Wararka - Xaaladda hadda jirta ee wax soo saarka carbide tungsten ee Shiinaha

Isticmaalka gudaha Shiinaha ee tungsten wuxuu ahaa mid deggan qiyaas ahaan qiyaastii 10,000 tan / sannadkii.Sida laga soo xigtay warbixinnada, isticmaalka tungsten ee Shiinaha wuxuu ahaa 9,200 tan, 9,400 tan iyo 9,500 tan 1994-1996, isticmaalka tungsten ee Shiinaha ayaa la saadaaliyay inuu noqon doono 11,500 tan sannadkii 2000. Tan iyo 1980-yadii, isticmaalka dhismaha tungsten ee Shiinaha Shiinuhu si deggan ayuu isu beddelay.Tirakoobyadu waxay muujinayaan in laga bilaabo 1980 ilaa 1985, qaab dhismeedka isticmaalka tungsten ee samaynta birta ayaa lagu xisaabiyay 61% wadarta guud ee isticmaalka, xisaabinta saamiga ugu badan;Laga soo bilaabo 1986 ilaa 1990, saamiga tungsten ee loo isticmaalo samaynta birta ayaa hoos u dhacay 48%, halka saamiga tungsten ee loo isticmaalo carbide sibidhka uu kordhay ilaa 28%.Laga soo bilaabo 1991 ilaa 1995, markii wax soo saarka carbide sibidhka kor u kacay, saamiga tungsten ee loo isticmaalo carbide sibidhka ayaa dhaaftay tii tungsten loo isticmaalo samaynta birta, ku dhawaad 50% wadarta isticmaalka tungsten gudaha, halka saamiga tungsten ee loo isticmaalo samaynta birta uu hoos ugu dhacay ilaa qiyaastii. 40%

Waa wax iska cad in isbeddelka qaab dhismeedka isticmaalka tungsten ee Shiinaha uu si toos ah ula xiriiro wax soo saarka carbide sibidhka.Haddaba, waa maxay isbeddelka wax-soo-saarka karbidhidka sibidhka ee Shiinaha?Isbeddelka hadda ee wax soo saarka carbide ee Shiinaha.

Shiinahacarbide sibidhka ahWarshaduhu waxa ay bilowdeen bartamihii 1950-aadkii, inkasta oo nidaamka wershadaha la sameeyay muddo soddon sano ah ka dib marka loo eego wadamadii hore u maray ee Bari iyo Galbeed, haddana xawliga horumarkiisa iyo baaxadda wax-soo-saarkeedu waxa uu ahaa mid cajiib ah oo caalamka ka muuqda.Gaar ahaan sagaashameeyadii, hoos u habeynta iyo furitaanka iyo dhaqaalaha ku jihaysan suuqa, wax soo saarka carbide sibidhka ayaa kor u kacayay.Waqtigan xaadirka ah, waxaa Shiinaha ku sugan 150 warshadood oo carbide sibidh ah, oo leh wadarta wax soo saarka ee 9,000-10,000 tan / sannadkii.Wadarta guud ee wax soo saarka sanadlaha ah waa qiyaastii 7000-7500 tan, oo ka dhigan 21% wadarta wax soo saarka sanadlaha ah ee aduunka, taas oo ka badan Maraykanka, Sweden, CIS iyo wadamada kale ee leh nidaamka warshadaha carbide sibidhka horumarsan ee wax soo saarka hore iyo dunida ugu horeysay. .Muddadii Qorshaha Shanta Sano ee 8aad, celceliska wax-soo-saarka sanadlaha ee karbidhida sibidhka ee Shiinaha wuxuu ahaa 6528 tan (wax soo saarka sannadlaha ugu sarreeya wuxuu ahaa 7540 tan 1994), celceliska isticmaalka sannadlaha wuxuu ahaa 5894 tan (isticmaalka sannadlaha ugu sarreeya wuxuu ahaa 6620 tan) .Sida laga soo xigtay saadaasha khubarada, muddada sagaalaad ee qorshaha shanta sano, celceliska wax soo saarka sanadlaha ah ee carbide sibidhka ee Shiinaha ayaa kordhin doona 6%, tusaale ahaan, celceliska wax soo saarka sanadlaha ah wuxuu gaari doonaa 6976 tan.Khubarada qaarkood waxay adeegsadaan isla'egta toosan si ay ugu xidhaan birta iyo karbidhida sibidhka ee Shiinaha inta lagu jiro Qorshaha Shanta Sano ee Sagaalaad.Jilitaanka xisaabta ayaa la sameeyay si loo xisaabiyo labada tilmaame ee GDP.

