Lim Daim duab peb sab Yoke Phaj feem ntau yog siv nyob rau hauv cov khoom siv hluav taws xob, feem ntau yog siv los sau, faib, thiab xa cov nro ntawm ntau cov hlua hluav taws xob thiab cov khoom siv hluav taws xob. Hauv kev ua haujlwm tiag tiag, lub phaj yoke tiv taus qhov nro ntawm tus neeg xyuas pib, cua- ua rau muaj kev vibration, icing loads, kub ntxhov siab, xob laim ntaus, thiab ntau hom corrosion los ntawm huab cua, ntsev tsuag, thiab muaj kuab paug. Nws lub zog muaj zog, kev ruaj ntseg txhua yam, thiab kev tiv thaiv corrosion ncaj qha txiav txim siab ua haujlwm nyab xeeb ntawm tag nrho cov kab sib kis. Lub hauv paus thiab qhov yuav tsum tau ua ua ntej rau cov khoom no yog nyob rau hauv kev xaiv cov khoom siv thaum lub sijhawm tsim khoom.
Kev xaiv cov khoom siv tsis yog tsuas yog hais txog kev xaiv ib hom hlau, tab sis kev txiav txim siab raws li kev txiav txim siab ntawm ntau yam, suav nrog kev ntsuas hluav taws xob, kev tsim nro, kev ua haujlwm ib puag ncig, kev siv thev naus laus zis, kev tiv thaiv corrosion, kev tswj hwm tus nqi, thiab cov qauv hauv tsev thiab thoob ntiaj teb thiab cov qauv tshwj xeeb. Cov tshuaj muaj pes tsawg leeg, txhua yam khoom, weldability, txias ua hauj lwm zog, kub -dip galvanizing adaptability, corrosion kuj, thiab qaug zog zog ntawm cov khoom tag nrho ncaj qha cuam tshuam rau cov khoom tiav, kev pab cuam lub neej, thiab kev nyab xeeb margin ntawm Strain Daim duab peb sab Yoke phaj.
Thaum xaiv cov ntaub ntawv rau Strain Triangle Yoke Plate, cov cim qhia kev ua haujlwm tseem ceeb uas yuav tsum tau ntsib yog feem ntau txiav txim siab los ntawm cov hauv qab no:
Lub zog siab txaus: suav nrog lub zog tawm los thiab lub zog tensile, kom tsis txhob muaj cov yas deformation los yog tawg nyob rau hauv qhov siab tshaj plaws tsim load;
Zoo plasticity thiab toughness: tiv thaiv nkig tawg nyob rau hauv qis kub, cuam tshuam, thiab kev co;
Kev qaug zog zoo heev: tiv taus ntev - lub sij hawm cua vibration thiab alternating loads, tsis txhob qaug zog tawg propagation tsis ua hauj lwm;
Kev ua tau zoo heev: suav nrog kev hloov kho rau kev txiav, xuas nrig ntaus, khoov, vuam, ncaj, kub-dip galvanizing, thiab lwm yam;
Kev tiv thaiv corrosion: ua tau raws li kub-dip galvanizing yuav tsum, nrog ib txheej zinc txheej, muaj zog adhesion, thiab tsis tiav galvanizing, brittleness, los yog pitting;
Kev ruaj ntseg tshuaj muaj pes tsawg leeg: cov khoom tsis zoo xws li carbon, sulfur, thiab phosphorus raug tswj nyob rau hauv cov txheej txheem kom ntseeg tau tias vuam thiab galvanizing zoo.
Raws li kev xyaum ua lub sij hawm ntev hauv kev tsim cov kab sib txuas, cov ntaub ntawv ntawm Strain Triangle Yoke Phaj feem ntau muab faib ua plaub pawg: carbon structural steel, low alloy high-strength structural steel, weather-resistant structural steel, thiab high-strength alloy structural steel.
