I-China Ukusetyenziswa kwezorhwebo ipleyiti yentsimbi eshushu eqengqeleyo eshushu eqengqelekayo ePickled yentsimbi Umenzi kunye noMboneleli | Ruiyi

I-Hot-rolled steel yintsimbi eye yafudunyezwa kwaye yaqengqeleka kwiqondo lokushisa eliphezulu. Amandla ayo awaphezulu kakhulu, kodwa anele ukusetyenziswa kwethu. Iplastiki yayo kunye ne-weldability ingcono, ngoko sihlala siyisebenzisa; intsimbi eqengqelekayo ebandayo yintsimbi eqhelekileyo eqengqelekayo eshushu. Intsimbi etsalwe ngamandla kwaye idlula inqanaba lokuqina lobunzima, inamandla amakhulu, kodwa inzima kwaye i-weldability, kwaye inzima kwaye i-brittle. I-Hot rolling icutshungulwa kwiqondo lokushisa eliphezulu. Ukuqengqeleka okushushu kuthetha ukuba izinto kufuneka zifudunyezwe ngexesha okanye ngaphambi kokuqengqeleka kwentsimbi. Ngokuqhelekileyo, ishushu ngaphezu kobushushu bokubuyisela kwakhona ngaphambi kokuqengqeleka.

1. Intsimbi eyenziwe ngokubanda epholileyo ivumela i-buckling yendawo yecandelo, ukwenzela ukuba umthamo wokuthwala emva kwe-buckling ye-bar ingasetyenziswa ngokupheleleyo; ngelixa icandelo elishushu-eliqengqelekayo lingavumeli ukubhaqwa kwendawo yecandelo.

2. Izizathu zoxinzelelo olushiyekileyo lwentsimbi eshushu kunye nentsimbi epholileyo zihluke, ngoko ke ukusabalalisa kwi-cross-section kukwahluke kakhulu. Ukusabalalisa uxinzelelo olushiyekileyo kwicandelo elibandayo elibunjiweyo elinentsimbi ligobile, ngelixa ukusabalalisa uxinzelelo olushiyekileyo kwi-hot-rolled or welded steel luhlobo lwefilimu.

3. Ukuqina kwe-torsional yamahhala yentsimbi eshushu-eshushu iphezulu kuneyentsimbi epholileyo, ngoko ke ukusebenza kwe-torsional yensimbi eshushu ingcono kuneyentsimbi epholileyo.

Amanqaku aphambili kwimarike yasekhaya: Q195, Q215B, Q235B, kunye nemarike yamazwe ngamazwe:: S235JR, SS400, A36, S275JR, S275J0, SS490,SPHT1,SPHT2,SPHC,SPHD,SPHE. Imveliso isetyenziswa ngokubanzi kumbhobho odityanisiweyo, isakhiwo sensimbi, ishelufu, i-hardware, oomatshini, izithuthi kunye namanye amashishini. Uluhlu lobungakanani: (1.5-25.4) * (940-2000) mm

Iimveliso ezishushu ziqengqeleka zineempawu ezibalaseleyo ezinje ngokuqina okuphezulu, ukuqina okuhle, ukusetyenzwa lula kunye ne-weldability elungileyo, ngoko ke zisetyenziswa ngokubanzi kumashishini okuvelisa anjengeenqanawa, iimoto, iibhulorho, ukwakhiwa, oomatshini kunye noxinzelelo lwemikhumbi.

