Lub Txheej Txheem Ntau Lawm Ntawm Cov Kav Hlau
Cov txheej txheem ntau lawm ntawm cov kav hlau steel tsuas yog poob rau hauv ob pawg: seamless steel kav thiab welded kav dej). Cov txheej txheem tshwj xeeb sib txawv nyob ntawm cov ntaub ntawv, kev siv thiab kev ua tau zoo.
Seamless Cov Yeeb Nkab Cov Khoom Siv
Seamless steel kav yog kev ua tiav los ntawm cov khoom hlau billets rau hauv lub kaus mom khoob tsis muaj welds thiab haum rau cov kev kub siab, siab lossis huab cua huab cua.
- Kub-Rug Seamless Steel Yeeb Nkab
- Cov Khoom Siv Khoom Siv Raw Ua: Thaum tshav kub kub hloov hlau los yog hlau billits rau lub xeev yas (kwv yees li 1200 degree).
- Tho: Lub billet yog chob rau hauv lub plab khoob los ntawm tus ntoo khaub lig-dov tho kev siv lub tshuab (xws li Mannesmann Tho txoj kev).
- Yeeb Nkab Rolling: Cov yeeb nkab ntxhib yog thinned thiab ntev los ntawm ib lub tshuab kub rolling (xws li ib tug txuas txuas ntxiv zeb lossis cov yeeb nkab rub tshuab).
- Sizing: sab nraud ntawm txoj kab uas hla thiab phab ntsa tuab qhov raug yog tswj los ntawm lub tshuab sizing sizing.
- Txias thiab ncaj: tom qab txias, ncaj thiab txiav kom tshem tawm cov kev teev rau saum npoo av.
- Kev Kho Cua Sov: Muab kev kho mob los yog annealing txhim kho cov khoom siv mechanical.
- Kev tshuaj xyuas: Qhov thaiv kom pom tau, qhov txuas kev kuaj xyuas, hydrostatic kuaj, thiab lwm yam.
- Khaub thuas-dov \/ txias-kos-kos seamless steel leeg
- Cov Khoom Siv Raw: Kub-Rolled Tube Billet.
- Pickling: tshem cov oxide txheej.
- Cold colling \/ cool plawg: dov lossis kos duab ntawm chav tsev kub los txhim kho qhov raug thiab qhov chaw ua tiav.
- Kev kho cua sov: annealing tshem tawm ua haujlwm tawv.
- Xov: Ncaj, txiav, soj ntsuam.
Cov txheej txheem ntau lawm ntawm Welded Hlau Kav
Welded kav yog tsim los ntawm cov phaj dov thiab tom qab ntawd welded, featuring high efficiency thiab tus nqi qis, thiab tsim nyog rau cov chaw qis.
- Ncaj nkhaus Welded yeeb nkab (LSAWW \/ ERW)
Cov Khoom Siv Raw:Kub-dov lossis txias-dov hlau daim hlau \/ STEEL STRIPS.
Kev sib sau: Yob rau hauv lub raj ci raj (jcoe tsim, cov menyuam khoov kev sib sau ua ke).
Vuam:
High-furnighency vuam (ERW): Nws siv high-zaus tam sim no los yaj tus npoo tsis muaj kev xav tau cov khoom siv vuam.
Submerged Arc Vuam (pom): Nws yog siv rau tuab-walled thiab yog tiv thaiv los ntawm flux.
Laser Vuam: Siab Precision, Siv rau cov raj ntsa nyias nyias.
Weld Kho: Tshem tawm sab hauv thiab sab nraud pov tseg, thiab txo kev ntxhov siab los ntawm kev sib tsoo lossis kev kho cua sov.
Sizing thiab ncaj: Tswj qhov ntev thiab ncaj.
Kev kuaj xyuas: Weld seKuv yog qhov khuam kom pom (ultrasonic, xoo hluav taws xob), hydrostatic qhov kev xeem.
- Muab kauv welded yeeb nkab
- Cov Khoom Siv Raw: Ntev Steel Sawb Chev.
- Muab kauv thawj: cov kab hlau yog coiled rau hauv cov hlab ntawm ib tug kauv kaum thiab welded ib txhij.
- Nta: nws tuaj yeem tsim cov kav dej loj loj, tab sis Weld Seams ntev thiab cov kev ntxhov siab nyob hauv siab.
