Txheej txheem cej luam ntawm txoj kev kho cua sov rau seamless steel kav
Tom qab ua tiav los ntawm kev kos duab txias, txias dov thiab lwm yam txheej txheem, seamless steel kav yuav tsum tau kho cua sov los kho lawv cov khoom vim muaj kev hloov pauv hauv cov qauv siv lead ua thiab cov khoom siv kho tshuab. Txoj kev kho cua sov ntawm seamless steel kav feem ntau suav nrog annealing, normalizing, quenching thiab lwm txoj kev, uas tau qhia ib los ntawm ib qho hauv qab no.
Annealing kev kho cov kav hlau
Annealing yog ib txoj kev uas seamless steel kav yog rhuab mus rau ib tug tej yam kub thiab ces maj mam txias rau chav tsev kub. Txoj kev kho no tuaj yeem tshem tawm cov kev ntxhov siab sab hauv thiab cov ciam teb tsis tu ncua ntawm seamless steel yeeb nkab, yog li txhim kho nws cov plasticity thiab toughness thiab txhim kho nws cov khoom siv kho tshuab. Lub annealing kub thiab txias tus nqi yuav tsum tau txiav txim raws li cov khoom thiab cov duab ntawm seamless steel yeeb nkab. Feem ntau hais lus, qhov kub ntawm qhov annealing yuav tsum siab tshaj qhov tseem ceeb ntawm qhov kub ntawm cov khoom, thiab nws yuav tsum tau khaws cia rau ib lub sij hawm ntawm lub sij hawm tom qab rhuab mus rau qhov kub thiab txias kom tshem tawm tag nrho cov kev ntxhov siab.
Normalizing kev kho cov kav hlau
Normalizing kev kho mob yog ib txoj kev ntawm cua sov seamless steel kav mus rau ib tug kub ntawm 30 mus rau 50 degrees siab tshaj qhov annealing kub thiab sai txias nws nrog dej los yog lwm yam xov xwm. Txoj kev kho no tuaj yeem ua kom tawv ntawm cov kav dej seamless steel thiab txhim kho lawv cov hnav tsis kam thiab corrosion kuj. Lub normalizing kub thiab txias tus nqi yuav tsum tau txiav txim raws li cov khoom thiab cov duab ntawm seamless steel yeeb nkab. Feem ntau hais lus, qhov normalizing kub yuav tsum siab tshaj qhov ua hauj lwm hardening point, tab sis tsis siab dhau heev lawm kom tsis txhob muaj xws li tawg.
quenching kev kho cov kav hlau
quenching kev kho mob yog kom sov cov seamless steel yeeb nkab mus rau ib tug tej yam kub thiab ces sai sai muab tso rau hauv lub txias nruab nrab kom ceev nws txias. Txoj kev kho no tuaj yeem hloov pauv cov qauv ntawm cov kav dej seamless steel, ua cov martensite thiab khaws cia austenite, yog li ua rau nws cov hardness, lub zog thiab toughness. Lub quenching kub thiab txias tus nqi yuav tsum tau txiav txim raws li cov khoom thiab cov duab ntawm seamless steel yeeb nkab. Feem ntau, quenching kub yog siab tshaj qhov kub ntawm qhov tseem ceeb, thiab qhov txias txias yog txiav txim siab raws li kev ua haujlwm ntawm kev ua haujlwm thiab deformation peev xwm ntawm cov khoom.
Kev kho cua sov ntawm seamless steel kav yog txheej txheem nyuaj, thiab txoj kev kho kom tsim nyog yuav tsum tau txiav txim siab raws li cov khoom siv, cov duab thiab kev ua haujlwm ntawm seamless steel kav. Peb txoj kev ntawm annealing, normalizing, thiab quenching txhua tus muaj lawv tus yam ntxwv thiab sib txawv siv tau.
