Lub cub tawg yog qhov cub tawg uas ua kom sov li ntawm cov cua sov thiab muab tso rau hauv qhov chaw ua haujlwm (thiab tom qab ntawd. ntawm lub cub hluav taws tuaj yeem hluav taws xob yog hluav taws xob thiab roj, thiab qhov ntsuas kub tau ntsuas nrog cov khoom siv hluav taws xob nrog kev tswj hwm thiab tswj tau los ntawm cov cuab yeej {}
Cov khoom siv quenching yog siv rau kev txiav txim siab ntawm txhuas cov raj thiab cov cua kub ua ntej quenching, thiab qhov kub tshaj plaws yuav tsum yog tsawg dua ± 2. 5 degree; Thaum quenching, ib lub sijhawm hloov tsis ntev los ntawm tsis pub dhau 15 feeb yog qhov yuav tsum tau ua.
Yav dhau los, txhuas extrusions raug kho nrog nitrate (kno3) da dej tau raug tshem tawm cov khoom siv tsis sib xws, cov chaw ua haujlwm ntsug yog qhov chaw sov tshaj plaws, Cov yam ntxwv:
(1) Ua ntej quenching, cov khoom seem tau tuaj yeem ua kom yooj yim tusyees thiab sai;
(2) Cov ntaub ntawv tuaj yeem muab tso rau hauv lub quenching tank nyob rau hauv lub sijhawm luv tshaj;
(3) Nws tuaj yeem zam dhau txoj kev khoov ntawm cov khoom lag luam thiab kev ua kom muaj zog los ntawm kev ua kom nws tus kheej thiab cua sov, uas yog qhov ua rau muaj cov duab ntawm cov khoom lag luam;
(4) Cov khoom siv cov khoom siv ntawm cov khoom seem tom qab quenching yog uniform .
Ib txoj kev sib cav sib ceg tsim los ntawm cov khoom lag luam uas tsis yog siv rau cov khoom siv sib txawv me me, kilowatts, thiab nrog ntxiv ntawm cov khoom siv ancillary, tag nrho cov hwj huam yog 424 kilowatts .
Lub quenching rauv yog nruab nrog qhov yuam cov cua kub cua sov .
Txoj kev ua kom tig rov qab los ntawm Soviet Union yog nruab nrog cua kub ua si thiab muaj peev xwm siv tau los ua cov roj av loj los ntawm 4 m txog 20 m nyob rau hauv ntev, thiab txawm tias ntev.
