Hydraulic solenoid valve SV16-20 yog threaded nrog electromagnetic siab tswj valve DHF16-220 nquag kaw AC220V solenoid valve
Hlau infiltration txoj kev
◆ Muab lub workpiece tso rau hauv borax da dej nrog diffusion ntsiab los yog lawv cov alloys, thiab tsim high-hardness carbide txheej xws li V, Nb, Cr thiab Ti rau ntawm qhov chaw ntawm lub workpiece. Txoj kev kho no hu ua: hlau infiltration (TD) method. Cov txheej txheem no ruaj khov, tsis muaj kuab paug, thiab qhov chaw ntawm qhov chaw yog huv si, uas yog qhov zoo tshaj plaws super-strength hardening thev naus laus zis, yog li txhim kho cov kev pab cuam lub neej ntawm qhov chaw. TD cov ntaub ntawv da dej yog ua los ntawm 40 ‰ ~ 80 ‰ Ni, 10 ‰ ~ 30 ‰ Cr alloy lossis Fe-Ni-Cr alloy, uas muaj qhov muaj zog tshaj corrosion thiab oxidation tsis kam.
Txoj kev Infiltration
InfilT Infiltration txheej tuaj yeem tsim cov txheej txheem tseem ceeb rau ntawm qhov chaw, tab sis kuj tsis tuaj yeem txhim kho lub zog corrosion, tab sis kuj tsis muaj kev qaug zog ntawm cov hlau tsis-stainless thiab lub hardness ntawm seem uas tsis tuaj yeem raug quenched. Nws yog ib txoj hauv kev zoo los txhim kho lub neej kev pab cuam ntawm ultra-siab siab valve qhov chaw.
Laser nto kho
◆ Laser nto kho tshuab tuaj yeem txhim kho cov khoom siv kho tshuab, metallurgical zog thiab lub cev ntawm cov khoom nto, thiaj li txhim kho cov hnav tsis kam, corrosion kuj thiab qaug zog tsis kam ntawm qhov chaw kom ua tau raws li qhov xav tau ntawm kev ua haujlwm sib txawv. Laser nto kev kho mob yog ib txoj kev siv technology uas siv lub zog ceev ceev laser beam kom sov rau saum npoo ntawm cov khoom nyob rau hauv ib txoj kev tsis sib cuag kom paub nws cov kev hloov kho deg. Laser nto kho yog muab faib ua laser quenching, laser nto melting thiab laser nto alloying. Laser nto melting ntawm W18Cr4V kev kub ceev hlau tau nqa tawm. Hwj chim ntses 1200W ua rau saum npoo me ntsis molten. Lub hardness tuaj yeem nce mus rau 70HRC. Lub hardness ntawm zoo tib yam quenching yog 62 ~ 64 HRC.
