Ti valve castings titala ku humesa swihoxo

1. Swilo swa stomata

Lexi i xirhendzevutani lexintsongo lexi vumbiwaka hi gasi leyi endlelo ro tiya ra nsimbi ri nga balekiki endzeni ka nsimbi. Rirhangu ra yona rale ndzeni ri rhetela naswona rina gasi, leyingana reflectivity yale henhla eka ultrasonic wave, kambe hikuva kahle kahle yiri spherical kumbe ellipsoid, i point defect, leswi khumbhaka amplitude ya yona ya reflection. Xirhendzevutani xa moya eka ingot xi flattened kuva ndzhawu ya xihoxo endzhaku ka forging kumbe rolling, leswi pfunaka kuva swikumeka hiku kumiwa ka ultrasonic.

2. Xiphemu xa slag

Slag eka maendlelo yo n’okisiwa kumbe refractory eka miri wa furnace yi rhurhumela eka nsimbi leyi nga mati, naswona yi katseka eka casting kumbe steel ingot loko yi cheriwa, leswi endlaka xihoxo xa slag clamp. Slag hi ntolovelo ayi vi kona yiri yoxe, yitala kuva yiri eka xiyimo xo enta kumbe yi hangalakile eka vuenti byohambana hambana, yifana na volume defects kambe yitala kuva na linearity yokarhi.

3. Ku hoxa swiphepherhele

Ku pandzeka eka casting swivangiwa ngopfu hi ntshikelelo wa shrinkage wa metal cooling solidification kutlula matimba yohetelela ya material, swifambelana na xivumbeko xa casting design na casting process, naswona switlhela swifambelana na cracking sensitivity ya thyaka rin’wana eka switirhisiwa swa nsimbi (kufana na sulphur yale henhla, cold brittleness, high phosphorus content, etc.). Eka spindle, kuta tlhela kuva na ku pandzeka eka shaft crystal, naswona eka billet forging leyi landzelaka, yita tshama eka forging tani hi ku pandzeka ka le ndzeni ka forging.

4. Pfuxeta nhlonge

Leswi i steelmaking kusuka eka ladle kuya eka ingot casting ingot, hikokwalaho ka ku kavanyeteka ka ku chela, ku yimanyana, ku cheriwa eka liquid metal surface eka moya hiku hatlisa ku kufumela xivumbeko oxide film, ku cheriwa lokuntshwa eka nsimbi ya mati swita tshoveka eka miri wa ingot naku vumba hierarchical (area) defects, yona eka ingot billet forging leyi landzelaka ayi forging.

5. Xivumbeko xa Anisotropy

Loko casting kumbe ingot yi titimela no tiya, rivilo ro kufumela kusuka ehenhla kuya exikarhi rihambanile, hikokwalaho tissue yohambana hambana ya crystallization yita vumbiwa, leswi kombisaka anisotropy ya swivumbeko swa michini, naswona switlhela swiyisa eka anisotropy ya swivumbeko swa acoustic, leswivulaka leswaku kuna rivilo rohambana ra mpfumawulo xikan’we naku hunguta mpfumawulo kusuka exikarhi kuya e henhla. Kuva kona ka anisotropy leyi swinga va na mbuyelo wo biha eka vukulu na ndzhawu ya swihoxo leswi kamberiweke hi nkarhi wa ku kumiwa ka ultrasonic.

Handle ka sweswo, Tianjin Tanggu Water Seal Valve Co., Ltd. i thekinoloji ya xiyimo xa le henhla ya elastic seat valve leyi seketelaka mabindzu, swikumiwa ielastic xitulu wafer phaphatani valve, lug valve ya phaphatani, double flange concentric valve ya phaphatani, flange yimbirhivalve ya phaphatani ya eccentric, valve yo ringanisela, valve yo kambela tipuleti timbirhi ta wafer, .Y-Xigwitsirisina swin’wana. Eka Tianjin Tanggu Water Seal Valve Co., Ltd., hi tinyungubyisa hi ku nyika switirhisiwa swa xiyimo xo sungula leswi fikelelaka swiyimo swa le henhla swa indasitiri. Hi nxaxamelo wa hina wo anama wa tivalvu na switirhisiwa, u nga hi tshemba ku nyika ntlhantlho lowu hetisekeke eka sisiteme ya wena ya mati. Tihlanganisi na hina namuntlha ku dyondza swo tala hi switirhisiwa swa hina na ndlela leyi hi nga ku pfunaka ha yona.
