Kub dov hnav-resistant pob steel

Hauv thaj chaw ntawm kev lag luam, qhov kev thov rau cov khoom siv ruaj khov thiab hnav-tiv taus yog qhov tseem ceeb, tshwj xeeb tshaj yog nyob rau hauv cov teb uas muaj zog abrasive thiab hnyav hnyav. Ib qho khoom siv uas tau txais txiaj ntsig zoo hauv ntau qhov kev lag luam yog kub-kuav los tiag hnav-resistant pob steel. Cov hlau tshiab no sawv cev rau txoj kev loj hlob tseem ceeb hauv cov khoom siv engineering, muab qhov tshwj xeeb hardness, toughness, thiab tsis kam mus rau abrasion, ua rau nws yog ib qho kev xaiv zoo tshaj plaws rau cov ntawv thov uas lub neej ntev thiab kev ntseeg siab yog qhov tseem ceeb.

Kub-dov hnav-resistant pob steel yog ib hom tshwj xeeb ntawm cov hlau engineered los tiv thaiv qhov nruj ntawm qhov chaw abrasive, xws li mining, kev tsim kho, thiab kev tsim cov txheej txheem cuam tshuam nrog crushing thiab sib tsoo. Cov txheej txheem tsim khoom yuav raug xa cov hlau mus rau qhov kub siab thaum kub dov, ua raws li kev tswj kom txias, uas muab cov cuab yeej tshwj xeeb thiab cov khoom siv hlau rau cov khoom siv. Cov txheej txheem ntau lawm no ua rau cov hlau alloy nrog txhim kho hardness thiab hnav tsis kam, teeb nws sib nrug los ntawm cov pa hlau.

Cov yam ntxwv tseem ceeb uas paub qhov txawv ntawm qhov kub-dov hnav-tiv taus pob hlau yog nws qhov nyuaj heev, feem ntau ntsuas ntawm Rockwell nplai. Qhov tshwj xeeb hardness no tau ua tiav los ntawm kev ua tib zoo xaiv cov ntsiab lus alloying, kev kho cua sov, thiab kev tswj xyuas meej ntawm cov txheej txheem tsim khoom. Cov hlau lub microstructure yog tsim los rau kev sib koom ua ke nyuaj, xws li carbides, uas ua rau nws muaj peev xwm tiv taus abrasive hnav, cuam tshuam, thiab hnyav hnyav.

Daim ntawv thov ntawm kub-dov hnav-resistant pob steel muaj ntau haiv neeg thiab nthuav dav thoob plaws ntau qhov kev lag luam. Hauv kev ua haujlwm mining, cov pob hlau no tau siv rau hauv kev sib tsoo thiab sib tsoo, qhov twg cov ore raug txo kom zoo dua. Ib yam li ntawd, kev lag luam koom nrog hauv kev tsim cov cement, lub zog tsim hluav taws xob, thiab kev ua tshuaj lom neeg tau txais txiaj ntsig los ntawm kev hnav zoo tshaj ntawm cov pob hlau no hauv ntau lub tshuab thiab khoom siv.

Tsis tas li ntawd, kev siv cov kub-kuav los tiag hnav-tiv taus pob steel pab txhawb kev ua haujlwm tau zoo thiab tus nqi-zoo hauv cov txheej txheem kev lag luam los ntawm kev txo qis sijhawm thiab kev saib xyuas cov nqi cuam tshuam nrog cov khoom siv. Lub neej ntev ntawm cov pob hlau no txhais ua kev pabcuam txuas ntxiv rau cov tshuab, thaum kawg txhim kho tag nrho cov khoom tsim tau thiab cov txiaj ntsig ntawm kev lag luam.

Hauv kev xaus, kub-dov hnav-resistant pob steel sawv ua ib qho pov thawj rau kev nce qib hauv cov ntaub ntawv kev tshawb fawb, muab kev daws teeb meem rau cov teeb meem tshwm sim los ntawm ib puag ncig abrasive hauv ntau hom kev lag luam. Nws qhov tshwj xeeb sib xyaw ua ke ntawm hardness, toughness, thiab hnav tsis kam ua rau nws yog ib qho tseem ceeb ntawm cov khoom siv thiab cov khoom siv uas cov khoom siv tau ntev yog tsis sib tham. Raws li kev lag luam txuas ntxiv mus ntxiv, lub luag haujlwm ntawm kub-dov hnav-tiv taus pob hlau zoo li yuav nthuav dav, muab cov kev daws teeb meem mus ntev rau qhov kev xav tau ntawm kev siv niaj hnub no.
