Esinye sezinqumo ezibucayi kakhulu ekuhleleni umugqa wokukhiqiza iketela ukukhethwa kwezinto ezingavuthiwe. Ukukhetha phakathi kuka-304 no-201 insimbi engagqwali kuthinta ngokuqondile ikhwalithi yokugcina yomkhiqizo, izindleko zokukhiqiza, nesithunzi somkhiqizo.
Ukukhetha impahla engalungile kungaholela ekukhiqizweni okuphansi. Isibonelo, lapho welula amaketela ngomshini wokunyathelisa we-hydraulic, umzimba we-kettle ungase uphuke, ukhulise izinga lokukhubazeka kanye nezindleko zokukhiqiza. Njengenkampani enesipiliyoni seminyaka engu-15 kukho kokubili igedlela eliqediwe kanye nokukhiqizwa kwemishini, i-Davinci izokunikeza umhlahlandlela wokuqhathanisa ochwepheshe kusukela kumbono wokumelana nokugqwala, ubulukhuni, izindleko, nomthelela wawo oqondile ezinqubweni zokukhiqiza.
I. Umehluko Oyisisekelo: Umsuka Ekubunjweni Kwamakhemikhali
I-304 Stainless Steel: Into eyaziwayo "yokudla-yebanga". Ukwakheka kwayo okujwayelekile kungu-18% we-chromium (Cr) no-8% we-nickel (Ni). Okuqukethwe kwe-nickel ephezulu kuyinikeza ukumelana nokugqwala okuhle kakhulu kanye nezakhiwo eziguquguqukayo zokucubungula.
201 Stainless Steel: Enye indlela ethuthukisiwe ukonga izindleko. Ithatha indawo ye-nickel nge-manganese (Mn) kanye ne-nitrogen (N), futhi okuqukethwe kwayo kwe-nickel ngokuvamile kungaphansi kuka-4%. Lokhu kubangela ukumelana nokugqwala okubuthakathaka kodwa amandla aphezulu nobulukhuni.
II. Ukuqhathanisa Kwezinga Lobungcweti

304 Insimbi Engagqwali |
201 Insimbi Engagqwali |
Umthelela Ekukhiqizeni Igedlela |
|
1. Ukumelana Nokugqwala |
Kuhle kakhulu |
Ulungile kuya kwabampofu |
304 yiyona ndlela ekhethwayo yokuphepha kokudla. Imelana nokugqwala uma ichayeke emanzini, etiyeni, ekhofini, njll. 201 ijwayele ukuba nemigodi nokugqwala ezindaweni ezinomswakama noma ezine-chlorine, ikakhulukazi ezingafaneleki iziphuzo ezine-asidi. |
|
2. Ubulukhuni & Amandla |
Ubulukhuni obuphansi, ukuqina okuhle kakhulu, kanye ne-ductility. |
Ubulukhuni obuphezulu namandla (ngenxa yokuqukethwe kwe-manganese ne-nitrogen). |
201 inzima futhi inzima kakhulu ukuyicubungula. Kudinga ithoni enkulu (cishe. 10%-15% ngaphezulu) ukuze kunwetshwe umzimba futhi kubangela ukuguga kwesikhunta esinzima kakhulu. |
|
3. Izindleko Zezinto ezibonakalayo |
Okuphakeme (ngenxa yokuqukethwe kwe-nickel ephezulu). |
Ngaphansi (cishe ama-70-80% wezindleko ze-304). |
I-201 inciphisa kakhulu izindleko zempahla eluhlaza ngeyunithi ngayinye, iyenze ithandeke ezimakethe{1}}ezizwelayo. |
|
4. Ukusebenza Kokudweba Okujulile |
Kuhle kakhulu |
Kuhle |
Lona omunye umehluko obaluleke kakhulu. 304ukusebenza kahle kwe-ductility kuyenza ifaneleke ezinqubweni zokudweba ezijulile eziyinkimbinkimbi, iqinisekisa ukwakheka komzimba okushelelayo kanye nezinga lokukhiqiza eliphezulu{1}} linenani eliphakeme kakhulu lokuqina lomsebenzi, eliba lukhuni futhi lishwabane ngokushesha phakathi nokunwetshwa. Emikhiqizweni-ejulile yomzimba, kungase kudingeke inqubo emaphakathi yokudonsa ukuze kuthambise okokusebenza; kungenjalo, ukuqhekeka kungenzeka. |
