Quenching thiab Tempering kho: Quenching tuaj yeem ua rau cov hlau tau txais cov qauv martensite. Martensite yog microstructure nrog siab hardness thiab lub zog. Nyob rau hauv cov ntaub ntawv ntawm kev txo cov ntsiab lus carbon, ib tug tsim nyog quenching thiab tempering txheej txheem yuav xyuas kom meej lub zog ntawm cov hlau. Lub quenching kub yuav tsum raug tswj kom raug raws li cov khoom sib xyaw ntawm cov hlau kom tsis txhob muaj qhov tsis tsim nyog microstructure vim dhau - siab lossis dhau - qis. Tempering yog tshem tawm cov kev ntxhov siab sab hauv tsim los ntawm quenching thiab txhim kho toughness. Piv txwv li, siv qhov kub thiab txias (150 - 250 degree) tuaj yeem txhim kho toughness rau qee yam thaum tuav lub zog siab. Nyob rau hauv no tempering kub ntau, martensite decomposes rau hauv tempered martensite, txo cov brittleness ntawm hlau thaum tuav lub zog siab.

 

Optimization ntawm Steel Processing Technology

 

Tswj Rolling thiab Tswj Txias Technology: Thaum lub sij hawm dov cov txheej txheem ntawm cov hlau, kev siv cov cuab yeej tswj dov tuaj yeem kho cov nplej thiab txhim kho lub zog ntawm cov hlau. Piv txwv li, thaum lub sij hawm kub - dov txheej txheem, los ntawm kev tswj tsis xws li dov kub, tus naj npawb ntawm dov kis, thiab txo tus nqi, cov hlau yuav undergo dynamic recrystallization thaum dov, li no refining cov nplej. Nyob rau tib lub sijhawm, ua ke nrog kev tswj cov tshuab cua txias, qhov tsim nyog txias tuaj yeem raug saws tom qab dov los tswj cov microstructure thiab cov khoom ntawm cov hlau. Piv txwv li, siv tshuab ua kom txias txias tuaj yeem ua rau cov hlau kom tau txais cov pob zeb pearlite microstructure zoo dua thaum lub sij hawm hloov ntawm austenite mus rau pearlite, txhim kho lub zog ntawm cov hlau. Txoj kev no ntawm kev txhim kho lub zog ntawm cov hlau los ntawm kev tswj cov microstructure los ntawm kev siv thev naus laus zis tuaj yeem ua kom muaj zog ntawm cov hlau thaum txo cov ntsiab lus carbon.

Forging txheej txheem optimization: Rau qee cov hlau uas yuav tsum tau forging, optimizing txheej txheem forging kuj tuaj yeem txhim kho lub zog thaum cov ntsiab lus carbon txo. Thaum lub sij hawm forging txheej txheem, tsis xws li forging kub, forging ratio, thiab forging ceev yuav tsum tau tswj kom tsim nyog. Piv txwv li, tsim nyog nce qhov sib piv ntawm forging tuaj yeem ua rau sab hauv microstructure ntawm steel ntau compact thiab txhim kho lub zog. Qhov kub forging yuav tsum tau txiav txim siab raws li cov khoom sib xyaw ntawm cov hlau thiab cov duab kos los xyuas kom meej tias cov hlau yog forged nyob rau hauv qhov kub thiab txias thiab tsis txhob cuam tshuam microstructure los ntawm overheating los yog tshaj - txias. Los ntawm kev ua kom zoo ntawm cov txheej txheem forging, cov hlau tuaj yeem tau txais kev ua haujlwm zoo nrog cov ntsiab lus qis dua.
