Cov txheej txheem tsim qauv sib piv: erw vs kauv kav

Lus Qhia: Txuas cov txheej txheem sib txawv rau cov khoom muaj nqi

Kev tsim qauv yog qhov tseem ceeb uas txiav txim siab qhov ua tau zoo, nqi, thiab cov ntawv teev cov xwm txheej ntawm cov kav hlau steel. Rau Huayang Steel Yeeb Nkab Co., Ltd., Lub Chaw Tsim Tshuaj Kws Tsim TshuajCov Hluav Taws Xob Hluav Taws Xob Welded Hlau Kav, Mastering qhov sib txawv ntawm ERW thiab muab kauv yeeb nkab tsim cov txheej txheem tsis yog qhov tseem ceeb los muab cov neeg siv khoom nrog cov cim kev cai.

Ua ntej, peb yuav tsum qhia meej lub tswvyim tseem ceeb ntawm ERW kav kom nteg lub hauv paus rau cov txheej txheem sib piv.Dab tsi yog erw yeeb nkab?

Cov Chaw Muaj Kev Ruaj Ntseg: Cov chaw nyob hauv Flux tuaj yeem nyob hauv Weld, ua rau muaj kev pheej hmoo ntau hauv cov pej xeem noo;

DiskS: Arc tshav kub yog qhov nyuaj rau kev tswj hwm, ua rau 5% -8% Weld Diskion tus nqi (vs. ≤0,5% rau huayang'sHFW Steel Kav).

Post - Kev Kho Vuam: Precision Soj Ntsuam VS Yooj Yim Xov

ERW cov yeeb nkab ncej - kev kho (Huayang txoj kev tswj nruj heev)

Huaayang siv ib qho "Tag nrho - txheej txheem tshuaj xyuas + txheej txheem kev kho mob" rau erw kav dej:

Weld trimming thiab shaping

Cov khoom siv hluav taws xob zoo tib yam: Ib lub trimmer zoo tib yam: cov neeg siv tshuab trimmer tshem tawm tshaj weld hlaws dai (siab ≤0.2 hli), kom qhov siab ≤0.2 hli), ua kom qhov siab ≤0,2 hli), kom qhov siab ≤0.2 hli), kom qhov siab ≤0.2, kom qhov siab ≤0.2, kom qhov siab ≤0.2, kom qhov siab ≤0.2, kom qhov siab ≤0.2, kom qhov siab ≤0,2 hli), kom qhov siab ≤0,2 hli), ua kom qhov siab ≤0.2, kom qhov siab ≤0.2, kom qhov siab ≤0.2, kom qhov siab ≤0.2, kom qhov siab ≤0,2 hli), kom qhov siab ≤0,2 hli), kom qhov siab ≤0.2 hli

HFW Steel Kav: Ib qho kev sib tsoo tshuab sib tsoo tshuab polishes weld yuav yaug nrog cov yeeb nkab lub cev (deviation urn0.1mm), txo cov dej ntws tawm hauv cov dej thauj.

Kev Soj Ntsuam Zoo

Peb qhov kev soj ntsuam tseem ceeb kom zoo:

Ultrasonic qhov khuam kom pom kom tau txais: Scans lub weld 360 ° los tshawb nrhiav sab hauv qhov tsis xws luag (rhiab ≥0.5mm);

Hydrostatic siab kuaj: kev ntsuam xyuas ntawm 1.2-1.5 zaug lub siab ntsuas (piv txwv li 12mpa rauHFW Steel Kav) Li 10 feeb, tsis muaj kev xau tso cai;

Cov Cuab Yeej Cuab Yeej Cuab Yeej Cuab Tam: Kuaj cov tenso, cuam tshuam, thiab dabtsi yog khoov xeem (Huayang'sHFW Steel KavMuaj kev cuam tshuam kov yeej ≥60j / cm² ntawm -40 degree).

Muab kauv yeeb nkab ncej - kev kho

Muab kauv yeeb nkab ncej - Kev Kho Mob yog qhov yooj yim dua, tsom mus rau qhov yooj yim kho yam:

Flux Ntxuav: siv txhuam cov ntsej muag lossis dav hlau kom tshem tawm cov ntsej muag saum npoo, tab sis sab hauv qhov chaw tsis yooj yim los tshem tawm;

Kev Kho Mob: X {- pay Qhov kev pom tsis meej (piv txwv li cov kev sib cais ntawm phau ntawv vuam (tsawg nyiaj thiab tsis zoo sib xws);

Tsis muaj qhov ntsuas siab: Vim tias txoj kab uas hla loj thiab tus nqi loj, cov kav dej siab tshaj plaws hla kev ntsuas hydrostatic siab, ua kom muaj kev phom sij ntau.
