Yintoni umahluko phakathi kweePile zeSheet zeSteel eziQokelelweyo ezishushu kunye neePile zeSheet zeSteel eziQokelelweyo ezibandayo

Kwicandelo lobunjineli bokwakha kunye nokwakha,Iinqwaba zePhepha leNsimbi(kudla ngokubizwa ngokuba yiukunqwabelanisa amashiti) kudala ibe yintsika yesiseko kwiiprojekthi ezifuna ukugcinwa komhlaba okuthembekileyo, ukumelana namanzi, kunye nenkxaso yesakhiwo—ukusuka ekuqinisweni konxweme lomlambo kunye nokukhuselwa konxweme ukuya ekumbiweni kwegumbi elingaphantsi komhlaba kunye nemiqobo yokwakha yexeshana. Nangona kunjalo, ayizizo zonke iiPile zeSteel Sheet ezidalwe zilingana: iinkqubo ezimbini eziphambili zokwenza—ukuqengqeleka okushushu kunye nokwenza ukubanda—zivelisa iimveliso ezahlukeneyo, iiPile zeSteel Sheet eziHot Rolled kunye neePile zeSteel Sheet eziCold Formed Rolled, nganye ineempawu ezizodwa ezenza zilungele usetyenziso oluthile. Ukuqonda umahluko wazo kubalulekile kwiinjineli, abakhi, kunye nabaphathi beeprojekthi ukuze benze izigqibo ezingabizi kakhulu neziqhutywa kukusebenza.

Iindidi ezimbini zeenkqubo zokwenziwa kweenqwaba zesinyithi

Iinkqubo zokuvelisa iintlobo ezimbini zokupakishwa kwamaphepha zibeka isiseko seempawu zazo ezahlukeneyo.Iinqwaba zePhepha zeNtsimbi eziSongiweyo ezishushuZenziwa ngokufudumeza iibhilethi zentsimbi ukuya kumaqondo obushushu aphezulu kakhulu (ngesiqhelo ngaphezulu kwe-1,000°C) ide isinyithi sibe lula ukunyibilika, size siyidlulise kuthotho lweerola ukuze siyibumbe kwiiprofayili ezidibeneyo (ezifana nohlobo lwe-U, uhlobo lwe-Z, okanye i-straight web) ezichaza ukunqwabelana kwamaphepha. Le nkqubo yobushushu obuphezulu ivumela iindawo ezinqamlezileyo ezintsonkothileyo neziqinileyo kwaye iqinisekisa uxinano lwezinto ezifanayo, njengoko ubushushu bususa uxinzelelo lwangaphakathi kwintsimbi. Ngokwahlukileyo koko,Iinqwaba zePhepha zeNsimbi eziQokelelweyo ezenziwe ngoBubandayozenziwe ngeekhoyili zentsimbi ezisikiweyo, ezisicaba ezenziwe ngeeprofayili ezidibeneyo kusetyenziswa iirola ezibandayo—akukho bushushu bugqithisileyo obusetyenziswayo ngexesha lokwenziwa. Inkqubo yokuqengqeleka okubandayo ixhomekeke ekuguquguqukeni kwentsimbi kubushushu begumbi, okwenza ukuba ilungele ukuvelisa iiprofayili ezikhaphukhaphu nezisemgangathweni ngakumbi, nangona inokungenisa uxinzelelo oluncinci lwangaphakathi olufuna ukucutshungulwa emva kokusetyenziswa (njengokutsalwa kwentsimbi) kwizicelo ezithile zomthwalo ophezulu.

