Lub hom phiaj tseem ceeb ntawm kev cai - ua cua sov - kev kho mob yog raws li nram no:

 

Optimize Mechanical Properties

 

Ua kom muaj zog: Cov txheej txheem xws li quenching tuaj yeem txhim kho lub zog ntawm cov hlau. Piv txwv li, quenching enables steel los tsim ib tug martensitic qauv, uas muaj kuj siab hardness thiab lub zog. Hauv kev siv tshuab - kev lag luam kev lag luam, rau cov khoom uas nqa cov khoom hnyav (xws li cranes thiab kev tsim kho - cov khoom siv tshuab), kev sib xyaw ua ke ntawm quenching thiab tempering txheej txheem tuaj yeem siv. Lub quenching kub yog los ntawm 910 degree mus rau 940 degree, nrog roj quenching, thiab tempering kub yog los ntawm 580 degree mus rau 630 degree, nrog ib tug tuav lub sij hawm ntawm 2 - 3 teev tom qab cua - txias. Qhov no tuaj yeem txhim kho lub zog ntawm cov hlau, ua kom nws tiv taus siab dua thiab tensile rog.

 

Txhim kho Toughness: Normalizing thiab tempering txheej txheem yuav pab tau rau kev txhim kho lub toughness ntawm steel. Nyob rau hauv lub shipbuilding thiab marine - engineering teb, rau lub Cheebtsam nrog complex cov duab uas yuav tsum tau microstructure thiab cov cuab yeej txhim kho tom qab vuam (xws li lub bulkhead lugs ntawm lub nkoj), normalizing kev kho mob (qhov normalizing kub yog los ntawm 920 degree mus rau 960 degree, thiab cua - txias. tom qab tuav) tuaj yeem kho cov nplej thiab tshem tawm cov kev ntxhov siab welding, yog li txhim kho qhov toughness thiab qaug zog ntawm cov khoom. Kev txhim kho toughness ua rau cov khoom tsis tshua muaj kev tawg thaum raug cuam tshuam los yog dynamic loads, ua kom muaj kev ruaj ntseg thiab kev ntseeg siab ntawm cov khoom.

 

 

 

Txhim kho Machining Properties

 

Txo Hardness kom yooj yim Machining: Nyob rau hauv kev tsim kho kev lag luam, yog CCS A420 steel siv rau loj-scale steel structural Cheebtsam (xws li txuas hniav thiab siab - nce tsev kab thiab kab teeb), annealing kev kho mob (lub annealing kub feem ntau yog los ntawm 780 degree mus rau 820 degree , nrog rau ib tug kev kho mob. tuav lub sij hawm ntawm 3 - 4 teev, thiab maj mam txias nyob rau hauv lub cub tawg rau hauv chav tsev kub) tuaj yeem nqa tawm ua ntej machining. Qhov no tuaj yeem txo qhov hardness ntawm cov hlau, yog li txhim kho kev ua haujlwm ntawm machining thiab ua kom yooj yim rau kev txiav, laum, thiab lwm yam thaum lub sijhawm machining txheej txheem.

 

Tshem tawm Internal Stress kom txo tau deformation txaus ntshai: Ob qho tib si annealing thiab normalizing cov txheej txheem tuaj yeem tshem tawm cov kev ntxhov siab sab hauv ntawm cov hlau mus rau qee yam. Hauv kev tsim kho kev lag luam, tom qab ua tiav (xws li vuam thiab forging), hlau yuav tsim kev ntxhov siab sab hauv, uas yuav ua rau deformation thaum siv tom ntej. Los ntawm cov txheej txheem kev kho cua sov uas tsim nyog (xws li saum toj no - hais annealing lossis normalizing), cov kev ntxhov siab sab hauv tuaj yeem raug tshem tawm, qhov kev pheej hmoo deformation tuaj yeem txo qis, thiab qhov ruaj khov ntawm cov hlau thaum siv tuaj yeem ua kom ntseeg tau.
