Yintoni tungsten carbide?

I-Tungsten carbide, okanye i-cemented carbide, ekwabizwa ngokuba yi-alloy eqinile, yamkelwa njengenye yezona zinto zinzima.s emhlabeni. Ngokwenene, yintsimbi, kodwa yimbumbaukukhutshwa I-tungsten, i-cobalt kunye nezinye isinyithi. Obona bunzima buphezulu be-tungsten carbide eyenziwe ngoku ijikeleze i-94 HRA, ilinganiswa ngendlela ye-Rockwell A. Enye yezona zinto zibalulekileyos yetungsten carbide yitungsten, eneyona ndawo iphezulu yokunyibilika kuzo zonke iintsimbi. I-Cobalt isebenza njenge-binder kule matrix yensimbi kunye nokuphuculas amandla okugoba e-tungsten carbide. Ngenxa yokusebenza okuphezulu kwe-tungsten carbide, yinto efanelekileyo kumashishini amaninzi, afana ne-tungsten carbide inserts, i-carbide rods kunye ne-end mill yezixhobo zokusika ze-CNC; ukusika iincakuba zokusika iphepha, ukusika amakhadibhodi, njl. Isihloko se-tungsten carbide siyafa, isikhonkwane siyafa, umzobo uyafa ngenxa yesicelo sokumelana nokunxiba; I-tungsten i-carbide yabona iingcebiso, iipleyiti ze-carbide, ii-carbide strips zokusika kunye nokunxiba isicelo; amaqhosha e-tungsten carbide, i-HPGR studs, i-carbide mining efakwe kwiindawo zokomba. Impahla ye-tungsten carbide isetyenziswa ngokubanzi kangangokuba ikwabizwa ngokuba“amazinyo kumashishini”.

Yintoni inkqubo yokuvelisa i-tungsten carbide?

1. Isinyathelo sokuqala sokwenza imveliso ye-tungsten carbide, kukwenza umgubo. Umgubo ngumxube weWC kunye neCobalt, zixutywe kunye kumlinganiselo othile. Umzekelo, ukuba abathengi bafuna i-tungsten carbide heading dies, bafuna i-carbide grade YG20, ubuninzi beekhilogram ezili-100. Emva koko umenzi womgubo uya kuxuba malunga ne-18kgs ye-Cobalt powder kunye ne-80kgs ye-WC powder, ibhalansi ye-2kgs yezinye i-metal powders eziya kongezwa ngokweresiphi yenkampani ye-YG20 grade. Zonke ii powders ziya kufakwa koomatshini bokungqusha. Kukho amandla awohlukeneyo oomatshini bokungqusha, abanje nge5kgs kwiisampulu, 25kgs, 50kgs, 100kgs, okanye ezinkulu.

2. Emva kokuxuba umgubo, inyathelo elilandelayo kukutshiza kunye nokomisa. KwiNkampani yeCarbide yaseZhuzhou engcono yeTungsten, kusetyenziswa inqaba yokutshiza, eya kuphucula ukusebenza komzimba kunye neekhemikhali ze-tungsten carbide powder. Umgubo owenziwe nge-Spray tower unomsebenzi ongcono kakhulu kunabanye oomatshini. Emva kokugqiba le nkqubo, umgubo ungaphakathi“ukulungele-ukucofa” imeko.

3. Umgubo uya kucinezelwa emva kwe“ukulungele-ukucofa” umgubo uvavanywa Kulungile. Kukho iindlela ezahlukeneyo zokucinezela, okanye sithetha iindlela ezahlukeneyo zokwenza iimveliso ze-tungsten carbide. Ngokomzekelo, ukuba i-factory ivelisa i-tungsten carbide saw tips, umatshini wokushicilela ngokuzenzekelayo uya kusetyenziswa; ukuba i-tungsten carbide die enkulu iyafuneka, umatshini wokucinezela wesiqingatha-manual uya kusetyenziswa. Kukho nezinye iindlela zokwenza iimveliso ze-tungsten carbide, njengokucofa okubandayo kwe-isostatic (igama elifutshane yi-CIP), kunye noomatshini bokukhupha.

4. I-Sintering yinkqubo emva kokucinezela, ikwayinkqubo yokugqibela yokuvelisa i-tungsten carbide metal enokuthi isetyenziswe njengobunzima obuphezulu kunye namandla aphezulu ensimbi yobunjineli yokusika, ukunxiba, ukugrumba, okanye ezinye izicelo. Ubushushu be-sintering buphezulu ukuya kwi-1400 centigrade. Kwimilo eyahlukeneyo, iqondo lobushushu liya kuba nolwahlulo oluthile. Kwiqondo lokushisa eliphezulu, i-binder inokudibanisa i-powder WC kwaye yenza isakhiwo esinamandla. Inkqubo ye-sintering inokwenziwa kunye okanye ngaphandle komatshini woxinzelelo lwegesi ye-isostatic ephezulu (HIP).

Le nkqubo ingentla inkcazo elula yenkqubo yokuvelisa i-carbide enesamente. Nangona ibonakala ilula, imveliso ye-tungsten carbide lishishini lokuqokelela ubuchwephesha obuphezulu. Akulula ukuvelisa iimveliso ze-tungsten carbide ezifanelekileyo. I-Tungsten luhlobo lwesixhobo esingahlaziywayo, xa sele sisetyenzisiwe, akunakwenzeka ukwenza kwakhona ngexesha elifutshane. Buxabise ubutyebi obuxabisekileyo, qiniseka ukuba yonke ibhetshi yeemveliso ze-tungsten carbide ifanelekile ngaphambi kokuba ifike ezandleni zabathengi, sesinye sezizathu eziphambili ezisityhalayo ukuba senze ngcono. Qhubeka uhamba, qhubeka uphucula!