Ukusebenza kunye neempawu zesakhiwo seentlobo ezimbini zeenqwaba zesinyithi

Ukusebenza kunye neempawu zesakhiwo zahlula ngakumbi ezi ntlobo zimbini. Iinqwaba zamaphepha ezigoqwe ngobushushu zinika amandla angaqhelekanga kunye nokuqina: isakhiwo sazo esigoqwe ngobushushu sinika amandla aphezulu okuxinana, amandla okuvelisa, kunye nokumelana nempembelelo, okwenza zibe zilungele iiprojekthi ezinzima, zexesha elide. Umzekelo, iinqwaba zamaphepha ezigoqwe ngobushushu zihlala zikhethwa kwiiprojekthi zokumba nzulu (apho iinqwaba zamaphepha kufuneka zimelane noxinzelelo olukhulu lomhlaba) okanye izakhiwo zokhuselo oluhlala luhleli zonxweme (ezivezwe kwimozulu enzima kunye nokugqwala kwamanzi olwandle). Xa ziphathwa ngengubo (njenge-epoxy okanye i-zinc), iinqwaba zamaphepha ezigoqwe ngobushushu nazo zibonelela ngokumelana nokugqwala okuphuculweyo, njengoko isakhiwo sezinto ezifanayo siqinisekisa ukunamathela okufanayo komaleko okhuselayo. Iinqwaba zamaphepha ezenziwe ngokubanda, kwelinye icala, zilula kwaye zibiza kancinci kwizicelo zemithwalo yexeshana okanye ephakathi. Ubunzima bazo obuphantsi benza lula ukuthuthwa kunye nokufakwa - kufuna izixhobo ezimbalwa kunye nomsebenzi - okwenza zibe zilungele inkxaso yokwakha yexeshana elifutshane, iindonga zezikhukula zexeshana, okanye iiprojekthi zesiseko sezindlu zokuhlala, apho amandla okuthwala umthwalo omkhulu angeyomfuneko iphambili. Nangona amandla azo engaphantsi kunezinye iindlela zazo ezitshixwayo, inkqubela phambili yakutshanje kubuchwepheshe bokwenza ubushushu (njengee-alloys zentsimbi ezinamandla aphezulu) iye yandisa ukusetyenziswa kwazo kwizakhiwo ezihlala ixesha elide.

Iindleko kunye nokufumaneka kweentlobo ezimbini zeenqwaba zesinyithi

Ixabiso kunye nokufumaneka kwazo zizinto ezibalulekileyo ekukhetheni phakathi kwezi zimbini. IiPili zeSteel Rolled Steel Sheet eziQokelelweyo eziBandayo ngokubanzi zinexabiso eliphantsi kwangaphambili, njengoko inkqubo yokuqengqeleka ebandayo igcina amandla, ifuna izixhobo ezingabalulekanga kangako, kwaye ivelisa inkunkuma encinci yezinto xa kuthelekiswa nokuqengqeleka okushushu. Zikwafumaneka ngokulula ngobukhulu obuqhelekileyo, kunye namaxesha amafutshane okukhokela kwimveliso—abalulekileyo kwiiprojekthi ezineshedyuli exineneyo. IiPili zeSteel Rolled Steel Sheet, ngokwahlukileyo, zineendleko eziphezulu zemveliso ngenxa yenkqubo yokufudumeza edinga amandla amaninzi kunye nesidingo soomatshini bokuqengqeleka abantsonkothileyo. Iiprofayili ezenziwe ngokwezifiso (ezenzelwe iimfuno zeprojekthi ezizodwa) nazo zongeza kwixabiso lazo kunye nexesha lokukhokela. Nangona kunjalo, ukuqina kwazo ixesha elide kudla ngokukhawulezisa utyalo-mali oluphezulu lokuqala: kwizakhiwo ezisisigxina, iiPili zeSteel Rolled Steel Sheet zifuna ukugcinwa okuncinci kwaye zinobomi obude benkonzo, nto leyo enciphisa iindleko zobomi ngokuhamba kwexesha.

Iingenelo zabo ezahlukeneyo

Ngamafutshane, zombini iinqwaba zamaphepha ezigoqwe ngobushushu kunye nezibandayo zidlala indima ebalulekileyo kulwakhiwo lwanamhlanje, kodwa umahluko wazo kwimveliso, ukusebenza, kunye neendleko zenza zifaneleke ngakumbi kwizicelo ezithile. Iinqwaba zamaphepha ezigoqwe ngobushushu zaziwa ngamandla azo, ukuqina, kunye nokufaneleka kwizicelo ezisisigxina nezinzima, ngelixa iinqwaba zamaphepha ezibandayo zibonelela ngokusebenza kakuhle kweendleko, ukulula kokufakwa, kunye nokuguquguquka, okwenza zifaneleke kwiiprojekthi zexeshana okanye eziphakathi. Njengoko imfuno yokwakha ezinzileyo nesebenzayo iqhubeka ikhula, iingcali zoshishino ziqikelela ukuba izinto ezintsha ziya kuqhubeka kuzo zombini iinkqubo, ukusuka kwii-alloys eziphuculweyo eziqinileyo ezibandayo ukuya kubuchwepheshe bokugoqwa ngobushushu obusebenzisa amandla ngakumbi, ukwandisa ngakumbi ukuguquguquka kweenqwaba zamaphepha kunye nezisombululo zeenqwaba zamaphepha kwihlabathi liphela.
