GL Marine Steel Phaj Qib EH36

Nov yog qee txoj hauv kev los ua kom qhov nyuaj ntawm GL (Germanischer Lloyd) shipbuilding steel phaj qib EH36:

 

I. Txoj kev kho cua sov

 

Quenching:

Tshav kub EH36 steel rau qhov kub thiab txias (feem ntau ntawm 850 degree - 950 degree) kom ua tiav nws cov qauv.

Tom qab ntawd maj mam muab tso rau hauv qhov chaw txias (xws li dej, roj, thiab lwm yam) kom txias sai. Qhov no yuav hloov cov hlau cov qauv rau hauv martensite, uas muaj siab hardness thiab lub zog. quenching tuaj yeem ua rau qhov nyuaj ntawm EH36 steel, tab sis tib lub sijhawm, nws kuj tseem tuaj yeem ua rau cov hlau nkig, yog li kev kho tempering tom ntej yog xav tau los txo qhov brittleness.

Piv txwv li, hauv qee qhov kev lag luam tshwj xeeb, qhov nyuaj ntawm EH36 steel tom qab quenching tuaj yeem nce los ntawm 200HBW (Brinell hardness) mus rau ntau tshaj 400HBW.

Tempering:

Ua tempering kho tom qab quenching. Ntawd yog, ua kom sov cov hlau kom qis dua (feem ntau ntawm 500 degree - 650 degree), thiab tom qab ntawd txias nws tom qab tswj xyuas rau qee lub sijhawm. Tempering tuaj yeem txo qhov brittleness ntawm quenched steel thiab tib lub sij hawm txhim kho nws cov toughness thiab plasticity. Rau qee qhov, tempering kuj tuaj yeem kho qhov hardness ntawm cov hlau kom ncav cuag qhov xav tau hardness ntau yam.

Piv txwv li, yog tias nws yuav tsum tau kho qhov hardness ntawm EH36 steel rau 300 - 350HBW, qhov kub thiab txias thiab lub sijhawm tuaj yeem raug xaiv rau kev kho mob.

 

II. Cov txheej txheem ua haujlwm txias

 

Txias Rolling:

Ua kom txias dov rau ntawm EH36 steel, uas yog, ua kom cov hlau dhau los ntawm cov yob rau compression deformation ntawm chav tsev kub. Txias dov tuaj yeem kho cov nplej ntawm cov hlau thiab ua kom cov qauv ua kom zoo dua qub, yog li ua kom lub zog ntawm cov hlau.

Txawm li cas los xij, txias dov yuav txo cov plasticity ntawm cov hlau. Yog li ntawd, nws yog ib qho tsim nyog los tswj cov deformation tus nqi ntawm txias dov kom tsis txhob over hardening ntawm cov hlau thiab ua rau tawg thiab lwm yam teeb meem.

Piv txwv li, qhov nyuaj ntawm EH36 steel tom qab kev kho mob khaub thuas uas tsim nyog tuaj yeem nce los ntawm 20 - 50HBW.

Txias daim duab:

Kev kos duab txias yog txhawm rau ncab cov hlau los ntawm kev tuag kom txo tau txoj kab uas hla thiab nce qhov ntev ntawm cov hlau. Kev kos duab txias tuaj yeem ua kom zoo dua cov nplej ntawm cov hlau thiab txhim kho hardness thiab lub zog ntawm cov hlau.

Zoo ib yam li txias dov, kos duab txias kuj yuav tsum tau tswj cov deformation tus nqi kom tsis txhob muaj qhov tsis xws luag hauv cov hlau.

Piv txwv li, qhov nyuaj ntawm EH36 steel tom qab txias txias tuaj yeem nce los ntawm 30 - 60HBW.

III. Alloying txoj kev

 

Ntxiv carbon element:

Ua kom cov pa roj carbon ntsiab lus hauv EH36 steel tuaj yeem ua rau cov hlau tsis muaj zog. Cov pa roj carbon tuaj yeem tsim cov hlau hnyav thiab nkig carbide (Fe3C) nrog hlau, yog li ua rau cov hlau hnyav dua. Txawm li cas los xij, cov ntsiab lus carbon ntau dhau yuav txo qhov toughness thiab weldability ntawm cov hlau, yog li cov ntsiab lus carbon yuav tsum tau tswj nyob rau hauv ib qho chaw.

Piv txwv li, nce cov ntsiab lus carbon ntawm EH36 steel los ntawm kwv yees li 0.18% mus rau li ntawm 0.25% tuaj yeem ua rau cov hlau hnyav nce li ntawm 30 - 50HBW.

Ntxiv alloying ntsiab:

Ntxiv qee cov ntsiab lus alloying xws li manganese (Mn), chromium (Cr), molybdenum (Mo), npib tsib xee (Ni), thiab lwm yam rau EH36 steel tuaj yeem ua kom cov tawv tawv thiab lub zog ntawm cov hlau. Cov ntsiab lus alloying no tuaj yeem tsim cov kev daws teeb meem los yog carbides los txhim kho lub lattice lub zog ntawm cov hlau thiab yog li ua kom lub zog ntawm cov hlau.

Piv txwv li, ntxiv qhov tsim nyog ntawm manganese tuaj yeem nce hardness ntawm EH36 steel los ntawm 20 - 40HBW; ntxiv chromium thiab molybdenum tuaj yeem ua rau cov hlau hardness nce li ntawm 40 - 80HBW.
