Ukukhiqizwa kwe-welding consumables ezweni lami ngokuvamile kuye kwanda ngokuhambisana nensimbi, futhi umphumela uqhubekile nokwanda eminyakeni yamuva. Ukubala ama-electrodes nezintambo kuphela, umphumela wawungamathani angu-629,600 ngo-1996, amathani ayizigidi ezingu-1.449 ngo-2002, kanye namathani ayizigidi ezingu-1.7 ngo-2003 (okuhlanganisa amathani ayizigidi ezingu-1.2 zama-electrode, amathani angu-300,000 ezintambo eziqinile, ama-subwire angu-35,000 ama-subwire 200,000xXNUMX, I-Welding wire flux engamathani angama-XNUMX), iyizwe elikhulu kunawo wonke emhlabeni elikhiqiza izinto zokushisela kanye nezwe elisetshenziswayo. 

Nokho, okukhipha manual Welding electrode in the consumables Welding ezikhiqizwa ezweni lami bekulokhu kubalwa cishe 75%, futhi isamba isamba izintambo ezihlukahlukene Welding cishe 25%. Uma kubalwa ngesisekelo sensimbi efakiwe, ngo-2002, izinga lokushisela nokushintshashintsha kwemishini ezweni lami lingafinyelela kuphela ku-40.1%, kuyilapho amazwe athuthukile ezimbonini emhlabeni ngokuvamile engaphezulu kuka-60% -70%. Kuyabonakala ukuthi izinga le-automation lokukhiqizwa kwe-welding ezweni lami lisephansi ngokujwayelekile. Igebe phakathi kwemboni yezwe lami yezinto ezisetshenziswayo zokushisela kanye namazwe anezimboni alisekho ngokomkhiqizo, kodwa ngokwezinga lilonke kanye nezinga locwaningo lwesayensi, okuhlanganisa izinga labasebenzi, izinga lokuphatha, okokusebenza kokukhiqiza, ubuchwepheshe bokuhlola, ukuthuthukiswa komkhiqizo nokunye.

1. Induku yokushisela

Njengamanje, kunabakhiqizi abangaba ngu-500 be-welding electrode ezweni lami, abangaba ngu-300 abanezimo eziphelele zokukhiqiza, izindlela zokuhlola kanye nesistimu yokuqinisekisa ikhwalithi enengqondo, futhi cishe i-200 inemibandela ethile yokukhiqiza kodwa ayinazo izindlela zokuhlola. Amandla okukhiqiza embonini angaba amathani ayizigidi eziyi-150. Ngo-2003, umphumela wenduku yokushisela wawungamathani ayizigidi ezingu-1.2.

Abakhiqizi be-electrode abashiselayo batholakala kuzo zonke izifunda ngaphandle kwaseTibet, futhi izinhlobo zabo zomnotho zihlanganisa okuphethwe nguhulumeni, okuhlangene, okuyimfihlo, okuhlanganyelwe, ubunikazi bomhlaba kanye nokuba namasheya. Izinti zokushisela zikhiqizwa kubakhiqizi abaningana abakhulu bezinto ezisetshenziswayo zokushisela, njenge-Tianjin Jinqiao Welding Materials Company, iTianjin Bridge Group Company, iSichuan Atlantic Group Company, njll. Izinhlobo ikakhulukazi ngama-electrode ensimbi esakhiwo, kanye nama-electrodes ensimbi angashi, insimbi engagqwali. ama-electrode, ama-electrode avela phezulu, ama-electrode asekelwe ku-nickel, ama-electrode ensimbi asakazwayo namanye ama-electrode anezinjongo ezikhethekile.

2. Intambo yokushisela

2.1, igesi evikelwe ngocingo oluqinile lokushisela

Njengamanje, kunabakhiqizi bezintambo zokushisela ezivikelwe ngegesi ezingama-200-250 ezweni, futhi cishe amasethi angama-50 emishini yokukhiqiza ehlukahlukene angenisiwe evela eJalimane, eSweden, eCanada, eJapan, eSwitzerland, e-Italy naseTaiwan, nangaphezulu kwe-100 yasekhaya. noma amathuluzi okuzakhela wona. Umthamo wokukhiqiza wonyaka useduze namathani angama-600-700,000. Ngo-2003, ukuphuma kocingo oluqinile lwe-welding kwaba amathani angama-300,000.

Amabhizinisi okukhiqiza izintambo zokushisela eziqinile akhiwe kakhulukazi okukahulumeni, okuhlangene, okuzimele, okuhlanganyelwe kanye ne- sole proprietorship. Ezinye izitshalo ezinkulu zokukhiqiza ama-electrode ama-welding kancane kancane ziye zaba umgogodla wokukhiqiza izintambo zokushisela. Izitshalo ezinkudlwana zokukhiqiza zihlanganisa i-Jinzhou Jintai Metal Industry Co., Ltd., i-Sichuan Atlantic Welding Wire Products Co., Ltd., njll. Nokho, kunezinhlobo ezimbalwa zezintambo zokushisela ezivikelwe igesi. Ngaphandle kwamamodeli e-ER49-1 kanye ne-ER50-6, anomthamo omkhulu wokukhiqiza, iningi lezinye izinhlobo zinomphumela omncane.

