Peb muaj ntau yam kub dov cov qauv carbon profiles, nrog rau lub kaum sab xis steel, I-zoo li tus steel, C-zoo li tus steel, thiab H-zoo li tus steel, muaj nyob rau hauv hwm ASTM A36 thiab Q345b qib, engineered kom tau raws li nruj thoob ntiaj teb thiab cheeb tsam cov qauv. ASTM A36 ua raws li Asmeskas tus qauv ASTM, thaum Q345b ua raws li Tuam Tshoj tus GB / T 1591 tus qauv rau qis- alloy siab- lub zog steel. Crafted los ntawm siab- zoo carbon thiab tsawg- alloy steel nrog precisely tswj tshuaj muaj pes tsawg leeg -optimized carbon, manganese, thiab kab kawm theem-cov qauv profiles muab tshwj xeeb mechanical zog, kev ruaj ntseg, thiab durability. Tsim los rau ntau hom kev lag luam, kev lag luam, thiab kev tsim kho vaj tse, lawv ua haujlwm ua haujlwm tseem ceeb -cov kabmob thiab cov khoom sib txuas, muab ntau yam thiab kev ntseeg siab ntawm cov txheej txheem nyuaj.
Cov qib ASTM A36 thiab Q345b nthuav tawm cov khoom siv kho tshuab kom haum rau siab -xav tau cov qauv tsim. ASTM A36, uas yog siv dav hauv cov qauv hlau, muaj qhov tsawg kawg nkaus lub zog ntawm 250 MPa (36,000 psi) thiab lub zog tensile ntau ntawm 400-550 MPa (58,000-80,000 psi), nrog rau qhov zoo tshaj plaws ductility 0.2% thiab mination. Q345b, qis- alloy siab- qib siab zog, xa cov khoom txhim khu kev qha- cov kabmob muaj peev xwm nrog qhov tsawg kawg nkaus lub zog ntawm 345 MPa thiab tensile lub zog ntawm 470-630 MPa, nrog rau kev ua kom zoo dua qub -tshwj xeeb tshaj plaws 2 daim ntawv thov hnyav. Ob qib yog sib xws nrog txhua tus qauv vuam txoj kev (shielded hlau arc vuam, roj hlau arc vuam, flux-cored arc vuam), ua kom yooj yim seamless on-site fabrication thiab kev koom ua ke rau ntau yam qauv sib dhos.
Tag nrho cov txheej txheem cov txheej txheem yog tsim los ntawm cov txheej txheem kub dov txheej txheem (ua ntawm qhov kub siab tshaj 900 degree, tshaj cov hlau recrystallization point), uas refines cov qauv nplej los txhim kho toughness, cuam tshuam, thiab tag nrho cov qauv stability. Cov khoom lag luam suav nrog plaub yam tseem ceeb ntawm cov khoom siv tshwj xeeb rau kev ua haujlwm tshwj xeeb: Lub kaum sab xis steel (sib npaug / tsis sib npaug L- zoo li, piv txwv li, 40 × 40 × 3, 100 × 75 × 6 mm) rau bracing, framing, thiab kev txhawb nqa; Kuv-zoo li tus steel (Kuv-beam, nrog ntau yam flange widths thiab web thicknesses) ntev -span load- bearing; C-zoo li tus steel (channel steel, zoo tagnrho rau lub teeb rau nruab nrab-lub luag haujlwm framing thiab purlins); thiab H-zoo li steel (H{18}}beam, muab superior load{19}}bearing peev xwm rau hnyav{20}}cov dej num xws li siab- nce thiab txuas hniav). Cov txheej txheem kub dov ua kom muaj qhov tseeb ntawm qhov tseeb, cov tuab tuab, thiab kev ua siab ntev ntev thoob plaws txhua qhov profile, thaum lub ntuj nto tiav ua kom zoo heev rau kev tiv thaiv kev kho mob (galvanization, epoxy txheej) los txhim kho corrosion.
Ua tsaug rau lawv cov ntau hom profile thiab qib kev xaiv lub zog, cov kub dov ASTM A36 thiab Q345b cov qauv carbon profiles tau siv dav hauv ntau yam kev siv. Lawv yog cov khoom tseem ceeb hauv kev lag luam siab - nce siab, kev cob qhia kev lag luam, thaj chaw nyob, txuas hniav, viaducts, thiab cov phiaj xwm kev tsim kho. Cov kev siv tshwj xeeb muaj xws li lub tsev thav duab, hauv pem teb beams, ru tsev trusses, phab ntsa bracing, choj girders, thiab hnyav machinery puag. Cov txheej txheem kev ruaj ntseg zoo yog siv thoob plaws hauv kev tsim khoom, suav nrog kev tshuaj xyuas tshuaj lom neeg los ntawm kev kho qhov muag emission spectrometry, kev txheeb xyuas cov cuab yeej cuab tam (tensile, yield, elongation, thiab kev ntsuam xyuas cuam tshuam), kev tshuaj xyuas qhov ntev nrog cov cuab yeej ntsuas ntsuas qhov tseeb, thiab kev kuaj pom qhov tsis xws luag. Cov kev ntsuas nruj no ua kom muaj kev ua raws li ASTM thiab GB / T cov qauv, lav kev ua haujlwm zoo ib yam thoob plaws txhua pawg. Rau cov kws tsim khoom, cov neeg cog lus, thiab cov neeg tsim khoom nrhiav kev nthuav dav, siab -kev ua tau zoo ntawm cov qauv carbon profiles rau txoj haujlwm tsim kho, peb cov khoom lag luam muaj ntau yam tsis sib xws, kev ntseeg tau, thiab tus nqi tsim nyog.
