Phakathi kwezixhobo zokusika, i-carbide enesamente isetyenziswa kakhulu njengezixhobo zokusika, njengesixhobo sokujika, i-milling cutter, iplaner, i-drill bit, isixhobo esikruqulayo, njl. igraphite, iglasi, ilitye kunye nentsimbi eqhelekileyo, kunye nokusika izinto ezinqandayo ezifana nentsimbi enganyangekiyo ekushiseni, intsimbi engatyiwa, intsimbi ephezulu yemanganese kunye nentsimbi yesixhobo.Ukusika kubonwa ikakhulu ngezixhobo zoomatshini.Okwangoku, inani le-carbide ene-cemented esetyenziselwa ukusika izixhobo ze-akhawunti malunga ne-1 / 3 yemveliso epheleleyo ye-carbide ene-cemented e-China, apho i-78% isetyenziselwa izixhobo ze-welding kunye ne-22% isetyenziselwa izixhobo ze-indexable.
Izixhobo zokusika zisetyenziswa ikakhulu kwimveliso.Izixhobo zokusika i-carbide ezifakwe kwi-cemented zisetyenziswa ngokubanzi kwi-high-speed cutting ngenxa yeempawu zabo ezintle (amandla aphezulu, ukuqina okuphezulu, ubunzima obuphezulu, ukuzinza okuhle kwe-thermal kunye nokuqina kwe-thermal).Amashishini emveli asezantsi afana noomatshini kunye nemoto, inqanawa, uloliwe, ukungunda, impahla, njl.;iindawo eziphezulu kunye nezicelo ezikhulayo zibandakanya i-aerospace, imboni yolwazi, njl.njl. Phakathi kwabo, oomatshini kunye nokuveliswa kweemoto yizona nkalo zesicelo esibaluleke kakhulu sezixhobo ze-carbide ze-cemented kwi-cut cut metal.
Okokuqala, izisombululo ze-mechanical processing ziyimveliso engundoqo ye-cemented carbide industry chain, ejoliswe kwi-downstream yokuvelisa kunye nokucubungula amasimi afana nezixhobo zomshini we-CNC, i-aerospace, i-mechanical mold processing, ukwakhiwa kweenqanawa, izixhobo zobunjineli baselwandle, njl. Ngokutsho kwedatha. yeNational Bureau of statistics, izinga lokukhula konyaka-on-nyaka kushishino China jikelele kunye nezixhobo ezizodwa yokuvelisa iye yaphinda yaphindaphindeka iminyaka emibini elandelelanayo emva bottoming ngaphandle ngo-2015. Ngo-2017, ixabiso lemveliso kushishino lwemveliso jikelele izixhobo yuan 4.7 yetriliyoni , ngokunyuka konyaka nonyaka nge-8.5%;Ixabiso lemveliso yoshishino lwezixhobo ezikhethekileyo liyi-3.66 yetriliyoni yeyuan, ngokunyuka konyaka-nyaka nge-10.20%.Njengoko utyalo-mali lwe-asethi esisigxina kushishino lwemveliso luye lwaphumela ezantsi kwaye lwaphinda lwaphindaphindeka, imfuno yokusetyenzwa kwezisombululo kushishino loomatshini iya kuphinda iphinde iphinde iqhubeke.
Kwimveliso yeemoto, esinye sezona zixhobo zibalulekileyo kwishishini lokwenziwa kweemoto kukubumba isixhobo, kwaye isixhobo se-carbide esinesamente sesona sixhobo sibaluleke kakhulu.Ngokutsho kwedatha ye-Bureau yeSizwe yezibalo, imveliso yemoto ye-China iyonke inyuke ukusuka kwi-9.6154 yezigidi ngo-2008 ukuya kwi-29.942 yezigidi ngo-2017, kunye nezinga lokukhula eliphakathi kwe-12.03%.Nangona izinga lokukhula livame ukuhla kwiminyaka emibini yakutshanje, phantsi kwemvelaphi yesiseko esiphezulu, imfuno yokusetyenziswa kwezixhobo zokusika i-carbide kwintsimi yeemoto iya kuhlala izinzile.
Ngokubanzi, kwintsimi yokusika, isantya sokukhula kweemoto zemveli kunye neshishini loomatshini lizinzile, kwaye imfuno ye-carbide enesamente izinzile.Kuqikelelwa ukuba ngo-2018-2019, ukusetyenziswa kwezixhobo zokusika i-carbide ene-cemented kuya kufikelela kwiitoni ze-12500 kunye neetoni ze-13900 ngokulandelanayo, kunye nezinga lokukhula elingaphezu kwamadijithi amabini.
