I-carbide ene-cemented yimathiriyeli yealloyi eyenziwe ngekhompawundi eqinileyo yentsimbi ephikisayo kunye nentsimbi edityanisiweyo ngenkqubo yesinyithi somgubo.Uneempawu zobunzima obuphezulu, ukuxhathisa ukugqoka, amandla kunye nokuqina.Ngenxa yeempawu zayo ezikhethekileyo, isoloko isetyenziselwa ukwenza izixhobo zokugaya amatye, izixhobo zemigodi, izixhobo zokugaya, izixhobo zokulinganisa kunye nokunye.Isetyenziswa kakhulu kwi-petroleum kunye negesi yendalo, ishishini lemichiza, oomatshini bokwakha, ulawulo lolwelo kunye nezinye iindawo.I-carbide enesamente yimathiriyeli ecinezelwe ngumgubo wesinyithi.Namhlanje, uChuangrui Xiaobian uya kukwazisa iingxaki ezininzi ezinkulu esihlala sidibana nazo kwinkqubo yokucinezela, kwaye sihlalutye ngokufutshane izizathu.
1. Eyona nkunkuma ixhaphakileyo yokucinezela inkunkuma kwi-cemented carbide pressing process yi-delamination
Ukubonakala ecaleni komphetho webhloko yoxinzelelo, kwi-engile ethile ukuya kumphezulu woxinzelelo, ukwenza ujongano olucocekileyo lubizwa ngokuba yi-delamination.Uninzi lwamaleko luqala kwiikona kwaye ludlulele kwi-compact.Isizathu se-delamination ye-compact yi-elastic yangaphakathi yoxinzelelo okanye i-elastic tension kwi-compact.Ngokomzekelo, umxholo we-cobalt womxube uphantsi, ubunzima be-carbide buphezulu, i-powder okanye i-particle incinci, i-arhente yokubumba incinci kakhulu okanye i-distribution ayifani, umxube umanzi kakhulu okanye womile kakhulu, uxinzelelo olucinezelayo lukhulu kakhulu, ubunzima beyunithi bukhulu kakhulu, kwaye amandla oxinzelelo aphezulu kakhulu.Ubume bebhloko buntsokothile, ukugqitywa kokungunda kubi kakhulu, kwaye umphezulu wetafile awulingani, nto leyo enokubangela i-delamination.
Ke ngoko, ukuphucula amandla e-compact kunye nokunciphisa uxinzelelo lwangaphakathi kunye ne-elastic back whistle ye-compact yindlela esebenzayo yokusombulula i-delamination.
2. I-phenomenon of uncompressed (i-particles eboniswayo) iya kwenzeka kwakhona ngexesha loxinzelelo lwe-carbide ene-cemented.
Ngenxa yokuba ubungakanani beepores ze-compact zikhulu kakhulu, azikwazi ukunyamalala ngokupheleleyo ngexesha lenkqubo ye-sintering, okukhokelela kwiipores ezikhethekileyo eziseleyo kumzimba odibeneyo.Iipilisi zinzima kakhulu, iipelisi zinqabile, kwaye izinto ezikhululekile zikhulu kakhulu;iipellets ezikhululekileyo zisasazwa ngokulinganayo kwi-cavity, kwaye ubunzima beyunithi buphantsi.inokubangela ukungaxininiswa.
3. Enye into eqhelekileyo yokucinezela inkunkuma kwi-cemented carbide pressing kukuqhekeka
Isenzeko sokwaphuka kwengingqi okungaqhelekanga kwi-compact kuthiwa yi-crack.Ngenxa yokuba uxinzelelo lwe-tensile ngaphakathi kwi-compact lukhulu kunamandla obunzima be-compact.Uxinzelelo lwangaphakathi lwe-compact luvela kuxinzelelo lwangaphakathi lwe-elastic.Izinto ezichaphazela i-delamination nazo zichaphazela ukuqhekeka.La manyathelo alandelayo anokuthathwa ukunciphisa ukwenzeka kweentanda: ukwandisa ixesha lokubamba okanye ucinezele amaxesha amaninzi, ukunciphisa uxinzelelo, ubunzima beyunithi, ukuphucula ukubunjwa kokubumba kunye nokwandisa ngokufanelekileyo ubukhulu bobumba, ukukhawulezisa isantya sokubunjwa, ukwandisa i-mold. i-ejenti yokubumba, kunye nokwandisa ubuninzi bezinto eziphathekayo.
Yonke inkqubo yokuvelisa i-carbide enesamente ibaluleke kakhulu.I-Zhuzhou Chuangrui Cemented Carbide Co., Ltd. ikhethekileyo kwimveliso ye-carbide enesamente iminyaka eyi-18.Ukuba unayo nayiphi na imibuzo malunga nokuveliswa kwe-carbide, nceda ubeke ingqalelo kwiwebhusayithi esemthethweni kaChuangrui.
