Dab tsi yog kub-dov, dab tsi yog txias-dov, thiab qhov txawv ntawm ob qho?

 

1. Kub dov
Cov pob zeb uas tsis tu ncua los yog cov pob zeb dov ua cov khoom siv raw, cua sov los ntawm lub cub tawg ua kauj ruam, dej siab siab dephosphorization rau hauv lub tshuab roughing, cov khoom siv roughing los ntawm kev txiav lub taub hau, tus tw, thiab tom qab ntawd mus rau hauv lub tshuab finishing, kev siv lub khoos phis tawj tswj hwm dov, dov kawg uas yog tom qab laminar flow txias (computer tswj hwm txias) thiab coiling tshuab coiling, ua cov plaub hau ncaj dov. Lub taub hau thiab tus tw ntawm cov plaub hau ncaj dov feem ntau yog tus nplaig thiab tus tw ntses zoo li, tuab, qhov dav tsis raug, feem ntau muaj ntug zoo li nthwv dej, ntug folded, pej thuam thiab lwm yam tsis zoo. Nws qhov hnyav yog hnyav, lub taub hau sab hauv ntawm cov hlau kauj yog 760 hli. (Kev lag luam ua yeeb nkab feem ntau nyiam siv.) Cov plaub hau ncaj dov los ntawm kev txiav lub taub hau, tus tw, txiav ntug thiab ntau dua ib qho ncaj, leveling thiab lwm yam kev ua tiav kab, thiab tom qab ntawd txiav phaj lossis rov dov, uas yog: hlau kub dov phaj, hlau kub dov tiaj tus, txiav kab ntev thiab lwm yam khoom. Cov hlau kub dov tiav yog tias pickling kom tshem tawm cov tawv nqaij oxide thiab roj rau hauv kub dov pickled kauj. Daim duab hauv qab no qhia txogkub dov kauj.

 

2. Txias dov
Cov hlau dov kub ua cov khoom siv raw, tom qab pickling kom tshem tawm cov tawv oxide rau kev dov txias, cov khoom tiav rau cov khoom dov tawv, vim tias qhov txias tas li deformation tshwm sim los ntawm kev txias hardening ntawm cov hlau dov tawv ntim ntawm lub zog, hardness, toughness thiab cov ntsuas yas poob qis, stamping kev ua tau zoo poob qis, tsuas yog siv rau kev hloov pauv yooj yim ntawm cov khoom. Cov hlau dov tawv tuaj yeem siv ua cov khoom siv raw rau cov nroj tsuag kub-dip galvanizing, vim tias chav tsev kub-dip galvanizing tau teeb tsa nrog kab annealing. Cov hlau dov tawv hnyav feem ntau yog 6 ~ 13.5 tons, sab hauv txoj kab uas hla ntawm lub kauj yog 610 hli. Feem ntau cov phaj txias dov, kauj yuav tsum tau txuas ntxiv annealing (CAPL unit) lossis hooded cua sov de-annealing kev kho mob, kom tshem tawm cov khoom siv kho tshuab thiab dov kev ntxhov siab, kom ua tiav cov khoom siv kho tshuab teev nyob rau hauv cov ntsuas tus qauv. Cov hlau dov txias phaj qhov zoo ntawm qhov chaw, tsos, qhov tseeb ntawm qhov ntev zoo dua li cov phaj kub dov. Daim duab hauv qab no qhia txogtxias dov kauj.

 

Qhov txawv tseem ceeb ntawmhlau dov txias vs hlau dov kubnyob rau hauv cov txheej txheem ua, qhov ntau thiab tsawg ntawm daim ntawv thov, cov khoom siv kho tshuab thiab qhov zoo ntawm qhov chaw, nrog rau qhov sib txawv ntawm tus nqi. Cov hauv qab no yog cov lus qhia ntxaws ntxaws:
Kev Ua. Kev dov kub yog ua tiav ntawm qhov kub siab, thaum kev dov txias yog ua tiav ntawm qhov kub hauv chav. Kev dov kub yog dov siab dua qhov kub ntawm crystallization, thaum kev dov txias yog dov qis dua qhov kub ntawm crystallization.

 
Daim Ntawv Thov. Cov hlau kub dov feem ntau yog siv rau hauv cov qauv hlau lossis cov khoom siv kho tshuab, suav nrog kev tsim kho choj, thaum cov hlau txias dov feem ntau siv rau hauv kev lag luam tsheb lossis cov khoom siv me me, tshuab ntxhua khaub ncaws, tub yees, thiab lwm yam, suav nrog cov ntaub ntawv tsim kho.

 
Cov khoom siv kho tshuab. Cov khoom siv kho tshuab ntawm cov ntawv dov txias feem ntau zoo dua li cov ntawv dov kub, vim tias cov txheej txheem dov txias ua rau muaj qhov tawv lossis tawv txias, ua rau daim ntawv dov txias qhov nyuaj thiab lub zog siab dua, tab sis qhov tawv qis dua, thaum cov khoom siv kho tshuab ntawm cov ntawv dov kub tsawg dua li cov ntawv dov txias, tab sis muaj qhov tawv thiab ductility zoo dua.

 
Qhov zoo ntawm qhov chaw. Qhov zoo ntawm cov qauv nto ntawm cov hlau txias dov yuav zoo dua li cov hlau kub dov, cov khoom txias dov yog qhov nyuaj dua thiab tsis yooj yim ductile, thaum cov khoom kub dov muaj qhov chaw ntxhib dua, muaj cov qauv.

 
Cov lus qhia tuab. Cov kauj txias feem ntau nyias dua li cov kauj kub, nrog rau qhov tuab ntawm cov kauj txias ntau ntawm 0.3 txog 3.5 millimeters, thaum cov kauj kub ntau ntawm 1.2 txog 25.4 millimeters.

Nqe: Feem ntau, cov hlau dov txias kim dua li cov hlau dov kub. Qhov no yog vim tias cov hlau dov txias xav tau kev siv cov khoom siv ua haujlwm zoo dua thiab cov txheej txheem txheej txheem nyuaj dua, thiab kev kho cov hlau dov txias tuaj yeem tau txais cov txiaj ntsig zoo dua, yog li qhov zoo ntawm cov khoom dov txias feem ntau siab dua, tus nqi kuj siab dua. Tsis tas li ntawd, cov hlau dov txias hauv cov txheej txheem ntau lawm xav tau cov txheej txheem ua haujlwm nruj dua thiab qhov nyuaj ua haujlwm siab dua, cov khoom siv tsim khoom, yob thiab lwm yam khoom siv xav tau siab dua, uas tseem yuav ua rau cov nqi tsim khoom nce ntxiv.
