Yuav ua li cas kom paub qhov txawv ntawm kub-dip galvanizing thiab txias-dip galvanizing rau nto kho ntawm malleable steel yeeb nkab fittings?

Qhov tseeb, qhov ntxhib thiab dub yog nyob rau hauv ob txoj kev naming. Qhov ntxeev ntawm qhov khoob yog cov khoom tiav. Cov xim dub yog qhov txawv ntawm qhov dawb (galvanized qhov chaw). Nws tsuas yog hais tias qhov saum npoo ntawm malleable steel yeeb nkab fittings tsis galvanized zoo li cov khoom dub, yog li nws yooj yim rau cov tib neeg ua yuam kev. Malleable steel yeeb nkab blanks xa mus rau cov khoom cam khwb cia uas tsis tau machined. …

Qhov tseeb, qhov ntxhib thiab dub yog nyob rau hauv ob txoj kev naming. Qhov ntxeev ntawm qhov khoob yog cov khoom tiav. Cov xim dub yog qhov txawv ntawm qhov dawb (galvanized qhov chaw). Nws tsuas yog hais tias qhov saum npoo ntawm malleable steel yeeb nkab fittings tsis galvanized zoo li cov khoom dub, yog li nws yooj yim rau cov tib neeg ua yuam kev. Malleable steel yeeb nkab blanks xa mus rau cov khoom cam khwb cia uas tsis tau machined. Ntawm lawv, machining kev suav nrog lub qhov ncauj tiaj tus, shaping, galvanizing, threading thiab hauv ob sab phlu yas, thiab lwm yam. Cov blanks ntawm malleable steel yeeb nkab fittings muab faib ua raw blanks thiab siav blanks. Ntawm lawv, cov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob.

Cov xim dub ntawm malleable steel yeeb nkab fittings xa mus rau qhov tiav malleable steel yeeb nkab fittings yam tsis muaj kev kho deg. Nws cov yam ntxwv yog tias nws tau ua tiav los ntawm threading thiab lwm yam machining, tab sis nws nto tsis tau galvanized thiab anti-xeb, yog li nws yog hu ua dub qhov chaw. Qhov opposite yog cov galvanized yeeb nkab fittings, hu ua dawb qhov chaw, kuj hu ua galvanized qhov chaw. Cov khoom dawb tau muab faib ua cov khoom dawb tiav thiab cov khoom dawb ntxhib. Dawb blanks yog cov yeeb nkab fittings uas tau galvanized tab sis tsis threaded. Raws li qhov sib txawv ntawm galvanizing, nws tau muab faib ua qhov kub-dip thiab txias-dip qhov chaw, nrog rau qhov hu ua ci qhov chaw (uas yog, qhov saum npoo yog dipped hauv cov hmoov xim nyiaj thiab tom qab ntawd qhuav hauv qhov cub).

Lub vuam kub ntawm malleable steel yeeb nkab fittings feem ntau cuam tshuam los ntawm high-frequency eddy tam sim no thermal zog, uas yog feem ntau cuam tshuam los ntawm tam sim no zaus. Lub eddy tam sim no thermal zog yog proportional rau lub square ntawm lub tam sim no excitation zaus; thiab tam sim no excitation zaus yog cuam tshuam los ntawm excitation voltage, tam sim no thiab capacitance. , Cov nyhuv ntawm inductance.

Lub excitation zaus yog inversely proportional rau lub square root ntawm lub capacitance thiab inductance nyob rau hauv excitation Circuit Court, los yog proportional rau lub square root ntawm voltage thiab tam sim no. Ntev npaum li lub capacitance, inductance lossis voltage thiab tam sim no nyob rau hauv Circuit Court raug hloov, qhov excitation zaus yuav raug hloov, thiaj li tswj tau qhov kub thiab txias. Lub hom phiaj. Rau cov pa roj carbon tsawg, qhov vuam kub yog tswj ntawm 1250 ~ 1460 degree, uas tuaj yeem ua tau raws li qhov yuav tsum tau nkag ntawm cov yeeb nkab phab ntsa thickness ntawm 3 ~ 5 hli. Tsis tas li ntawd, qhov vuam kub kuj tuaj yeem ua tiav los ntawm kev kho qhov vuam ceev.

Thaum cov khoom siv hluav taws xob tsis txaus, cov ntug ntawm cov rhuab vuam tsis tuaj yeem ncav cuag qhov kub thiab txias, thiab cov qauv hlau tseem nyob ruaj khov, ua kom tsis tiav fusion lossis tsis tiav kev nkag; Thaum lub tshav kub input tsis txaus, lub rhuab ntug ntawm lub weld tshaj qhov vuam kub, uas ua rau overburning los yog dripping ua rau lub weld tsim ib tug molten qhov.