Carbon structural steel yog tam sim no feem ntau siv thiab cov khoom siv tseem ceeb rau strain daim duab peb sab yoke daim hlau nyob rau hauv nruab nrab thiab qis voltage kis kab ob leeg hauv tsev thiab thoob ntiaj teb. Nws boasts qhov zoo xws li tus nqi qis, zoo machinability, ruaj khov vuam, thiab muaj zog adaptability rau galvanizing. Cov ntsiab lus carbon yog nruab nrab, feem ntau Tsawg dua los yog sib npaug li 0.20%, kom ntseeg tau tias plasticity, toughness, thiab weldability. Ua phem impurities xws li sulfur thiab phosphorus yog tswj nruj me ntsis kom lav cov khoom purity. Nws tsis muaj cov khoom tseem ceeb alloying, muab tus nqi siab heev -kev ua tau zoo. Lub zog tensile yog 370-500 MPa, lub zog tawm los yog 235 MPa thiab 345 MPa, elongation tom qab tawg yog ntau dua lossis sib npaug li 21%, thiab kev cuam tshuam lub zog ua tau raws li qhov yuav tsum tau muaj rau kev cuam tshuam hauv chav sov.
Tsawg- alloy siab- lub zog cov qauv hlau: Raws li qis- cov pa roj carbon steel, qhov sib ntxiv ntawm cov khoom me me ntawm cov ntsiab lus alloying (Mn, Si, Nb, V, Ti, thiab lwm yam) ua kom lub zog zoo thaum tuav cov yas zoo, toughness, thiab cov txheej txheem ua tau zoo. Cov ntsiab lus tsis tshua muaj cov pa roj carbon monoxide ua kom muaj kev sib tw thiab tawv; qhov sib ntxiv ntawm cov kab alloying ntsiab refines cov nplej, txhim kho lub zog thiab qis - kub toughness; stricter sulfur thiab phosphorus tswj txhim khu kev qaug zog thiab tawg tsis kam, ua rau nws haum rau siab -lub zog, lub teeb yuag qauv tsim. Yield zog 355MPa–460MPa, tensile zog 470MPa–650MPa, thiab zoo heev tsawg-kub tej yam toughness, haum rau siv nyob rau hauv ib puag ncig xws li -20℃mus rau -40 degree.
Weathering structural steel: Los ntawm kev ntxiv cov ntsiab lus xws li Cu, P, Cr, thiab Ni, ib txheej tuab thiab ruaj khov tiv thaiv xeb yog tsim nyob rau hauv cov huab cua, txo tus nqi corrosion. Nws yog qhov tshwj xeeb tshaj yog tsim rau cov cheeb tsam hnyav xws li ntug dej hiav txwv ntsev tsuag, muaj kuab paug, cov av noo siab, thiab cov kua qaub los nag. Muaj corrosion- tiv taus cov ntsiab lus xws li tooj liab, chromium, npib tsib xee, thiab phosphorus, ib qho kev ruaj khov passivation zaj duab xis tuaj yeem tsim sai sai rau saum npoo, tiv thaiv corrosion ntawm sab hauv. Nws cov ntsiab lus carbon tsawg ua kom muaj kev sib raug zoo nrog kev vuam thiab galvanizing. Nws yog qhov tsim nyog rau thaj chaw ntug dej hiav txwv, Islands tuaj, thaj chaw tshuaj tsuag ntsev, thaj chaw muaj tshuaj lom neeg, thaj chaw muaj kev lag luam, thiab sulfide- thaj chaw muaj kuab paug.
High-strength alloy structural steel: Yog hais tias lub Strain Daim duab peb sab Yoke phaj yog siv nyob rau hauv ntxiv -ntev ncua los yog super- hnyav load kab, siab - lub zog alloy structural steel yuav tsum tau xaiv. Nws muaj cov ntsiab lus alloying xws li Cr, Mo, thiab Mn, muaj cov khoom siv kho tshuab zoo heev, zoo hardenability, thiab sab saum toj - qib zog, toughness, thiab qaug zog ua haujlwm.
