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

Kev Xav Tau Xeem

Kev kuaj hydraulic
Yuav tsum kuaj hydraulic rau cov kav hlau ib qho zuj zus. Qhov siab tshaj plaws ntawm kev kuaj yog 20 MPa. Nyob rau hauv qhov kev kuaj siab, lub sijhawm ruaj khov yuav tsum tsis pub tsawg dua 10 vib nas this, thiab tsis pub xau cov kav hlau.
Kev sim ua kom tiaj tus
Kev sim ua kom tiaj tus yuav tsum tau ua rau cov yeeb nkab hlau uas muaj txoj kab uas hla sab nraud loj dua 22 hli
Kev sim flaring
Cov kav hlau carbon zoo thiab cov kav hlau stainless (tsis kub) uas muaj txoj kab uas hla sab nraud tsis pub tshaj 76 hli thiab phab ntsa tuab tsis pub tshaj 8 hli yuav raug kuaj kom nthuav dav. Kev kuaj flaring yuav tsum tau ua ntawm chav sov. Qhov nrawm flaring ntawm txoj kab uas hla sab nraud ntawm cov qauv tom qab lub plawv sab saud taper yog 60% ntawm flaring yuav tsum ua tau raws li qhov yuav tsum tau ua ntawm lub rooj 7. Tsis pub muaj kab nrib pleb lossis kab nrib pleb ntawm cov qauv tom qab flaring. Raws li qhov yuav tsum tau ua ntawm tus neeg thov thiab tau sau tseg hauv daim ntawv cog lus, cov hlau alloy kuj tseem siv tau rau kev kuaj kom nthuav dav.
Kev kuaj tsis puas tsuaj
Cov kav hlau yuav tsum raug kuaj xyuas qhov tsis zoo ntawm ultrasonic ib qho los ntawm ib qho raws li cov kev cai ntawm GB / T 5777-2008. Raws li qhov yuav tsum tau ua ntawm tus neeg thov, lwm cov kev ntsuam xyuas tsis puas tsuaj tuaj yeem ntxiv tom qab kev sib tham ntawm tus neeg muag khoom thiab tus neeg thov thiab qhia hauv daim ntawv cog lus.
Kev kuaj xeb intergranular
Yuav tsum ua qhov kev sim xeb intergranular rau cov yeeb nkab hlau stainless (tsis kub). Txoj kev sim yuav tsum ua raws li cov kev cai ntawm txoj kev Suav E hauv GB / T 4334-2008, thiab qhov kev xeb intergranular tsis raug tso cai tom qab kev sim.
Tom qab kev sib tham ntawm tus neeg muag khoom thiab tus neeg thov, thiab tau sau tseg hauv daim ntawv cog lus, tus neeg thov tuaj yeem xaiv lwm txoj kev kuaj xeb.
