Txias dov nyob rau hauv recrystallization kub hauv qab no hu ua txias-dov, kub dov kauj raws li raw khoom, feem ntau yog siv nyob rau hauv cov kua qaub pickling kom tshem tawm oxide ntawm daim tawv nqaij tom qab txias dov, cov khoom tiav yog ib qho nyuaj, vim hais tias ntawm txias ua hauj lwm hardening tshwm sim los ntawm deformation ntawm nruam. txias dov tawv yob lub zog, nce hardness, toughness thiab yas Performance index txo, yog li cov stamping kev kawm yuav deteriorate, tsuas yog siv tau yooj yim deformation ntawm qhov chaw.
Hard coil tuaj yeem siv los ua cov khoom siv raw, kub dip galvanized Hoobkas rau kub dip galvanizing chav tsev Chaw yog annealed hlau.
Hard ntim hnyav hauv 20 - feem ntau
40 tons, steel kauj, nyob rau hauv chav tsev kub rau nruam dov ntawm kub dov pickling ntim.
Cov khoom siv txias txias: vim tias tsis muaj kev kho mob tom qab annealing, hardness siab heev (
HRB ntau dua 90)
, mechanical processing performance yog pluag, tsuas yog yooj yim muaj directivity yog tsawg tshaj li 90 degree khoov ua.
Yooj yim, txias-dov, yog nyob rau hauv lub hauv paus ntawm kub-dov coil ua dov tawm, feem ntau yog kub dov -

Txias dov cov txheej txheem ua.
Txias dov yog nyob rau hauv cov xwm txheej ntawm kev ua tiav los ntawm kub dov phaj, thaum nyob rau hauv cov txheej txheem ntawm machining rau dov yuav ua rau steel phaj kub, txawm li cas los xij hu ua txias dov.
Vim hais tias ntawm qhov kub dov los ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov txias txias hauv cov tshuab ua haujlwm tsis zoo, hardness siab dhau lawm, yog li yuav tsum dhau los ntawm annealing los kho nws cov khoom siv kho tshuab, tsis muaj annealing nyuaj.
Hard coil feem ntau yog siv los ua tsis muaj dabtsi yog khoov, ncab khoom, 1.
Hauv qab xoom tuab ntawm ob sab ntawm txoj hmoov zoo los yog quadrilateral dabtsi yog khoov.
Txias dov feem ntau tom qab kho annealing.
Yuav tsum tau siv nyob rau hauv cov txheej txheem ntawm txias dov txias dov roj, cov txiaj ntsig ntawm kev siv cov roj dov txias yog: 1, txo cov kev sib txhuam coefficient, muab cov kev sib tw dov, dov qis zog noj, txaus siab dov tsis;
2, ua kom lub ntsej muag ci ntsa iab thiab tuab tuab ntawm dov qeeb;
3, cov nyhuv txias zoo, tuaj yeem tshem tawm qhov kub dov, tiv thaiv yob thiab dov daim.
Annealing kev ua tau zoo, yuav tsis tsim cov roj hlawv tshwm sim;
4, muaj lub sij hawm luv luv los tiv thaiv xeb, tuaj yeem muab kev tiv thaiv xeb ib ntus ntawm cov khoom dov.
Kub dov kub dov (
热轧)
belongs rau kub ua hauj lwm ntawm dov txheej txheem.
Kub dov high efficiency efficiency, loj scale, tsawg zog noj, tsis muaj nqi, high degree ntawm mechanization, automation, haum rau huab hwm coj ntau lawm kab, yog ib tug ntawm cov tseem ceeb tshaj plaws hlau siab ua txoj kev.
Kub dov los ntawm kev ua cov hlau deformation kuj yog tsawg thiab cov yas thiab dav siv.
Tab sis txij li thaum lub dov daim kub tsis yooj yim rau tusyees thaum dov, tin oxide nto muaj nyob, cov khoom loj qhov tseeb thiab nto roughness yog tsawg dua cov khoom txias.
Yog cov khoom siv tseem ceeb rau kub dov zeb.
Siv nyob rau hauv kub dov zeb yog ntau ntau phyletic, muaj ob yob zeb, peb yob zeb, yob zeb ntawm slaughter, plaub siab dov zeb, Y hom dov zeb, ob-siab skew dov zeb, peb-yob skew dov zeb , hla dov zeb, universal zeb thiab txhua yam tshwj xeeb zeb thiab lwm yam.
Raws li qhov yuav tsum tau ua ntawm ntau yam ntawm cov khoom, cov khoom zoo, ntau lawm, qhov chaw nyob, thiab lwm yam, muaj ntau hom dov zeb ntawm kub dov rhiav layout, xws li ib lub tshuab layout, ib qho los yog ntau kab ntawm qhib-tsheb ciav hlau kev npaj, taug qab txoj kev npaj, dov hom layout, chessboard hom yog dai kom zoo nkauj, thiab lwm yam.
Cov txheej txheem kub dov ntau lawm feem ntau suav nrog kev npaj cov khoom siv raw, cua sov, dov, xov thiab lwm yam ntawm ntau cov txheej txheem loj.
Kub dov tuaj yeem siv rau dov steel ingot lossis loj billet, tsim cov khoom loj loj.
Zoo li lub ingot loj rau dov 70 t nyob rau hauv thiab ib ncig ntawm 50 t loj billet, tsim lub thickness ntawm 500 hli tuab phaj, seamless steel yeeb nkab ntawm 1070 hli inch, 1200 mm x 530 MMH steel thiab 78 kg / m rails, thiab lwm yam.
Nyob rau hauv cov txheej txheem kub dov, dov daim kub maj mam txo, cov khoom deformation kuj nce maj mam, nws thiaj li tsis tuaj yeem ua qhov chaw kub.
Yog li nws tsis yog qhov loj ntawm cov khoom kub dov tej zaum yuav me me, tsuas yog 1 hli tuab daim ntawv dov, 20 hli txoj kab uas hla seamless steel yeeb nkab, txoj kab uas hla ntawm 5.
0mm cev.
Kab.
Yog li nws tsis yog qhov loj ntawm cov khoom kub dov tej zaum yuav me me, tsuas yog 1 hli tuab daim ntawv dov, 20 hli txoj kab uas hla seamless steel yeeb nkab, txoj kab uas hla ntawm 5.
0mm cev.
Kub dov muaj peev xwm muaj peev xwm ntau lawm, txhua xyoo tso zis ntawm 6 lab t ntawm ntxhib dov zeb, yog tias muaj, muaj peev xwm txhua xyoo ntawm 6 lab t kub dov DaiGangChang thiab lwm yam.
Cov khoom kub dov tuaj yeem muab faib ua ntu ntu cov yam ntxwv ntawm cov khoom kub dov, kub dov seamless steel yeeb nkab, kub dov steel thiab tshwj xeeb steel kub dov plaub chav kawm.
Kub dov los ntawm dov txoj kev yog tsuas yog muab faib ua longitudinal dov, skew dov thiab dov.
Qhov sib txawv ntawm qhov txias dov thiab kub dov, txias dov mus rau hauv ntu 1 kom tso cai rau hauv zos buckling seem, uas tuaj yeem ua rau tag nrho kev siv lub bar buckling bearing muaj peev xwm tom qab;
Hauv zos buckling thiab kub dov hlau tsis pub hla ntu.
2, qhov ua rau kub dov hlau thiab txias dov steel residual kev nyuaj siab yog txawv, yog li kev faib ntawm hla ntu kuj muaj qhov sib txawv loj heev.
Cold-formed nyias-walled steel hla ntu ntawm qhov seem ntawm kev ntxhov siab yog nkhaus, thiab kub dov steel lossis welded steel residual kev ntxhov siab faib rau ntawm ntu ntu yog nyias zaj duab xis.
3, kub dov hlau tsis muaj torsional rigidity yog siab dua txias dov hlau, yog li lub torsion zog ntawm kub dov hlau yog zoo dua li txias dov hlau.
