Neeg kho tshuab hniav thiab lawv qhov kev ua tau zoo
Cov tshuab kho tshuab yog cov kev txiav cov cuab yeej rau kev ua cov khoom siv raw thiab cov khoom lag luam hauv kev lag luam xws li papermaking, luam ntawv, thiab ua ntoo. Lawv los nyob rau hauv ntau ntau yam ntawm ntau yam, tau siv dav, thiab lawv cov kev siv tau nce. Neeg kho tshuab hniav yog nyias-hniav cov cuab yeej rau txiav cov ntaub ntawv tsis yog xim hlau. Tom qab kev kho cua sov, lawv yuav tsum muaj kev ua haujlwm zoo dua. Lawv yuav tsum muaj lub hardness, tawv, hnav tsis kam thiab qee yam kub nyhiab, nrog rau kev qaug zog ua kom tsis kam thiab carbide peeting ua. Tshwj xeeb tshaj yog cov ntoo ua kom qeeb cutters thiab cov cuab yeej txiav, cov cai yuav tsum tau yog siab dua. Ntawm tam sim no, cov hniav hlau ntawm cov khoom siv txiav qeeb thiab cov cav ntoo txiav hauv tsev thiab txawv teb chaws steel hlau. Raws li nws muaj pes tsawg leeg, nws zwm rau cov roj carbon ntau-alloy-alloy-alloy-alloy-alloy Hnav tsis kam thiab cuam tshuam tsis kam thaum lub sijhawm txiav. Txhawm rau txhawm rau txhim kho kev ua tau zoo ntawm kev txiav av thiab cov tsev luam ntawv thiab cov tuam txhab lag luam txawv teb chaws tseem txuas ntxiv thiab sim nrog cov hniav hlau tshiab.
Cov kev ua tau zoo ntawm cov neeg kho tshuab hluav taws xob suav nrog cov ntsej muag zoo, tsis muaj chritness, thiab kev qaug zog, kub tsis kam thiab ua kom tawv nqaij tawv, tab sis tsis yog qhov sib npaug. Qhov ntse ntawm cov hniav muaj qhov ncaj qha rau lub hardness thiab kog lub zog ntawm cov hniav hniav sib tsoo thiab hniav sib tsoo. Cov hnav tsis kam ntawm cov hniav yog cuam tshuam nrog cov hnav tsis kam ntawm matrix thiab cov ntug ntawm carbides ntawm hniav. Tus nqi tsim nyog ntawm cov neeg saib xyuas cov khoom lag luam thiab lawv lub hardness kuj tseem ceeb heev. Cov hniav tsis nti lossis caws vim tias cov kev ua kom muaj zog, tawv tawv, ua kom qaug zog, ua kom qaug zog, ua kom qaug zog, ua kom muaj zog, ua kom qaug zog, ua kom muaj zog ntawm cov qauv hniav tsis tuaj yeem ua tiav ntawm cov qauv hauv tebchaws.
