Qhov sib txawv ntawm hot rolled steel strip thiab cold rolled steel strip

(1) qhob hlau hnub no tshav hlau yog li qhob hlau hnyav muaj kev phom sij, tsawg tshaj qhob hlau hnyav, tab sis tuaj yeem ua rau muaj kev nyuaj siab zoo dua, siv rau qhob hlau hnub no tshav hlau thiab lwm yam khoom.

(2) qhob hlau hnub no tshav hlau siv qhob hlau hnub no tshav hlau uas tsis muaj qhob hlau hnyav, zoo li qhob hlau hnub no tshav hlau. Qhob hlau hnyav siv qhob hlau hnyav muaj qhob hlau hnyav, qhob hlau hnyav muaj qhob hlau hnyav.

(3) qhob hlau hnyav muaj kev nyuaj siab thiab kev zoo ntawm qhob hlau hnyav zoo li qhob hlau hnub no tshav hlau, ntau dua, tab sis qhob hlau hnub no tshav hlau zoo dua, kev nyuaj siab zoo dua, tab sis ntau dua.

(4) qhob hlau hnyav thiab qhob hlau hnub no tshav hlau txawv txawv, qhob hlau hnyav thiab qhob hlau hnub no tshav hlau txawv txawv nrog kev txiav txim siab.

(5) Qeev ntoo: qeev ntoo feem ntau siv rau hauj lwm tsim cov ntoo hlav, nws lub zog qeev siab dua. Ntoo hlav ua los ntawm kev ua rau sov: txoj sov ntawm kev ua rau sov zoo li ntawd li qhov sov ntawm kev tsim tawj.

(6) Lub ntim ntawm hot rolled steel plate uas tsis muaj plating yuav ua rau nws hliv ntau, lub ntim ntawm cold rolled steel plate uas tsis muaj plating yog gray, thaum plating lawm, peb tuaj yeem sib piv los ntawm lub smoothness ntawm lub ntim, uas siab dua li hot rolled steel plate.

Hot-rolled strip lub dav ntawm nws tsawg tshaj los yog tib yam li 600mm, lub thickness yog 0.35-200mm rau lub steel plate thiab 1.2-25mm rau lub steel strip.

Hot Rolled Strip Tus kheej nyob rau hauv lub suav thiab lub tsev ua hauj lwm los ntawm kev hloov kho

Kev txi rau cov kab rov roj ua ntej los yog ib qho ntawm cov ntaub ntawv ua rau cov roj ua ntej, siv dav hauv kev lag luam, tiv thaiv, kev lag luam thiab kev tsim kho, thiab ua raw material rau kev tsim kho cov roj ua ntej, cov kab roj ua ntej, thiab lwm yam. cov khoom tsim tawm hauv Suav teb hauv ib xyoos tseem ceeb heev hauv kev tsim kho cov roj ua ntej.

Hauv cov teb chay uas muaj kev lag luam pib, cov roj ua ntej thiab cov kab roj ua ntej tau txiav txiis txog 80% ntawm qhov tseeb ntawm cov roj thiab cov kab roj ua ntej, txiav txiis ntau tshaj 50% ntawm qhov tseeb ntawm kev tsim kho roj, thiab nyob rau hauv qhov kev lag luam hauv ntau lub teb chay.

Nyob rau hauv Suav teb, cov khoom roj ua ntej feem ntau, qhov tsawg kawg ntawm qhov hnyav yog 1.8mm, tab sis nyob rau hauv qhov tseeb, feem ntau tsawg heev cov kws tsim khoom tsim cov kab roj ua ntej uas muaj qhov hnyav tsawg dua 2.0mm, txawm tias cov kab roj ua ntej, qhov hnyav ntawm cov khoom feem ntau dav dua 2.5mm.

Ntawd li, qhov siab uas yuav siv cov duab nrog qhov hnyav tsawg dua 2mm raws li cov khoom siv, cov neeg siv khoom tseem yuav tsum siv cov duab uas tsis tau txiav.

Cold Rolled Strip

Cold rolled steel strip: metal nyob rau saum ntawm qhov kub uas tuaj yeem hloov kho, qhov rolling deformation uas tsis tau txiav, feem ntau sau tseg tias cov duab tsis tau txiav thiab tsis muaj kub ntau, siv cov duab hloov kho nyob rau hauv av. Cold rolled strip tuaj yeem muaj kub, tab sis nws tseem hu ua cold rolled.

