I-Hot Rolling Operation Department ye-Rungang Co., Ltd. iphumeze ukuthunyelwa "kweeseshoni ezimbini" kumanqanaba amabini eqela kunye nenkampani, kwaye yaphuma yonke into ukukhuthaza ukusebenza okuphantsi kakhulu, ukusetyenziswa ngokucokisekileyo kunye neendleko, kwaye yaphonononga indawo yokunciphisa iindleko, kwaye yaphonononga i-"3+2" indlela yokuvelisa iziko lokufudumeza., oko kukuthi, umgca wesibini we-double-furnace production of hot rolling, kunye ne "3 + 3" imowudi ibuyiselwe kwizigaba, ijolise ekusebenzeni kakuhle kunye nokusukela ixabiso eliphantsi kakhulu.Xa kuthelekiswa ne "3 + 3" indlela yokuvelisa, ukusetyenziswa kwamafutha kuncitshiswe malunga ne-4.1%, iindleko zemihla ngemihla zokukhutshwa kwegesi yendalo zincitshiswa nge-128,000 yuan, ixabiso lemihla ngemihla lombane othengwayo limalunga ne-85,500 yuan, kunye nokunciphisa iindleko. malunga ne-213,500 yuan ngosuku.
Ukunciphisa iindleko ngaphandle kokunciphisa ukusebenza kakuhle, kunye nokubeka isiseko esiqinileyo sophando lwe-bottleneck.Ngaphantsi kolwalathiso lwekomiti yeqela lesebe lokusebenza, igumbi lobugcisa bokuvelisa liye lakhokela ekulungiseni ingxaki "yentamo" yenkqubo yesithando sokufudumala, kunye nentsebenziswano kunye nesebe lokuvelisa kunye neziko lobuchwephesha ukwenza uphando lweprojekthi.Ngokuqulunqa ubudlelwane obuhambelanayo phakathi kwexesha lokudluliselwa kwe-slab kunye nobushushu bokungena kwisithando somlilo, imigaqo yokuxuba ishushu kunye nebandayo icaciswa, kwaye kwangaxeshanye, imigaqo yokuxuba ubushushu obuphezulu kunye nesezantsi iqulunqwe ukukhuthaza ukucwangciswa kwebhetshi, kwaye khuthaza umgca wemveliso we-2160 ukunciphisa umlinganiselo wokuxuba okushushu kunye okubandayo nge-33%.%.Ngokwenza umsebenzi ofana nokudibanisa kunye nokwandisa ubushushu bokucofa kunye nokwandisa ubukhulu bezinto eziphathekayo zomda we-IF steel kunye ne-BH steel, isiseko esiluqilima sibekwe ukuqhubela phambili ukunyuswa kobuchwephesha bokuqengqeleka kobushushu obuphantsi.inqanaba.Ngokusebenzisa amanyathelo asebenzayo afana nokuhlelwa kwamanqanaba ahlukeneyo entsimbi kunye nemilinganiselo yokumisela ubushushu beziko, kunye nokuphuhlisa umsebenzi wokudibanisa ubushushu phakathi kwamacandelo okufudumeza, ukulungiswa kwemodeli yokutshisa intsimbi ezenzekelayo kuye kwafezekiswa, kunye nomlinganiselo we-2160 yentsimbi ezenzekelayo. ukutsha kunyuke ngama-51% unyaka nonyaka.Ngokuphumelela okulandelelanayo kwenani leengxaki ze "intamo yentamo", ukusebenza kakuhle kokufudumeza kuye kwaphuculwa kakhulu, ukubeka isiseko esilungileyo sokuphonononga indlela entsha yokuvelisa "3 + 2".
Ukuncitshiswa kweziko akunciphisi imveliso, kwaye kwenziwa iinzame zokuphucula ukusebenza kakuhle komgca wokuvelisa.Isebe elisebenza ngokushushu licinezela, laze lalungelelanisa ukusasazwa kombutho wokuvelisa “3+2” weziko lokufudumeza amabini.Ukuqinisa ulungelelwaniso lwenkqubo, ukwakha unxibelelwano lwexesha langempela kunye nesebe lentsimbi yokusebenza kunye nesebe lokuvelisa, qwalasela ngokubanzi izinto ezininzi ezifana nebhalansi ye-billet, ulwakhiwo oluhlukeneyo, ukuzaliseka kwe-odolo, ukunikezelwa kwempahla ekrwada kwinkqubo elandelayo, kunye nomsebenzi wenkunzi ekupheleni. yenyanga, ukucwangciswa kwemveliso yenzululwazi, uxhulumaniso olungenamthungo, kunye nokukhuthazwa okubanzi Imowudi yombutho wemveliso yemigca emibini enye kunye neziko ezimbini ikhuthaza ukusetyenziswa kwamafutha kunye nokunciphisa ukukhutshwa kwekhabhoni.Imigca emibini eshushu eshushu ihlela ngokubanzi amanqaku aphambili okuqengqeleka okuphezulu, ukusebenzisa amandla ngokuchanekileyo, kunye nokuphucula ngokuqhubekayo, ukuze kuqinisekiswe ukuba imveliso ayinciphi kwaye ukusebenza kakuhle akunciphi.
