Cov dov txias: Kub-dov steel kauj yog siv los ua cov khoom siv raw, tom qab pickling kom tshem tawm cov oxide teev, txias dov yog nqa tawm. Cov khoom tiav tiav yog nyuaj-dov kauj. Cov khaub thuas ua haujlwm tawv tawv los ntawm kev hloov pauv kom tsis tu ncua ua rau muaj zog, hnyav thiab tawv ntawm cov kauj khov. Lub plhaw yas poob qis, yog li kev ua stamping yuav ua kom tsis zoo, thiab nws tsuas yog siv rau qhov chaw ua kom yooj yim. Cov ntaub qhwv ib qho nyuaj tuaj yeem siv los ua cov khoom siv rau kub-dip galvanizing nroj tsuag vim tias txhua qhov kub-dip galvanizing chav yog nruab nrog cov kab kav hlau. Qhov hnyav ntawm dov nyuaj kauj feem ntau 6 mus rau 13.5 tons, thiab cov kauj hlau txuas ntxiv ua rau ntawm qhov kub-kuav los tiag pickled kauj nyob rau hauv chav tsev kub. Lub taub puab yog 610 hli.
Cov yam ntxwv khoom: Vim tias nws tsis tau annealed, nws lub hardness yog siab heev (HRB ntau dua 90), thiab nws cov machining kev ua haujlwm yog qhov txom nyem heev. Nws tsuas tuaj yeem ua tiav nrog cov kev taw qhia yooj yim khoov me dua li ntawm 90 qib (txiav ua ke rau cov coiling kev taw qhia).
Txhawm rau muab nws yooj yim, dov txias yog txheej txheem thiab dov ntawm lub hauv paus ntawm kub dov npuag. Feem ntau hais lus, nws yog txheej txheem ntawm kub dov --- pickling --- txias dov.
Kev ua haujlwm txias yog ua tiav los ntawm daim ntawv khoov kub ntawm chav sov. Txawm hais tias cov txheej txheem dov yuav ua kom sov daim hlau, nws tseem hu ua kev ua haujlwm txias. Vim tias cov dov kub yog dov txias tom qab kev hloov pauv txias tas li, cov cuab yeej lub zog tsis zoo thiab lub hardness dhau heev. Nws yuav tsum tau annealed los kho nws cov yam ntxwv kho tshuab, thiab cov uas tsis ua annealed hu ua dov nyuaj coils. Rolled hard coils feem ntau yog siv los ua cov khoom uas tsis tas yuav ua khoov los yog ncab.
