440 Stainless Hlau Yeeb Nkab Kev Kho Mob

440 stainless hlau yeeb nkab nto kho

Kev kho cua sov ntawm 440 stainless hlau yeeb nkab feem ntau muaj ob txoj haujlwm tseem ceeb: annealing thiab quenching. Cov txheej txheem no yog qhov tseem ceeb rau kev ua tiav cov khoom siv kho tshuab uas xav tau thiab txhim kho cov hlau microstructure.

Nov yog cov lus piav qhia ntxaws txog cov kauj ruam kho cua sov:

1, Kev xa tawm:

1) Cua sov: 440 stainless hlau yeeb nkab yog rhuab mus rau qhov kub thiab txias, feem ntau ntawm 800 degree (1472 degree F) thiab 1050 degree (1922 degree F). Qhov ntsuas kub yog nyob ntawm qib tshwj xeeb thiab cov khoom xav tau.

2) Soaking: Thaum cov yeeb nkab mus txog qhov ntsuas kub uas xav tau, nws tau tuav ntawm qhov ntsuas kub rau lub sijhawm tshwj xeeb. Lub sij hawm soaking tso cai rau cov cua sov kom uniformly nkag mus rau hauv cov hlau thiab pib qhov xav tau hloov pauv hauv nws cov microstructure. Lub sij hawm ntub dej tuaj yeem nyob ntawm ob peb feeb mus rau ob peb teev, nyob ntawm seb cov yeeb nkab loj thiab tuab.

3) Kev tswj kom txias: Tom qab lub sij hawm ntub dej, cov yeeb nkab steel hlau yog txias maj mam hauv qhov kev tswj xyuas. Qhov no tuaj yeem ua tau los ntawm kev tua cov cua sov thiab tso cai rau cov yeeb nkab kom txias hauv lub cub tawg, lossis los ntawm kev siv cov txheej txheem txias xws li lub tshuab cua txias lossis cua txias. Kev ua kom txias qeeb yuav pab txo qis kev ntxhov siab sab hauv thiab ua kom muaj qhov xav tau microstructure.

2, Quenching:

1) Cua sov: Tom qab cov txheej txheem annealing, cov yeeb nkab steel hlau rov qab rau qhov kub siab tshaj nws qhov kub thiab txias, feem ntau nyob ib ncig ntawm 1000 degree (1832 degree F) txog 1100 degree (2012 degree F).

2) quenching nruab nrab: Cov yeeb nkab rhuab yog ces txias sai heev los ntawm immersing nws nyob rau hauv ib tug quenching nruab nrab, xws li roj, dej, los yog polymer daws. Kev xaiv ntawm quenching nruab nrab nyob ntawm qhov xav tau hardness thiab cov khoom ntawm cov khoom kawg.

3) Cov cua txias nrawm: Lub quenching nruab nrab tshem tawm cov cua sov los ntawm cov yeeb nkab steel hlau sai, ua rau tsim cov microstructure hardened. Cov cua txias ceev ceev tiv thaiv kev tsim cov pob zeb loj, softer thiab txhawb kev tsim cov me me, nyuaj martensite crystals. Qhov no ua rau muaj zog ntxiv thiab txhim kho cov khoom siv kho tshuab, xws li lub zog thiab hnav tsis kam.
