1. Kev qhia txog ntawm seamless steel yeeb nkab
Seamless steel yeeb nkab yog ib hom licular, square, plaub hau hlau nrog ntu hollow thiab tsis muaj pob qij txha ib ncig. Seamless steel yeeb nkab yog ua los ntawm cov hlau ingot lossis cov raj khoom tawv dawb rau hauv cov raj kub, thiab tom qab ntawd ua los ntawm kub dov, txias dov, txias puv lossis txias kos duab. Seamless steel yeeb nkab muaj ib ntu Hollow, muaj ntau tus neeg siv cov yeeb nkab thiab lwm lub qhov taub khov kho thiab khoom siv hluav taws xob, yog hom kev lag luam ntawm cov hlau, Dav siv nyob rau hauv kev tsim cov txheej txheem txheej txheem thiab tshuab siv tshuab, xws li roj drilling steel scaffolding hlau scaffolding hlau scaffolding hlau scaffolding hlau scaffolding hlau scaffolding hlau scaffolding hlau scaffolding.
2. Keeb kwm ntawm Seamless Steel Yeeb Nkab Txhim Kho
Seamless steel yeeb nkab ntau lawm muaj keeb kwm ntawm ze li 100 xyoo. Lub Tshuab German Manisman ua ntej tsim ob-siab skew rollcing tshuab xyoo 1881. Xyoo 1903, Lub pob yeeb siv hluav taws xob kaw tau tshuab (tseem hu ua cov yeeb nkab dov rau lub cav) , thiab tom qab ntawd tau tshwm sim cov yeeb nkab txuas Rolling tshuab thiab cov yeeb nkab muag laub tshuab thiab lwm cov tshuab txuas ntxiv, pib ua cov yeeb nkab niaj hnub sib xws. Thaum xyoo 1930, ntau yam zoo, ntau yam zoo ntawm cov yeeb nkab steel tau txhim kho los ntawm kev kawm tau peb-siab yeeb nkab yob tshuab, extruding tshuab thiab tej yam txias txias yeeb nkab dov rau tshuab. Nyob rau hauv lub xyoo 1960, vim muaj kev txhim kho cov yeeb nkab sib txuas, tshwj xeeb yog kev ua haujlwm ntawm kev tsim khoom, txhim kho cov yeeb nkab seamless thiab welded yeeb nkab kev sib tw muaj peev xwm. Nyob rau hauv 70 lub seamless yeeb nkab thiab welded yeeb nkab yog abreast, lub ntiaj teb steel yeeb nkab tawm ntawm ntau dua 5% ib xyoos. Txij xyoo 1953, Tuam Tshoj tau txuas nrog qhov tseem ceeb rau kev txhim kho cov yeeb nkab ntawm cov yeeb nkab steel siv rau ntau ntau loj, nruab nrab thiab kav dej me. Tooj liab yeeb kuj tseem siv Ingot Hla - dov perforation, raj
3. Siv thiab kev faib tawm ntawm Seamless Steel Yeeb Nkab
Siv:
Seamless steel yeeb nkab yog ib hom kev lag luam tus kab ke hlau, muaj qhov chaw nres tsheb tseem ceeb, lub nkoj hluav taws xob, kev tsim tshuaj, thauj khoom, lub zog, hluav taws xob, kev lag luam , kev tsim kho thiab tub rog thiab lwm yam haujlwm.
Kev faib tawm:
(1) Raws li cov ntu, nws tau muab faib ua ke cov yeeb nkab kauj thiab tshwj xeeb zoo li cov yeeb nkab
(2) Raws li cov khoom siv: carbon hlau yeeb nkab, alloy steel yeeb nkab, hlau steel hlau, yeeb nkab composite
(3) Raws li kev sib txuas hom: xov txuas sib txuas yeeb nkab, welded yeeb nkab
(4) Raws li txoj kev ntau lawm: Kev zam kub (Extrusion, nthuav dav) yeeb nkab, txias dov (kos duab) yeeb nkab
(5) LOS SIV: Boiler Yeeb Nkab, Roj Yeeb Nkab, Roj Yeeb Nkab, Cov Qauv Yeeb Nkab, Yeeb Nkab Chiv Yeeb ......
4, Seamless Hlau Yeeb Nkab Cov Txheej Txheem
Process Txheej txheem ntau lawm (cov txheej txheem tshuaj xyuas tseem ceeb) ntawm kub dov seamless steel yeeb (
Kev npaj thiab tshuaj xyuas ntawm lub raj dawb paug → cua sov ntawm raj dawb → firsting ntawm cov ntaub pua chaw → firishing ntawm ua tiav cov yeeb nkab → Ua hauj lwm kub, lub cev thiab tshuaj lom neeg, Cov lus tshuaj xyuas) → cia
② Tus Rolled Txias (kos duab) Seamless Hlau Yeeb Nkab Cov Txheej Txheem Ntau Lawm
Kev npaj dawb paug → brouration → rolling colling (kos duab) → Kev kho kom sov → Wires Wires → Tee Soj Ntsuam.
5. Cov txheej txheem ntau lawm Flow chartal ntawm cov yeeb nkab seamless steel yog li hauv qab no:
