Qhov txawv ntawm Gelat thiab khaub thuas Zahang

Wuxi Puxin Machinery Factory | Updated: May 24, 2017

Kub dov thiab txias zaws raws li qhov nrov tshaj plaws nyob rau hauv kev ua lag luam ob hom kev ua hlau ua, los ntawm cov xov tooj ntawm cov tshuab ua lag luam loj, siv ob lub tshuab ua cav hlau thaum kawg qhov txawv yog dab tsi?
I. Txias khaub thuas
Mob khaub thuas dov yog xa mus rau qhov txias txias, Leng, txias, thiab lwm yam nyob rau hauv chav tsev kub, hlau los yog hlau sawb ua rau ntau hom duab, kev lag luam yog nrov heev txias kos ca hlau, txias drawn flat steel manufacturers kuj ntau .
Kev Zoo: Cov thawv txias tuaj yeem ua rau cov khoom siv ceev ceev, cov zis siab, thiab cov txheej txheem yuav tsis ua kom puas txheej, tuaj yeem ua ntau yam hauv daim ntawv, kom siv tau rau kev siv lub sijhawm; txias-rolled steel tau tsim ib lub cev loj deformation, uas yog kev txhim kho cov kis ntawm cov hlau.
Disadvantage: Txawm hais tias tsis muaj thermal plasticity nyob rau hauv txoj kev molding, tab sis residual stress yog tseem nyob rau hauv seem, qhov no yuav cuam tshuam rau tag nrho thiab hauv zos buckling ntawm hlau. Cov phom duav no feem ntau yog qhib seem, kom lub torsion ntawm qhov seem tsis tshua muaj, thaum tus quab yuam sab nraud yog torsion, thiab nyob hauv siab yuav ua rau nws khoov buckling, cov hlau nws tus kheej yog plam torsional kev ua tau zoo; Tom qab qhov txias-rolled hlau yog tsim, tsis muaj thickening nyob rau hauv lub sib koom tes ntawm lub phaj, thiaj li lub siab kam rau ntawm lub hlau yog pluag.
II. Kub dov
Zoo: Cov hlau yuav ua puas tsuaj, qhov kho raws ntawm microstructure yog tshem tawm, lub microstructure ntawm cov hlau yog compacted, thiab cov khoom kho vaj tse zoo tuaj. Hom kev txhim kho no tsuas yog tshwm sim ua raws li kev txiav txim siab, cov hlau hauv qee degree yuav tsis yog txhua tus tib lub cev. Cov kab nrib pleb thiab npuas tsim thaum lub sij hawm rov qab yog raug tshem tawm ntawm high temperatures.
Kev tsis zoo: Tom qab kub dov, hlau nrog cov thawv uas tsis yog xim hlau yuav tsum muab tso rau hauv nyias lub khoob khoob, ua rau tshwm sim ntawm delamination, delamination yuav ua rau cov hlau ntub dej thaum lub qhov ntswg tshwm sim; qhov kev ntxhov siab no yog tshwm sim los ntawm qhov tsis sib txig, uas ua rau lub suab deev, ua rau kom ruaj khov, thiab txo qis qaug zog hauv qee qhov kev kawm.
Thib peb, qhov kub thiab txias tshaj plaws:
(1) Cov nplais hlau ntawm cov thawv txias tuaj yeem pub rau cov neeg hauv zos, uas tuaj yeem ua rau kev siv puv npo ntawm qhov buckling;
(2) Qhov kev ntxhov siab ntawm cov pob zeb kub kub thiab txias La Chang ntawm cov hlau yog txawv, thiaj li muaj qhov sib txawv hauv qhov faib ntawm ntu. Qhov kev ntxhov siab ntawm kev sib tw txias yog qhov tsuas yog curved hom, thiab kub rolling yog hom yeeb yam.
(3) Lub torsion ntawm lub tsho uas muaj hlau tawg yog qhov siab tshaj qhov uas cov cua txias sib tw, yog li torsional kev ua haujlwm ntawm cov pob zeb kub kub yog qhov zoo tshaj qhov uas muaj cov cua txias.