Saddex, dib u warshadaynta iyo ka faa'iidaysiga qashinka iyo haraagacarbidesi ay ugu kabto yaraanta kheyraadka dabiiciga ah

Khayraadka dabiiciga ahi waa xaddidan yahay, qaylo-dhaanta luminaysa faa'iidada kheyraadka tungsten ayaa dhegahayaga ka dhawaajisay.Xaaladdan khatarta ah, khubaradu waxay dejiyeen tallaabooyin badan oo ka hortag ah iyo tallaabooyin lagu hagaajinayo.Waxaa ka mid ah, habka dib-u-warshadaynta iyo ka faa'iidaysiga haraaga tungsten carbide ee haraaga qashinka ah wuxuu caddeeyay inuu yahay barnaamij qaan-gaar ah, waxtar leh oo la taaban karo.Waa hab wax ku ool ah oo lagu dhimo kharashka wax soo saarka carbide inta lagu jiro muddada tungsten cayriin dabiiciga ah oo badan, iyo arrin muhiim ah oo lagu hagaajinayo la'aanta kheyraad ee hadda iyo mustaqbalka marka tungsten cayriin dabiiciga ah uu noqdo mid sii yaraanaya.Heerka ka faa'iidaysiga guud ee kheyraadka dib loo warshadeeyay waa mid ka mid ah calaamadaha muhiimka ah ee horumarka tignoolajiyada iyo horumarka dhaqaale ee dalka iyo ganacsiga.Dhab ahaantii, dalalka horumaray ee Bariga iyo Galbeedka waxay hore ugu soo dareen dib-u-warshadaynta iyo ka faa'iidaysiga qashinka haraaga ah ee wax soo saarka caadiga ah.Waqtigan xaadirka ah, dib u warshadayntooda iyo ka faa'iidaysigooda qashinka sibidhka ee haraaga ah ayaa gaadhay 30-40% wadarta waxsoosaarka sanadlaha ah.Isticmaalka sanadlaha ah ee birta tungsten ee Shiinaha waa 10,000 oo tan, haddii ay gaari karto 40% dib u warshadaynta, faa'iidooyinkeeda dhaqaale iyo dib u buuxinta kheyraadka waxay noqon doontaa mid aad u badan.Qaado carbide sibidhka tusaale ahaan, wadarta guud ee wax soo saarka carbide sibidhka ee Shiinaha 1994 wuxuu ahaa 7540 tan, marka loo eego xisaabinta 40% soo kabashada, ma aha oo kaliya inaan ka soo kabsan karno ku dhawaad 3000 tan oo birta tungsten ah, laakiin sidoo kale ku dhawaad 240 tan oo birta cobalt ah. .Marka loo eego xisaabinta isticmaalka 2 tan oo tungsten ah 1 tan oo carbide sibidh ah oo la soo saaro, isticmaalka xoogga tungsten waxaa lagu yarayn karaa ku dhawaad 6000 oo tan.Tani waxay shaki la'aan ka ciyaari doontaa door weyn oo lagu yareynayo kheyraadka.Xaaladda aasaasiga ah ee dib-u-warshadaynta iyo ka faa'iidaysiga karbidhida qashinka ee Shiinaha haddaHadhaaga carbide ee qashinka ah ee aan halkan ku tixraacno waxaa ka mid ah laba qaybood: mid waa alaabta aan u qalmin habka wax soo saarka;Midda kale waa aaladaha kaarbiide-ka ee la isticmaalay (dabacaha, madaxyada birta, caaryada, iwm.).

