Dab tsi yog cov txheej txheem tseem ceeb thiab kev tswj cov txheej txheem ntawm Titanium Cold Rolling Ribbing?

Txias- dovtitanium ntawv thiab stripsyog cov ntaub ntawv tseem ceeb, thiab lawv cov flatness ncaj qha cuam tshuam rau kev ua haujlwm tom ntej thiab kev ua haujlwm ntawm cov khoom kawg. Titanium cov ntaub ntawv yog nquag ua hauj lwm hardening, tsis tshua muaj elastic modulus thiab muaj zog anisotropy. Cov teeb meem xws li ribbing, ntug nthwv dej thiab wrinkles feem ntau tshwm sim thaum lub caij txias dov, ntawm cov ribbing yog feem ntau.

 

 

• Ribbing ntawm titanium strips hais txog kev tsis tu ncua / tsis tu ncua -zoo li tus bulges raws lub coiling kev taw qhia, muab faib raws sij hawm, thiab qhov sib nrug yog cuam tshuam los ntawm coil txoj kab uas hla thiab nro. Nyias thiab dav titanium strips feem ntau ua rau qhov tsis xws luag. Nyob rau hauv me me, lub strip nto tsis sib xws; Hauv cov xwm txheej hnyav, tawg thiab wrinkling tshwm sim, cuam tshuam rau kev ua haujlwm tom ntej.

 

• Cov nplej ntawm thaj chaw ribbing yog distorted thiab elongated, kev ntxhov siab concentration ntawm cov ciam teb nplej zoo li tsim microcracks, thiab lub hardness yog siab dua li ntawm cov matrix. Nws tsis yog ib qho zoo li flatness tsis xws luag, tab sis ib lub zos mechanical instability tshwm sim los ntawm kev nyuaj siab concentration thiab tsis sib xws yas deformation.

 

 

1. Lub strip yog raug nro, kev sib txhuam, yob deformation thiab lwm yam cuam tshuam los tsim axial compressive kev nyuaj siab, thiab lub zos bulging thiab ribbing tshwm sim thaum muaj kev ntxhov siab tshaj qhov tseem ceeb buckling kev nyuaj siab ntawm cov khoom.Thin thiab dav titanium strips yog ntau ribbing, uas yog raws li kev xyaum ntau lawm.

 

2.Qhov tseem ceeb ntawm ribbing yog cov axial quab yuam los ntawm ntau yam:

• Cov ntaub ntawv titanium muaj qhov tsis zoo deformation tsis kam, cov yob tuaj yeem ua rau deformation, ua ke nrog cov lubrication tsis zoo, tsis sib xws billet hardness thiab residual oxide txheej, ua rau lub zos deformation thiab kev sib txhuam sib txawv, tsim cov axial quab yuam.
• Kev sib zog ntau dhau ua rau axial compressive kev nyuaj siab thiab txo kev ruaj ntseg; tension fluctuation ua rau lub sij hawm hloov nyob rau hauv axial kev nyuaj siab, thiab superimposed interlayer kev sib txhuam sib txawv yooj yim ua rau ribbing. Qhov tshwm sim ntawm ribbing nyob rau hauv siab nro yog 2-3 lub sij hawm uas nyob rau hauv tsawg nro.
• Core eccentricity, strip deviation thiab uneven interlayer clearance tsim ntxiv axial quab yuam; qhov du nto ntawm titanium strips thiab qis interlayer kev sib txhuam yooj yim ua rau interlayer zawv zawg, aggravating kev ntxhov siab tsis sib xws.
• Deviations nyob rau hauv yob roundness thiab parallelism, raws li zoo raws li thav duab vibration, ua rau hloov siab thiab thickness, inducing axial quab yuam Cheebtsam; nyias- ntsuas titanium strips yog qhov nkag siab heev rau kev co, thiab kev co me ntsis yuav ua rau muaj kev ntxhov siab thiab ribbing.

