1. Taw qhia txog seamless steel yeeb nkab
Seamless steel yeeb nkab yog ib hom ncig, square, rectangular steel nrog hollow seem thiab tsis muaj pob qij txha nyob ib ncig ntawm. Seamless steel yeeb nkab yog ua los ntawm steel ingot los yog cov khoom tube dawb paug perforated rau hauv wool raj, thiab ces ua los ntawm kub dov, txias dov los yog txias txias. Seamless steel yeeb nkab muaj qhov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khawm dav siv nyob rau hauv kev tsim khoom ntawm cov qauv thiab cov khoom siv kho tshuab, xws li roj drilling steel scaffolding.
2. Keeb kwm ntawm seamless steel yeeb nkab txoj kev loj hlob
Seamless steel yeeb nkab ntau lawm muaj keeb kwm ze li ntawm 100 xyoo. Cov kwv tij German Manisman thawj zaug tau tsim lub tshuab ob-siab skew thom khwm hauv xyoo 1885, thiab kev tsim lub caij nplooj ntoos hlav dov tshuab hauv xyoo 1891. Xyoo 1903, Swiss RCStiefel tau tsim lub tshuab tsis siv neeg cov yeeb nkab dov (tseem hu ua cov yeeb nkab dov saum toj kawg nkaus) , thiab tom qab ntawd tau tshwm sim cov yeeb nkab txuas txuas txuas thiab cov yeeb nkab thawb lub tshuab thiab lwm cov tshuab txuas ntxiv, pib tsim cov niaj hnub seamless. steel yeeb nkab kev lag luam. Hauv xyoo 1930, ntau yam zoo ntawm cov yeeb nkab steel tau txhim kho los ntawm kev siv peb-siab yeeb nkab dov tshuab, extruding tshuab thiab lub caij txias yeeb nkab dov tshuab. Nyob rau xyoo 1960, vim yog kev txhim kho ntawm cov yeeb nkab txuas txuas txuas ntxiv, qhov tshwm sim ntawm peb-yob perforator, tshwj xeeb tshaj yog daim ntawv thov ntawm nro txo tshuab thiab nruam casting billet ua tiav, txhim kho kev tsim khoom, txhim kho cov yeeb nkab seamless thiab welded yeeb nkab kev sib tw muaj peev xwm. Nyob rau hauv 70's seamless yeeb nkab thiab welded yeeb nkab yog abreast, lub ntiaj teb steel yeeb nkab tso zis ntawm tus nqi ntawm ntau tshaj 5% ib xyoos twg. Txij li thaum xyoo 1953, Tuam Tshoj tau txuas qhov tseem ceeb rau kev tsim cov yeeb nkab steel seamless kev lag luam, thiab tau pib tsim cov txheej txheem ntau lawm rau dov ntau yam loj, nruab nrab thiab me kav. Cov yeeb nkab tooj liab kuj tseem siv ingot cross - dov perforation, raj zeb dov, coil txheej txheem.
3. Kev siv thiab kev faib tawm ntawm seamless steel yeeb nkab
Siv:
Seamless steel yeeb nkab yog ib hom kev lag luam hla ntu hlau, muaj txoj haujlwm tseem ceeb hauv kev lag luam hauv lub tebchaws, dav siv hauv roj av, tshuaj lom neeg kev lag luam, boiler, fais fab chaw nres tsheb, nkoj, machinery manufacturing, tsheb, aviation, aerospace, zog, geology. , kev tsim kho thiab tub rog thiab lwm yam sectors.
Kev faib tawm:
(1) Raws li cov duab seem, nws tau muab faib ua cov yeeb nkab txuas thiab cov yeeb nkab tshwj xeeb
(2) Raws li cov khoom siv: carbon steel yeeb nkab, alloy steel yeeb nkab, stainless hlau yeeb nkab, cov yeeb nkab sib xyaw
(3) Raws li kev sib txuas hom: threaded txuas yeeb nkab, welded yeeb nkab
(4) Raws li cov txheej txheem ntau lawm: kub dov (extrusion, sab saum toj, expansion) yeeb nkab, txias dov (kos duab) yeeb nkab
(5) los ntawm kev siv: boiler yeeb nkab, roj zoo yeeb nkab, yeeb nkab yeeb nkab, qauv yeeb nkab, tshuaj chiv yeeb nkab ......
4, seamless steel yeeb nkab txheej txheem
① Cov txheej txheem tseem ceeb (kev tshuaj xyuas tseem ceeb) ntawm kub dov seamless steel yeeb nkab:
Kev npaj thiab tshuaj xyuas ntawm lub raj tsis muaj → cua sov ntawm lub raj tsis muaj → perforation → dov ntawm lub raj → rov ua kom lub raj hauv khib nyiab → kho (txo) txoj kab uas hla → kho cua sov → straightening ntawm cov yeeb nkab tiav → tiav → tshuaj xyuas (tsis muaj kev puas tsuaj, lub cev thiab tshuaj lom neeg, rooj tshuaj xyuas) → cia
② Txias dov (kos duab) seamless steel yeeb nkab txheej txheem ntau lawm
Kev npaj dawb → pickling lubrication → txias dov (kos duab) → kho cua sov → straightening → tiav → tshuaj xyuas.
5. Cov txheej txheem ntau lawm khiav daim ntawv ntawm kub dov seamless steel yeeb nkab yog raws li nram no:
