Yuav ua li cas txhawm rau txhim kho hardness ntawm cov khoom siv kho cua sov ntawm zaus quenching tshuab cuab yeej

40Cr khoom iav quenching, 2500-8000HZ nruab nrab zaus quenching tshuab cuab yeej, siv nruab nrab zaus nto induction, inductor yog quenching inductor raws tus hniav zawj, qhov nruab nrab cua txias yog PAG-80, tsis tshua muaj kub 200 degrees tempering, tom qab tempering, HRC62 los yog saum toj no yuav tsum tau, yog li cov txheej txheem kev kho cua sov tuaj yeem ua tau raws li qhov yuav tsum tau ua?

01. Cov kev xav tau hardness yog tsis tsim nyog. Tom qab quenching, nws tsuas yog hais txog 60HRC, thiab nws yog ib qho nyuaj rau ncav cuag 58HRC tom qab tempering ntawm 200 degrees.

02. Nws yog qhov tsis tsim nyog xav tau HRC62 lossis siab dua tom qab tempering hauv qhov xwm txheej no. Feem ntau, nws yuav tsum muaj ntau dua HRC55 tom qab tempering.

03. Cov kev xav tau hardness yog tsis tsim nyog. Feem ntau, qhov quenching hardness ntawm 40Cr yog HRC52-60, thiab cov nplaim hluav taws tuaj yeem ncav cuag HRC48-55.

04. Siv cov quenching siab, 160 tempering rau 2 teev, nws yog ua tau kiag li, peb li no, tsis muaj teeb meem dab tsi, peb qhov nruab nrab cua txias yog dej huv.

05. Siv cov quenching high-frequency, nws yog ib qho nyuaj los xyuas kom meej tias txhua rab koob kuaj yog siab tshaj 62HRC yam tsis muaj tempering tom qab quenching!

1. High-frequency quenching los ntawm ib txoj kev txhaj tshuaj, cov txheej txheem hardened yog ntiav (tej zaum tsawg tshaj li cov hauv paus hniav), thiab cov cua kub mem tes tuaj yeem siv los daws nws.

2. Nws yog ib qho nyuaj rau ua tiav lub hardness ntawm quenching raws cov hniav zawj saum HRC62 rau nruab nrab zaus. Feem ntau, qhov teeb meem tsis loj dua HRC55

3. Hardness yog qhov nyuaj rau ncav cuag, 200 degrees tsis tshaj 60HRC feem ntau.
