Dab tsi yog cov yam ntxwv tseem ceeb ntawm lub kaum sab xis steel?
Lub kaum sab xis steel, feem ntau hu ua lub kaum sab xis hlau, yog ib txoj hlua ntev ntawm cov hlau nrog ob sab perpendicular rau ib leeg thiab tsim lub kaum sab xis. Muaj ob hom kaum sab xis: lub kaum sab xis steel thiab lub kaum sab tsis sib npaug. Ob sab ntawm lub kaum sab xis steel muaj qhov dav sib npaug. Lub kaum sab xis steel tuaj yeem siv los tsim ntau yam khoom siv thauj khoom raws li cov txheej txheem sib txawv, thiab tuaj yeem siv los ua cov khoom sib txuas ntawm cov khoom.
Lub kaum sab xis steel belongs rau carbon structural steel siv rau kev tsim kho, uas yog ib qho yooj yim seem hlau. Nws yog tsuas yog siv rau hlau Cheebtsam thiab lub moj khaum ntawm lub Hoobkas tsev. Zoo weldability, yas deformation kev ua tau zoo, thiab qee yam khoom siv zog yuav tsum tau siv thaum siv. Cov khoom siv raw rau kev tsim lub kaum sab xis steel billets yog qis-carbon square steel billets, thiab lub kaum sab xis tiav yog xa mus rau hauv kub dov, normalized lossis kub dov lub xeev.
Lub kaum sab xis steel yog dav siv nyob rau hauv ntau lub tsev thiab engineering lug, xws li kab teeb, txuas hniav, kis tau tus yees, nqa thiab tsheb thauj mus los machinery, ships, industrial furnaces, tshuaj tiv thaiv yees, cable trench txhawb nqa, hwj chim piping, busbar txhawb installation, thawv racks, thiab warehouse txee.
Txoj kev soj ntsuam rau lub kaum sab xis steel
Cov tsos mob zoo: Qhov zoo ntawm lub kaum sab xis steel yog teev nyob rau hauv tus qauv thiab feem ntau yuav tsum tsis txhob muaj teeb meem tsis xws luag thaum siv, xws li txheej txheej, caws pliav, kab nrib pleb, thiab lwm yam. Qhov tso cai ntau yam ntawm geometric sib txawv ntawm lub kaum sab xis steel kuj tau teev nyob rau hauv tus qauv (GB9787-88/GB9788-88), uas feem ntau suav nrog khoov degree, ntug dav, ntug thickness, sab saum toj kaum, theoretical hnyav, thiab lwm yam, thiab nws tau teev tseg tias lub kaum sab xis steel yuav tsis muaj qhov tseem ceeb. torsion.
Kev tshuaj ntsuam xyuas kev ua tau zoo: ① Tensile test method. Cov txheej txheem kev tshuaj xyuas feem ntau suav nrog GB / T228-87, JISZ2201, JISZ2241, ASTMA370, FOCT1497, BS18, DIN50145, thiab lwm yam Bending test method. Cov txheej txheem kev tshuaj xyuas feem ntau suav nrog GB / T232-88, JISZ2204, JISZ2248, ASTME290 ГОСТ 14019, DIN50111, thiab lwm yam. Cov khoom tshuaj ntsuam xyuas kev ua haujlwm ntawm lub kaum sab xis steel feem ntau suav nrog kev ntsuas tensile thiab dabtsi yog khoov. Cov ntsuas muaj xws li qhov taw tes tawm, lub zog tensile, elongation, thiab tsim nyog khoov.
GNEE Group tau txais cov neeg tuaj xyuas
GNI Group tau txais cov neeg siv khoom thoob plaws ntiaj teb txhua xyoo los sib tham txog kev koom tes nrog lub tuam txhab. Lub tuam txhab ua raws li lub hauv paus ntsiab lus ntawm "kev ua tau zoo ua ntej, kev ncaj ncees ua ntej, thiab cov neeg siv khoom ua ntej" thiab tau tsim kom muaj kev sib koom tes ntev-yeej nrog cov neeg siv khoom los ntawm thoob plaws lub ntiaj teb. Nyob rau tib lub sijhawm, peb zoo siab tos txais cov neeg siv khoom tshiab thiab qub los ntawm txhua qhov chaw ntawm lub neej los tiv tauj peb, tsim kev sib raug zoo rau kev lag luam yav tom ntej, thiab txhim kho ua ke!