Izinto ezilungileyo kunye nokungalunganga kokuqengqeleka okushushu:

Izinto eziluncedo: Iyakwazi ukutshabalalisa isakhiwo sokuphosa i-ingot yensimbi, ihlambulule iinkozo zetsimbi, kwaye isuse iziphene ze-microstructure, ukwenzela ukuba isakhiwo sensimbi sinobunzima kwaye iimpawu zomatshini ziphuculwe. Olu phuculo lubonakaliswa ngokuyinhloko kwi-rolling direction, ukwenzela ukuba insimbi ingabi yi-isotropic kwinqanaba elithile; amaqamza, iintanda kunye nokukhululeka okwenziwa ngexesha lokugalela nako kunokudityaniswa phantsi kobushushu obuphezulu kunye noxinzelelo.

ukusilela:

1. Emva kokutshisa okutshisayo, i-non-metallic inclusions (ikakhulukazi i-sulfides kunye ne-oxides, kunye ne-silicates) ngaphakathi kwentsimbi igxininiswe kumaphepha amancinci, kwaye i-delamination (interlayer) iyenzeka. I-Delamination yonakalisa kakhulu iipropathi zentsimbi kwi-tension ngokusebenzisa ubukhulu, kwaye kukho ithuba lokukrazula kwe-interlaminar njengoko i-weld iyancipha. Uxinzelelo lwendawo olubangelwa yi-shrinkage ye-weld luhlala lufikelela amaxesha amaninzi kwi-strain point point point isivuno, esikhulu kakhulu kunobunzima obubangelwa ngumthwalo;

2. Uxinzelelo olushiyekileyo olubangelwa kukupholisa okungalinganiyo. Uxinzelelo olushiyekileyo luxinzelelo lwangaphakathi lokuzilinganisa ngaphandle kwamandla angaphandle. Amacandelo entsimbi eshushu ashushu amacandelo ahlukeneyo anolu hlobo loxinzelelo olushiyekileyo. Ngokuqhelekileyo, ubukhulu becala ubukhulu becandelo lentsimbi yecandelo, lukhulu loxinzelelo olushiyekileyo. Nangona uxinzelelo olushiyekileyo luzilungelelanisa, lusenempembelelo ethile ekusebenzeni kwelungu lensimbi phantsi kwesenzo samandla angaphandle. Ngokomzekelo, ingaba nemiphumo emibi kwi-deformation, ukuzinza, ukuxhathisa ukukhathala, njl.

Izinto ezilungileyo kunye nokungalunganga kokuqengqeleka okubandayo:

Izinto eziluncedo: ukukhawuleza ukwenza isantya, ukukhutshwa okuphezulu, kwaye akukho monakalo kwi-coating, unokwenziwa kwiifom ezahlukeneyo ze-cross-sectional ukuhlangabezana neemfuno zemiqathango yokusetyenziswa; ukuqengqeleka okubandayo kunokubangela ukuguqulwa okukhulu kweplastiki yentsimbi, ngaloo ndlela kuphuculwe isivuno sentsimbi yentsimbi.

ukusilela:

1. Nangona kungabikho ukunyanzeliswa kweplastiki ye-thermal ngexesha lenkqubo yokwenza, kusekho uxinzelelo oluseleyo kwicandelo, eliya kuchaphazela ngokuqinisekileyo iimpawu ze-buckling jikelele kunye neendawo zendawo zensimbi;

2. Isitayela sentsimbi yecandelo elibandayo ngokuqhelekileyo licandelo elivulekileyo, ukwenzela ukuba ukuqina kwe-torsional kwamahhala kwecandelo kuphantsi. Kulula ukuyijija xa igobile, kwaye kulula ukuyibopha xa ixinzelelwe, kwaye ukusebenza kwayo kwe-torsional kubi;

3. Ubunzima bodonga lwentsimbi eyenziwe ngokubanda epholileyo buncinci, kwaye akukho ukuqina kwikona apho amacwecwe adibaniswe khona, kunye nokukwazi ukumelana nemithwalo egxininisiweyo yendawo ibuthathaka.

