Cov yam ntxwv tuag: Qhia qhov tsis sib xws lossis tsis tu ncua hauv zos indentation thiab nqaij ntawm qhov ntev ntawm cov yeeb nkab steel. Cov duab yog nuclear, sawb, kab rov tav siab raug mob, tilted daim tawv nqaij, fragmented, hlau dumb-shaped, thiab lwm yam.
ua rau:
① Qhov saum npoo ntawm cov rolls tiav ntawm lub tensor yog nplaum rau saum npoo ntawm yob.
② Scars lossis lwm lub cev txawv teb chaws raug nias rau ntawm cov yeeb nkab steel kom poob.
③ Lub thermal steel yeeb nkab raug mob los yog khawb.
④ Trocaying raug mob thiab luam tawm los ntawm transverse txav los yog sawing ntaus ntawv.
tus txiav txim:
General tube: Wall thickness ≤8mm indentation depth does not exceed 90% of negative deviations, and wall thickness>80% ntawm 80% ntawm qhov tob ntawm 8mmm indentation yuav tsum tsis pub tshaj 1.0mm.
Boiler raj: Tus nqi siab tshaj plaws ntawm phab ntsa thickness yog 0.6mm.
Roj suite: Qhov tob indentation yuav tsum tsis pub tshaj ib nrab ntawm phab ntsa thickness bias. Qhov siab tshaj plaws tus nqi ntawm qhov tob ntawm S Loj dua los yog sib npaug rau 10mm tsis tshaj 0.6mm, thiab qhov tob ntawm qhov siab tshaj plaws ntawm S<<10mm does not exceed 0.5mm.
Ncaj nraim
Cov yam ntxwv tsis xws luag: grooves uas yog vertically faib raws cov yeeb nkab steel.
Ua rau: Thaum lub dov kub qis, cov hlau nplaum sab saum toj khawb lub puab nto ntawm cov yeeb nkab steel, thiab lub taub hau sab saum toj yog hnyav heev. Tsis zoo lubrication los yog hnyav hnyav.
tus txiav txim:
Cov raj dav dav: Qhov tob ntawm txoj kev sab nrauv tsis tshaj 9 0% ntawm phab ntsa thickness sib txawv ntawm 90%, thiab qhov tob ntawm txoj kev sab hauv tsis tshaj 70% ntawm phab ntsa thickness bias thiab qhov tob ntawm qhov tob 0.6mm.
Boiler kav thiab roj suite: Qhov tob ntawm txoj kab ncaj nraim yuav tsum tsis pub tshaj 5% ntawm phab ntsa tuab, thiab qhov siab tshaj plaws tsis pub tshaj 0.4mm.
Tsis raws cai
Cov yam ntxwv tuag: Qhov hla ntawm cov yeeb nkab steel tsis yog puag ncig.
Ua rau: Kev kho tsis raug ntawm lub zog clamping thaum sawing, kev teeb tsa tsis raug ntawm cov khib nyiab tiav thiab ua haujlwm khib ntawm lub tensor. tsis tsim nyog.
Cov phab ntsa tsis sib xws
Cov yam ntxwv tuag: Qhov siab tshaj plaws ntawm cov phab ntsa thickness ntawm cov yeeb nkab steel ntawm tib seem, qhov tsawg kawg nkaus tus nqi tshaj qhov zoo sib txawv thiab tsis zoo sib txawv, los yog lub npe ntawm nominal phab ntsa thickness yog ± 8-10% (qhov txwv sab sauv ntawm cov phab ntsa tuab yog muab tso rau hauv cov phab ntsa nyias nyias)
Yog vim li cas: Lub perforation yuav tsum tau raws li qhov yuav tsum tau. Lub raj kawg saum npoo yog incisive, cua sov ntawm lub raj tsis zoo, lub raj yog rhuab tsis sib xws, cov khoom siv perforated tsis kho kom raug, thiab lub tshuab dov tsis kho kom zoo.
khoov
Cov yam ntxwv tsis zoo: Cov yeeb nkab steel tsis ncaj raws qhov ntev ntawm cov yeeb nkab steel, thiab qhov kawg ntawm cov yeeb nkab steel yog khoov.
Yog vim li cas: Ob peb lub qhov kawg-type central kab ntawm tensor yog misplaced. Kev faib tawm ntawm refined dov pores nyob rau hauv lub tensor yog tsis tsim nyog. Txoj kev txias ntawm Zhang Duan raj tsis tsim nyog lossis qhov kub thiab txias siab dhau thaum txiav.
