1. Txhim kho lub zog thiab toughness ntawm cov yeeb nkab steel
Kev kho cua sov tuaj yeem txhim kho lub zog thiab tawv ntawm L360 roj av steel kav los ntawm kev kho lawv cov microstructure. Cov txheej txheem quenching thiab tempering tuaj yeem ua rau cov qauv sab hauv ntawm cov yeeb nkab steel ruaj khov, yog li txhim kho nws lub peev xwm los tiv thaiv cov khoom sab nraud. Qhov no yog ib qho tseem ceeb tshwj xeeb tshaj yog rau cov kav dej thauj mus los.
2. Txhim kho corrosion kuj ntawm steel kav
Kev kho cua sov tuaj yeem hloov kho cov tshuaj muaj pes tsawg leeg thiab cov qauv tsim ntawm cov yeeb nkab steel nto, yog li txhim kho nws cov corrosion kuj. Piv txwv li, cov txheej txheem carburizing thiab nitriding tuaj yeem tsim cov yeeb yaj kiab tiv thaiv ntom ntom ntawm cov yeeb nkab steel kom zoo tiv thaiv corrosion los ntawm cov xov xwm corrosive.
3. Txhim kho qhov kev ua haujlwm ntawm cov kav hlau steel
Kev kho cua sov tuaj yeem tshem tawm qhov kev ntxhov siab sab hauv tsim thaum lub sijhawm ua cov kav dej steel thiab txhim kho nws cov kev ua haujlwm vuam. Los ntawm cov txheej txheem annealing thiab normalizing, lub hardness ntawm cov yeeb nkab steel yuav txo tau thiab nws cov plasticity thiab toughness tuaj yeem txhim kho, ua rau nws tsis tshua muaj kab nrib pleb thiab tsis xws luag thaum lub sij hawm vuam txheej txheem.
4. Txhim kho qhov tseeb qhov tseeb ntawm cov kav hlau steel
Kev kho cua sov tuaj yeem txhim kho qhov tseeb qhov tseeb ntawm cov kav hlau los ntawm kev tswj lawv cov deformation. Cov txheej txheem quenching thiab tempering tuaj yeem ua rau kev ntxhov siab sab hauv ntawm cov yeeb nkab steel ntau dua, yog li txo qhov kev pheej hmoo ntawm deformation thaum ua thiab siv tom ntej.
5. Txuas lub neej kev pab cuam ntawm cov kav dej steel
Kev kho cua sov tuaj yeem txhim kho qhov hnav tsis kam thiab qaug zog ntawm cov kav dej steel, yog li txuas ntxiv lawv lub neej kev pab. Rau qee qhov kev thauj khoom siab thiab cov khoom siv hauv tsev siab, kev siv cov kav dej kub-kho tau tuaj yeem txo qhov zaus ntawm kev kho thiab hloov thiab txo cov nqi tu.
