Rau cov hlau nrog phab ntsa thickness tsawg dua 5 hli raj tsis ua hardness sim

Kev Xeem Xeem

Hydraulic xeem
Kev ntsuas hydraulic yuav tsum tau ua rau cov kav hlau ib leeg. Qhov ntsuas siab tshaj plaws yog 20 MPa. Nyob rau hauv qhov kev sim siab, lub sij hawm stabilization yuav tsum tsis pub tsawg tshaj 10 s, thiab tsis tso cai rau xau ntawm cov yeeb nkab steel.
Kev ntsuam xyuas
Kev ntsuas flattening yuav tsum tau ua rau cov yeeb nkab steel nrog txoj kab uas hla sab nraud ntau dua 22 hli
Flaring xeem
High quality carbon steel structural steel thiab stainless (heat-resistant) steel kav nrog ib tug txheej txoj kab uas hla ntawm tsis ntau tshaj 76 hli thiab phab ntsa thickness ntawm tsis ntau tshaj 8 hli yuav tsum raug rau expanding xeem. Qhov ntsuas flaring yuav tsum tau ua nyob rau hauv chav tsev kub. Sab nraud txoj kab uas hla flaring tus nqi ntawm cov qauv tom qab lub sab saum toj core taper yog 60% ntawm cov flaring yuav tsum tau raws li qhov yuav tsum tau ntawm lub rooj 7. Tsis muaj kab nrib pleb los yog kab nrib pleb nyob rau hauv cov qauv tom qab lub flaring. Raws li cov kev xav tau ntawm tus neeg thov thiab tau sau tseg hauv daim ntawv cog lus, cov hlau alloy steel kuj tuaj yeem siv rau kev nthuav dav.
Nondestructive teste
Cov kav hlau yuav tsum raug kuaj xyuas qhov tsis zoo ntawm ultrasonic ib los ntawm ib qho raws li cov kev cai ntawm GB / T 5777-2008. Raws li cov kev xav tau ntawm tus neeg thov, lwm yam kev ntsuas tsis muaj kev puas tsuaj tuaj yeem raug ntxiv tom qab kev sib tham ntawm tus neeg muag khoom thiab tus neeg thov thiab qhia hauv daim ntawv cog lus.
Intergranular corrosion test
Intergranular corrosion test yuav tsum tau ua rau stainless (heat-resistant) steel yeeb nkab. Txoj kev xeem yuav tsum ua raws li cov kev cai ntawm Suav txoj kev E hauv GB / T 4334-2008, thiab intergranular corrosion nyiam tsis pub tom qab kuaj.
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 corrosion.
