Austempering yog los txo cov deformation ntawm cov yeeb nkab steel thiab ib txoj kev zoo ntawm quenching tawg Jian, tab sis yuav ua li cas kom siv cov txheej txheem yuav tsum tau raws li tsim nyog seamless steel yeeb nkab khoom, qhov loj, hardness thiab toughness, deformation yuav tsum, thiab tej yam kev mob ua hauj lwm. Kev xaiv yuav yog Isotherml quenching teeb meem uas xav tau kev saib xyuas yog cov ntsiab lus hauv qab no:
[1] Xws li cov pa roj carbon steel thiab lwm yam qis hardenability ntawm steel austempering quenching hardening, yuav tsum tsim nyog kom lub quenching kub, H yog ua kom cov stability ntawm lub austenite kom tsis txhob thiab tiv thaiv qhov tshwm sim ntawm high-temperature non-shellfish nyob rau hauv ib tug. austempering quenching txheej txheem kev hloov pauv lub cev.

[2] Austempering txwv steel thiab yeeb nkab loj. Thaum lub sij hawm austempering quenching quenching, lub hauv paus ntsiab lus yog los xyuas kom meej tias qhov kev hloov tsis tshwm sim seamless steel siab kub hauv cov txheej txheem txias, thiab yog li qhov loj ntawm seamless steel yeeb nkab steel qib thiab muaj kev cuam tshuam ncaj qha rau qhov zoo ntawm austempering quenching quenching, dav dav. Cov kev cai rau cov pa roj carbon steel seamless yeeb nkab zoo thickness yuav tsum tsawg dua 5 hli, cov thickness zoo ntawm cov hlau yuav tsum tsawg dua 30 hli. Los ntawm qhov kev xav ntawm cov ntsiab lus carbon hauv 0.4% mus rau 0.6% ntawm cov pa roj carbon tsis haum rau austempering, siab dua 0.6% lossis ntau dua ntawm carbon steel rau austempering quenching.

[3] Kub thiab lub sij hawm yuav tsum tau ua raws li austempering hardening seamless steel yeeb nkab kev ua tau zoo, xa mus rau steel C-nqaj yog txiav txim siab, nyob rau hauv txoj cai, tag nrho cov austenite yog hloov mus rau hauv bainite, nyob rau hauv lub txias nruab nrab feem ntau nitrate da dej tov nyob rau hauv kev txiav txim. los xyuas kom meej qhov kub thiab txias, cov cuab yeej cua txias yuav tsum tau ntxiv rau hauv nruab nrab kom tsis txhob muaj qhov kub ntawm qhov nruab nrab cuam tshuam qhov zoo ntawm quenching. Thiab lwm yam ntxiv rau qhov ntev ntawm qhov kub thiab txias yuav tsum npaj qhov kev hloov pauv kawg seamless steel yeeb nkab raws li qhov ntsuas, kev ua haujlwm ntev yog txo, thiab yog li yuav tsum tau ua tiag tiag.

[4] Austempering hardening steel thiab qee qhov yuav tsis tempered. Tab sis rau ib co ^ lub cev hardening ntawm lub workpiece, lub sab hauv residual austenite yuav hloov nyob rau hauv lub tom ntej no cua txias txheej txheem yog martensite, yuav tsum tau tempered, lub hom phiaj yog tshem tawm brittleness thiab stability seamless steel kav, nco ntsoov lub tempering kub yuav tsum tau. hauv qab qhov kub thiab txias.