 

 

• Tsawg elastic modulus ua rau loj elastic deformation nyob rau hauv tib txoj kev ntxhov siab thiab txo qis buckling kev nyuaj siab;
• Kev ua haujlwm siab ua haujlwm siab ua rau muaj kev nce nrawm ntawm deformation tsis kam thaum txias dov, yooj yim ua rau muaj kev ntxhov siab;
• Qhov tseem ceeb anisotropy ua rau muaj qhov sib txawv loj hauv cov khoom siv kho tshuab ntawm dov thiab transverse cov lus qhia, thiab tsis zoo transverse instability kuj.

 

 

1.Thin thiab dav titanium strips muaj qhov tseem ceeb buckling kev nyuaj siab thiab muaj ntau ribbing; metallurgical tsis xws luag, oxide nplai thiab khawb ntawm lub billet ua rau tsis sib xws dov deformation; titanium cov ntaub ntawv uas muaj zog yield zog thiab tsis tshua muaj elongation muaj tsis zoo plasticity, thiab kev nyuaj siab concentration yooj yim ua rau instability thiab ribbing.

 

2. Ntau dhau los yog hloov pauv ntawm lub hauv ntej thiab nram qab nro yog qhov tseem ceeb, uas yuav tsum tau tswj ntawm 30% ~ 40% ntawm lub zog tawm los; lubrication tsis zoo thiab cov txheej tsis sib xws tsim cov khoom siv axial quab yuam; ntau dhau ib zaug - dhau qhov txo qis tau yooj yim ua rau muaj kev ntxhov siab, thiab qhov tsawg dhau qhov txo qis kawg ua rau nws nyuaj rau tswj kev tiaj tus; tsis tsim nyog yob yas thiab hloov tus nqi ua rau tsis sib xws transverse siab thiab ribbing.

 

3.Tsis txaus yob roundness, parallelism thiab thav duab rigidity ua rau kev vibration thiab siab fluctuation; tsis zoo coiling concentricity, deviation kho thiab nro teb ua rau uneven nro thiab strip deviation; abnormalities nyob rau hauv lubrication system nozzles, ntws thiab pom tshwm sim nyob rau hauv lub zos lubrication tsis ua hauj lwm.

 

 

• nruj me ntsis tswj billet zoo, txo inclusions thiab segregation los ntawm composite smelting; grind lub nto ua ntej dov, thiab tswj qhov roughness ntawm Ra tsawg dua los yog sib npaug rau 0.8μm. Rau nyias -gauge cov khoom, txais yuav tuab billets, ntau dov hla dhau thiab txo ib zaug xwb- dhau deformation los txo kev ua hauj lwm hardening.
• Txais me me thiab ruaj khov nro nrog kev hloov pauv tswj ntawm ± 2%, thiab kab nyias - ntsuas coils nrog ntawv los tiv thaiv kev sib txawv; siv tshwj xeeb huab cua - siab dov roj nrog segmented siab - siab zoo lubrication; txais yuav ntau- kis me me- deformation dov nrog 6 los yog ntau dua hla, kho qhov tsis sib xws rau cov khoom siv titanium, thiab tsis txhob siv cov txheej txheem stainless hlau.
• Calibrate rolls tsis tu ncua thiab ntxiv dag zog rau tus ncej kom txo kev co; txhim kho siab -paj precision coiling, deviation kho thiab nro khoom; tswj lub lubrication system tsis tu ncua, hloov cov roj tsis tu ncua thiab kho cov kav dej thiab cov nozzles.
• Nruab cov sensors los saib xyuas qhov nro, flatness thiab vibration hauv lub sijhawm tiag tiag thiab ua haujlwm kaw -loop kho; tsim kom muaj ib tug ribbing ntxov ceeb toom qauv rau tsis siv neeg tswb thiab parameter hloov nyob rau hauv cov ntaub ntawv ntawm txawv txav; khaws tag nrho - txheej txheem tsim khoom, khoom siv thiab cov ntaub ntawv tshuaj xyuas zoo rau kev taug qab thiab kev ua kom zoo dua.
