Hlau rods feem ntau yog siv los ua cov khoom siv raw rau kev txhawb nqa thiab vuam cov qauv ntawm cov pob zeb ua kom muaj zog los yog siv rau kev ua dua tshiab (xws li kos duab, ntsia thawv, thiab lwm yam). Raws li daim ntawv teev cov khoom lag luam steel, cov hlau rods muaj xws li cov pa roj carbon zoo tib yam kub dov hlau rods, hluav taws xob hlau rods, hlau rods rau blasting kab, quenched thiab tempered threaded hlau rods, thiab high-zoo hlau rods. Lub dav siv hlau pas nrig feem ntau yog ib qho zoo tib yam uas tsis muaj carbon steel kub dov hlau qws, los yog hu ua ib tug dog dig hlau pas nrig. Qhov hnyav ntawm lub disc yog 100-200kg, thiab tam sim no nws yog feem ntau dov rau ntawm ib tug tsis-twisted high-speed hlau dov zeb thiab tswj cua txias tom qab dov. Qhov siab tshaj plaws disc hnyav ntawm 5.5-22.0mm inch tuaj yeem ncav cuag 2500kg. Cov xov hlau qub feem ntau yog siv rau kev tsim kho, xaim kos duab, ntim khoom, vuam rods, thiab tsim cov bolts, txiv ntseej, rivets, thiab lwm yam. High-quality hlau pas nrig tsuas yog muab cov khoom zoo carbon steel kub dov hlau pas nrig. Xws li ML08AL, 08F, 10b21, 35Mn, 50Mn, 65, 75Mn, thiab lwm yam. Siv los ua cov khoom siv raw thiab lwm yam khoom siv ntawm cov khoom siv hlau xws li steel hlau, thiab lwm yam zoo steel dov xov hlau. Nws yog kev cai kom suav nrog cov khoom zoo tshaj 8 hli, thiab cov khoom hlau hauv qab 8 hli.
Hlau pas nrig yog ib qho ntawm feem ntau siv steel ntau yam. Tom qab dov, nws tuaj yeem siv ncaj qha rau kev txhim kho thiab welded cov txheej txheem ntawm cov pob zeb ua kom muaj zog, thiab tuaj yeem siv tau tom qab rov ua dua. Piv txwv li, nws yog kos rau hauv ntau yam tshwj xeeb ntawm cov hlau hlau, ces twisted rau hauv steel hlau hlua, woven rau hauv steel hlau mesh, mob rau hauv cov duab, thiab tshav kub-kho rau lub caij nplooj ntoos hlav; los ntawm kub thiab txias forging rau hauv rivets thiab txias-forged thiab dov rau hauv bolts, screws, thiab lwm yam.; Txiav rau hauv kev kho cua sov los ua cov khoom siv kho tshuab lossis cov cuab yeej, thiab lwm yam.
Hlau rods feem ntau yog ua los ntawm cov pa roj carbon zoo tib yam thiab cov pa roj carbon zoo. Raws li cov khoom siv sib txawv ntawm cov khoom siv thiab kev siv, hlau rods muaj xws li cov pa roj carbon tsawg zoo tib yam steel kub dov puag ncig hlau rods, zoo carbon steel hlau rods, carbon vuam pas nrig hlau rods, thiab quenched thiab tempered threaded hlau rods, hlau rods rau hlau. ropes, thiab hlau rods rau piano hlau. Thiab stainless hlau hlau rods, thiab lwm yam. Kuv lub teb chaws yog cov loj tshaj plaws hlau pas nrig tsim nyob rau hauv lub ntiaj teb no, nrog txhua xyoo tso zis accounting rau ntau tshaj ib feem peb ntawm lub ntiaj teb no cov khoom tag nrho. Hlau pas nrig kuj yog kuv lub teb chaws thib ob-loj tshaj plaws steel ntau lawm ntau yam. Qhov kev faib ua feem ntawm domestic steel ntau lawm yeej ib txwm siab. Nyob rau hauv 2007, domestic hlau qws ntau lawm accounted rau kuv lub teb chaws cov hlau ntau lawm. 14.2 feem pua ntawm tag nrho cov zis. Nyob rau hauv xyoo tas los no, kev loj hlob tus nqi ntawm domestic hlau qws tso zis yog yeej ib yam li ntawm domestic crude steel tso zis, uas yog khaws cia nyob ib ncig ntawm 20 feem pua. Los ntawm qhov kev xav ntawm kev ntshuam thiab xa tawm ntawm cov hlau rods, hlau rods tau ntev lawm kuv lub teb chaws lub ntsiab steel export ntau yam, thiab kuj steel ntau yam uas kuv lub teb chaws tau tuav ib tug net export raws li txoj cai, tshwj xeeb tshaj yog nyob rau hauv xyoo tas los no, kev loj hlob ntawm export tau tshwj xeeb. ceev. Hauv xyoo 2007, kuv lub teb chaws tau xa tawm 6.238 lab tons ntawm hlau rods, nce ntawm 684,{14}} tons ntawm xyoo dhau los, ib xyoo-rau-xyoo nce ntawm 12.3 feem pua ; thiab imported 614,{20}} tons, txo 91,{22}} tons ntawm xyoo dhau los. Los ntawm kev xav ntawm domestic hlau qws noj, hlau qws yog dav siv nyob rau hauv kev tsim kho teb. Txij li thaum xyoo 2000, tau tsav los ntawm kev xav tau kev lag luam hauv tsev muaj zog, kev siv hluav taws xob hauv tsev kuj tseem muaj kev loj hlob sai.
