35CRMo Precision Bright Tube
Nws yog siv los tsim cov khoom tseem ceeb hauv ntau lub tshuab uas dais cuam tshuam, khoov thiab torsion, thiab siab loads, xws li dov zeb herringbone zog, crankshafts, rauj rods, txuas rods, fasteners, chav turbine cav lub ntsiab shafts, axles, cav kis tau tus mob qhov chaw , loj lub cev muaj zog shafts, perforators nyob rau hauv roj av machinery, bolts rau boilers nrog kev khiav hauj lwm kub hauv qab no 400 degrees Celsius, txiv ntseej hauv qab 510 degrees Celsius, seamless tuab-walled kav rau kev kub siab nyob rau hauv tshuaj machinery (kub 450 txog 500 degrees Celsius, tsis muaj corrosive media), thiab lwm yam .; Nws kuj tseem siv tau los hloov 40CrNi los tsim cov khoom siv siab load, lub cav turbine cav rotors, loj seem zog, txhawb shafts (inch tsawg dua 500MM), thiab lwm yam.; txheej txheem cov khoom siv, cov kav dej, cov khoom siv vuam, thiab lwm yam.
Siv raws li cov qauv tseem ceeb uas ua haujlwm nyob rau hauv siab loads, xws li kis tau tus mob qhov chaw ntawm lub tsheb thiab cav; rotors, main shafts, heavy-duty tsav shafts, loj-section qhov chaw ntawm turbo-generators

Raws li cov pa roj carbon pom zoo los ntawm International Institute of Welding (IIW) (1) thaum Ceq 0.60%, 35CrMo precision ci raj muaj lub siab nyiam ua kom tawv thiab tsis zoo weldability. Nws yog qib nyuaj-rau-weld steel thiab yuav tsum tau welded nrog siab dua Preheating kub thiab nruj txheej txheem ntsuas, xaiv cov khoom siv vuam tsim nyog. Tom qab kev suav, cov pa roj carbon sib npaug ntawm 35CrMo precision ci raj Ceq = 0.72%. Nws tuaj yeem pom tau tias cov khoom siv weldability yog qhov tsis zoo, thiab nws muaj qhov ua kom tawv dua thaum lub sijhawm vuam, thiab qhov kub thiab txias tawg nyiam ntawm thaj chaw muaj kev kub ntxhov yuav ntau dua, tshwj xeeb tshaj yog thaum vuam hauv lub xeev quenched thiab tempered. , qhov txias cracking nyiam ntawm tshav kub-cuam tshuam cheeb tsam yuav yog Qhov kev ua tau zoo heev, yog li ntawm kev xaiv cov khoom siv vuam tsim nyog thiab cov txheej txheem vuam tsim nyog, ntau dua. pre-heating kub ua ntej vuam, nruj txheej txheem ntsuas thiab tswj qhov tsim nyog interlayer kub tuaj yeem ua tiav kom tiav cov khoom vuam. Lub hom phiaj.
