Kev xaiv cov khoom siv rauDTH laum khoom
1. Txhawm rau txhim kho hnav tsis kam thiab ua kom muaj kev cuam tshuam, lubDTH laum ntsiscov khoom siv yog xaiv kom muaj lub hardness siab dua. Cov khoom siv yuav tsum muaj lub zog tawg, lub zog qaug zog, thiab lub zog tawg kom tiv thaiv kev tawg thiab qaug zog.
2. DTH laum cov khoom muaj siab hardenability. Txhim khu lub zog tawm los ntawm lub zog thiab lub zog ceev ntawm lub qhov rau lub khawm carbide yog qhov zoo. Tsis tas li ntawd, nws ua rau kom cov tub ntxhais tawm dag zog thiab durability.
3. Nws muaj peev xwm tiv taus corrosion thaum raug cov kua thiab roj hauv cov pob zeb hauv av.
4. Cov khoom siv hardness yog ruaj khov thiab nyuaj rau soften ntawm qhov kub thiab txias.
5. Muaj zog txheej txheem kev ua tau zoo, nrog rau kev muaj zog forging, thiab lwm yam.
6. Zoo heev metallurgical zoo, homogeneous lub koom haum, cov ntsiab lus phosphorus tsawg, ob peb impurities, thiab homogenous carbide.
Hauv kev xaus, muaj zog dynamic load zog thiab tshwj xeeb hnav tsis kam yuav tsum tau txiav txim siab thaum xaiv cov khoom siv rau DTH laum khoom. Txhawm rau txias DTH laum cov khoom thiab tshem tawm pob zeb slag, kev tsim kho yuav tsum ua kom lub siab ntawm huab cua mus rau hauv lub qhov hauv qab. Daim ntawv yog ncaj nraim thiab yooj yim los tsim. Txhawm rau ua kom muaj txiaj ntsig ntawm kev cuam tshuam hluav taws xob, qhov sib piv ntawm qhov hnyav ntawm DTH laum khoom rau qhov hnyav ntawm lub piston yuav tsum nyob ze 1.
