High-strength steel yog ntxiv nrog ntau npaum li cas ntawm alloying ntsiab nyob rau hauv steel.Tom qab kev kho cua sov, cov ntsiab lus alloying ntxiv dag zog rau cov khoom siv, thiab cov qauv metallographic feem ntau yog martensite.Nws muaj lub zog loj thiab siab hardness, thiab nws qhov cuam tshuam toughness kuj siab dua 45 steel.Lub zog txiav thaum txiav yuav yog 25% -80% siab tshaj qhov txiav quab yuam ntawm qhov txiav 45, qhov siab dua qhov txiav yog, thiab cov chips nyuaj dua.Yog li, hauv kev tsim khoom tiag tiag, ua li cas cov hlau muaj zog txiav?
1. Cov cuab yeej
Rau roughing thiab cuam tshuam txiav, lub cuab yeej yuav tsum muaj thermal shock resistance.Ntxiv nrog rau cov cuab yeej pob zeb diamond, txhua yam khoom siv cuab yeej tuaj yeem txiav.Thaum xaiv cov cuab yeej siv, lawv yuav tsum tau xaiv raws li cov txheej txheem txiav.
A. Kev kub ceev steel
Kev xaiv ntawm high-performance high-speed steel rau txiav high-strength thiab ultra-high-strength steel yuav tsum yog raws li nyob rau hauv lub zog, zoo, kev ua thiab rigidity ntawm cov txheej txheem system, thiab comprehensively xav txog lub tshav kub tsis kam, hnav kuj thiab toughness ntawm cov khoom siv.Thaum cov txheej txheem muaj kev nruj nruj thiab cov cuab yeej profile yooj yim, tungsten-molybdenum-raws li, high-carbon low-vanadium-muaj aluminium high-speed steel lossis tungsten-molybdenum-based high-carbon low-vanadium high-cobalt high- ceev steel yuav siv tau;Nyob rau hauv kev cuam tshuam tej yam kev mob, tungsten-molybdenum yuav siv tau.High vanadium siab ceev steel.
B. hmoov metallurgy kev kub ceev steel thiab Tin coated kev kub ceev steel
Hmoov metallurgy high-speed steel yog cov hmoov kub ceev uas ncaj qha nias ntawm qhov kub thiab txias, thiab tom qab ntawd forged rau hauv cov cuab yeej tsim nyog.Nws yog sharpened tom qab ua thiab muaj siab hardness thiab siab hnav tsis kam.Nws yog tsim rau high-strength steel thiab super.Txiav ntawm high-strength steel.
C. Cemented carbide
Cemented carbide yog cov khoom siv tseem ceeb rau kev txiav high-strength thiab ultra-high-strength steels.Feem ntau, kev ua haujlwm siab tshiab hard alloys lossis coated hard alloys yuav tsum raug xaiv.
D. Ceramic riam
Nws hardness thiab kub tsis kam yog siab dua li ntawm cov alloys nyuaj, tso cai txiav ceev 1-2 zaug siab dua cemented carbides.Hauv kev txiav cov hlau muaj zog thiab ultra-high-strength steel, cov cuab yeej ceramic feem ntau yog siv hauv cov ntawv hlau ua haujlwm thiab precision machining.
2. Txiav tus nqi
Kev txiav ceev ntawm kev xa cov hlau muaj zog yuav tsum yog 50% -70% qis dua qhov txiav ceev ntawm cov hlau dav dav.Qhov siab dua lub zog thiab hardness ntawm cov khoom siv ua haujlwm, qhov kev txiav ceev yuav tsum qis dua.Txiav ceev ntawm high-strength steel txiav high-strength steel yog (3-10) m / min, carbide cuab tam (10-60) m / min, ceramic cuab tam yog (20-80) m / min, CBN cuab tam yog (40 -220) m / min.Qhov tob ntawm kev txiav thiab pub yog tib yam li rau kev tig hlau.
3. Chip rhuav txoj kev
Vim lub siab tensile lub zog ntawm high-strength steel, nws tsis yooj yim rau tawg lub nti thaum tig, uas ua rau nws nyuaj heev rau txoj kev khiav ntawm txoj siav.Nws yog ib qho tsim nyog yuav tsum tau them sai sai rau qhov no hauv kev ua haujlwm.
