Rau cov haujlwm European, ua ntejS235JR (En Txuj)Raws li cov qauv German qub St 37-2 yog maj mam ua phased tawm.

Pom zooKev cuam tshuam kev ua yeeb yam, xa khoom mob (kub-rolled \/ normized)Yuav tsum muaj qhov yuav tsum tau ua (piv txwv li, tuab yog).

 

 

 

 

Cov Khoom Kho Vajtse Txhua Hnub

Cov Ntawv Thov: Bolts, neeg rau, Hlau phaj fabricated qhov chaw; dav siv rau tsis yog-tseem ceeb thauj-bearing Cheebtsam.

V. Zauv thiab Vuam Txiav Txim Siab

Kev Ua Haujlwm Thermal Ua Haujlwm

Tuaj yeem ncaj qha kub kub, txias-dov, lossis stamped; Cov muaj peev xwm txias heev deformation muaj peev xwm (piv txwv li, khoov, ncab).

Moderate machinability; Pom zoo kom siv cov hlau ceev (HSS) txiav cov cuab yeej nrog kua rau txias.

Vuam cov txheej txheem

Xaiv electrode: Txhawm rau ntawm phau ntawv arc vuam, e4303 (J422) cov hluav taws xob yog qhov tsim nyog, muab cov nqi qis thiab kev siv tsawg.

Tsis muaj preheating yuav tsum tau: Kev siv vuam ntawm chav sov yog ua rau thickness tsawg dua los yog sib npaug rau 30mm, nrog kev pheej hmoo ntawm kev tawg txias.

Cov ntawv tseem ceeb: Post-Weld Kev Kho Tshav Kub Kub tsis tsim nyog, tab sis swb swb yuav tsum raug ntxuav kom tiv thaiv kom xeb.

Nto Kho

Raws li-Hoobkas nto muaj kub-rolled zeb teev (ntxhib). Rau kev tiv thaiv corrosion, uaTxhaj Tshuaj Blasting (Sa2.5 Qib)Ua raws li los ntawm kev thov cov xim pov thawj xeb lossis galvanization (piv txwv li, kub-dip galvanizing).
