I-carbide ene-cemented yimveliso ye-metallurgy yomgubo eyenziwe nge-carbide (WC, i-TiC) i-micron-level powder ye-high hardness refractory metals njengeyona nxalenye iphambili, kunye ne-cobalt (Co) okanye i-nickel (Ni), i-molybdenum (Mo) njenge-binder, enomdla i-vacuum furnace okanye isithando sokunciphisa i-hydrogen.
Ukuhlelwa kunye namaBanga
①Tungsten kunye neCobalt Cemented Carbide
Icandelo eliphambili yi-tungsten carbide (WC) kunye ne-binder cobalt (Co).
Ibakala liqulunqwe "YG" ("hard, cobalt" eHanyu Pinyin) kunye nepesenti yomxholo wecobalt ophakathi.
Umzekelo, i-YG8, ithetha i-avareji ye-WCo = 8%, kwaye enye i-tungsten carbide carbide.
②I-tungsten, i-titanium kunye ne-cobalt ye-cemented carbide
Amacandelo aphambili yi-tungsten carbide, titanium carbide (TiC) kunye ne-cobalt.
Ibakala lenziwe nge-"YT" ("hard, titanium" eHanyu Pinyin) kunye nomxholo ophakathi we-titanium carbide.
Umzekelo, i-YT15, ithetha i-avareji ye-WTi = 15%, enye i-tungsten carbide kunye nomxholo we-cobalt we-tungsten titanium cobalt carbide.
③Tungsten-titanium-tantalum (niobium) uhlobo lwe-carbide
Amacandelo aphambili yi-tungsten carbide, i-titanium carbide, i-tantalum carbide (okanye i-niobium carbide) kunye ne-cobalt.Olu hlobo lwe-carbide lukwabizwa ngokuba yi-carbide-purpose-purpose okanye i-universal carbide.
Amazwe aphambili avelisayo
Kukho amazwe angaphezu kwama-50 ehlabathini avelisa i-carbide ene-cemented, kwaye imveliso iyonke inokufikelela kwi-27,000-28,000t-, amazwe avelisa kakhulu yi-USA, iRashiya, iSweden, iChina, iJamani, iJapan, i-UK, iFransi, njl. Imarike ye-carbide enesamente ikwimeko yokugcwala, kwaye ukhuphiswano lwentengiso lubukhali kakhulu.Umzi mveliso weCarbide owenziwe ngesamente waseTshayina wasekwa ngasekupheleni kweminyaka yoo-1950, kwaye wakhula ngokukhawuleza ukusuka ngoo-1960 ukuya koo-1970.Ekuqaleni kweminyaka yoo-1990, umthamo wemveliso waseTshayina wekhabhide enesamente wafikelela kwi-6000t, kwaye imveliso epheleleyo ye-carbide enesamente yafikelela kwi-5000t, ibeka indawo yesi-3 kwihlabathi emva kweRashiya ne-United States.
Iintsimbi ze-carbide zizixhobo zokusika i-carbide, ezifanelekileyo kwiiparitha ezahlukeneyo zokugaya, izinto zokusika kunye nezinto ezingezizo zetsimbi.Isetyenziswe kwiileyile eziqhelekileyo ezizenzekelayo kunye ne-semi-automatic, njl.
Okokuqala, ibha ye-carbide inoluhlu olubanzi lwezicelo kwintsimi yomatshini.Ingasetyenziselwa ukwenza izixhobo zokuguqula isantya esiphezulu, izixhobo zokugaya, iintloko ze-cobalt, izixhobo zokubuyisela kunye nezinye izixhobo zokudweba, ezinokuphucula isantya sokusika.
Inokuphucula isantya sokusika kunye nokusebenza kakuhle, ukunciphisa iindleko zokucubungula, kunye nokuqinisekisa ukuchaneka kunye nomgangatho womgangatho weendawo ezinomatshini.
Okwesibini, kwintsimi yokulungiswa kwezinto, iintonga ze-carbide ze-cemented nazo zinezicelo ezibalulekileyo.
Inokwenza i-oil drill bits, i-rock drill bits, i-cut cut and other dies, enokugcina ukusebenza okuzinzile phantsi kwemeko enzima yamandla aphezulu, ukuqina okuphezulu kunye noxinzelelo oluphezulu, ngokufanelekileyo ukuphucula ukusebenza kakuhle kunye nomgangatho.