Cold rolled production tuaj yeem cia cov neeg siv cov khoom ua haujlwm zoo thiab muaj peev xwm zoo, qhov tseem ceeb tshaj plaws yog qhov kub hnyav hnyav, hn compared with the hot rolling production, nws muaj cov qhia zoo no:

(1) Cov khoom siv Cold rolled strip muaj qhov ntev zoo thiab qhov hnyav zoo ib yam, qhov sib txawv ntawm qhov hnyav ntawm cov duab feem ntau tsis txawv ntau dua 0.01-0.03mm lossis tsawg dua, uas tuaj yeem tiv thaiv cov kev cai zoo.

(2) Qhov zoo tshaj plaws uas tsis tuaj yeem tsim los ntawm kev hlauv hlau los ntawm kev hlauv ntau dua li tuaj yeem txais (qhov zoo tshaj plaws tuaj yeem txog 0.001mm lossis lwm qhov zoo dua).

(3) Qhov chaw nruab nrab ntawm cov khoom hlauv nrog hluav taws nrog kev hlauv zoo li qhov chaw nruab nrab ntawm cov hlauv hlau uas tsaus pom qhov chaw nqus, qhov chaw hlauv hlau hlau, thiab lwm yam, thiab tuaj yeem tsim raws li kev xav tau ntawm tus neeg siv hluav taws nrog qhov chaw nruab nrab (qhuav siab lossis qhov chaw nqus, thiab lwm yam), kom ua haujlwm rau qhov kev ua haujlwm tom ntej.

(4) Cov hlauv hlauv zoo muaj qhov zoo tshaj plaws hauv kev ua haujlwm thiab kev ua haujlwm (xws li qhov siab dua, qhov siab tawg zoo dua, kev ua haujlwm zoo dua, thiab lwm yam).

(5) Tus neeg hlauv zoo thiab kev hlauv zoo tuaj yeem ua tiav, nrog qhov siab.

Qeeb ntawm hlauv hlauv zoo

Txheej hlau ua los ntawm qhov txiav ntawm txheej hlau hnyav muaj ob hom: daj laug thiab hlau hlub.

(1) kab xov hlau uas poob hluav taws: xov hlau uas poob ntxiv rau lub tsev hluav taws, lub kaum ntse ntsev rau lub hauv paus hluav taws, lub ntsiab lus hlau ua rau lub kaum ntsev hluav taws los ntawm kev sib txuas nrog hau, kab xov hlau yuav poob hluav taws. Lub zog hluav taws yuav ua rau kab xov hlau yuav ntxim, feem ntau siv rau kab xov hlau thiab tom qab ntawd ua rau nws hla, nqus, thiab ua kom huv dua.

(2) kab xov hlau uas tsim kev nyab xeeb: thiab kab xov hlau uas poob hluav taws qhia tias qhov sib txawv loj tshaj plaws yog tias qhov kev hluav taws tsis sib txuas nrog hau, siv nitrogen thiab lwm yam hau tiv thaiv, lub ntsiab lus hlau ua rau kab xov hlau zoo li kab xov hlau uas poob ntxiv, tseem siv rau lub ntsiab lus hlau thiab nickel thiab lwm yam kev txhim kho kab xov hlau, zoo thiab tsim nyab xeeb.

Qhov sib txawv ntawm kab xov hlau uas tsim kev nyab xeeb thiab kab xov hlau uas poob hluav taws: lub zog hluav taws zoo li tib yam, kab xov hlau uas tsim kev nyab xeeb yog kab xov hlau uas poob hluav taws uas tau txhoo rau ib qhov kawg tshiab.

Kev siv: cov roj hlau hlav uag muaj peb yam hlau ua rau cov khoom lag luam ua ntej los ua kev lag luam, cov hlau hlav zoo li ntawd tuaj yeem tsim cov khoom lag luam.

Ntsiab lus txog kev hloov kho hlau hlav sov tshav tshos

Cov lus txib txab hloov kho hlau hlav sov tshav tshos yog qhov tseem ceeb ntawm qhov chaw ua hlau. Cov hlau hlav zoo li ntawd siv rau kev ua tshuab ntoo, kev ua tshuab ntau, kev lag luam, kev ua khob ntsu, ua tsev, thiab lwm yam kev lag luam, thiab kuj muaj kev sib txuas nrog kev nyob hauv vaj tse, xws li cov khoom tiv thaiv ntawv, cov khoom ua siab, cov khoom tiv taus thiab lwm yam. Vim li no, hauv qee qhov teb chaws uas muaj kev pab cuam kev lag luam, cov hlau hlav zoo li ntawd tau txiav txim ntau dhau los ntawm qhov ntau ntawm hlau, hauv cov hlau hlav, cov hlau hlav sov tshav tshos tau txiav txim ntau.