2.2. Intambo yokushisela evikelwe ngegesi

Intambo yokushisela ene-flux-cored ethuthukisiwe, ngenxa yokusebenza kwayo okuyingqayizivele, isiphenduke i-welding ekhula ngokushesha kakhulu esetshenziswayo ezweni lami, isuka ngaphansi kwamathani ayi-1,000 (ikakhulukazi ucingo oluwugqinsi) ngo-1996 kuya kumathani angama-35,000 (ikakhulukazi ucingo oluncane) ngo-2003, Ithuthukiswa isilinganiso sokukhula konyaka esingaphezu kwama-50%. Esikhathini esedlule, yayithembele kakhulu ekuthengeni kwamanye amazwe. Manje ngaphezu kwe-50% ye-flux-coreed welding wire esetshenziswa e-China ikhiqizwa ngokwayo, futhi kunenani elincane lokuthunyelwa ngaphandle. Izinkambu zokufaka izicelo ziye zanda kancane kancane kusukela ekwakhiweni kwemikhumbi kuya ekwakhiweni, amabhuloho, imishini esindayo, ama-boilers, imikhumbi yokucindezela, amapayipi, izakhiwo zensimbi nezinye izimboni.

Kunabakhiqizi abangama-29 bezintambo zokushisela ezinamazinyo e-flux-cored ezweni lonke kanye nemigqa yokukhiqiza engama-49, okuhlanganisa imigqa yokukhiqiza engu-25 evela kwamanye amazwe (kuhlanganise nemithathu eyenziwe eTaiwan) kanye ne-3 ekhiqizwa ekhaya, enamandla okukhiqiza ngonyaka angaphezu kwamathani angu-24. Kunezitshalo ezingu-50,000 zokukhiqiza izintambo ezinkulu ezinezintambo ezinkulu e-China, okuyi-Tiantai Welding Materials (Kunshan) Co., Ltd., Guangtai Welding Materials Co., Ltd., Tianjin Sanying Welding Industry Co., Ltd., kanye ne-Antai Technology Co., Ltd. Welding Materials Division Company (Beijing Ganglian Welding Materials Co., Ltd. ihlanganiswe nale nkampani ngo-4).

Njengamanje, imikhiqizo yezwe lami yezintambo zokushisela ene-flux-cored ikakhulukazi ihlanganisa uchungechunge oluthathu lokuvikela igesi ye-titanium, ukuvikelwa kwegesi ye-alkaline kanye nokufakwa phezulu okungagugi. Zifanele i-carbon steel, i-low-alloy high-strength steel, insimbi engagqwali, njll., futhi ingahlangabezana nezidingo zokushisela zezakhiwo zobunjiniyela ezijwayelekile.

2.3. Intambo yokushisela ye-arc engaphansi kanye ne-flux

Ukukhishwa kwezintambo zokushisela ezingaphansi kwamanzi kukhuphuke kakhulu eminyakeni yamuva nje, kodwa kubalela cishe u-5.5% wesamba sezinto ezisetshenziswayo zokushisela. Ingxenye yezintambo zokushisela ezingaphansi kwamanzi emazweni athuthukile ngokwezimboni ngokuvamile iphakathi kuka-8-10%.

Njengoba ukukhiqizwa kocingo lokushisela olungaphansi kwamanzi kulula, zombili izimboni ezijwayelekile zama-electrode kanye nezimboni zocingo lwensimbi zingakunikeza. Kunamakhulu ezinkampani ezingahlinzeka ngezintambo zokushisela ezingaphansi kwamanzi, futhi ezinye izinkampani ziwuhlinzeka ngediski. Umphumela ngo-2003 wawungamathani angaba ngu-80,000.

Kukhona ikakhulukazi izinhlobo ezimbili zama-arc fluxes angaphansi kwamanzi, uhlobo lokuncibilika kanye nohlobo lwe-sintered. Izwe lethu likhiqiza futhi lisebenzisa i-smelted flux. Njengamanje, kunezinkampani ezikhiqiza i-flux ezingaphezu kuka-30 ezinamandla okukhiqiza ngonyaka angaba amathani ayi-150,000, okuncibilika kwawo okungamathani ayi-110,200,000, kanti i-sintered flux ingamathani angama-30,000 kuye kwangama-40,000. Kunezinkampani ezingaphezu kwe-10 ezikwazi ukukhiqiza i-sintered flux. Eminyakeni yamuva, imakethe ye-sintered flux Ngokukhula okuqhubekayo, ingxenye ye-sintered flux in the flux nayo iyanda. Ngo-2003, ukukhishwa kwe-arc flux engaphansi kwamanzi kwakungamathani ayi-120,000.

3. Kunezinkinga

⑴ Intengo yemakethe yasekhaya yezinto ezisetshenziswayo zokushisela iphansi kakhulu, ikakhulukazi intengo ye-welding rod iphansi kakhulu, ibangela umbuthano ononya;

⑵ Kunemikhiqizo embalwa ekhethekile, efana nezinduku zokushisela ezinentuthu ephansi ezisetshenziselwa ukuvala iziza, izinduku zokushisela ezinekhono eliqinile lokulwa nokugqwala ezinamekwe ngesendlalelo esilwa nokugqwala, njll.;

(3) Izinhlobonhlobo zezintambo zokushisela eziqinile zincane, ezinqunyelwe kakhulu ukuhlinzekwa kwensimbi.
