Ipleyiti yentsimbi eshushu eqengqiwe

inzuzo

Intsimbi eshushu eqengqelekayo inobulukhuni obuphantsi, ukusetyenzwa lula kunye ne-ductility elungileyo.

Ipleyiti yentsimbi eshushu eqengqelekayo, iipropathi zoomatshini zingaphantsi kakhulu ekusebenzeni okubandayo, kwaye zingaphantsi kubunjwa, kodwa zinobulukhuni obungcono kunye nokuqina.

Umahluko phakathi hot rolled steel stainless kunyekubanda kuqengqeleka

Umahluko phakathi kwe-hot rolling kunye ne-cold rolling yensimbi engenasici kukuba i-cold rolling iqengqeleka ngesiseko se-hot rolling.

I-Cold rolling: Icutshungulwa kwaye igqitywe ngesiseko se-hot-rolled stainless steel plate kunye ne-coil.Xa sithetha gabalala, yinkqubo yokuqhuba ukuqengqeleka okushushu → ukuchola → ukuqengqeleka okubandayo.Nangona ipleyiti yentsimbi iya kufudumala ngenxa yokuqengqeleka ngexesha lokucutshungulwa, isabizwa ngokuba yi-cold rolling.Ngenxa ye-deformation eqhubekayo ebandayo ye-hot rolling, iipropati ze-mechanical zincinci kwaye ukuqina kuphezulu kakhulu.Kufuneka ifakwe i-anneal ukubuyisela iimpawu zayo zoomatshini, kwaye ezo zingenayo i-annealing zibizwa ngokuba ziikhoyili eziqinileyo.Iikhoyili eziqinileyo zisetyenziselwa ukwenza iimveliso ezingadingi ukugoba okanye ukunweba.

Iimpawu zayo:

1. Ngenxa yeqondo elithile lomsebenzi wokuqina, amashiti ensimbi apholileyo anobunzima obuphantsi kwaye abiza kakhulu;

2. Indawo epholileyo epholileyo ayinayo isikali se-oxide, kwaye umgangatho ulungile;

3. Imveliso eyenziwe yi-deformation ebandayo inokuchaneka okuphezulu kunye nomgangatho omhle womphezulu;

4. I-Cold rolling isetyenziswa ngokubanzi kuzo zonke iinkalo zobomi ngenxa yenkqubo yayo yokuvelisa, njengazo zonke iintlobo zamacandelo abandayo, iiprofayili ze-extrusion ezibandayo ezibandayo, imithombo ye-coil ebandayo, iingcingo ezibanjwa ngokubanda, iibholiti ezibandayo, njl.

I-Hot rolling (i-hot rolling): ngokumalunga nokuqengqeleka okubandayo, ukuqengqeleka okubandayo kuqengqeleka ngaphantsi kweqondo lobushushu le-recrystallization, kwaye ukuqengqeleka okushushu kuqengqeleka ngaphezulu kobushushu bokuhlaziya.

Iimpawu zayo:

1. Ukuqina kunye nokuthe tyaba komphezulu kubi, kwaye ixabiso liphantsi;

2. Iqondo lobushushu le-hot rolling lifana nelo lokubumba;

3. Iipleyiti eshushuishushu iqengqeleke kwaye inesikhumba se-oxide phezu komhlaba, kwaye ubukhulu beplate buhlukile;

4. Ngenxa yenkqubo yokuvelisa, isetyenziswa kwizicelo ezininzi zabantu, njengempahla yasekhitshini, izixhobo zasekhaya eziqhelekileyo, njl.njl.;

5. Iimpawu zoomatshini zeamashiti entsimbi ashushuzingaphantsi kakhulu kwezo zokusebenza ezibandayo kunye ne-forging, kodwa zinobulukhuni obungcono kunye ne-ductility.
