Khoom Description
J Bolts, tsis yog- tus qauv fastener uas sib txuas ua haujlwm ntawm ob lub hauv paus ua ntej- txhim kho thiab hoisting kev twb kev txuas, tawg los ntawm daim ntawv thov kev txwv ntawm cov tsoos ncaj bolts nrog nws "J"- zoo li tus nuv tsim. Nws tau dhau los ua ib qho tseem ceeb hauv kev sib txuas, kho, ua ntej-embedding, hoisting thiab lwm yam xwm txheej, thiab tau siv dav hauv cov haujlwm tseem ceeb xws li kev tsim khoom, kev tsim vaj tsev, hluav taws xob, thiab kev thauj mus los.
Lub hauv paus tseem ceeb txiav txim siab cov khoom siv kho tshuab, kev tiv thaiv corrosion, thiab kev pabcuam lub neej ntawm J Bolts yog qhov kev xaiv ntawm cov khoom tsim. Peb siv siab - zoo nkauj nkauj xwb steel los xyuas kom meej kev ruaj ntseg ntawm kev ua tau zoo nyob rau hauv txhua batch ntawm cov khoom. Peb xaiv cov ntaub ntawv tsim nyog raws li qhov tseeb daim ntawv thov scenario. Cov khoom siv feem ntau muab faib ua peb pawg tseem ceeb: carbon steel, alloy steel, thiab stainless hlau. Lawv cov yam ntxwv ntawm kev ua haujlwm thiab kev siv yog raws li hauv qab no:
Q235 Tsawg- carbon steel:
Yield zog Ntau dua los yog sib npaug rau 235MPa, tensile zog Ntau dua los yog sib npaug rau 375MPa, zoo heev plasticity thiab toughness, haum rau lub teeb loads los yog dav siv;
01
45 # Nruab nrab- carbon steel:
Yield zog Ntau dua los yog sib npaug rau 355MPa, tensile zog Ntau tshaj los yog sib npaug rau 600MPa, superior hardness thiab lub zog, haum rau nruab nrab loads thiab nruab nrab lub zog daim ntaub ntawv, xws li cov khoom siv hauv paus kho, me me choj embedded qhov chaw, thiab cov khoom siv sib txuas;
02
40 Cr:
Lub zog tawm los Ntau dua lossis sib npaug ntawm 785MPa, lub zog tensile Ntau dua lossis sib npaug ntawm 980MPa, muaj ob qho tib si lub zog thiab tawv, haum rau hnyav -cov khoom siv kho, nruab nrab- qhov loj ntawm choj embedded qhov chaw, thiab engineering machinery kev sib txuas;
03
304 stainless hlau:
Yield zog Ntau dua los yog sib npaug ntawm 205MPa, tensile zog Ntau dua los yog sib npaug rau 515MPa, haum rau kev ua zaub mov, tshuaj, tshuaj, kho kom zoo nkauj sab hauv thiab sab nrauv, thiab lwm yam.;
04
316 stainless hlau:
Muaj zog corrosion kuj, precisely haum rau marine engineering, chaw nres nkoj terminals, ntug hiav txwv dej, thiab muaj zog acid ib puag ncig nyob rau hauv kev lag luam tshuaj.

J Bolts cov txheej txheem tsim khoom ncaj qha cuam tshuam cov khoom zoo thiab kev ua haujlwm. Cov txheej txheem ntau lawm suav nrog kev npaj cov khoom siv raw, sib txuas sib sau, xov ua, kev kho cua sov, kho qhov chaw, tshuaj xyuas, thiab ntim khoom. Cov kauj ruam tshwj xeeb yog raws li nram no:
Raw Khoom Npaj:High - cov ntaub ntawv raw zoo yog siv, thiab cov ntaub ntawv raug txiav raws li tus qauv tsim. Burrs raug tshem tawm ntawm lub ntsej muag kawg tom qab kev npaj los tiv thaiv kev cuam tshuam nrog kev ua haujlwm tom ntej thiab siv.
Hook Forming:Qhov no feem ntau yog khoov txias thiab kub dabtsi yog khoov. Txias dabtsi yog khoov yog ua nyob rau hauv chav tsev kub uas siv cov yeeb nkab dabtsi yog khoov tshuab los yog folding tshuab, uas ua rau high efficiency thiab zoo nto zoo. Kub dabtsi yog khoov yuav tsum tau cua sov lub puag ncig steel mus rau qhov ua kub thiab ces siv tshwj xeeb pwm rau nuv txoj kev. Qhov zoo ntawm kev khoov kub yog nws lub peev xwm los ua cov txheej txheem loj -inch, siab - curvature hooks yam tsis muaj kev pheej hmoo ntawm kev tawg.
Xov Xwm Txheej Txheem:Kev ua cov xov muaj xws li tig thiab yob txoj kev. Tig yuav txiav cov xov seem siv lub tshuab dhos, ua rau cov xov siab precision, haum rau cov khoom me me -batch thiab siab - cov khoom precision. Yob txoj kev muaj xws li txias dov lub threaded seem siv ib tug xov dov tshuab, muab siab ua efficiency thiab haum rau loj ntau lawm.
Kev kho cua sov:Cov txheej txheem tseem ceeb yog quenching ua raws li siab -kub tempering. quenching muaj cua sov lub ntsia liaj qhov rooj kom siab tshaj nws qhov kub thiab txias, tuav nws ntawm qhov kub thiab txias, thiab tom qab ntawd maj mam txias nws (roj los yog dej txias) kom tau txais cov qauv martensitic, txhim kho hardness thiab lub zog. High -kub tempering muaj cua sov lub quenched ntsia liaj qhov rooj rau 500-650 degree, tuav nws ntawm qhov kub thiab txias, thiab ces cua txias kom tshem tawm quenching kev nyuaj siab.
Kev kho deg:Cov txheej txheem kho saum npoo tsim nyog raug xaiv raws li qhov tseeb ntawm daim ntawv thov scenario. Cov txheej txheem no suav nrog electro-galvanizing thiab kub-dip galvanizing. Electro-galvanizing siv cov txheej txheem alkaline lossis acidic zinc plating, nrog zinc txheej thickness tswj ntawm 5-15μm. Passivation kev kho mob yog ua tom qab galvanizing los txhim kho corrosion kuj. Kub-dip galvanizing suav nrog immersing lub ntsia liaj qhov rooj hauv molten zinc, nrog zinc txheej thickness tswj ntawm 65-100μm. Kub-dip galvanizing tshem tawm zinc nodules thiab burrs.