Umgca wemveliso we-1580 uqinisa ngokuqhubekayo umbutho wokucwangcisa imveliso, ngokuqhubekayo uphucula iteknoloji yenkqubo, kwaye uzama ukuphucula ukusebenza kakuhle kwemveliso yesithando somlilo esiphindwe kabini.Idityaniswe neempawu zeemveliso eziqengqelekayo zomgca wemveliso kunye nesicwangciso sezinto kwinkqubo elandelayo, iimveliso ezimbini eziphambili ze-pickling plate kunye ne-silicon yensimbi zihlelwa kwaye zicwangciselwe ukuveliswa kwemveliso ephakathi, kunye neenzuzo zezinga eliphezulu lokutshaja okushushu, ukuchazwa okuphakathi. kunye neebhetshi ezinkulu ze-silicon zentsimbi zisetyenziswa ngokupheleleyo ukuphuhlisa indlela yokuvelisa iziko elimbini..Umgca wemveliso uthatha iprojekthi yolawulo lwe-thermal-process ye-joint-stock company njengendawo yokuqala, ihlunga kwaye iphucule imithetho yokusetyenziswa kwezixhobo zokugquma i-slab, kwaye iqulunqa "Iimfuno zoLawulo lokuPhakanyiswa kweeMibhobho eziKhethekileyo zeeBhodi eziPickled", kwaye iphucula ngakumbi ishedyuli yemveliso "eshiywe ngasemva kwezithuba" kwiibhodi ezifakwe emanzini.Imimiselo, ukomeleza ulawulo lwemingxuma yokufakelwa kwe-thermal, nikela ingqalelo kwishedyuli ye-steelmaking kunye nesimo se-thermal insulation pits, ukuphucula ngokubanzi izinga lokuhambisa ubushushu bokutshaja okushushu, kunye nokunciphisa ukusetyenziswa kwamafutha.Ukuqhuba ngokusebenzayo udidi lokuqala lokulinganisa kunye nomgca wokuvelisa umgca wokulinganisa umsebenzi, ngokuphucula ngokuqhubekayo ulandelelwano lokuguqulwa koluhlu kunye nokulungiswa kwamanyathelo olawulo, ixesha lokutshintsha umqulu ngo-Epreli lincitshiswe ngemizuzwana eyi-15 ukusuka kwinyanga edlulileyo.Ixesha elikhawulezayo lokutshintsha umqulu waqhekeza i-8 ibe yi-7, kunye nexesha eliqhelekileyo lokutshintsha umqulu waqhubela phambili ukuya kwimizuzu eyi-9.Umgca wemveliso ugcina umkhwa omhle wokusebenza kakuhle kunye nokusetyenziswa okuphantsi.
Isithando somlilo asiyi kuyeka ukusebenza, kwaye inkonzo yomlilo iya kulungiswa ngexesha elifanelekileyo.Ukusukela ngo-Epreli 16, umgca wemveliso we-1580 uqalise imveliso yesithando somlilo esiphindwe kabini.Xa ubhubhani omtsha wenyumoniya wabetha, indawo yomzi-mveliso yavalwa yaza yalawulwa.Uninzi lwabasebenzi kunye nabasebenzi bahlala ekhaya kwaye benyamekela wonke umntu.“Ubhubhani” akazange athandabuze ukuhlala kumzi-mveliso ukuqinisekisa imveliso, ngokuqhutywa ngamandla Iinzame zokuphumeza izigqibo zekomiti yeqela.Ngeli xesha, isebe lokusebenza lisebenzise ngokupheleleyo ithuba lokuvalwa ukwenza amalungiselelo okuhlolwa konyaka kunye nenkonzo yeziko.Kwiintsuku ezingama-23, iziko eziko ezintathu zokufudumeza zagqitywa ngempumelelo, iitoni ezingama-408 zeslag zacocwa, iitoni ezili-116 zezinto ezikwaziyo ukuxhathisa zatshintshwa zaza zalungiswa, iivalve ezili-110 zatshintshwa zaza zalungiswa, kwakhutshwa imibhobho engama-78, kwaza kwakhutshwa imibhobho yokuphakama. kulinganiswe izihlandlo ezingaphezu kwe-1,400.Iyonke imisebenzi yokugcinwa kwe-82 iye yagqitywa, kwaye iziko ezintathu zokufudumeza ziqalisiwe kwaye zamiswa amaxesha angama-7.Lo msebenzi wesithando somlilo wabelana ngoxinzelelo lwechungechunge lokulungiswa konyaka, kwaye uqokelele amandla aneleyo kwimveliso elandelayo ephezulu kunye nosetyenziso oluphantsi.
Kwinqanaba elilandelayo, isebe le-hot rolling operation liya kuqhubeka ligxininisa kwimveliso ephezulu kunye nokusetyenziswa okuphantsi, ukuqhubeka nokucofa amandla okunciphisa iindleko, kunye nokuqhuba ngokupheleleyo umsebenzi ophantsi kakhulu.