IJoloji kunye nemigodi: ukubuyiswa kwemfuno
Ngokubhekiselele kwizixhobo ze-geological and mineral, i-carbide ene-cemented isetyenziswa kakhulu njengezixhobo zokugaya amatye, izixhobo zemigodi kunye nezixhobo zokugaya.Iifom zemveliso ziquka ukugrumba amatye okugrumba i-percussive, i-drill bit yokuhlola i-geological, i-DTH Drill yemigodi kunye ne-oilfield, i-cone drill, i-pick of coal cutter kunye ne- impact drill kushishino lwemathiriyeli yokwakha.Izixhobo zemigodi ye-carbide enesamente zidlala indima ebalulekileyo kumalahle, i-petroleum, izimbiwa zetsimbi, ukwakhiwa kweziseko zophuhliso kunye neminye imiba.Ukusetyenziswa kwe-carbide ene-cemented kwi-geological and mining tools kubalelwa kwi-25% - 28% yobunzima be-cemented carbide.
Okwangoku, i-China isephakathi kwinqanaba loshishino, kwaye izinga lokukhula kwemfuno yomthombo wamandla liyancipha, kodwa imfuno epheleleyo iya kuhlala iphezulu.Kuqikelelwa ukuba ngo-2020, ukusetyenziswa kwamandla okuqala eChina kuya kuba malunga neetoni ezi-5 zeebhiliyoni zamalahle asemgangathweni, iitoni ze-750 yezigidi zentsimbi yentsimbi, iitoni ze-13.5 yezigidi zobhedu olusulungekileyo kunye ne-35 yezigidi zeetoni ze-aluminium yokuqala.
Phantsi kwemvelaphi yokusebenza kweemfuno eziphezulu, ukuhla komgangatho wezimbiwa kuqhubela phambili kunyanzela amashishini emigodi ukuba anyuse inkcitho eyinkunzi.Ngokomzekelo, ibakala eliphakathi lentsimbi yegolide lehla ukusuka kwi-10.0 g / T ekuqaleni kweminyaka yee-1970 ukuya malunga ne-1.4 g / T ngo-2017. Oku kufuna ukwandisa imveliso ye-ore eluhlaza ukugcina uzinzo lwemveliso yesinyithi, ngaloo ndlela uqhuba imfuno izixhobo zemigodi ukunyuka.
Kule minyaka mibini izayo, njengoko amaxabiso amalahle, i-oyile kunye nezimbiwa zesinyithi ehlala exhomile, kulindeleke ukuba ukuzimisela kwemigodi kunye nokuhlola kuya kuqhubeka nokunyuka, kwaye imfuno ye-carbide enesamente yezixhobo zejoloji nezemigodi iya kuqhubeka inyuka kakhulu.Kulindeleke ukuba izinga lokukhula kwemfuno liya kugcinwa malunga ne-20% kwi-2018-2019.
Nxiba izixhobo zombane ezixhathisayo: ukukhululwa kwemfuno
Ukunxiba i-carbide enesamente exhathisayo isetyenziswa ikakhulu kwimveliso yesakhiwo soomatshini bemimandla eyahlukeneyo yokunxiba, kubandakanywa nokungunda, uxinzelelo oluphezulu kunye nobushushu obuphezulu, iindawo ezinganyangekiyo, njl. I-8% yesiphumo esipheleleyo se-carbide ene-cemented, kunye ne-cavity yoxinzelelo oluphezulu kunye ne-akhawunti yokumelana nobushushu obuphezulu malunga ne-9% yemveliso epheleleyo ye-carbide ene-cemented.Amalungu angagugiyo abandakanya umbhobho, isiporo sesikhokelo, iplunger, ibhola, iphini lokuchasa isondo lokutyibilika, ipleyiti yescraper yekhephu, njl.
Ukuthatha umngundo njengomzekelo, ngenxa yamashishini asebenzisa ukubumba ngokungqongqo ngakumbi, kubandakanya imoto, izixhobo zasekhaya, yona kunye namanye amashishini abathengi ngokusondeleyo kubomi bemihla ngemihla yabantu, phantsi kwemvelaphi yokuphucula ukusetyenziswa, ukuhlaziywa kweemveliso kukhawuleza kwaye ngokukhawuleza. , kwaye iimfuno zokungunda nazo ziphezulu kwaye ziphezulu.Kuqikelelwa ukuba izinga lokukhula elihlanganisiweyo lemfuno ye-carbide ye-diecemented kwi-2017-2019 iya kuba malunga ne-9%.
Ukongezelela, imfuno ye-carbide ene-cemented ye-high-pressure kunye ne-high-temperature resistant cavities kunye ne-wear-resistant mechanical parts kulindeleke ukuba inyuke nge-14.65% kunye ne-14.79% ngokulandelanayo kwi-2018-2019, kwaye imfuno iya kufikelela kwiitoni ze-11024 kunye neetoni ze-12654. .
