Hlau phom qhia txog hlau:
Kev sib tsoo hlau yeeb nkab yog tsuas yog siv rau cov hluav taws xob cog, lub zog hluav taws xob, kev kub siab boiler yeeb nkab, kub siab thiab kev kub siab kub superheater thiab reheater thiab thiaj li rau thiab khoom siv, nws tau ua los ntawm cov qib siab zoo steel, hlau alloy thiab stainless hlau khoom, qhov kub (dlhos, nthuav dav) los sis txias dua (thaij) thiab lwm yam.
Alloy Steel Kav Zoo:
Alloy steel yeeb nkab ua lus Askiv (hlau hlau yeeb nkab) qhov loj tshaj plaws zoo dua yuav tsum siv 100%, nyob rau hauv txoj kab nrog kev tiv thaiv, kev txuag hluav taws xob, kev pab txuag lub teb chaws uas zoo, lub teb chaws txoj cai los txhawb kom muaj kev nthuav dav ntawm kev kub siab hlau alle tube. Tam sim no, Tuam Tshoj txoj kev yeeb nkab txhuam cov nyiaj tsuas yog siv ib nrab ntawm cov khoom siv hlau, thiab kev siv cov hlau tho tawm kom muab qhov chaw dav dav rau txoj kev lag luam. Raws li cov kev tshawb fawb ntawm cov kws pab tswv yim ntawm lub koom haum tshwj xeeb hlau nyob rau hauv Suav Tuam Tshoj alloy tube, high-pressure alloy khoom ntev txog li 10-12% nruab nrab txhua xyoo kev loj hlob nyob rau hauv kev thov rau yav tom ntej. Cov yeeb nkab hlau yog cov yeeb nkab raws li cov khoom siv (lossis khoom) los txhais cov ntsiab lus ua los ntawm cov yeeb nkab yeeb nkab thiab seamless steel yeeb nkab; yog raws li cov txheej txheem (seamed seamless) txhais, sib txawv ntawm seamless yeeb nkab pob qij txha, nrog rau cov yeeb nkab thiab cov raj roj hmab.
Cov hlau hauv cov khoom siv:
16-50Mn, 27SiMn, 40Cr, 12-42CrMo 16Mn12Cr1MoV, T91 27SiMn 30CrMo 15CrMo Cr9Mo 10CrMo910 15Mo3 15CrMoV 35CrMoV 20G 45CrMo, 15CrMoG, 12CrMoV, 45Cr, 50Cr, 45CrNiMo thiab lwm yam.
Quenching thiab tempering txheej txheem ntawm hlau alloy steel:
Lub tswv yim nthuav tawm txoj kev kub ntxhov ntawm cov hlau ciav hlau, hlau phom, ntxhua thiab ntxhua los ntawm nws lub zog muaj zog, siab tawv, ua kom tsis muaj zog, muaj zog, kub siab, me me deformation, decarburization, uas muaj li hauv qab cov kauj ruam nram no: 1) 20-25 C / min ceev ceev mus rau 870-880 DEG C, kub 35-40 feeb, thiab txias dua mus rau 500 DEG C; 2) quenching: 5-10 C / min cua kub ceev rau 930-935 deg.c, cua sov 50-60 feeb, thiab tom qab ntawd, tom qab 190-200 C / s ceev ceev txias rau 320-325 CEG, txias rau 30 -40 degrees C; 3): npau ntawm 5-10 Deg. C / min cua kub cua kom 500-510 deg.c, tshav kub 230-240 feeb, thiab tom qab ntawd txias rau chav sov. Kev quenched thiab tempered alloy steel tube muaj qhov zoo ntawm lub zog, siab tawv, zoo coj los ua haujlwm, muaj zog loj, muaj zog loj, me me deformation thiab me me decarburization. Tsab ntawv tsim muaj rau kev siv quenching thiab tempering ntawm hlau alloy hlau rau hydraulic lub tog raj kheej hydraulic.
