Dab tsi yog qhov txawv ntawm rebar thiab round steel?
Rebar belongs rau lub me me steel hlau, thawj zaug siv nyob rau hauv lub cev pob txha ntawm reinforced pob zeb cov tswv cuab. Hauv kev siv, nws yuav tsum muaj qee yam kev siv zog, khoov deformation zog thiab txheej txheem vuam cov khoom. Round steel hais txog ib ntu ntawm cov hlau ntev ntev, cov hlau puag ncig tau muab faib ua kub dov, forged thiab txias kos peb yam. Qhov sib txawv ntawm rebar thiab puag ncig steel yog qhov saum npoo yog nruab nrog ntev tav thiab transverse tav, feem ntau nrog ob longitudinal tav thiab transverse ribs tusyees faib raws qhov ntev.
Nyob rau hauv kev tsim kho engineering, puag ncig steel thiab rebar yog cov npe nrov rau ntau hom steel tuav, thiab qhov sib txawv ntawm lawv feem ntau muaj tsib lub ntsiab lus hauv qab no:
1. Cov duab sib txawv. Sab nrauv ntawm puag ncig steel yog du; Sab nrauv ntawm lub rebar muaj ib tug kauv tav.
2. Cov qauv tsim khoom sib txawv. Nyob rau hauv tus qauv tam sim no, round steel yog hais txog HPB235 steel bar, nws cov qauv tsim yog "kub dov du steel bar rau cov pob zeb muaj zog" (GB13013); Rebar ib txwm hais txog HRB335 thiab HRB400 qib rebar, nws cov txheej txheem tsim khoom yog "Kub dov ribbed steel bar rau cov pob zeb muaj zog" (GB1499).
3. Cov qib sib txawv ntawm kev siv zog. Lub zog tsim ntawm cov hlau puag ncig (HPB235) yog 210MPa; Lub zog ntawm rebar yog siab dua cov hlau puag ncig, thiab lub zog tsim ntawm HRB335 yog 300MPa; HRB400 muaj lub zog tsim ntawm 360MPa.
4. Ntau hom hlau (sib txawv tshuaj muaj pes tsawg leeg). Round steel (HPB235) yog carbon steel, steel yog Q235; Rebar yog cov hlau tsis tshua muaj hlau, HRB335 steel bar yog 20MnSi (20 manganese silicon); HRB400 qib rebar yog 20MnSiV lossis 20MnSiNb lossis 20MnTi, thiab lwm yam.
5. Cov khoom sib txawv ntawm lub cev thiab cov khoom siv kho tshuab. Vim muaj cov tshuaj sib txawv thiab lub zog ntawm steel tuav, muaj qhov sib txawv ntawm lub cev thiab cov khoom siv kho tshuab. Qhov txias bending kev ua tau zoo ntawm cov hlau puag ncig yog qhov zoo dua, tuaj yeem yog 180 degrees ntawm kev khoov nuv, rebar tuaj yeem tsuas yog 90 degrees ntawm ncaj nuv; Lub weldability ntawm round steel yog zoo dua, thiab zoo tib yam carbon electrode yuav siv tau, thiab tsawg alloy electrode yuav tsum tau siv rau rebar. Rebar yog zoo dua li cov hlau puag ncig hauv toughness thiab qaug zog kuj.
Round steel muaj nuj nqi: 5. Round steel loj dua 25 hli, feem ntau yog siv rau kev tsim cov khoom siv tshuab lossis seamless steel blanks.
Cov khoom tseem ceeb ntawm cov hlau: 42CrMo4 round steel, 40Mn2 round steel, T12 steel, 45 round steel
Alloy structural steel: 42CrMo4(1.7225) Tus qauv Executive: EN 10083/3-2006, American AISI standard 4140 steel txhim kho ntau yam, cov hlau muaj kev ua haujlwm zoo, yooj yim polishing, yooj yim rau tom, thiab tuaj yeem electroplated.
Round steel yog ib tug ntev, khoom steel bar nrog ib puag ncig cross-section. Nws cov specifications yog qhia nyob rau hauv millimeters ntawm txoj kab uas hla, xws li "50" uas txhais tau hais tias round steel nrog ib txoj kab uas hla ntawm 50 hli.
Round steel muab faib ua kub dov, forged thiab txias kos peb yam.
Cov yam ntxwv thiab cov peev txheej ntawm daim ntawv thov: siab zog, siab hardenability, zoo toughness, me me deformation thaum lub sij hawm quenching, siab creep zog thiab ntev lub zog ntawm kub. Nws yog siv los tsim cov forgings uas yuav tsum tau muaj zog dua thiab loj dua quenching seem dua li 35CrMo steel, xws li cov iav loj rau kev sib tsoo, supercharger kis iav, rear ncej, txuas pas nrig thiab lub caij nplooj ntoos hlav clamp nrog kev thauj khoom zoo, thiab tseem tuaj yeem siv rau drilling yeeb nkab pob qij txha. thiab cov cuab yeej nuv ntses hauv cov dej tob tob hauv qab 2{{2}00m. ① Tsim nyog rau kev sib sau ua hluav taws xob thiab hluav taws xob pwm. ② Yas pwm, pwm puag. Cov tshuaj muaj pes tsawg leeg: Carbon C: 0.38 ~ {{10}}.45 Si: Tsawg dua lossis sib npaug rau 0.40 Manganese Mn: 0.60 ~ 0.90 Sulfur S: tso cai cov ntsiab lus seem tsawg dua lossis sib npaug rau 0.035 Phosphorus P: tso cai cov ntsiab lus seem tsawg dua lossis sib npaug rau 0.035 Chromium Cr: 0.90 ~ 1.20
Nickel Ni: Tso cai cov ntsiab lus seem tsawg dua lossis sib npaug rau {{0}}}030 Copper Cu: tso cai cov ntsiab lus seem tsawg dua lossis sib npaug rau 0.030 Molybdenum Mo: 0.15 ~ 0.30
Mechanical zog; Tensile zog σb (MPa): Ntau dua lossis sib npaug rau 1080 (110)