Ukongezelela, iintonga ze-carbide ze-cemented nazo zidlala indima ebalulekileyo kwintsimi yemigodi.Ingasetyenziselwa ukwenza izixhobo zokumbiwa kwemigodi, izixhobo zokugaya amalahle, izixhobo zokugaya i-geological kunye nezinye izixhobo, ezinokuthi ziqhube iintlobo ezahlukeneyo zokugaya, ukugaya, ukukhangela iimpazamo kunye nomnye umsebenzi kwindawo yokumbiwa kwemigodi eyinkimbinkimbi kunye ne-multi-intersection, ukuqinisekisa ukhuseleko. kunye nokufunyanwa ngokuchanekileyo kwendawo yemigodi.
Ngokubanzi, iintonga ze-carbide ezinokumelana nokunxiba okuphezulu, amandla aphezulu kunye nokusebenza kobushushu obuphezulu zisetyenziswa ngokubanzi kumatshini, ukusetyenzwa kwezinto, imigodi kunye nezinye iindawo, ezinokuphucula ukuqina kunye nokusebenza kakuhle kwezixhobo, kwaye ngaloo ndlela kufezekiswe ukusebenza kakuhle kweshishini, ukonga amandla kunye nokusingqongileyo. uphuhliso lokhuseleko.
Iimbonakalo:
Ikakhulu isetyenziswa kwi-PCB drill bits, iindidi ngeendidi zokusila, iireamers, ii-reaming drills, njl.;
- Ukusetyenziswa kwe-ultra-fine specication sub-micron, indibaniselwano egqibeleleyo yokuxhathisa okugqwesileyo kunye nokuqina kwempembelelo;
- Ukumelana nokuguqulwa kunye nokutenxa;
-I-tungsten yaseTshayina kwi-Intanethi inetekhnoloji ephuculweyo yemveliso ye-tungsten alloy round bar;
Indlela "yokuguqula" ibha ejikelezayo ye-carbide kwisixhobo se-carbide?Ngokuphuculwa okuqhubekayo kwinqanaba lezoshishino, iimfuno zomgangatho we-carbide round bar nazo ziyanda.Kwi-high-precision machining industry, ukukhutshwa kwezixhobo ze-carbide kuneempembelelo ezibulalayo ekuchanekeni kweemveliso, kwaye inqanaba lesixhobo sokukhupha isalathisi ngokuyinhloko lilinganiselwe yi-cylindrical index of carbide bar.Kwinkqubo yokuvelisa i-bar ye-carbide, i-cylindrical ye-bar enomdla engenanto ichaphazeleka yinkqubo yezinto kunye ne-powder metallurgy, ngoko ke ukulawulwa kwe-cylindrical ye-carbide yokugaya i-bar iphambili kwi-processing elandelayo kunye nonyango olukhethekileyo.Ngokubanzi, indlela ephambili yokucubungula imivalo ye-carbide yi-center-less grinding.Inkqubo yokugaya iphakathi iqulethwe ngamacandelo amathathu: ivili lokugaya, ivili lokulungelelanisa kunye nesibambi somsebenzi, apho ivili lokugaya lisebenza ngokwenene njengomsebenzi wokusila, ivili lokulungelelanisa lilawula ukujikeleza komsebenzi kwaye kubangela ukuba umsebenzi wenzeke. kwisantya sokutya, kwaye malunga nomphathi womsebenzi, oxhasa umsebenzi ngexesha lokugaya, ezi zintathu zinokuba neendlela ezininzi zokubambisana (ngaphandle kokuyeka ukugaya), zonke zifana nomgaqo.
I-Cylindrical isalathiso esibanzi sokulinganisa ukujikeleza kunye nokuthe tye kwebar.I-cylindrical yebar ye-carbide ichaphazeleka kakhulu kubude beziko lomsebenzi owenziweyo, isixa sesixhobo sokutya, isantya sokutya, kunye nesantya sokujikeleza kwevili lesikhokelo kwinkqubo yokugaya iziko.Ngoko bamba isalathisi se-cylindrical ukwenza ibha ye-carbide ngempumelelo "iguqulwe" kwisixhobo esiphezulu se-carbide.
