Qhov pib tawv ntawm cov hlau manganese siab yog qis heev, tsuas yog 220-250 HV, tab sis tus yam ntxwv ntawm cov hlau manganese siab yog tias qhov nyuaj dua nws hnav, qhov nyuaj dua nws yog, thiab qhov nyuaj tuaj yeem ncav cuag 600 HV tom qab lub sijhawm siv.
Yuav tsum muaj txoj kev siv hlau uas muaj manganese ntau los tiv taus kev hnav. 1. Qhov nyuaj pib yog siab. 2. Cia kom qhov tuab ua haujlwm ntawm hlau uas muaj manganese ntau nce ntxiv kom nws lub zog tiv taus kev hnav muaj peev xwm siv tau.
Cov hlau manganese yog cov khoom siv mos mos, nws qhov nyuaj pib yog li 220-250 HV, qhov tob ntawm cov txheej tawv tawv yog ntawm 10-15 hli, thiab qhov nyuaj hauv kev sib tsoo ntxhib tuaj yeem ncav cuag 600 HV. Hauv cov ntawv thov sib tsoo zoo, cov txheej tawv tawv yog nyias dua, thiab qhov nyuaj feem ntau yog li 350-500 HV.
Txoj kev ntseeg siab tshaj plaws los xyuas qhov hnav tsis kam ntawm cov hlau manganese siab yog kev tshuaj xyuas metallographic ntawm cov khoom tiav thiab tom qab kev kho cua sov. Cov tshuaj lom neeg ib txwm muaj tsuas yog qhia tau tias cov cim qhia lub cev thiab tshuaj lom neeg. Cov khoom siv kho tshuab tsis tuaj yeem npaj los piav qhia nws qhov hnav tsis kam. Feem ntau, nws yog qhov ntsuas qhov nyuaj pib uas tuaj yeem siv tau.
Kev kho cua sov yog lwm kauj ruam tseem ceeb los xyuas kom meej tias cov khoom ua tau zoo thiab muaj zog. Cov duab ntawm lub chamber crushing muaj feem cuam tshuam loj rau kev ua haujlwm ntawm lub crusher thiab lub neej ua haujlwm ntawm cov khoom hnav.
