Loj txoj kab uas hla stainless hlau chaw tsim tshuaj paus kev muag khoom
Stainless hlau yeeb nkab yog ib hom hollow ntev round steel, uas yog dav siv nyob rau hauv industrial kis pipelines xws li roj av, tshuaj kev lag luam, kev kho mob, khoom noj khoom haus, lub teeb kev lag luam, mechanical instruments thiab mechanical structural Cheebtsam. Tsis tas li ntawd, thaum lub zog khoov thiab torsional zoo ib yam, qhov hnyav yog lub teeb, yog li nws kuj tau siv dav hauv kev tsim khoom ntawm cov khoom siv tshuab thiab cov qauv tsim. Nws kuj tseem siv tau los ua rooj tog zaum, chav ua noj, thiab lwm yam.
Brinell, Rockwell thiab Vickers hardness indexes feem ntau yog siv los ntsuas qhov hardness ntawm stainless hlau kav.
Brinell hardness yog cov qauv siv dav tshaj plaws rau cov yeeb nkab steel hlau. Indentation txoj kab uas hla feem ntau yog siv los qhia qhov hardness ntawm cov khoom, uas yog intuitive thiab yooj yim. Txawm li cas los xij, nws tsis muaj feem xyuam rau cov kav hlau uas muaj tawv lossis nyias hlau.
Rockwell hardness test ntawm stainless hlau yeeb nkab yog tib yam li Brinell hardness test, uas yog ib qho kev xeem indentation. Qhov txawv yog tias nws ntsuas qhov tob ntawm qhov indentation. Rockwell hardness test yog ib txoj kev siv dav, uas HRC tsuas yog thib ob rau Brinell hardness Hb hauv cov qauv steel yeeb nkab. Rockwell hardness tuaj yeem siv los ntsuas cov ntaub ntawv hlau los ntawm qhov muag heev mus rau qhov nyuaj heev. Nws ua rau qhov tsis zoo ntawm Brinell txoj kev. Nws yog qhov yooj yim dua li Brinell txoj kev thiab tuaj yeem nyeem ncaj qha tus nqi hardness los ntawm lub xov tooj ntawm lub tshuab hardness. Txawm li cas los xij, vim nws qhov me me indentation, tus nqi hardness tsis yog raws li Brinell txoj kev.
Vickers hardness test ntawm stainless hlau yeeb nkab kuj yog ib txoj kev kuaj indentation, uas yuav siv tau los txiav txim siab hardness ntawm nyias hlau cov ntaub ntawv thiab nto txheej. Nws muaj qhov zoo ntawm Brinell thiab Rockwell txoj hauv kev thiab kov yeej lawv qhov tsis txaus ntseeg, tab sis nws tsis yooj yim li Rockwell txoj kev. Vickers txoj kev tsis tshua siv nyob rau hauv cov qauv steel yeeb nkab.
W-b75 Vickers hardness tester tuaj yeem siv rau cov kav dej tsis muaj steel hlau uas muaj lub taub sab hauv ntau dua 6.0mm thiab phab ntsa thickness tsawg dua 13mm. Nws yog qhov nrawm heev thiab yooj yim, thiab yog qhov tsim nyog rau kev kuaj xyuas cov kav dej tsis muaj steel hlau sai thiab tsis muaj kev puas tsuaj. Rau cov kav hlau tsis muaj steel nrog lub taub sab hauv siab dua 30 hli thiab phab ntsa thickness ntau dua 1.2 hli, Rockwell hardness tester yuav tsum tau siv los ntsuas HRB thiab HRC hardness. Rau cov kav hlau tsis muaj steel nrog lub taub sab hauv siab dua 30 hli thiab phab ntsa thickness tsawg dua 1.2 hli, qhov saum npoo Rockwell hardness tester yuav tsum tau siv los kuaj HRT lossis hrn hardness. Rau cov kav hlau tsis muaj steel nrog lub taub sab hauv tsawg dua 0mm thiab ntau dua 4.8mm, siv Rockwell hardness tester tshwj xeeb rau cov kav dej los kuaj hr15t hardness. Thaum lub puab txoj kab uas hla ntawm stainless hlau yeeb nkab yog ntau tshaj 26 hli, Rockwell los yog nto Rockwell hardness tester kuj siv tau los ntsuam xyuas lub hardness ntawm lub puab phab ntsa ntawm cov yeeb nkab.
