Seamless steel kav yog perforated los ntawm tag nrho cov round steel, thiab steel kav uas tsis muaj welds nyob rau saum npoo yog hu ua seamless steel kav.Raws li txoj kev tsim, seamless steel kav yuav muab faib ua kub dov seamless steel kav, txias dov seamless steel kav, txias-draw seamless steel kav, extruded seamless steel kav, thiab sab saum toj kav.Raws li tus ntoo khaub lig-sectional duab, seamless steel kav muab faib ua ob hom: puag ncig thiab tshwj xeeb-puab.Cov kav dej tshwj xeeb muaj xws li square, oval, triangular, hexagonal, melon noob, hnub qub, thiab finned kav.Qhov siab tshaj plaws txoj kab uas hla yog 22000mm thiab qhov tsawg kawg nkaus txoj kab uas hla yog 4 hli.Raws li cov hom phiaj sib txawv, muaj cov kav dej tuab-walled seamless steel kav thiab nyias-walled seamless steel kav.Seamless steel kav yog siv los ua roj av geological drilling kav, tawg kav rau petrochemical kev lag luam, boiler kav, bearing kav, thiab high-precision structural steel kav rau tsheb, tsheb laij teb, thiab aviation.
Seamless steel kav yog dav siv.
1. General-purpose seamless steel kav yog dov los ntawm cov pa roj carbon zoo tib yam steel, low-alloy structural steel los yog alloy structural steel, nrog rau cov khoom loj tshaj plaws, thiab feem ntau yog siv los ua cov kav dej lossis cov khoom siv rau kev xa cov kua dej.
2. Raws li lub hom phiaj sib txawv, nws tuaj yeem muab tau rau hauv peb pawg:
ib.Muab khoom raws li tshuaj muaj pes tsawg leeg thiab txhua yam khoom;
b.Raws li mechanical kev ua tau zoo;
c.Raws li kev ntsuas dej siab.Cov yeeb nkab steel muab raws li pawg a thiab b.Yog tias siv los tiv thaiv cov kua siab, kuj tseem yuav raug kuaj xyuas hydraulic.
3. Cov kav dej tshwj xeeb seamless xws li seamless kav rau boilers, tshuaj thiab hluav taws xob fais fab, seamless steel kav rau geology, thiab seamless kav rau roj av.
Seamless steel kav muaj ib qho hollow seem thiab siv ntau ntau raws li cov kav dej rau kev thauj cov kua dej, xws li cov kav dej thauj cov roj, roj, roj, roj, dej thiab qee yam khoom siv.Piv nrog cov khoom hlau xws li cov hlau puag ncig, cov yeeb nkab steel yog sib dua hauv flexural thiab torsional lub zog thiab yog ib qho kev lag luam steel.Siv dav hauv kev tsim cov khoom siv thiab cov khoom siv kho tshuab, xws li cov kav dej tho roj, tsheb sib kis shafts, tsheb kauj vab ncej, thiab steel scaffolding siv hauv kev tsim kho.Cov yeeb nkab steel yog siv los ua cov nplhaib, uas tuaj yeem txhim kho kev siv cov khoom siv, ua kom yooj yim cov txheej txheem tsim khoom, thiab txuag cov ntaub ntawv thiab kev ua haujlwm.Lub sijhawm ua haujlwm.
Muaj ob txoj haujlwm tseem ceeb rau cov kav dej seamless steel (txias dov thiab kub dov):
①Main ntau lawm txheej txheem ofcccccccc (△ cov txheej txheem tshuaj xyuas tseem ceeb):
Tube billet npaj thiab tshuaj xyuas △ → tube billet cua sov → perforation → tube dov → yeeb nkab reheating → tsau (txo) txoj kab uas hla → tshav kub kho △ → tiav tube straightening → tas → tshuaj xyuas △ (tsis yog-kev puas tsuaj, lub cev thiab tshuaj lom neeg, kev soj ntsuam lub rooj ntev zaum) → nyob rau hauv cia
②Main ntau lawm txheej txheem ntawm txias-dov seamless steel yeeb nkab:
Kev npaj dawb → pickling thiab lubrication → txias dov (kos duab) → kho cua sov → straightening → tiav → tshuaj xyuas → cia
