Cemented carbide yog cov hmoov hlau metallurgy khoom ua los ntawm carbide (WC, TiC) micron-theem hmoov ntawm siab hardness refractory hlau raws li lub ntsiab tivthaiv, nrog cobalt (Co) los yog npib tsib xee (Ni), molybdenum (Mo) raws li cov binder, txaus siab rau. lub tshuab nqus tsev vacuum los yog hydrogen reduction cub.
Classification thiab Qib
①Tungsten thiab Cobalt Cemented Carbide
Cov khoom tseem ceeb yog tungsten carbide (WC) thiab binder cobalt (Co).
Qib yog tsim los ntawm "YG" ("nyuaj, cobalt" hauv Hanyu Pinyin) thiab feem pua ntawm cov ntsiab lus cobalt nruab nrab.
Piv txwv li, YG8, txhais tau tias qhov nruab nrab WCo = 8%, thiab tus so yog tungsten carbide carbide.
②Tungsten, titanium thiab cobalt cemented carbide
Cov khoom tseem ceeb yog tungsten carbide, titanium carbide (TiC) thiab cobalt.
Qib yog tsim los ntawm "YT" ("nyuaj, titanium" hauv Hanyu Pinyin) thiab cov ntsiab lus nruab nrab ntawm titanium carbide.
Piv txwv li, YT15, txhais tau tias qhov nruab nrab WTi = 15%, tus so yog tungsten carbide thiab cobalt ntsiab lus ntawm tungsten titanium cobalt carbide.
③Tungsten-titanium-tantalum (niobium) hom carbide
Cov khoom tseem ceeb yog tungsten carbide, titanium carbide, tantalum carbide (los yog niobium carbide) thiab cobalt.Hom carbide no tseem hu ua general-purpose carbide lossis universal carbide.
Lub teb chaws tsim khoom loj
Muaj ntau tshaj li 50 lub teb chaws nyob hauv lub ntiaj teb uas tsim cov cemented carbide, thiab tag nrho cov zis tuaj yeem ncav cuag 27,000-28,000t-, lub teb chaws tsim khoom tseem ceeb yog Asmeskas, Russia, Sweden, Tuam Tshoj, Lub teb chaws Yelemees, Nyiv, UK, Fabkis, thiab lwm yam. cemented carbide kev ua lag luam yog qhov pib hauv lub xeev saturation, thiab kev sib tw ua lag luam yog qhov hnyav heev.Tuam Tshoj txoj kev lag luam cemented carbide tau tsim nyob rau xyoo 1950s, thiab nws tau tsim sai heev los ntawm xyoo 1960 txog rau xyoo 1970.Nyob rau hauv thaum ntxov 1990s, Tuam Tshoj tag nrho cov peev xwm ntawm cemented carbide mus txog 6000t, thiab tag nrho cov khoom ntawm cemented carbide mus txog 5000t, qeb thib 3 hauv ntiaj teb tom qab Russia thiab Tebchaws Meskas.
Carbide rods yog carbide txiav cov cuab yeej, uas yog tsim rau sib txawv ntxhib sib tsoo tsis, txiav cov ntaub ntawv raws li zoo raws li cov ntaub ntawv uas tsis yog-hlau.Nws yog siv nyob rau hauv cov pa tsis siv neeg thiab semi-automatic lathes, thiab lwm yam.
Ua ntej ntawm tag nrho cov, carbide bar muaj ntau yam kev siv nyob rau hauv lub teb ntawm machining.Nws tuaj yeem siv los ua cov cuab yeej tig ceev, cov cuab yeej milling, cobalt taub hau, cov cuab yeej reaming thiab lwm yam cuab yeej kos duab, uas tuaj yeem txhim kho qhov txiav ceev.
Nws tuaj yeem txhim kho kev txiav ceev thiab ua haujlwm tau zoo, txo cov nqi ua haujlwm, thiab tseem ua kom qhov tseeb thiab qhov zoo ntawm cov khoom siv.
Thib ob, hauv kev ua cov khoom siv, cov cemented carbide rods kuj muaj cov ntawv thov tseem ceeb.
Nws tuaj yeem ua cov roj laum khoom, pob zeb laum khoom, txiav cov khoom thiab lwm yam kev tuag, uas tuaj yeem ua haujlwm ruaj khov nyob rau hauv ib puag ncig hnyav ntawm lub zog siab, siab hardness thiab siab siab, txhim khu kev ua haujlwm zoo thiab zoo.
