Lub kaum sab xis steel tuaj yeem tsim ntau yam kev ntxhov siab raws li kev xav tau ntawm cov qauv sib txawv, thiab tuaj yeem siv los ua cov khoom sib txuas ntawm cov khoom. Nws yog dav siv nyob rau hauv ntau lub tsev thiab engineering cov qauv, xws li lub tsev kab teeb, txuas hniav, kis tau tus yees, hoisting thiab tsheb thauj mus los machinery, ships, industrial furnaces, tshuaj tiv thaiv yees, thawv racks, cable trench txhawb, hwj chim piping, tsheb thauj mus los txhawb installation, warehouse txee, etc.

Lub kaum sab xis belongs rau carbon structural steel rau kev tsim kho. Nws yog ib ntu steel nrog ntu yooj yim. Nws yog tsuas yog siv rau hlau Cheebtsam thiab cog ncej. Hauv kev siv, nws yuav tsum muaj qhov zoo weldability, yas deformation kev ua tau zoo thiab qee lub zog txhua yam. Cov khoom siv raw khoom rau lub kaum sab xis steel ntau lawm yog qis-carbon square billet, thiab lub kaum ntse ntse tiav yog xa hauv kub dov txoj kev, normalizing lossis kub dov lub xeev.

Nws feem ntau muab faib ua lub kaum sab xis steel thiab lub kaum sab tsis sib npaug. Lub kaum sab xis hlau tsis sib xws tuaj yeem muab faib ua ntug sib npaug sib npaug sib npaug thiab qhov tsis sib xws ntug tsis sib xws. Thiab perforated lub kaum sab xis steel. Peb kuj tsim H-section steel.

Lub specification ntawm lub kaum sab xis steel yog qhia los ntawm qhov ntev ntawm sab ntev thiab sab thickness. Tam sim no, qhov tshwj xeeb ntawm lub kaum sab xis steel yog 2-20, nrog rau tus lej ntawm centimeters ntawm sab ntev raws li tus lej. Tib lub kaum sab xis steel feem ntau muaj 2-7 txawv sab thicknesses. Qhov loj thiab tuab ntawm ob sab ntawm lub kaum sab xis ntawm cov hlau tuaj txawv teb chaws yuav tsum tau qhia, thiab cov qauv tsim nyog yuav tsum tau qhia. Feem ntau, lub kaum sab xis loj yog siv thaum lub sab ntev yog ntau tshaj 12.5cm, nruab nrab lub kaum sab xis steel yog siv thaum lub sab ntev yog nyob nruab nrab ntawm 12.5cm thiab 5cm, thiab lub kaum sab xis me me steel yog siv thaum sab ntev yog tsawg dua 5cm.

Qhov kev txiav txim ntawm ntshuam thiab xa tawm lub kaum sab xis steel feem ntau yog raws li cov lus qhia tshwj xeeb uas yuav tsum tau siv hauv kev siv, thiab nws cov qib steel yog cov qib carbon steel. Nws kuj yog lub kaum sab xis steel. Ntxiv nrog rau tus lej specification, tsis muaj qhov tshwj xeeb muaj pes tsawg leeg thiab kev ua tau zoo series. Kev xa khoom ntev ntawm lub kaum sab xis steel muab faib ua qhov ntev thiab ob qhov ntev. Qhov kev xaiv ntev ntev ntawm cov hlau hauv tsev yog 3-9m, 4-12m, 4-19m thiab 6-19m raws li tus lej specification. Qhov ntev xaiv ntau yam ntawm lub kaum sab xis steel ua nyob rau hauv Nyiv yog 6-15m.

Ntu qhov siab ntawm lub kaum sab xis hlau tsis sib npaug yog xam raws li qhov ntev thiab qhov dav ntawm lub kaum sab xis tsis sib npaug. Nws yog hais txog steel nrog angular seem thiab tsis sib npaug ntev ntawm ob sab. Nws yog ib qho ntawm lub kaum sab xis steel. Nws sab ntev yog 25mm × 16mm ~ 200mm × l25mm. Nws yog dov los ntawm kub dov zeb.

Qhov tshwj xeeb ntawm cov hlau tsis sib xws yog: ∟ 50 * 32 - ∟ 200 * 125, thiab thickness yog 4-18 hli.

Lub kaum sab xis hlau tsis sib xws yog siv dav hauv ntau cov qauv hlau, txuas hniav, tshuab tsim khoom thiab nkoj tsim, ntau lub tsev tsim thiab engineering, xws li cov kab teeb hauv tsev, txuas hniav, xa cov yees, hoisting thiab tsheb thauj mus los machinery, ships, industrial furnaces, tshuaj tiv thaiv yees, thawv racks thiab warehouses.

Ntshuam thiab export

Tuam Tshoj ntshuam thiab xa tawm lub kaum sab xis steel hauv qee cov khoom siv, feem ntau yog los ntawm Nyiv thiab Western Europe. Exports feem ntau yog xa mus rau Hong Kong thiab Macao, Southeast Asia, Latin America thiab Arab lub teb chaws. Export ntau lawm tuam txhab uas muag yog mas steel mills (rolling mills) nyob rau hauv Liaoning, Hebei, Beijing, Shanghai, Tianjin thiab lwm lub xeev thiab lub zos. Peb yog cov nroj tsuag steel hauv Tianjin.

Lub kaum sab xis ntawm cov hlau txawv teb yog feem ntau loj thiab me me lub kaum sab xis steel thiab lub kaum sab xis steel nrog cov duab tshwj xeeb, thiab cov khoom xa tawm feem ntau yog nruab nrab lub kaum sab xis steel, xws li No. 6, No. 7, thiab lwm yam.

Cov tsos zoo

Qhov zoo ntawm lub kaum sab xis steel yog teev nyob rau hauv tus qauv. Peb lub Hoobkas nruj me ntsis kom tsis txhob muaj kev puas tsuaj rau kev siv, xws li delamination, scab, tawg, 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, feem ntau suav nrog khoov, sab dav, sab thickness, sab saum toj lub kaum sab xis, theoretical hnyav, thiab lwm yam, thiab nws tau teev tias lub kaum sab xis steel yuav tsum tsis muaj qhov tseem ceeb torsion.