Cov yeeb nkab steel hlau tau muab faib ua cov pa roj carbon zoo tib yam, cov yeeb nkab zoo carbon steel yeeb nkab, cov yeeb nkab steel hlau, cov yeeb nkab steel hlau, cov yeeb nkab steel, cov yeeb nkab steel hlau, cov kav dej bimetallic composite kav, coated thiab coated kav kom txuag tau cov hlau muaj txiaj ntsig thiab ua tau raws li qhov tshwj xeeb. kev xav tau. Stainless hlau kav muaj ntau yam, sib txawv siv, sib txawv kev xav tau thiab ntau lawm txoj kev. Tam sim no, sab nraud txoj kab uas hla ntawm cov kav hlau yog 0.1-4500mm thiab phab ntsa thickness ntau yog 0.01-250mm. Txhawm rau kom paub qhov txawv ntawm nws cov yam ntxwv, cov kav hlau steel feem ntau raug faib raws li cov hauv qab no.
Stainless hlau yeeb nkab yuav muab faib ua seamless yeeb nkab thiab welded yeeb nkab raws li hom ntau lawm. Seamless steel yeeb nkab tuaj yeem muab faib ua cov yeeb nkab kub dov, cov yeeb nkab txias dov, cov yeeb nkab txias thiab cov yeeb nkab extruded. Kev kos duab txias thiab txias dov yog cov txheej txheem thib ob ntawm cov yeeb nkab steel; Welded yeeb nkab yog muab faib ua ncaj seam welded yeeb nkab thiab kauv welded yeeb nkab.
Stainless hlau yeeb nkab tuaj yeem muab faib ua cov yeeb nkab puag ncig thiab cov yeeb nkab tshwj xeeb raws li cov duab ntoo khaub lig. Cov raj tshwj xeeb muaj xws li cov raj duab plaub, cov raj rhombic, cov raj elliptical, cov raj hexagonal, cov raj octagonal thiab ntau yam ntoo khaub lig-section asymmetric raj. Cov yeeb nkab tshwj xeeb yog siv dav hauv ntau yam qauv, cov cuab yeej thiab cov khoom siv tshuab. Piv nrog cov yeeb nkab ncig, cov yeeb nkab tshwj xeeb feem ntau muaj lub sijhawm loj ntawm inertia thiab seem modulus, thiab muaj kev khoov loj thiab torsion tsis kam, uas tuaj yeem txo qhov hnyav ntawm cov qauv thiab txuag hlau.
Stainless hlau yeeb nkab tuaj yeem muab faib ua cov yeeb nkab sib npaug thiab sib txawv ntawm cov yeeb nkab raws li qhov profile duab. Cov kav dej sib txawv muaj xws li cov kav dej conical, cov kav dej thiab cov kav ntu ntu ntu.
Stainless hlau yeeb nkab tuaj yeem muab faib ua cov yeeb nkab du thiab threaded yeeb nkab (threaded steel yeeb nkab) raws li lub xeev ntawm cov yeeb nkab kawg. Threading yeeb nkab kuj tseem tuaj yeem muab faib ua cov yeeb nkab zoo tib yam (cov yeeb nkab rau kev xa tawm tsis tshua muaj siab xws li dej thiab roj, uas txuas nrog tib yam cylindrical los yog conical yeeb nkab xov) thiab cov yeeb nkab tshwj xeeb threaded (cov yeeb nkab rau roj av thiab geological drilling, uas txuas nrog tshwj xeeb. xov rau tseem ceeb threading yeeb nkab). Rau qee cov kav dej tshwj xeeb, txhawm rau tsim kom muaj kev cuam tshuam ntawm cov xov ntawm lub zog ntawm cov yeeb nkab kawg, cov yeeb nkab kawg thickening (sab hauv thickening Sab nraud thickening lossis sab hauv thiab sab nraud thickening).
Raws li lub hom phiaj, nws tuaj yeem muab faib ua cov roj zoo yeeb nkab (casing, roj yeeb nkab thiab laum yeeb nkab), cov yeeb nkab yeeb nkab, cov yeeb nkab boiler, cov khoom siv hluav taws xob, cov yeeb nkab hydraulic, cov yeeb nkab roj kheej kheej, cov yeeb nkab geological, cov yeeb nkab yeeb nkab, cov yeeb nkab, cov yeeb nkab, cov yeeb nkab, cov yeeb nkab, cov yeeb nkab, cov yeeb nkab, cov yeeb nkab, cov yeeb nkab, geological yeeb chiv yeeb nkab, roj av cracking yeeb nkab) thiab marine yeeb nkab.
Raw cov ntaub ntawv - strip splitting - welded yeeb nkab ua - kawg kho - polishing - Kev tshuaj xyuas (tsam luam ntawv) - ntim - xa khoom (warehousing) (zoo nkauj welded yeeb nkab).
