Feem ntau, cov hlau kaum sab xis uas xa tawm thiab xa tawm yog raws li cov lus qhia uas xav tau, thiab nws cov qib hlau yog cov hlau carbon sib xws. Nws kuj yog cov hlau kaum sab xis. Ntxiv rau tus lej qhia tshwj xeeb, tsis muaj cov koob tshuaj thiab kev ua tau zoo tshwj xeeb. Qhov ntev ntawm cov hlau kaum sab xis raug muab faib ua qhov ntev ruaj khov thiab qhov ntev ob npaug. Qhov ntau thiab tsawg xaiv qhov ntev ruaj khov ntawm cov hlau kaum sab xis hauv tsev yog 3-9m, 4-12m, 4-19m thiab 6-19m raws li tus lej qhia tshwj xeeb. Qhov ntau thiab tsawg xaiv qhov ntev ntawm cov hlau kaum sab xis ua nyob rau hauv Nyiv yog 6-15m.

Qhov siab ntawm cov hlau tsis sib npaug yog xam raws li qhov ntev thiab dav ntawm cov hlau tsis sib npaug. Nws yog hais txog cov hlau uas muaj qhov sib npaug thiab qhov ntev tsis sib npaug ntawm ob sab. Nws yog ib qho ntawm cov hlau tsis sib npaug. Nws qhov ntev ntawm sab yog 25mm × 16mm ~ 200mm × l25mm. Nws yog dov los ntawm lub tshuab dov kub.

Cov lus qhia ntawm cov hlau tsis sib npaug dav dav yog: ∟ 50 * 32 — ∟ 200 * 125, thiab cov tuab yog 4-18 hli.

Cov hlau tsis sib npaug yog siv dav hauv ntau yam qauv hlau, choj, kev tsim tshuab thiab kev tsim nkoj, ntau yam qauv tsev thiab cov qauv engineering, xws li cov ntoo tsev, choj, cov pej thuam kis, cov tshuab hoisting thiab kev thauj mus los, nkoj, cov cub tawg kev lag luam, cov pej thuam teb, cov thawv khib thiab cov tsev rau khoom.

Ntshuam thiab xa tawm

Tuam Tshoj xa khoom thiab xa tawm cov hlau kaum sab xis hauv qee cov pawg, feem ntau yog los ntawm Nyiv Pooj thiab Western Europe. Cov khoom xa tawm feem ntau yog xa tawm mus rau Hong Kong thiab Macao, Southeast Asia, Latin America thiab Arab lub teb chaws. Cov tuam txhab tsim khoom xa tawm feem ntau yog cov chaw tsim khoom hlau (rolling mills) hauv Liaoning, Hebei, Beijing, Shanghai, Tianjin thiab lwm lub xeev thiab nroog. Peb yog lub Hoobkas hlau hauv Tianjin.

Cov hlau kaum sab xis uas xa tuaj rau txawv teb chaws feem ntau yog cov hlau kaum sab xis loj thiab me thiab cov hlau kaum sab xis uas muaj cov duab tshwj xeeb, thiab cov hlau kaum sab xis uas xa tawm feem ntau yog cov hlau kaum sab xis nruab nrab, xws li No. 6, No. 7, thiab lwm yam.

Qhov zoo ntawm qhov tsos

Qhov zoo ntawm cov hlau kaum sab xis yog teev nyob rau hauv tus qauv. Peb lub Hoobkas nruj me ntsis yuav tsum tsis txhob muaj qhov tsis zoo thaum siv, xws li delamination, scab, tawg, thiab lwm yam.

Qhov ntau yam kev tso cai ntawm kev hloov pauv geometric ntawm lub kaum sab xis steel kuj tau teev tseg hauv tus qauv, feem ntau suav nrog kev khoov, qhov dav ntawm sab, qhov tuab ntawm sab, lub kaum sab saud, qhov hnyav theoretical, thiab lwm yam, thiab nws tau teev tseg tias lub kaum sab xis steel yuav tsum tsis muaj qhov torsion tseem ceeb.
