Q: Thaum twg yog yuav tsum muaj rau vuam S235jr H-Beams?
A:Preheating tsis tseem ceeb rau cov tuab tuab hauv qab 30 hli vim tias zoo heev weldability. Thicker cov ntu lossis cov pob qij txha ua haujlwm xav tau {{2} ° C preheat kom tiv thaiv hydrogen cracking. Interpass qhov kub siab yuav tsum tsis pub dhau 250 ° C kom tsis txhob muaj kev puas tsuaj microstructural.
Q: Vim li cas siv waterjet txiav rau s235jr hloov kho?
A:Waterjet txiav tshem tawm cov chaw kub-cuam tshuam rau cov aav, khaws cov khoom siv ze ze txiav cov npoo. Nws ua tiav sub-millimeter tseeb rau cov ntsiab lus tsis zoo. Cov txheej txheem ua rau xoom distortion, ua rau nws zoo tagnrho rau post-galvanized nqaj.
Q: Tus qauv lis lag luam yog tswj thaum lub sijhawm dov?
A:Kawg rolling tshwm sim saum 850 ° C txhawm rau txhawm rau txhim kho austenite nplej. Cov nqe lus tseem ceeb tshaj plaws thov tshaj 20% txo qis qis dua 950 ° C txhawm rau txhawm rau kev loj hlob. Ntxiab ntsab kaw lub xauv zoo ferrite-hlaws microstructures, kom muaj zog.
Q: Vim li cas nrawm cua txias tom qab kub dov?
A:CEEV CEEV CUA High-zog microstructures, tsis tu ncua dhau los cov kev xav tau. Qeeb Cua Txias txaus ntshai heev ferrite, txo lub zog los ntawm 10-15%. Uniform txias tiv thaiv cov kev ntxhov siab thiab cov nqaj ntseej.
Q: Yuav ua li cas parallel-flange kab teeb tsa optimized rau dabtsi yog khoov?
A:Txo flange-rau-web tuab piv tau cov buckling thaum tab tom khoov. Qhov tsawg kawg nkaus khoov Radii tau teeb tsa ntawm tsib zaug flange dav. Induction cua sov pab kom nruj-vojvoog curves rau cov ntawv thov arches rau cov ntawv thov.
