Qhov zoo ntawm ntsev da dej quenching:

Qhov zoo ntawm ntsev da dej quenching:

1. Lub sij hawm quenching cua sov yog luv, cov hmoov nplej siv lead ua yuav tsis coarsened, thiab lub toughness yog muaj zog, uas yog zoo rau strain.

2. Qhov kub ntawm lub cub tawg tau muab faib ua kom zoo thiab lub zog ua kom tsawg dua.

3, qhov kub ntawm qhov chaw txias txias sai, qhov kub tsis tshua muaj qhov txias txias, qhov quenching yog ib qho yooj yim, thiab lub zog txo.

4. Nws tuaj yeem tswj tau ntau yam kev kho cua sov (sib ntus quenching, austempering, kev kho cua sov ib nrab, cua sov lub sij hawm luv luv, cua txias, kev hloov kub ntxhov, thiab lwm yam).

5. Tsawg oxidative decarburization.

6. Kev hloov kho ntawm kev kho cua sov thiab lub sijhawm tuaj yeem ua tiav hauv lub sijhawm luv luv, thiab tuaj yeem txhawb nqa ntau yam thiab cov khoom me me.

7. Cov nqi khoom siv kuj pheej yig.

Lub qhov cub ntsev da dej tau muab faib ua hom cua sov sab nraud thiab hom cua sov sab hauv

Tam sim no quenching nyob rau hauv lub qhov cub kub ntsev da dej: siab thermal efficiency, tsis muaj thermal inertia, ceev ceev cua sov, tsis zoo cua sov, yooj yim ua hauj lwm, muaj peev xwm tiv thaiv oxidative decarburization, thiab lub cub tawg kub yuav nce mus txog 1300 degrees. Nws yog tsim rau steel quenching thiab tempering cua sov thiab kua tshuaj thaum tshav kub kub kev kho mob, tshwj xeeb tshaj yog haum rau high kub quenching cua sov. Piston pins (xws li tsheb) txuas lub piston thiab tus pas nrig txuas. Thaum nyob rau hauv cov lus tsa suab, nws yog sib npaug rau ob-taw tes beam, bearing asymmetrical alternating load thiab ib tug tej yam cuam tshuam load, thiab nws nto yuav tsum txaus los ua hauj lwm nyob rau hauv kev sib txhuam rau ib tug ntev lub sij hawm. Lub zog, toughness, abrasion kuj thiab qaug zog txwv. Feem ntau, piston pins ua nyob rau hauv daim ntawv ntawm bar Tshuag, kub dov raj, los yog txias drawn tube yog machined, carburized, quenched, tempered, thiab tiav rau hauv cov khoom tiav. Yog li ntsev da dej quenching tsis tuaj yeem siv qhov chaw ntawm carburizing quenching, tab sis ntsev da dej rauv tuaj yeem ua tau carburized. Tom qab ntsev da dej quenching, tempering yuav tsum tau ua!
