(1) ipleyiti yentsimbi eqengqelekayo ebandayo ngenxa yokuqina komsebenzi othile, ubulukhuni buphantsi, kodwa inokufikelela kumlinganiselo ongcono wamandla e-flexural, osetyenziselwa iphepha lentwasahlobo eligobayo elibandayo kunye nezinye iindawo.
(2) ipleyiti ebandayo esebenzisa umphezulu ogoqekileyo obandayo ngaphandle kwesikhumba esingcolisiweyo, umgangatho olungileyo. Ipleyiti yentsimbi egoqekileyo eshushu esebenzisa umphezulu ogoqekileyo oshushu, ubukhulu bepleyiti buphantsi komahluko.
(3) Ukuqina kwepleyiti yentsimbi eqengqelekayo eshushu kunye nokuqina komphezulu kuphantsi, ixabiso liphantsi, ngelixa ipleyiti eqengqelekayo ebandayo isolula kakuhle, iqinile, kodwa ibiza kakhulu.
(4) ukuqengqeleka kwahlulwe kwipleyiti yentsimbi eqengqelekayo ebandayo kunye nentsimbi eqengqelekayo eshushu, apho ubushushu bokuphinda kusetyenziswe njengeyona ndawo yokwahlulahlula.
(5) Ukuqengqeleka okubandayo: ukuqengqeleka okubandayo kusetyenziswa ngokubanzi ekuveliseni umcu, isantya sawo sokuqengqeleka siphezulu. Ipleyiti yentsimbi eqengqelekayo eshushu: ubushushu bokuqengqeleka okushushu bufana nobokubumba.
(6) Umphezulu wepleyiti yentsimbi egoqwe ngobushushu ngaphandle kokugqunywa uba mdaka omnyama, umphezulu wepleyiti yentsimbi egoqwe ngobushushu ngaphandle kokugqunywa uba ngwevu, kwaye emva kokugqunywa, unokwahlulwa kubuthambile bomphezulu, obuphezulu kunobo bepleyiti yentsimbi egoqwe ngobushushu.
Inkcazo yomcu wentsimbi osongiweyo oshushu
Ububanzi bomcu oqengqelekayo oshushu obungaphantsi okanye obulingana ne-600mm, ubukhulu bepleyiti yentsimbi eyi-0.35-200mm kunye nobukhulu bomcu wentsimbi oyi-1.2-25mm.
Indawo yeHot Rolled Strip Market kunye neDirection yoPhuhliso
Intsimbi eqengqelekayo eshushu yenye yezona ntlobo ziphambili zeemveliso zentsimbi, esetyenziswa kakhulu kushishino, kwezolimo, kwezothutho nakwezokwakha, kwaye ngaxeshanye ne-cold rolled,umbhobho odibeneyo, intsimbi eyenziwe ngokubandayo kunye nezinye izinto ezikrwada zokuvelisa imveliso yayo kwimveliso yonyaka yentsimbi yaseTshayina kwisixa siphela senxalenye enkulu yendima ephambili ekuveliseni intsimbi eqengqiweyo.
Kumazwe aphuhlileyo kwezoshishino,ipleyiti egoqwe ngobushushukwaye intsimbi ye-strip yayimalunga ne-80% yemveliso iyonke yepleyiti kunye nentsimbi ye-strip, ingaphezulu kwe-50% yemveliso iyonke yentsimbi, kwaye kukhuphiswano lwemarike yamazwe ngamazwe ikwindawo ephambili.
ETshayina, iimveliso zentsimbi ezijikeleziweyo ezishushu ngokubanzi, umda ophantsi wobukhulu yi-1.8mm, kodwa eneneni, bambalwa kakhulu abavelisi okwangoku abavelisa intsimbi ejikeleziweyo eshushu enobukhulu obungaphantsi kwe-2.0mm, nokuba umcu omxinwa, ubukhulu bemveliso ngokubanzi bungaphezulu kwe-2.5mm.
Ngoko ke, inxalenye enkulu yethemba lokuba ubukhulu be-strip engaphantsi kwe-2mm njengabasebenzisi bezinto eziluhlaza, kufuneka basebenzise i-strip egoqwe ngokubandayo.
Umtya oSongiweyo obandayo
Umcu wentsimbi oqengqelekayo obandayo: isinyithi kwiqondo lobushushu lokuphindaphindeka ngaphantsi kokuguqulwa kwe-rolling sibizwa ngokuba yi-cold rolled, ngokubanzi sibhekisela kwi-strip engafudunyezwanga kwaye kwinkqubo yokuqengqeleka ngqo kubushushu begumbi. Umcu ogoqwe ngombala obandayo usenokuba shushu xa uwuchukumisa, kodwa usabizwa ngokuba yi-cold rolled.
