Product Description
Round steel yog ib hom hollow cylindrical hlau khoom, uas yog dav siv nyob rau hauv kev tsim kho, machinery manufacturing, tsheb tsim, zog, tsheb thauj mus los thiab lwm yam lag luam.
Round steel yog tsim los ntawm carbon steel, alloy steel thiab cuab yeej steel.
Ntawm lawv, carbon steel round steel yog hais txog cov hlau nrog cov ntsiab lus carbon nyob rau hauv thaj tsam ntawm 0.20% txog 0.55%.
Cov pa roj carbon steel puag ncig steel yog cov khoom siv hluav taws xob thiab siv tau zoo nrog kev sib txuas zoo, plasticity thiab machinability.
Alloy steel round steel yog hais txog cov hlau uas muaj qee yam ntawm cov ntsiab lus alloying (chromium, manganese, cobalt, boron, molybdenum, vanadium, thiab lwm yam), uas tuaj yeem tau txais lub zog ntau dua, hardness, corrosion kuj thiab hnav tsis kam.
Cov cuab yeej steel Round steel yog ib hom siab -cov cuab yeej siv ceev ceev steel, uas muaj qhov zoo ntawm qhov tawv tawv, siab tawv tawv thiab hnav tsis kam.
Cov txheej txheem ntawm cov hlau puag ncig yog ntau haiv neeg, suav nrog kub dov, kos duab txias thiab kos duab txias.
Ntawm lawv, cov txheej txheem kub dov yog hais txog cov khoom siv hlau rhuab mus rau qhov kub thiab txias, yas deformation los ntawm dov machinery thiab cov khoom siv, nias rau hauv cov qauv sib txawv ntawm cov hlau.
Cov txheej txheem kev kos duab txias yog siv cov khoom siv hlau hlau rau kev kos duab txias, uas tuaj yeem tau txais qhov chaw siab dua rau kev tsim cov khoom precision.
Cov txheej txheem kev kos duab txias yog kos cov hlau hauv qhov chaw txias kom tau txais qhov ntom ntom dua, hardness thiab lub zog.
Daim ntawv thov dav ntawm round steel lies nyob rau hauv nws cov khoom yam ntxwv thiab cov txheej txheem ntau lawm, uas tuaj yeem ua tau raws li cov kev xav tau ntawm kev lag luam sib txawv.
Nyob rau hauv kev tsim kho tej yaam num, round steel yog tsuas yog siv los tsim steel qauv tsev, loj factories, Choj, roj drilling platforms thiab cov khoom siv roj mining.
Nyob rau hauv kev lag luam machinery manufacturing, round steel feem ntau yog siv los ua cov iav, bearings, txuas rods, pins, shafts thiab lwm yam.
Hauv kev lag luam tsheb tsim, cov hlau puag ncig feem ntau yog siv los ua qhov chaw pib, thav duab, ncua kev kaw lus, kev taw qhia mechanisms thiab lwm yam.
Nws kuj yog siv dav hauv lub zog, kev thauj mus los thiab lwm yam lag luam.

Paub meej thiab ntim cov duab
1.Dab tsi yog steel round bar?
Lub steel round bar yogib lub cylindrical metallic bar dav siv hauv kev tsim kho, kev siv hauv tsev, thiab kev tsim khoom. Cov puag ncig no tuaj nyob rau hauv ntau qhov ntau thiab tsawg thiab cov ntaub ntawv haum rau kev lag luam sib txawv. Tus nqi steel sib txawv raws li cov khoom muaj pes tsawg leeg, qhov loj me, thiab kev lag luam xav tau.
2.Lub round bar hu ua dab tsi?
Cov duab ntau tshaj plaws yog round bar (tseem hu uarod), daim duab plaub (xws li square bar, tshwj xeeb ntawm qhov sib npaug ntawm sab), thiab hexagonal bar (feem ntau hu ua hex bar rau luv). Tube thiab cov yeeb nkab zoo sib xws, tab sis muaj qhov chaw hollow thiab tsis yog ib txwm hu ua "bar" hauv kev siv.
3.Dab tsi yog qhov txawv ntawm ib puag ncig bar thiab rebar?
Thawj qhov sib txawv tseem ceeb yuav tsum nco ntsoov yog nyob rau hauv lub zog ntawm ob lub tuav.Lub rebar muaj ntau dua tensile thiab siab tshaj plaws dabtsi yog khoov zog. Cov khoom zoo li no ua rau nws cov khoom zoo tshaj plaws rau fortifying pob zeb. Ua li ntawd, lub rebar tuaj yeem tuav nws cov molecular kev ncaj ncees rau ntau tshaj 100 xyoo.
4.Dab tsi yog tus qauv loj ntawm round bar Tshuag?
Standard diameters muaj los ntawm0.25 "txhua txoj kev mus txog 24"tab sis lwm qhov ntau thiab tsawg tuaj yeem muaj. Hlau tuav muaj nuj nqis rau lawv ntau yam, tshwj xeeb tshaj yog steel bar Tshuag. Cov no yog cov muaj zog, nrog lub siab load bearing muaj peev xwm nrog rau elastic, txo cov peev xwm rau cov ntsiab lus tsis muaj zog thaum lub sij hawm.
5.Yuav ua li cas muaj zog yog ib puag ncig bar?
Strength and Durability: Round bars nthuav tawmzoo heev tensile thiab compressive zog, ua rau lawv haum rau siab - kev siv kev ntxhov siab. Daim ntawv thov kev sib hloov: Lawv cov duab cylindrical tso cai rau lawv ua tau zoo hauv cov ntawv thov kev sib hloov, xws li axles, shafts, thiab lwm yam khoom siv tshuab.
