Cov qauv kev xaiv rauj hniav rau cov khoom sib txawv

Feem ntau suav nrog cov khoom siv thiab kev siv tau. Hauv qab no yog kev tshuaj xyuas ntawm ntau yam khoom siv rauj hniav thiab lawv cov khoom siv:

Tsawg carbon steel: Tsawg carbon steel rauj hniav yog tsim rau cov khoom siv crushing, xws li nplej, straw, thiab lwm yam. Nws qhov zoo dua yog tus nqi qis, tab sis qis hnav tsis kam thiab hardness, ua rau nws haum rau tuav cov ntaub ntawv softer.

Cov pa roj carbon nruab nrab: Cov pa roj carbon steel rauj nruab nrab cov hniav muaj qhov zoo hardness thiab hnav tsis kam, haum rau cov khoom siv nrog cov tawv tawv, xws li cov ceg ntoo, cov ceg ntoo me me, thiab lwm yam. Nws muaj cov kav ntev, tab sis tus nqi kuj tseem siab.

Cov cam khwb cia hlau tshwj xeeb: Cov cam khwb cia hlau tshwj xeeb yog tsim rau kev ua cov ntaub ntawv nyuaj xws li cov pob txha, ores, thiab lwm yam. Hom rauj no muaj kev hnav zoo, tab sis nws nyuaj rau kev ua haujlwm.

Kev kho mob quenching: Rauj cov khoom uas tau ua tiav kev kho mob quenching muaj zog dua thiab tsim nyog rau kev ua cov khoom siv tawv tawv xws li txiv ntoo, pob txha, thiab lwm yam. Nws hnav tsis kam thiab kev pabcuam lub neej ntev.

Carburizing thiab quenching: Cov rauj cov khoom kho nrog carburizing thiab quenching muaj zog dua thiab hnav tsis kam, thiab tsim nyog rau kev ua cov ntaub ntawv nyuaj heev xws li pob zeb, ores, thiab lwm yam.

Tungsten carbide: Tungsten carbide rauj tam sim no yog ib qho ntawm cov khoom siv nyuaj tshaj plaws nyob rau hauv kev ua lag luam, haum rau kev ua cov ntaub ntawv nyuaj heev xws li pob zeb, ores, thiab lwm yam. Nws hnav tsis kam thiab kev pab cuam lub neej ntev heev, tab sis tus nqi kuj yog siab heev.

Qhov zoo thiab qhov tsis zoo ntawm rauj hniav ua los ntawm cov khoom sib txawv yog raws li hauv qab no:

Tsawg carbon steel: Tsawg tus nqi, tab sis tsis tshua muaj hnav tsis kam thiab hardness.

Nruab nrab carbon steel: siab hardness thiab durability, tab sis tus nqi siab.

Tshwj xeeb cam khwb cia hlau: zoo hnav tsis kam, tab sis nyuaj rau txheej txheem.

Kev kho quenching: siab hardness thiab kev pab lub neej ntev.

Carburizing thiab quenching: tsis tshua muaj siab hardness, kev pab lub neej ntev, tab sis tus nqi siab.

Tungsten carbide: muaj qhov hardness siab tshaj plaws thiab lub neej ua haujlwm ntev, tab sis tus nqi siab tshaj.

Kev xaiv cov khoom siv rauj tsim nyog yuav tsum tau txiav txim siab txog yam xws li cov khoom siv hardness, kev ua haujlwm, thiab tus nqi.