Imveliso eqengqelekayo ebandayo inokubonelela ngenani elikhulu lokusebenza okuchanekileyo okuphezulu kunye nokusebenza okugqwesileyo kwepleyiti yentsimbi kunye nestrip, uphawu lwayo olubaluleke kakhulu bubushushu obuphantsi bokucubungula, xa kuthelekiswa nemveliso eqengqelekayo eshushu, inezibonelelo ezilandelayo:
(1) Iimveliso zemicu eqengqelekayo ebandayo zichanekile ngobukhulu kwaye ziyafana ngobukhulu, kwaye umahluko kubukhulu bemicu ngokubanzi awudluli kwi-0.01-0.03mm okanye ngaphantsi, nto leyo enokuhlangabezana ngokupheleleyo neemfuno zokunyamezelana okuchanekileyo.
(2) Imicu emincinci kakhulu engenakuveliswa ngokuqengqeleka okushushu ingafumaneka (eyona incinci ingafikelela kwi-0.001mm okanye ngaphantsi).
(3) Umgangatho womphezulu weemveliso ezigoqiweyo ezibandayo ungcono kakhulu, akukho strip egoqiweyo eshushu edla ngokubonakala inemingxuma, icinezelwe kwi-iron oxide nakwezinye iziphene, kwaye inokuveliswa ngokweemfuno zomsebenzisi zobunzima obahlukeneyo bomphezulu westrip (umphezulu ocwebezelayo okanye umphezulu onemingxuma, njl.njl.), ukuze kube lula ukucutshungulwa kwenkqubo elandelayo.
(4) Intsimbi eqhotsiweyo ebandayo ineempawu ezintle kakhulu zoomatshini kunye neempawu zenkqubo (ezifana namandla aphezulu, umda wesivuno esiphantsi, ukusebenza kakuhle kokuzoba okunzulu, njl.njl.).
(5) Ukuqengqeleka ngesantya esiphezulu kunye nokuqengqeleka okuqhubekekayo ngokupheleleyo kunokufezekiswa, ngemveliso ephezulu.
Ukuhlelwa kwentsimbi yestrip eqengqelekayo ebandayo
Intsimbi eqhotsiweyo ebandayo yahlulwe yaba ziintlobo ezimbini: emnyama nekhanyayo.
(1)umtya omnyama ofakwe i-anneal: umcu oqengqelekayo obandayo ufudunyezwa ngqo ukuya kubushushu bokutsalela, umbala womphezulu ngenxa yokuvezwa kobushushu obuphezulu kumnyama womoya. Iipropati zomzimba ziyathamba, zihlala zisetyenziselwa umcu wentsimbi kunye noxinzelelo olongezelelweyo, ukunyathela, kunye nokuguqulwa kwendlela enkulu yokucubungula enzulu.
(2) umcu oqaqambileyo oqhotsiweyo: kunye ne-black annealed umahluko omkhulu kukuba ukufudumeza akudibani nomoya, kunye ne-nitrogen kunye nezinye iigesi ezingasebenziyo zikhuselwe, umbala womphezulu wokugcina kunye nomcu oqengqelekayo obandayo, ukongeza kwi-black annealed ukusetyenziswa kukwasetyenziselwa umphezulu womphezulu we-nickel plating kunye nezinye iindlela zonyango zomphezulu, ezintle kwaye zinobubele.
Umahluko phakathi kwentsimbi eqaqambileyo kunye nentsimbi emnyama ephelayo: iipropati zoomatshini ziphantse zifane, intsimbi eqaqambileyo ikwintsimbi emnyama ephelayo ngokusekelwe kumanyathelo angaphezu kwesinye onyango olukhanyayo.
Ukusetyenziswa: intsimbi yestrip emnyama enyamalalayo idla ngokwenziwa ibe ziimveliso zokugqibela ngaphambi kokuba yenziwe ukuze kwenziwe unyango lokuhombisa umhlaba, intsimbi yestrip eqaqambileyo inokunyatheliswa ngqo kwiimveliso zokugqibela.
Isishwankathelo sophuhliso lwemveliso yentsimbi eqhotsiweyo ebandayo
Itekhnoloji yokuvelisa imicu eqhotsiweyo ebandayo luphawu olubalulekileyo lophuhliso lweshishini lesinyithi.Ipleyiti yesinyithi ebhityileyo yeemoto, oomatshini bezolimo, ishishini leekhemikhali, ukutya okufakwe kwiinkonkxa, ulwakhiwo, izixhobo zombane kunye nezinye izinto ezisetyenziswa kwimizi-mveliso, kodwa ikwanolwalamano oluthe ngqo nobomi bemihla ngemihla,ezifana neefriji zasekhaya, oomatshini bokuhlamba impahla, oomabonakude kunye nezinye iimfuno zepleyiti yentsimbi ebhityileyo. Ngoko ke, kwamanye amazwe aphuhlileyo kwezoshishino, ipleyiti yentsimbi ebhityileyo yayibalelwa kumlinganiselo wokwanda kwentsimbi minyaka le, kwipleyiti ebhityileyo, intsimbi enomcu, iimveliso eziqengqelekayo ezibandayo zenza inxalenye enkulu.
