Imakethe ye-hot rolled coil (HRC) njengamanje ihamba endaweni eyinkimbinkimbi eyakhiwe izinto eziguquguqukayo zokunikezwa nokufunwa, izithonya zemithetho, kanye nokushintsha kwesizini. Njengomkhiqizo oyisisekelo embonini yensimbi, ama-hot rolled coils enza indima ebalulekile ezindaweni zokwakha, ukukhiqiza, kanye nezingqalasizinda. Ukuqonda isimo samanje semakethe kufuna ukuhlaziywa okuningi okuhlanganisa izinto zokunikezwa, izitayela zokukhiqiza, ukushintsha kokufunwa, isimo samasheya, kanye nokubheka kwentengo. Lesi sihloko sihlinzeka ngokuhlola okuphelele kwezici, sihlinzeka ngemininingwane ebalulekile kumabhizinisi nababambiqhaza ababandakanyeka ekuhwebeni nasekukhiqizeni insimbi. Ngaphezu kwalokho, sizothinta ukuthi abahlinzeki abahamba phambili njenge-Profit State International banikela kanjani emakethe ngokunikezwa kwemikhiqizo esezingeni kanye nobudlelwano bamasu.

Uhlangothi lokuhlinzeka lwezimakethe zezikhwama ezishisayo luthonywa kakhulu ukutholakala kwensimbi eshisiwe, okuyinto eyinhloko yokwakhiwa kwesinyithi. Idatha yakamuva ikhombisa amazinga okuhlinzeka kwensimbi eshisiwe aqinile, asekelwe ezingeni elizinzile lokusebenza kwemishini yokushisa elilinganiselwa phakathi kuka-80-85%. Nokho, emashalofini athile, izinga lokwenza inzuzo linciphile kancane ngenxa yokwenyuka kwezindleko zezinto zokwakha kanye nezindleko zamandla, okungase kuthinte izinqumo zokukhiqiza.

Izinga lokusebenza kwezimbazo zomlilo ziye zabona ukushintshashintsha okuncane okuthonywe izinhlelo zokugcinwa nokulawulwa kwemvelo kwesifunda okuhlose ukulawula ukukhishwa. Njengoba sisondela kuJulayi, izimboni eziningi kulindeleke ukuthi zenze ukugcinwa okujwayelekile, okuzokwehlisa okwesikhashana ukusetshenziswa kwezimbazo zomlilo futhi, ngenxa yalokho, ukukhiqizwa kwe-hot rolled coil. Lokhu kunciphiswa kokukhiqiza kuzosiza ukuzolisa ukuhlinzekwa kodwa kungase kuqinise ukutholakala okwesikhashana.

Sekukonke, isimo sokuhlinzekwa sibikezela ukwanda okulinganiselayo ekukhiqizweni kwe-hot rolled coil uma kuqhathaniswa nezinye izinyanga, kodwa lokhu kuncishiswe imisebenzi yokugcinwa kanye nemikhawulo yemvelo, ebekela umkhawulo isivinini sokukhuphuka kokukhiqizwa. Lezi zimo zokuhlinzekwa zibalulekile kubahlanganyeli bemakethe ukuthi babikezele izinguquko ezingenzeka ekutholakeni nasezintengweni.

Ngokwesidingo, ukusetshenziswa kwensimbi eshisiwe (hot rolled coil) ibonise izindlela ezixubile muva nje. Umkhakha wezindlu, ovame ukudala isidingo esikhulu sensimbi ekwakheni, ubhekane nokwehla ngenxa yemibandela eqinile yezezimali kanye nomoya wokutshala izimali oqaphe. Lokhu kuholele ekubeni kube nokwehla kwesidingo se-HRC ezintweni zokwakha kanye nezinye izinto ezihlobene.

Ngokuphambene, amaphrojekthi ezisekelo ahlinzeke ngokulinganiselayo kuleli yehlo. Izinyathelo eziholwa uhulumeni ezisebenzisa amanethiwekhi ezokuthutha, izinsiza, nemisebenzi yomphakathi ziye zagcina isidingo esiqinile se-hot rolled coil, yize isivinini singaqinile ngokwanele ukuthi singakhokhelwa ngokuphelele ubuthakathaka esigabeni sezindlu. Izici zesizini nazo zidlala indima, lapho isidingo sivame ukwehla ezinyangeni ezimaphakathi nehlobo.

Sibheke phambili, ukubuka kwesidingo kwekota elandelayo kubonisa ithemba eliqaphile. Ngenkathi isidingo sezindlu singase sihlale siphansi, ukuchitha imali ezisekelweni kulindeleke ukuthi kugcine umfutho wayo. Kuhlangene nezilungiso zesizini, amabhizinisi kufanele alungiselele amazinga esidingo azinzile kodwa angaphansi kancane esikhathini esizayo esiseduze, okuthinta izindlela zokugcina izimpahla kanye nezokubeka amanani.

Izibalo zokukhiqiza i-hot rolled coil zikhombise ukwanda ezinyangeni zamuva nje. Idatha evela emibikweni yezimboni ibonisa ukwanda kwesikhathi nenyanga ekukhiqizeni, nokwanda okubonakalayo ngoJuni uma kuqhathaniswa noMeyi. Lokhu kwanda kubonisa imizamo yezimboni zensimbi yokugcwalisa izinto ezithengiwe ngaphambi kokulindela isidingo sesizini nokubuyisela ukwehla kokukhiqiza okubangelwe imisebenzi yokugcinwa entwasahlobo.

