Kev loj hlob keeb kwm ntawm Seamless Steel Yeeb Nkab
Seamless steel yeeb nkab ntau lawm muaj keeb kwm ntawm ze li 100 xyoo. Lub German Manesmann Cov kwv tij ua ntej tsim ob yob hla dov Piercer hauv 1885, thiab lub sijhawm ua Swiss Rc steel (tseem hu ua cov yeeb nkab hluav taws xob). Tom qab hais tias, ntau lub tshuab txuas txuas ntxiv xws li nruam yeeb nkab zeb thiab cov kav hlau jaming tshuab tshwm, uas pib tsim cov khoom siv tshiab tshiab steelless steel yeeb nkab. Thaum xyoo 1930, vim muaj peb yob yeeb nkab dov zeb, extruder thiab peragic txias dov zeb, ntau yam thiab zoo ntawm cov kav hlau tau txhim kho. Nyob rau hauv lub xyoo 1960, vim muaj kev txhim kho cov yeeb nkab cov yeeb nkab txuas ntxiv, tshwj xeeb yog kev ua tiav ntawm peb txoj kev sib tw ntawm seamless yeeb thiab welded yeeb nkab tau txhim kho. Hauv xyoo 1970, seamless cov yeeb nkab thiab welded yeeb nkab tau khaws cia nrawm, thiab lub ntiaj teb steel yeeb nkab zis nce qib ntau dua 5% ib xyoos. Txij li xyoo 1953, Tuam Tshoj tau txuas nrog qhov tseem ceeb rau kev txhim kho cov yeeb nkab steel yeeb nkab kev lag luam, thiab tau tsim cov khoom tsim khoom rau cov yob txhua yam ntawm cov kav nruab nrab, nruab nrab. Feem ntau, tooj liab cov yeeb nkab tseem hloov cov txheej txheem ntawm billet hla dov thiab tho.
Daim ntawv thov thiab kev faib tawm ntawm Seamless steel yeeb nkab
Daim Ntawv Thov:
Seamless steel yeeb nkab yog ib hom kev lag luam Tshooj Hlau, uas yog lub luag haujlwm tseem ceeb hauv kev lag luam hauv tebchaws. Nws yog dav siv hauv roj av, kev lag luam chem, boiler, chaw nres tsheb fais fab, tshuab, kev tsim kho, kev lag luam kev ua tub rog thiab lwm yam tub rog.
Kev faib tawm:
① Raws li cov seem ntawm cov duab: Round ntu yeeb nkab thiab cov yeeb nkab seem.
② Raws li cov khoom siv: carbon hlau yeeb nkab, cov yeeb nkab hlau alloy, hlau steel hlau thiab cov yeeb nkab composite.
③ Raws li kev sib txuas hom: xov txuas sib txuas yeeb nkab thiab welded yeeb nkab.
④ Raws li kev tsim khoom: Kub Rolling (Extrusion, Jacking thiab nthuav dav) yeeb nkab (kos duab) yeeb nkab.
⑤ Raws li lub hom phiaj: Boiler yeeb nkab, roj yeeb nkab, cov yeeb nkab cov yeeb nkab, cov yeeb nkab txheem chiv thiab cov tshuaj chiv.
