Cov cua sov ceev thiab quenching cuam tshuam nrog preheating lub cub tawg kom sov rau qhov kub siab dua li qhov uas yuav tsum tau quenching kub. Lub workpiece yog tom qab ntawd thauj mus rau hauv qhov cub thiab cua sov (lossis hluav taws xob) muab tau tua. Thaum lub cua sov sov kom sov rau lub quenching kub, tshav kub (lossis hluav taws xob) tau rov qab thiab tswj tau. Tom qab lub workpiece yog tag nrho rhuab, nws tau muab tshem tawm thiab quenched.
Thaum lub sijhawm ua cua sov thiab quenching, lub cua sov sov yog kwv yees li ntawm qhov kev tswj hwm cua sov, yog li tiv thaiv kev ua haujlwm kub.
Kev xyaum ntau lawm tau pom tias tsuas yog tsa lub quenching kub los ntawm ob peb kaum ntawm cov ntsuas kub tuaj yeem ua rau lub caij sov. Vim tias cov cua kub ceev ceev txhawb nqa ntau nucleation thiab lub sijhawm luv luv luv tiv thaiv qoob loo kev loj hlob, ib tug finer grain loj tau tiav.
The rapid heating and quenching method is suitable for low- and medium-carbon non-alloy steels and low-alloy steels. Piv txwv li, Q345 (yav tas los tsim 16MN) Steel Sav HoTiliale cua sov thiab quenching nyob rau hauv 10% Nacl ntsev, thiab tempering ntawm 160℃rau 90 feeb). Qhov kev kov yeej ntawm lub sijhawm ntev ntev thiab cov haujlwm ua haujlwm tsis zoo cuam tshuam nrog cov dej ua ntej (cua sov hauv 10% Nacl ntsev, thiab tempering ntawm 160℃rau 90 feeb). Lub hardness yog nce los ntawm 42 txog 44 hrc nrog cov txheej txheem qub rau 42 txog 48 teev nrog cov txheej txheem tshiab. Ib txhij, Lath Martite nplej yog kho kom zoo, cov khoom tawv tawv qhov tob tob, thiab tag nrho cov khoom siv neeg siv hluav taws xob tag nrho yog txhim kho.
