeni kwe-welding, ukuguguleka kwangaphambi kwesikhathi, noma ukweqisa kwezindleko okungadingekile. Khetha kahle, futhi izakhiwo zakho nezingxenye zakho zizosebenza ngokuthembekile, impilo yenkonzo ende ngisho noma zisetshenziswa njalo.

At Iqembu Lensimbi Yasebukhosini, sigcina uhlu olujulile lwezinhlobo zensimbi ezakhiwe kahle nezisetshenziswa kakhulu, futhi ithimba lethu lokuthengisa lobuchwepheshe lisiza amakhasimende ukuthi anciphise inketho engcono kakhulu yomsebenzi ngamunye. Kulo mhlahlandlela, sihlukanisa izinhlobo ezine ezivame kakhulu ozohlangana nazo ekukhiqizeni nasekukhiqizweni—okuzihlukanisayo, lapho zisebenza khona kangcono, nokuthi yimiphi imikhiqizo esiyigcinayo ngaphakathi.

I-ASTM A36: Ihhashi Elisebenzayo Elifanele Umsebenzi Wokwakha Ojwayelekile

I-ASTM A36iyizinga lensimbi yesakhiwo esetshenziswa kakhulu eNyakatho Melika, futhi ngesizathu esihle. Leli zinga le-carbon ephansi linikeza amandla okukhiqiza okungenani angu-36 ksi, ngamandla okudonsa asukela ku-58 kuya ku-80 ksi—amandla amaningi kumaphrojekthi amaningi okwakha nokukhiqiza ajwayelekile, kuyilapho ehlala ebekezelela kakhulu ukushisela nokwakha.

Izakhiwo ezibalulekile

Okuqukethwe kwekhabhoni: 0.25–0.29%
Amandla okukhiqiza amancane: 36 ksi
Amandla okunamathela: 58–80 ksi
Ukushisela okuhle kakhulu; akukho ukushisa okudingekayo kuzinhlelo zokusebenza eziningi
Kulula ukubhoboza, ukusaha, ukubhoboza, nokusika ngemishini ejwayelekile yesitolo

I-A36 iyisinqumo esizenzakalelayo samafreyimu okwakha, izingxenye zamabhuloho, izisekelo zemishini, amafreyimu e-trailer, amabakaki, ama-gussets, kanye cishe nayo yonke imisebenzi yokwakhiwa kwesakhiwo evamile.

KwaRoyal Steel Group, i-A36 iyatholakala kuwo wonke umugqa wethu womkhiqizo ogcwele ogoqwe ngokushisa: amapuleti, amashidi, imigoqo eyisicaba, ama-engeli, iziteshi, imigoqo ye-I, imigoqo ye-flange ebanzi, kanye nemigoqo eyindilinga.

I-ASTM A572 Ibanga 50: Amandla Aphezulu Okuklama Okulula Nokusebenza Kakhulu

Ibanga lama-50 le-ASTM A572iyinsimbi yesakhiwo enamandla aphezulu e-low-alloy (HSLA) eyakhelwe imithwalo esindayo kanye nemiklamo ezwela isisindo. Njengoba inamandla amancane okukhiqiza angama-50 ksi, inamandla cishe angama-39% kune-A36, okusho ukuthi onjiniyela bangasebenzisa izingxenye ezincane nezilula ukuthwala umthwalo ofanayo. Kumaphrojekthi amakhulu, lokhu kuvame ukunciphisa amathoni ezinto zokwakha, kunciphisa isisindo sokuhlanganiswa okuphelele, futhi kunciphisa izindleko eziphelele.

Izakhiwo ezibalulekile

Okuqukethwe okuphezulu kwekhabhoni: 0.23%
Amandla okukhiqiza amancane: 50 ksi
Amandla amancane okudonsa: 65 ksi
Ukushibilika okunamandla, okuqhathaniswa ne-A36 yezinqubo eziningi zokukhiqiza
Imikhiqizo eminingi yamapuleti kanye nephrofayili inesitifiketi se-A36/A572 Grade 50 esikabili

Kuyindlela ekhethwayo yomsebenzi onzima wesakhiwo, ukwakhiwa kwamabhuloho, uzimele ophakeme, ama-crane boom, izingxenye zemishini esindayo, imibhoshongo yokudlulisa, nanoma yimuphi umsebenzi lapho ukonga isisindo kuletha khona inzuzo yangempela.

Sigcina i-A572 Grade 50 ngamapuleti, imisebe ye-I, imisebe ye-flange ebanzi, iziteshi, nama-engeli.

I-AISI 1018: Ibanga Elithandwayo Lezingxenye Ezifakwe Ngomshini Ezibandayo

I-AISI/SAE 1018 iyinsimbi eguquguqukayo ephansi yekhabhoni evame ukunikezwa njengesitokwe sebha esidonswa ngokubandayo. Iyintandokazi yesitolo yezingxenye ezifakwe ngomshini nezihlanganisiwe, ngenxa yobuchwepheshe bayo obuqhubekayo kanye nokuphela kwayo okubushelelezi, okufanayo kusuka endaweni yokugaya.

Izakhiwo ezibalulekile

Okuqukethwe kwekhabhoni: 0.15–0.20%
Amandla okukhiqiza adonswa ngokubandayo: ~54 ksi
Amandla okudonswa okudonswa kubanda: ~64 ksi
Ukusebenza kahle kakhulu kwemishini kanye nokushibilika
Isabela ekuqineni kwekesi endaweni engagugi kanye nomgogodla oqinile, othambile

I-1018 isetshenziswa kabanzi kuma-shaft, ama-pin, ama-studs, ama-spacer, ama-bushings, ama-fixtures, kanye nezingxenye zemishini ezisetshenziswa kabanzi lapho ukulawula okuqinile kanye nokuqeda okuhlanzekile kubalulekile.