Ibakala eliphambili lentsimbi libandakanyaSAPH370、SAPH400、SAPH440、QStE340TM、QStE420TM、330CL、380CL、510L、610L）. Ngoku iimveliso zentsimbi yeemoto zibhekisa kwintsimbi yesondo yeMoto, intsimbi yentsimbi yentsimbi, intsimbi yesakhiwo semoto, njl. Izigqubuthelo zokulinganisa (2.5-14) * (1010-2000) mm

Pickling plate (Pickling plate, pickled steel board) yenziwe kumgangatho ophezulu oshushu-rolled sheet njengento ekrwada. Emva kokuba iyunithi yokuchola isuse umaleko we-oxide, inqumle umphetho, kwaye igqibe, umgangatho womphezulu kunye neemfuno zokusetyenziswa (ubukhulu becala obubandayo okanye ukusebenza kwesitampu) Imveliso ephakathi phakathi kweshiti eliqengqelekayo elishushu kunye neshiti eliqengqelekayo liyimveliso efanelekileyo endaweni. ishiti eliqengqelekayo elishushu kunye neshiti eliqengqiwe ngokubanda. Xa kuthelekiswa namaphepha ashushu ashushu, iingenelo zamaphepha atyunjiweyo ikakhulu: 1) Umgangatho ophezulu ulungile. Ekubeni amashidi atyunjiweyo ashushu asusa isikali se-oxide yomhlaba, umgangatho wentsimbi uphuculwe, kwaye ulungele ukuwelda, i-oiling kunye nepeyinti. I-2) Ukuchaneka kwe-dimensional kuphezulu. Emva kokulinganisa, i-plate shape inokutshintshwa kwinqanaba elithile, ngaloo ndlela inciphisa ukuphambuka kokungalingani. 3) Phucula umphezulu wokugqiba kwaye uphucule umphumo wokubonakala. I-4) Inokunciphisa ukungcoliseka kwendalo okubangelwa kukukhethwa komsebenzisi.

Iinkqubo eziphambili zeepleyiti ezikhethiweyo ezishushu zifakwe kwi-laser welding, i-position stretching and straightening, i-turbulent pickling, ukulinganisa kwi-intanethi, ukucheba i-edge, kunye ne-oiling intanethi, njl.

Ukuchongwa kwe-Baosteel ngokubanzi 1.0-6.1 * 800-1650mm. Iimveliso zibandakanya amabakala aphantsi, aphakathi, kunye naphezulu-amandla aphezulu ensimbi yokunyathela, intsimbi yezakhiwo zeemoto, njl., kwaye zihanjiswa ikakhulu ngendlela yeentsimbi zetsimbi. Iimpawu zobuchwepheshe Sebenzisa i-hydrochloric acid ukususa isikali se-iron oxide kwipleyiti yentsimbi eshushu eqengqelekayo ukuze ufumane indawo entle negudileyo.

1. Ukusetyenziswa okuphambili kwe-hot-rolled pickling kwi-automotive industry ngolu hlobo lulandelayo: iinkqubo ze-chassis zemoto, ezibandakanya ii-girders kunye ne-sub-beams. Amavili, kubandakanywa iirim, ii-spokes, njl. Ipleyiti yekhompatimenti ubukhulu becala ngumgangatho wegumbi leelori ezahlukeneyo. Ezinye iindawo zesitampu, eziquka ii-anti-collision bumpers, iibrake housings kunye nezinye iindawo ezincinci ngaphakathi emotweni.

2. Ishishini loomatshini (ngaphandle kweemoto) ikakhulu libandakanya oomatshini belaphu, oomatshini bemigodi, iifeni kunye noomatshini abaqhelekileyo.

3. Izixhobo zombane ezikhanyayo, ezisetyenziswa ikakhulu ukwenza ii-compressor casings, izibiyeli, iitanki zangaphakathi zesifudumezi-manzi, njl.njl. Imiphanda yeekhemikhali.

4. Amanye amacandelo ebhayisekile, imibhobho edityanisiweyo eyahlukeneyo, iikhabhathi zombane, iirayile zohola wendlela, iishelufu zevenkile enkulu, iishelufa zezindlu zokugcina iimpahla, iingcingo, iileli zentsimbi kunye neenxalenye zesitampu seemo ezahlukeneyo.
