Isetyenziswa ngokuqhelekileyoiikhabhidi ezenziwe ngesamentezihlulwe zibe ziindidi ezintathu ngokubunjwa kwazo kunye neempawu zokusebenza: i-tungsten-cobalt, i-tungsten-titanium-cobalt, kunye ne-tungsten-titanium-tantalum (niobium). Eyona nto isetyenziswa kakhulu kwimveliso yi-tungsten-cobalt kunye ne-tungsten-titanium-cobalt cemented carbides.
(1) I-tungsten-cobalt ye-cemented carbide
Amacandelo aphambili yi-tungsten carbide (WC) kunye ne-cobalt. Igama lomkhiqizo limelwe yikhowudi ye-YG (i-prefixed yi-pinyin yaseTshayina ethi "hard" kunye ne "cobalt"), ilandelwa yipesenti yexabiso le-cobalt content. Ngokomzekelo, i-YG6 imele i-tungsten-cobalt cemented carbide enomxholo we-cobalt we-6% kunye nomxholo we-tungsten we-carbide we-94%.
(2) I-tungsten titanium cobalt carbide
Amacandelo aphambili yi-tungsten carbide (WC), i-titanium carbide (TiC) kunye ne-cobalt. Igama lomkhiqizo limelwe yikhowudi ye-YT (isiqalo se-pinyin yaseTshayina "enzima" kunye ne "titanium"), ilandelwa yipesenti yexabiso le-titanium carbide content. Ngokomzekelo, i-YT15 imele i-tungsten-titanium-cobalt carbide kunye nomxholo we-titanium carbide we-15%.
(3) I-tungsten titanium tantalum (niobium) uhlobo lwe-cemented carbide
Olu hlobo lwe-cemented carbide lukwabizwa ngokuba yi-carbide ye-cemented general okanye i-universal cemented carbide. Amacandelo ayo aphambili yi-tungsten carbide (WC), i-titanium carbide (TiC), i-tantalum carbide (TaC) okanye i-niobium carbide (NbC) kunye ne-cobalt. Igama lebhrendi limelwe yikhowudi enguYW (iprefixed yi-pinyin yaseTshayina ethi "hard" kunye ne "wan") elandelwa yinombolo ye-ordinal.
Ukusetyenziswa kwekhabhide enesamente
(1) Isixhobo sezixhobo
I-Carbide yeyona nto isetyenziswa kakhulu izixhobo zesixhobo kwaye ingasetyenziselwa ukwenza izixhobo zokuguqula, abasiki be-milling, abacwangcisi, i-drill bits, njl. Phakathi kwabo, i-tungsten-cobalt carbide ilungele ukulungiswa kwe-chip emfutshane yesinyithi esinentsimbi kunye nesinyithi esingenawo isinyithi kunye nokucutshungulwa kwezinto ezingezizo zetsimbi, ezifana nentsimbi, i-cast cast, ithusi, i-bakelite, njl. I-tungsten-titanium-cobalt carbide ifanelekile kwi-long-chip processing yesinyithi se-ferrous njengentsimbi. Ukulungiswa kwe-chip. Phakathi kwama-alloys afanayo, abo banomxholo ongaphezulu we-cobalt bafanelekile kumatshini obunzima, ngelixa abo banomxholo omncinci we-cobalt bafanelekile ukugqiba. Ubomi bokucutshungulwa kwe-carbide yenjongo jikelele kwizinto ezinzima-kumatshini ezifana nentsimbi engenasici ide kakhulu kunenye i-carbide.Intsimbi yeCarbide
(2) Izinto zokungunda
ICarbide isetyenziswa ikakhulu njengoko umzobo obandayo uyafa, ukubetha ngenqindi okubandayo kuyafa, i-extrusion ebandayo iyafa, i-pier ebandayo iyafa kunye nomnye umsebenzi obandayo uyafa.
Ngaphantsi kweemeko zokusebenza zokunxiba zokuthwala impembelelo okanye impembelelo enamandla, ukuqhelekileyo kwei-carbide ebandayoIsihloko siyafa kukuba i-carbide ene-cemented iyadingeka ukuba ibe nokuqina kwempembelelo elungileyo, ukuqina kokwaphuka, amandla okudinwa, amandla okugoba kunye nokuxhathisa okulungileyo. Ngesiqhelo, amabanga aphakathi kunye aphezulu cobalt kunye medium and coarse grain alloy alloy amabanga akhethiweyo, njenge YG15C.
Ngokuqhelekileyo, ubudlelwane phakathi kokumelana nokunxiba kunye nokuqina kwe-carbide ene-cemented iyaphikisana: ukunyuka kokumelana nokunxiba kuya kukhokelela ekunciphiseni ukuqina, kwaye ukunyuka kokuqina kuya kubangela ukuhla kokuxhatshazwa kokugqoka. Ngoko ke, xa ukhetha amabakala adibeneyo, kuyimfuneko ukuhlangabezana neemfuno ezithile zokusetyenziswa ngokusekelwe kwizinto zokucubungula kunye neemeko zokusebenza.
Ukuba ibakala elikhethiweyo liqhelene nokuqhekeka kwangaphambili kunye nomonakalo ngexesha lokusetyenziswa, kufuneka ukhethe ibakala elinobunzima obuphezulu; ukuba ibakala elikhethiweyo lijongene nokunxiba kwangaphambili kunye nokulimala ngexesha lokusetyenziswa, kufuneka ukhethe ibakala elinobunzima obuphezulu kunye nokumelana nokunxiba okungcono. . La mabanga alandelayo: YG6C, YG8C, YG15C, YG18C, YG20C ukusuka kwesobunxele ukuya kwesokudla, ubunzima buyancipha, ukuxhatshazwa kokugqoka kuyancipha, kwaye ukunyuka kwanda; ngokubhidana.
(3) Izixhobo zokulinganisa kunye namalungu angagugiyo
I-Carbide isetyenziselwa ukugquma komphezulu ongagugiyo kunye neenxalenye zezixhobo zokulinganisa, iibheringi ezichanekileyo zokusila, iipleyiti zesikhokelo sokusila esingenaziko kunye neentonga zesikhokelo, imiphezulu yeentambo kunye nezinye iindawo ezingagugiyo.