Impahla yethu ifaka phakathi amabha ayi-1018 ayindilinga, ayisicaba, kanye namabha ayisikwele adonswe ngokubandayo, kanye namabha ayisikwele aqediwe ngokubandayo.

I-AISI 4140: Insimbi Yengxube Yezicelo Ezicindezela Kakhulu Nezinzima

I-AISI/SAE 4140 iyinsimbi ye-chromium-molybdenum (chromoly) eyenziwe ngezinsimbi ezibona ukucindezeleka okukhulu, ukushayisana, noma ukuguguleka. Inikeza amandla nokuqina okukhulu kakhulu kunezinsimbi zekhabhoni ezijwayelekile ezifana ne-1018, futhi isabela kahle kakhulu ekwelashweni kokushisa kokuqina okuphezulu ngenkathi igcina ukuqina kwengaphakathi.

Izakhiwo ezibalulekile

Okuqukethwe kwekhabhoni: 0.38–0.43%
Amandla okukhiqiza ahlanganisiwe: ~ 60 ksi (ukwelashwa okuphezulu kakhulu ngemva kokushisa)
Amandla okunamathela ahlanganisiwe: ~95 ksi (angadlula i-150 ksi ngemuva kokwelashwa ngokushisa)
Ukumelana okuhle nokukhathala kanye namandla omthelela
Ingashiselwa kuphela ngokushisa okulawulwayo kanye nokwelashwa kokushisa ngemva kokushiselwa ukuze kuvinjelwe ukuqhekeka

Ukusetshenziswa okuvamile kufaka phakathi ama-axle, imiphini enemithwalo ephezulu, amagiya, amabhawodi anamandla aphezulu, ama-collet, amasilinda e-hydraulic, amathuluzi, izibambo zomshini wokufafaza, nezinye izingxenye zesakhiwo ezicindezela kakhulu.

I-4140 itholakala kakhulu njengebha eyindilinga. Xhumana nethimba lethu ukuze uthole isilinganiso esenziwe ngokwezifiso ngosayizi othile kanye nezidingo zobude obufanele.

Indlela Yokukhetha Ibanga Elifanele Lephrojekthi Yakho

Ukunciphisa izinga lensimbi elihle kakhulu kuholela emibuzweni emithathu ewusizo:

Ingakanani umthwalo ozothwalwa yingxenye?Emisebenzini ejwayelekile yokwakha, i-A36 ihlanganisa izidingo eziningi zansuku zonke. Khuphukela ku-A572 Grade 50 ukuze uthole imithwalo esindayo, isikhathi eside, noma amaphrojekthi lapho ukunciphisa isisindo sonke kuyinto eza kuqala.

Uzodinga imishini enembile?Ezingxenyeni ezidinga ukuphendulwa, ukugaya, ukubhoboza, noma ukubekezelelana okuqinile, insimbi edonswa ngokubandayo engu-1018 iletha imiphumela ehlanzekile nehambisanayo. Ezingxenyeni ezisebenza kahle kakhulu ngaphansi kokucindezeleka okukhulu, insimbi ye-alloy engu-4140 ingcono kakhulu.

Uzojoyina kanjani izingxenye?I-A36 kanye ne-1018 zishibilika kalula ngezinqubo ezijwayelekile zesitolo, akukho ukushisa okudingekayo. I-A572 Grade 50 isebenza cishe ngendlela efanayo yokusebenza. I-4140 idinga ukushibilika kusengaphambili ngokucophelela kanye nokwelashwa kokushisa ngemva kokushibilika ukuze kugwenywe ukuqhekeka—hlela inqubo yakho yokukhiqiza ngokufanele.

Uma ungakaqiniseki ukuthi yiliphi ibanga elifanelana nemininingwane yakho, ithimba lethu lokuthengisa lisingatha imibuzo yokukhetha ibanga nsuku zonke.→Sithumelele imininingwane yephrojekthi yakho, futhi sizokukhombisa inketho engabizi kakhulu nehambisana nokusebenza kahle..

Ukusekelwa Kokucubungula Nokuthola Izinto Kwangaphakathi

Asihlinzeki ngezinto zensimbi ezingavuthiwe kuphela kodwa futhi nezinsizakalo eziphelele zokucubungula ngaphakathi, siletha izinto eziqediwe ezilungele umugqa wakho wokukhiqiza. Imikhiqizo yethu yensimbi egcwele ingasikwa, yakhiwe, noma isetshenziswe ngomshini ngokwezidingo zakho, kufaka phakathi ukusika nge-laser kwezingxenye zepuleti elinembile, ukusika nge-plasma okunencazelo ephezulu kwamapuleti aqinile, ukugunda ukuze kunqunywe okuqondile, ukugoba nokwakheka kwe-CNC, kanye nokusika ngokunemba kwama-bar namaphrofayili.

Uma ufuna ukucutshungulwa ngokwezifiso noma ama-oda amaningi, ungathumela isicelo sesilinganiso ngqo ngewebhusayithi yethu noma uxhumane nethimba lethu ukuthola iseluleko sochwepheshe mayelana nokukhethwa kwamabanga kanye namalungiselelo okulethwa. Sinikeza ukuthunyelwa komhlaba wonke ukuqinisekisa ukuthi iphrojekthi yakho ihlala ngesikhathi.