Ukuqhathanisa kwenyanga nenyanga kukhombisa ukuthi nakuba ukukhiqiza kukhula, kusengaphansi kwamandla aphezulu ngenxa yokulungiswa kwamasu abakhiqizi abahlose ukulinganisa ukuhlinzekwa nezimo zangempela zokufunwa. Izimboni zensimbi zisebenzisa ukuguquguquka kwazo ekukhiqizeni ukugwema ukukhiqiza kakhulu, okungadala ingcindezi ehla ezintengweni ze-hot rolled.

Lezi zimo zokukhiqiza zigcizelela imakethe elungisa ngokucophelela, ibonisa ukuqwashisa phakathi kwabakhiqizi ukuthi balingane nokukhiqiza nokusetshenziswa kwemakethe ukuze kugcinwe ukuzinza kwentengo nokwenza inzuzo.

Izinga lamanje lokugcina leziqeshana ezishisayo liye laqoqwa kancane kancane. Lokhu kungenxa yokukhula kwezinga lokukhiqiza ezinyangeni ezedlule kanye nokupholisa kwesizini kokufuna. Imibiko yezitolo zezimboni ibonisa ukuthi ukuhlanganiswa kwezimpahla kuyenzeka ezikhungweni ezinkulu zokuhambisa, kudala isikhala esingathinta amanani emakethe esikhathini esizayo.

Izimpahla ezikhulayo ziveza bobabili ubunzima namathuba. Ngakolunye uhlangothi, izinga elikhulayo lezimpahla lingathinta amanani uma ukufunwa kungakhuphuki njengoba kulindelwe. Ngakolunye uhlangothi, ukuba nezimpahla ezitholakalayo kalula kunganciphisa isikhathi sokulinda kumakhasimende, kuthuthukisa ukuzinza kokuhlinzeka. Le mlinganiselo ibalulekile ukuze ababambiqhaza emakethe bayilandele ngokucophelela.

Ngaphezu kwalokho, isimo sokuphathwa kwezimpahla sikhuliswa yizimpawu zokufuna ezihlanganisiwe ezivela emkhakheni wezindlu nezokwakha, okudala ukungaqiniseki ezinqubweni zokusetshenziswa. Ukuphatha izimpahla kahle kuzoba yisihluthulelo kubahlinzeki nabasabalalisi ukuze bagweme izindleko eziphezulu zokugcina kanye nokwehla kwamanani.

Umoya wemakethe osizungezile insimbi eshisiwe (hot rolled coil) njengamanje uqaphe kodwa uzinzile. Ukuqaliswa kwakamuva kwemikhawulo eqinile yokukhiqiza kwezinye izifunda ezibalulekile ezikhiqiza insimbi kuholele ekubeni kube nokushoda kwesikhashana, okusekela amazinga entengo yesikhathi esifushane. Kodwa-ke, lezi zinyathelo zokulawula ziphinde zibange ukungaqiniseki maqondana nokwethembeka kokuhlinzekwa esikhathini esizayo.

Amathrendi amanani esikhathini esifushane abonisa ingcindezi encane yokukhuphuka njengoba izimboni nabathengisi besabela ezilawulweni eziqinile kanye nokulungiswa kwezinto ezigciniwe. Noma kunjalo, ukubuka konke kwamathrendi amanani esikhathi eside kuhlala kuncike ekulinganiseni ukukhula kokuhlinzekwa nokululama kwesidingo. Uma isidingo esivela emikhakheni emikhulu edlayo siba namandla, amanani angabona ukwanda okuzinzile.

Ukuqubuka kwamandla amanani kuhlala kuyinto ekhathazayo, ikakhulukazi uma izinto zangaphandle ezifana nokuguquguquka kwezindleko zezinto zokusetshenziswa, ukungezwani kwezepolitiki, noma izinguquko zenqubomgomo kuthinta ukukhiqizwa kwensimbi kanye nokuhamba kwezohwebo. Ababambiqhaza emakethe bayelulekwa ukuthi bahlale benolwazi futhi benze kalula ukuze babhekane nalezi zimo ngempumelelo.

Ngokufingqiwe, imakethe ye-hot rolled coil njengamanje ibonakala ngokulingana okubucayi phakathi kokwanda kokuhlinzekwa kanye nesidingo esibuthakathaka. Ukuhlinzekwa kukhula kancane, nakuba kukhona imikhawulo evela ekugcinweni kanye nemithetho yezemvelo. Isidingo sibonisa isithombe esixubile, lapho ingqalasizinda isekela ukukhula okuthile naphezu kwezinselelo emkhakheni wezindlu. Ukwanda kokukhiqizwa kusekela ukugcwaliswa kwesitoko, kodwa ukwanda kwezitoko kungase kubeke ingcindezi emintengweni uma isidingo singathuthuki.

Ababambiqhaza emakethe, okubalwa kubo abathengi nabahlinzeki, kufanele babheke lezi zimo ngokucophelela ukuze bathuthukise amasu okuthenga nokudayisa. Izinkampani ezifana neProfit State International, ezinezinhlobonhlobo zemikhiqizo ezibanzi kanye nobudlelwano obuqinile bemboni, zinikeza izinsiza ezibalulekile zokuzulazula kule makethe eyinkimbinkimbi. Ngeminye imininingwane ngemikhiqizo yensimbi esezingeni eliphezulu kanye nezinsizakalo zabo, vakashela ikhasi le-IMIKHIQIZO. Ngaphezu kwalokho, hlola i-MAYELANA NATHI isigaba singanikeza imininingwane ngobuchwepheshe babo bemakethe kanye nezinzuzo zabo zokuncintisana.
