Rau cov hlau nrog phab ntsa tuab tsawg dua 5 hli raj tsis ua rau kev sim hardness

Kev xeem yuav tsum tau ua

Kev Kuaj Hydraulic
Kev ntsuas kev ntsuas hydraulic yuav tsum tau nqa tawm rau cov kav hlau hlau ib qho los ntawm ib qho. Qhov ntsuas qhov siab tshaj plaws yog 20 MPA. Nyob rau hauv qhov kev ntsuas siab, lub sijhawm ua haujlwm ruaj khov yuav tsum tsis pub tsawg tshaj 10 s, thiab to steel yeeb nkab tsis pub.
Plhaw kev kuaj
Flattening kev kuaj mob yuav tsum tau ua rau cov yeeb nkab steel nrog rau txheej hla ntau dua 22 hli
Flaring Test
Zoo siab carbon txheej txheem hlau thiab stainless-resistant) steel kav ntawm tsis ntau tshaj li 76 mm thiab ib phab ntsa tuab ntawm tsis ntau tshaj 8 hli yuav raug nthuav dav. Txoj kev npau taws yuav tsum nqa tawm ntawm chav tsev kub. Lub Inch sab nraud Flaring tus nqi ntawm cov qauv tom qab taper Core Taper yog 60% ntawm cov kab nrib pleb Raws li cov kev xav tau ntawm cov neeg xav tau thiab sau tseg hauv daim ntawv cog lus, cov hlau alloy txheej txheem kuj tseem tuaj yeem siv rau kev ntsuas.
Nondestructive Teste
Tus kav hlau hlau yuav tsum raug ultrasonic qhov khuam nrhiav kom muaj ib qho los ntawm ib qho nyob rau hauv raws li cov kev cai ntawm GB / T 5777-2008. Raws li cov cai yuav tsum tau ua ntawm cov neeg xav tau, lwm yam kev ua txhaum cai tsis ua txhaum cai ntxiv tom qab kev sib ceg ntawm cov khoom xa khoom thiab cov xav tau thiab qhia hauv daim ntawv cog lus.
Sib Tw Sib Tham Corrosion
Kev xeem corrosion yuav tsum tau ua rau stainless (kub-resistant) steel yeeb nkab. Txoj kev xeem yuav tsum ua raws li cov kev cai ntawm Suav cov qauv e hauv GB / T 4334-2008, thiab intergranular corrosion nyiam tsis pub tom qab kuaj.
Tom qab kev sib raug zoo ntawm cov chaw muag khoom thiab cov neeg xa khoom, thiab sau tseg hauv daim ntawv cog lus, qhov xav tau tuaj yeem xaiv lwm cov kev xeem corrosion.
