Cemented carbide yog cov khoom siv hlau ua los ntawm cov khoom siv tawv tawv ntawm cov hlau refractory thiab cov hlau sib txuas los ntawm cov txheej txheem hmoov metallurgy.Nws muaj cov yam ntxwv ntawm siab hardness, hnav tsis kam, lub zog thiab toughness.Vim nws cov khoom tshwj xeeb, nws feem ntau siv los ua cov cuab yeej pob zeb drilling, cov cuab yeej tsuas, cov cuab yeej drilling, ntsuas cov cuab yeej thiab lwm yam.Nws yog dav siv nyob rau hauv roj av thiab natural gas, tshuaj lom neeg kev lag luam, kev tsim kho machinery, dej tswj thiab lwm yam teb.Cemented carbide yog cov khoom siv los ntawm cov hmoov metallurgy.Niaj hnub no, Chuangrui Xiaobian yuav qhia koj ntau yam teeb meem loj uas peb feem ntau ntsib hauv cov txheej txheem nias, thiab piav qhia luv luv vim li cas.
1. Feem ntau nias pov tseg hauv cov txheej txheem cemented carbide yog delamination
Qhov tshwm sim raws ntug ntawm lub siab thaiv, ntawm ib lub kaum ntse ntse rau qhov siab saum npoo, tsim kom zoo nkauj interface yog hu ua delamination.Feem ntau ntawm cov txheej txheem pib ntawm cov ces kaum thiab txuas mus rau hauv lub compact.Yog vim li cas rau delamination ntawm lub compact yog lub elastic sab hauv kev nyuaj siab los yog elastic nro nyob rau hauv lub compact.Piv txwv li, cov ntsiab lus cobalt ntawm qhov sib tov yog qhov tsawg, qhov hardness ntawm carbide yog siab, cov hmoov los yog particle yog finer, tus neeg sawv cev molding yog me me los yog cov khoom faib tsis sib xws, qhov sib tov yog ntub los yog qhuav heev, Lub zog nias yog loj dhau, lub ntsuas qhov hnyav yog qhov loj heev, thiab lub zog nias yog siab dhau.Cov duab thaiv yog qhov nyuaj, cov pwm tiav yog qhov tsis zoo, thiab lub rooj saum npoo tsis sib xws, uas tuaj yeem ua rau delamination.
Yog li ntawd, kev txhim kho lub zog ntawm compact thiab txo cov kev ntxhov siab sab hauv thiab elastic rov qab whistle ntawm lub compact yog ib txoj kev zoo los daws cov delamination.
2. Qhov tshwm sim ntawm uncompressed (pom cov khoom) kuj yuav tshwm sim thaum lub sij hawm nias txheej txheem ntawm cemented carbide.
Vim hais tias qhov loj ntawm lub pores ntawm lub compact loj heev, nws tsis tuaj yeem ploj mus tag nrho thaum lub sij hawm sintering txheej txheem, uas ua rau cov pores tshwj xeeb ntxiv nyob rau hauv lub cev sintered.Cov pellets nyuaj dhau, cov pellets yog ntxhib heev, thiab cov khoom xoob yog loj dhau;cov pellets xoob yog unevenly faib nyob rau hauv kab noj hniav, thiab chav tsev qhov hnyav yog tsawg.yuav ua rau uncompressed.
3. Lwm qhov tshwm sim ntawm cov khib nyiab ntau hauv cemented carbide nias yog tawg
Qhov tshwm sim ntawm qhov tsis sib xws hauv zos tawg hauv lub compact yog hu ua tawg.Vim hais tias lub tensile kev nyuaj siab nyob rau hauv lub compact yog ntau tshaj lub tensile lub zog ntawm lub compact.Internal tensile kev nyuaj siab ntawm lub compact yog los ntawm elastic internal stress.Yam uas cuam tshuam rau delamination kuj cuam tshuam rau kev tawg.Cov kev ntsuas hauv qab no tuaj yeem siv los txo qhov tshwm sim ntawm cov kab nrib pleb: ncua lub sijhawm tuav lossis nias ntau zaus, txo qhov siab, chav ntsuas qhov hnyav, txhim kho pwm tsim thiab tsim kom muaj qhov tuab ntawm pwm, ua kom lub demoulding ceev, nce qhov molding tus neeg sawv cev, thiab nce qhov ceev ntawm cov khoom.
Tag nrho cov txheej txheem ntawm cemented carbide yog qhov tseem ceeb heev.Zhuzhou Chuangrui Cemented Carbide Co., Ltd. tau tshwj xeeb hauv cemented carbide ntau lawm rau 18 xyoo.Yog tias koj muaj lus nug txog kev tsim cov cemented carbide, thov xyuam xim rau Chuangrui lub vev xaib official.