|
5. Welding Ukusebenza |
Kuhle kakhulu |
Kuhle |
I-304 ihlinzeka ngokusebenza okuzinzile okuhlanganisiwe okushiselwe ngokulahlekelwa okuncane kokugqwala kanye nama-welds amahle, aqinile. 201 abonisa ukumelana nokugqwala okwehliswe kakhulu ezindaweni ezishiselwe, okudinga ukulawulwa kwenqubo okuqinile. |
III. Umhlahlandlela Wokukhetha Okubalulekile Kolayini Bokukhiqiza Igedlela
Khetha i-304 Stainless Steel: Uma imikhiqizo yakho ithi:-amaketela afakwe ekugcineni aphezulu, amaketela kagesi, amaketela omkhiqizo wezingane, noma imikhiqizo eqondise izimakethe ezifana ne-Europe ne-America enezidingo eziqinile zesitifiketi sokudla (njenge-FDA, LFGB); futhi ubeka phambili isithunzi somkhiqizo kanye{2}}nokuqina kwesikhathi eside, ukukhetha izindlela ezingu-304: izinqubo zokukhiqiza ezizinzile, ukwelula umzimba wegedlela okubushelelezi, isivuno esiphezulu somkhiqizo, kanye nengozi ephansi yemakethe.
Cabanga nge-201 Stainless Steel: Uma imikhiqizo yakho ithi: amaketela omnotho, amaketela esipho sokuphromotha, imikhiqizo eqondise izimakethe{1}}ezizwela kakhulu, noma imikhiqizo enesikhathi esifushane sokuphila esilindelwe.
Ukukhetha i-201 kudinga ukucatshangelwa ngokucophelela: Udinga ukulandisa ngezinselele ezibangelwa ubunzima bayo obuphezulu kanye nezinga eliphezulu lokuqina komsebenzi phakathi nesigaba sokuklama umugqa wokukhiqiza. Lokhu kusho ukuthi ungase udinge ukusebenzisa{2}}umshini wokucindezela we-hydraulic ophezulu we-tonnage ukuze welule umzimba webhodwe.
I-304 insimbi engagqwali iyisinqumo esihlakaniphile kulabo abafuna ikhwalithi, ukuphepha, nokusebenza kahle kokukhiqiza. Inikeza isipiliyoni sokukhiqiza esizinzile futhi esithembekile kanye nemikhiqizo yokugcina.
I-201 insimbi engagqwali iyinketho yamasu{1}}abalulekile kuqala, kodwa ishintsha ezinye izindleko zisuke ezintweni ezisetshenziswayo ziye ezinqubweni zokukhiqiza eziyinselele kanye nezingozi ezingaba khona zemakethe.
Awuqinisekile ukuthi iyiphi impahla engcono kakhulu yomkhiqizo wakho kanye nomugqa wokukhiqiza? Vumela uDavinci akuqondise! Sinikeza:
1. Ukukhetha impahla yamahhala kanye nokubonisana nokuhlaziya izindleko; izixazululo zenqubo yokwelula umzimba weketela kanye nezincomo zokukhetha imishini ngokusekelwe ezintweni ezihlukene (isb, ukuncoma umshini wokucindezela we-hydraulic we-tonnage ofanele wezinto ezingu-201);
2. Izinkomba zecala lempumelelo, nokwabelana ngokuthi sisiza kanjani amaklayenti enze izinqumo ezifanele ngokusekelwe ekumeni kwawo emakethe.
3. Isiqondiso sobuchwepheshe bokukhiqiza: Onjiniyela abangochwepheshe banikeza isiqondiso kuyo yonke inqubo yokukhiqiza, okuhlanganisa amapharamitha wemishini yesinyathelo ngasinye, ukulungisa amaphutha amathuluzi, kanye nezindinganiso zokwahlulela imikhiqizo efanelekayo.
4. Ukugcinwa okujwayelekile kwemishini kanye nesikhunta.