Tsis tas li ntawd, cov cemented carbide rods kuj tseem ua lub luag haujlwm tseem ceeb hauv kev ua liaj ua teb.Nws tuaj yeem siv los ua cov cuab yeej drilling, thee drilling cov cuab yeej, geological drilling cov cuab yeej thiab lwm yam cuab yeej, uas tuaj yeem nqa tawm ntau hom kev drilling, drilling, txhaum kev tshawb nrhiav thiab lwm yam kev ua haujlwm nyob rau hauv qhov nyuaj thiab ntau qhov kev sib tshuam mining ib puag ncig, kom muaj kev nyab xeeb. thiab xyuas kom meej ntawm thaj chaw mining.
Feem ntau, carbide rods nrog siab hnav tsis kam, siab zog thiab kub kev ua tau zoo yog dav siv hauv machining, cov khoom ua, mining thiab lwm yam kev lag luam, uas tuaj yeem txhim kho cov kav ntev thiab kev ua haujlwm ntawm cov cuab yeej, thiab yog li ua tiav kev lag luam, txuag hluav taws xob thiab ib puag ncig. kev tiv thaiv kev txhim kho.
Nta:
Feem ntau siv rau hauv PCB laum khoom, ntau hom kawg mills, reamers, reaming xyaum, thiab lwm yam.;
- Kev siv ultra-fine specification sub-micron, zoo meej ua ke ntawm superb hnav tsis kam thiab cuam tshuam toughness;
- Resistance rau deformation thiab deviation;
- Tuam Tshoj tungsten Online muaj ntau lawm technology ntawm tungsten alloy round bar;
Yuav ua li cas "hloov" carbide round bar rau hauv cov cuab yeej carbide?Nrog rau kev txhim kho tas mus li ntawm qib kev lag luam, qhov kev xav tau zoo ntawm carbide round bar tseem nce ntxiv.Hauv kev lag luam high-precision machining, kev khiav tawm ntawm cov cuab yeej carbide muaj qhov cuam tshuam rau qhov raug ntawm cov khoom, thiab qib ntawm cov cuab yeej khiav tawm qhov ntsuas yog tsuas yog txwv los ntawm cylindrical Performance index ntawm carbide tuav.Nyob rau hauv cov txheej txheem ntau lawm ntawm carbide bar, lub cylindrical ntawm qhov txaus siab bar dawb paug yog cuam tshuam los ntawm cov khoom thiab hmoov metallurgy txheej txheem, yog li cylindrical tswj ntawm carbide zoo sib tsoo bar yog tsuas yog nyob rau hauv lub tom ntej ua thiab kev kho mob tshwj xeeb.Feem ntau, txoj kev ua haujlwm tseem ceeb ntawm carbide tuav yog nruab nrab-tsawg sib tsoo.Cov txheej txheem sib tsoo ntawm qhov chaw nruab nrab yog tsim los ntawm peb qhov chaw: kev sib tsoo lub log, kho lub log thiab cov khoom ua haujlwm, qhov kev sib tsoo lub log ua haujlwm ua haujlwm sib tsoo, lub log hloov kho tswj kev sib hloov ntawm cov khoom ua haujlwm thiab ua rau cov khoom ua haujlwm tshwm sim. ntawm tus nqi pub, thiab raws li tus neeg tuav haujlwm, uas txhawb nqa cov khoom ua haujlwm thaum lub sij hawm sib tsoo, peb qhov no tuaj yeem muaj ntau txoj hauv kev sib koom tes (tshwj tsis yog kev sib tsoo), txhua yam yog tib yam hauv txoj cai.
Cylindrical yog ib qho kev qhia dav dav los ntsuas qhov roundness thiab straightness ntawm lub bar.Lub cylindrical ntawm lub carbide bar feem ntau cuam tshuam los ntawm qhov chaw siab ntawm cov khoom ua haujlwm, tus nqi ntawm cov cuab yeej pub, kev pub ceev, thiab kev sib hloov ceev ntawm cov kev taw qhia log hauv nruab nrab-tsawg sib tsoo txheej txheem.Yog li tuav lub cylindrical Performance index kom cov carbide bar ntse "hloov" rau hauv cov cuab yeej zoo carbide.