Marka loo eego tirakoobka aan dhamaystirnayn, wadarta guud ee tiradaharaaga carbideWaxaa laga soo saaraa Shiinaha qiyaastii 3500 oo tan sanadkii.Sida laga soo xigtay soo-saareyaasha carbide ee ajnabiga ah, oo ka mid ah aaladaha carbide-ka ee la isticmaalo, guud ahaan marka la hadlo, 12-25% ee gelinta alxanka qashinka ayaa dib loo warshadayn karaa;65-70% qashinka kaarbiidku wuu dhintaa (feerku wuu dhinta, dhinta cadaadis, dhinta sawir, iwm.) dib ayaa loo warshadayn karaa;95-97% ee mashiinnada qashinka lagu dhejiyo ayaa dib loo warshadayn karaa.

Shiinuhu waxa uu bilaabay in uu dib u warshadeeyo oo uu isticmaalo karbidhida qashinka ah wakhti dambe.Sannadkii 1983, mugga dib-u-warshadaynta waxay ahayd 300 oo tan oo keliya, taasoo ka dhigan 8% wax-soo-saarkii sannadkaas;1985kii, waxa uu kordhay in ka badan 400 oo tan, taas oo ka dhigan 10% wax soo saarkii sanadkaas.iyadoo lagu xisaabtamayo 10% wax soo saarka sanadkaas.Sagaashamaadkii, shaqada dib u warshadaynta waxay lahayd horumar weyn.Hadda waxaa jira in ka badan 150 warshadood oo carbide ah oo dalka ka jira, ma aha oo kaliya ku dhawaad 60 warshadood oo yaryar iyo kuwa dhexdhexaad ah ayaa leh tungsten alaabta ceeriin ah oo asal ahaan ka soo jeeda kheyraadka dib loo warshadeeyay, taas oo ah, oo leh miisaanka Zhuzhou Cemented Carbide Factory iyo Zigong Cemented Carbide Limited Company Liability Company (oo hore u ahaan jirtay warshada sibidhka ee Zigong Cemented Carbide) waxa kale oo ay furtay khadka wax soo saarka ee qashinka dib loo warshadeeyay ee kaarbiide sibidhka ku jira.Waqtigan xaadirka ah, mugga dib-u-warshadaynta qaranku wuxuu ka sarreeyaa 1500 tan, taas oo xisaabisa ilaa 20% ama in ka badan wadarta guud ee wax soo saarka karbidhida sibidhka ee Shiinaha waxayna ku dhowdahay heerka Japan.Tignoolajiyada habka dib-u-warshadaynta qashinka haraaga sibidhka sibidhka ayaa ilaa xad dhammaystiran,?Habka dhalaalidda zinc, habka dhalaalidda korantada iyo habka burburinta farsamada ayaa si sax ah loo bartay.Budada carbide tungsten ee dib loo warshadeeyay (WC) iyo budada cobalt (Co), kuwaas oo tayadoodu aad u fiican tahay, ayaa loo isticmaali karaa soo saarida carbide, dheeman macmal ah, alaabta warshadaha birta ah iyo alaabada kale.Waxa jira dhawr gobol oo shaqada dib u warshadaynta iyo dib u warshadaynta ay aad uga firfircoon tahay, kuwaas oo ay ka mid yihiin: Zhuzhou iyo Changsha ee Hunan;Zigong oo ku taal Sichuan;Qinghe ee gobolka Hebei;Jinan oo ka tirsan Gobolka Shandong;Mudanjiang ee Gobolka Heilongjiang, iwm. Soosaarayaasha karbidhida sibidhka ee meelahan waxay ku guulaysteen dib u warshadaynta iyo isticmaalka qashinka sibidhka ee hadhaaga ah.
