Kwishishini lentsimbi, abahlobo bahlala bedibana nezi ntlobo, kwaye kukho nabahlobo abasoloko bengakwazi ukuxelela umahluko phakathi kwabo:
Ngaba i-picling ihlelwa njengokuqengqeleka okubandayo okanye ukuqengqeleka okushushu?
Ngaba ukumila okubandayo kuchazwa njengokuqengqeleka okubandayo okanye ukuqengqeleka okushushu?
Ngaba ukuqengqeleka nzima kuyafana nokuqengqeleka okubandayo?
Ezi ziimbandezelo ezibetha umphefumlo kwintengiso yentsimbi.Iindidi ezibhidayo zinokukhokelela ngokulula kwimingcipheko yentengiselwano kunye neengxabano kunye namabango.
Xa uhlalutya iindidi, into yokuqala yokucacisa yinkcazo yale mveliso.La magama aqhelekileyo adla ngokubhekisa kwiikhoyili zentsimbi yekhabhoni ephantsi:
Ukukha: ngokuqhelekileyo ibhekisela kwiimveliso apho iikhoyili zetsimbi ezishushu ezifakwe kwi-pickling unit ukususa i-surface oxide scale.
Ukuqengqeleka nzima: ngokuqhelekileyo ibhekisela kwikhoyili yentsimbi eshushu echongwe yaza yacuthwa yintsimbi eqengqelekayo ebandayo, kodwa ayizange ifakwe.
Ukuqengqeleka okubandayo: ngokuqhelekileyo kubhekisa kwimveliso yeekhoyili eziqinileyo eziye zafakwa ngokupheleleyo okanye ezingaphelelanga.
Ukubumba okubandayo: ngokuqhelekileyo kubhekiselele kumcu obhityileyo oshushu oqengqelekayo oveliswe nge-ESP eqhubekayo yokusalwa kunye nenkqubo yokuqengqeleka.
Umahluko kwiinkqubo zemveliso
Ukuqonda ezi mveliso zine, kufuneka uqonde umahluko kwiinkqubo zemveliso.
I-Pickling, i-hard rolling, kunye nemveliso epholileyo yokuqengqeleka ziimveliso kwizigaba ezahlukeneyo kwinkqubo yemveli yemveliso.I-Pickling yimveliso yokuqengqeleka okushushu ukususa isikali, kwaye ukuqengqeleka okuqinileyo yimveliso phambi kokuqengqeleka okubandayo kunye nokufunxa.
Nangona kunjalo, ukubunjwa okubandayo kuyimveliso entsha eveliswa ngumgca wemveliso we-ESP (odibanisa iinkqubo ezimbini zokuphosa okuqhubekayo kunye nokutshisa okutshisa kwiyunithi enye).Le nkqubo ineempawu ezimbini zexabiso eliphantsi kunye nokuqina okushushu okuqengqelekayo.Lukhetho olukhethiweyo phakathi kwezityalo ezininzi zetsimbi zasekhaya.Isikhokelo esiphambili sokuhlaselwa kwiminyaka yamuva.
Ukusebenza okubanzi kunye nokwahlukana kwesicelo
Xa kuthelekiswa neekhoyili ezishushu ezishushu, izinto ezisisiseko ze-pickled steel plate azitshintshanga kwaye zihlala zisetyenziswa kwiimeko apho iikhoyili zetsimbi ezishushu zineemfuno eziphezulu zomgangatho ophezulu.Uphawu oluqhelekileyo yi-SPHC, eyaziwa njenge "pickling C material" kwishishini.
Ixabiso le-coil eqiniweyo ayibizi, kwaye ukubunjwa kunye nomgangatho womphezulu awulungile, ngoko ke idla ngokusetyenziswa kuphela kumashishini athile aneenkcukacha ezinqabileyo kunye neemfuno eziphantsi zokusebenza, njengeembambo zeambrela okanye izitshixo zasefektri.Ibakala eliqhelekileyo yi-CDCM-SPCC, eyaziwa ngokuba yi "cold hard C material" kushishino.
Ukusebenza ngokubanzi kweekhoyili zensimbi ezibandayo zihle kakhulu, kodwa ukungahambi kakuhle kukuba iyona nto ibiza kakhulu (iinkqubo ezininzi, iindleko eziphezulu).Ibakala eliqhelekileyo yiSPCC, eyaziwa njenge "cold rolled C material" kushishino.
Ukwenziwa kokwenziwa kweekhoyili ezenziweyo ezibandayo zingcono kakhulu kuneekhoyili eziqiniweyo, kodwa azilunganga njengaleyo yentsimbi epholileyo eqengqelekayo (ichatshazelwa ikakhulu ngamakhono onyango lobushushu kunye nomsebenzi omkhulu wokucaba uqina emva kokuchola).Inzuzo ebalaseleyo kukuba ixabiso liphantsi kakhulu, ngakumbi kuluhlu lobuninzi be-1.0 ~ 2.0, esetyenziselwa ukutshintsha iimveliso ezipholileyo ezingadingi iimfuno eziphezulu zokwenza (ezifana nokuguqa, ukugoba, njl.).
Ekugqibeleni ezinye iingcebiso:
1. I-China inenani elikhulu lemigca yemveliso ye-ESP kwihlabathi.Ngokusekwe kumgaqo wokuba okukhona isenza, kokukhona ikhula ngokukhawuleza, olu luhlu lweenkqubo lunokuphuhla lube ngumnombo omkhulu oneendleko eziphantsi kwiminyaka embalwa.(Kubandakanya i-semi-endless rolling kunye ne-roll cast iipleyiti ezincinci).Kunokubakho ukhuphiswano olukhulu kwintsimbi yekhabhoni ephantsi kwixesha elizayo, kodwa xa ixabiso lezinto eziluhlaza liphantsi, iimveliso ezenziwe eTshayina ziya kukhuphisana ngakumbi kumazwe ngamazwe.
2. Ii-cold-formed coil zikwayi-high-quality dip galvanized substrates.Iipropathi zoomatshini bokuqala ezihluphekayo zinokuphuculwa kwinkqubo yokufunxa yeyunithi yegalvanizing yediphu eshushu, kunye neemveliso zegalvanized zediphu ezishushu kumzobo onzulu zinokuveliswa.Ukongeza, iindleko zayo zinenzuzo yokuqengqeleka kwi-hard-rolled hot-dip substrates eveliswa yinkqubo yemveli.
3. Igama leemveliso ze-ESP liyabhidisa, kwaye akukho sivumelwano sipheleleyo.
