Dab tsi yog cov ntsiab lus tseem ceeb ntawm Q235B galvanized ncaj seam hlau?
Lub ntsiab alloying ntsiab ntawmQ235Byog cov pa roj carbon, silicon, thiab manganese, uas nws cov ntsiab lus yog tswj nyob rau hauv ib tug tshwj xeeb ntau yam kom ua tau raws li cov neeg kho tshuab zog uas yuav tsum tau rau qhov no feem ntau siv carbon structural steel. Nws kuj tseem muaj me me ntawm phosphorus thiab sulfur, cov ntsiab lus ntawm cov khoom txwv kom ntseeg tau zoo weldability thiab kev ua tau zoo.
Dhau li ntawm kev tiv thaiv corrosion, lwm yam kev tiv thaiv tseem ceeb dab tsi ua cov txheej txheem galvanized muab rau cov yeeb nkab steel?
Ntxiv nrog rau corrosion kuj, lubgalvanized txheejkuj tseem muab kev tiv thaiv cathodic, kev tiv thaiv txhua yam, thiab tus kheej - kho cov khoom, tiv thaiv xeb los ntawm kev sib kis txawm tias cov txheej txheej yog khawb.
Dab tsi yog cov txheej txheem tseem ceeb rau Q235B galvanized ncaj seam steel kav?
Lub ntsiab txheej txheem rauQ235B galvanized ncaj seam kavsuav nrog: nthuav tawm cov hlau sawb thiab ntug- kho nws, tom qab ntawd ua rau hauv cov yeeb nkab, thiab thaum kawg siv cov txheej txheem vuam ntau zaus los fuse lub vuam seam.
Q235B galvanized ncaj seam yeeb nkab feem ntau yog cua sov li cas- kho kom txhim kho weldability?
Q235B galvanized ncaj seam kavfeem ntau tau txais kev kho cua sov thaum lub sijhawm tsim khoom, ua haujlwm nruab nrab -ntau zaus induction online annealing txheej txheem los tshem tawm cov kev ntxhov siab nyob hauv qhov vuam. Qhov no txhim kho weldability los ntawm kev ua kom thaj tsam weld zoo ib yam thiab tiv thaiv cov teeb meem tom qab los ntawm kev ntxhov siab.
Qhov kev ntsuam xyuas siab npaum li cas yog qhov yuav tsum tau ua rau cov kav hlau siv los thauj cov kua dej?
Thawj qhov kev ntsuas siab rau cov kav dej steel yog qhov kev sim hydrostatic, uas suav nrog kev ntim cov yeeb nkab nrog cov kua thiab nias nws mus rau qhov kev ntsuas siab (feem ntau yog 1.25 txog 1.5 npaug ntawm qhov siab tshaj plaws kev khiav hauj lwm siab) los xyuas cov dej xau thiab kev ua haujlwm zoo.
