Xa iinjineli zichaza Ingxubevange 21 kwi-high-pressure hydraulic valves okanye i-corrosion-resistant pump housings, abakhethi nje izinto eziphathekayo - babheja ngokuzinza kwe-dimensional, i-microstructural consistency, kunye ne-zero batch-to-batch drift kumandla esivuno. Yiyo loo nto ukukhangela kwinyani Ingxubevange 21 umzi-mveliso ibaluleke kakhulu kunangaphambili. Ayizizo zonke izinto ezifumanekayo ezinokubamba ukunyamezela kwe-± 0.02 mm kwi-350 mm ye-cobalt-nickel casting ngelixa igcina i-AMS 5387-ehambelana nesakhiwo sengqolowa emva kokunyanga kobushushu. Sibone iiprojekthi ezininzi zilibazisekile ngababoneleli abaphatha i-Alloy 21 "njengenye i-nickel alloy" - emva koko uzabalaza nencoko yomatshini, ukuqhekeka okungalindelekanga kwe-intergranular ngexesha lokuphumla koxinzelelo, okanye ukugqiba komphezulu osilela ukuqinisekiswa kwetyuwa-spray.
Kutheni i-alloy 21 ifuna ngaphezulu kwe-Standard Nickel Alloy Capability
I-alloy 21 (i-UNS N02021) ayiyona i-generic workhorse efana ne-Inconel 600. Umxholo wayo we-20% we-molybdenum uhambisa ukuchasana okukhethekileyo ekunciphiseni i-acids - kodwa kwakhona kwenza kube nzima ukuphosa ngokucocekileyo kunye nomatshini ngaphandle kokuqina komsebenzi. Kwivenkile yethu, siye salahla iibhetshi ezintathu zovavanyo lwezindlu zempompo yepiston ngaphambi kokuphucula ipateni yokuphuma kwesanti kunye nesantya serempu yokutshisa. Amava ehlabathi lokwenyani abonisa: ukuba umboneleli wakho akaqhubanga ubuncinci be-15 yokuvelisa izinto ezininzi ze-Alloy 21 phantsi kwe-ISO 9001 traceability, lindela ukukhukuliseka kwe-dimensional ngaphaya kwee-callouts ze-GD & T - ngakumbi kumacandelo amancinci angaphantsi kwe-4 mm.
Sihlala sivavanya i-alloy 21 billets ezingenayo sisebenzisa i-spark-OES kwaye siqinisekise ubungakanani beenkozo kwi-ASTM E112 nganye. Ngoba? Ngenxa yokuba ingxelo yokungahambelani komthengi omnye iveze ubushushu obunye obuneenkozo ezirhabaxa - ezilandelelwe emva kwixesha elingahambelaniyo lokufunxa iziko kwindawo yokusila. Eli qela liphumelele ikhemistri kodwa lasilela ubomi bokudinwa kuvavanyo lwasendle. Yinyani Ingxubevange 21 umzi-mveliso ayamkeli nje iicerts - iqinisekisa i-metallurgy emnyango.
Izakhono ezine ezingaxoxisiyo kufuneka uziqinisekise
Phambi kokuba usayine i-NDA okanye wabelane ngomzobo wakho we-GD&T, buza le mibuzo-kwaye ufune ubungqina:
- Ngaba uphosa i-Alloy 21 endlini - okanye ukunyibilika kwangaphandle? Ukunyibilika kokungeniswa kwe-off-site kwazisa ukuguquguquka kwenani lokubandakanywa kunye nomxholo wegesi. Siyancibilika kwaye sithulule i-Alloy 21 kwindawo yethu ye-vacuum-arc remelt (VAR) yokulawula amanqanaba e-oksijini ngaphantsi kwe-12 ppm.
- Ngaba oomatshini bakho be-CNC banokuphatha i-full-contour milling ye-Alloy eqinile 21 kwi-45 HRC? Izixhobo eziqhelekileyo ze-carbide ziyaphambuka. Sisebenzisa i-ceramic-tipped end Mills kunye ne-rigid hydrostatic spindles - kwaye sibeke iliso lokunxiba isixhobo nge-real-time acoustic emission sensors.
- Ngaba uyasenza isisombululo se-annealing kunye nokuguga endlwini - kunye ne-thermocouples eqinisekisiweyo kunye ne-calibrated furnaces? Amandla e-alloy 21 axhomekeke kwimijikelo ye-thermal echanekileyo. Idigri enye ngexesha lokwaluphala kutshintsha amandla okuqina ukuya kuthi ga kwi-80 MPa.
- Ngaba yonke inxalenye yabelwe i-ID ekhethekileyo ye-ID - kunye nokulandeleka ngokupheleleyo kubushushu bezinto ezikrwada, umhla wokuphosa, ukutshintshwa komatshini, kunye nengxelo yeCMM? Kwimizimba yeoyile kunye negesi yevalvu, oku akukhethi. Ifunwa yi-API 6A Annex F.
Kwenzeka ntoni xa utsiba iFactory ekhethekileyo
Abanye abathengi bazama ukonga iindleko ngokuhambisa iAlloy iinxalenye ezingama-21 kwiivenkile zemisebenzi ezinjongo ngokubanzi. Isiphumo? Iindlela ezintathu eziqhubekayo zokusilela silandelela kuzo zonke iimeko ezingama-42 zabathengi:
- I-Micro-cracking kwiindawo ezichaphazelekayo kubushushu -kubangelwa ukulawulwa kokushisa okungafanelekanga kwe-interpass ngexesha le-TIG welding ye-Alloy 21 flanges;
- Ukungazinzi kweDimensional emva komatshini wokugqibela - ngenxa yokukhululwa koxinzelelo olushiyekileyo kumacandelo anganciphisi-uxinzelelo ngaphambi kokugqiba;
- Ukugqobhoza komphezulu kwindawo zekloridi — ilandwe kwindawo yokuncipha kwechromium ukusuka ekusileni ngamandla ngaphandle kokudlula.
Sizilungisile zontathu - kodwa emva kokutyala imali kwi-Alloy 21 ezinikeleyo, i-ovens yokunciphisa uxinzelelo lwesantya, kunye neebhafu ze-citric-acid passivation eziqinisekisiwe nge-ASTM A967. Ezo ziseko zophuhliso azibizi. Kodwa zibiza ixabiso eliphantsi kunokutshintsha i-17 ye-winch center shaft rollers phakathi ebekwe kwinqanawa yenkxaso ekude nonxweme.
Ukwakha ukuthembeka, ubushushu obunye ngexesha
Ukuthembeka kuqala ngaphambi kokuba i-chip yokuqala ibhabhe. EQINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Yonke iAlloy 21 oda iqala ngokuphononongwa ngokudibeneyo kweemfuno zakho zokusebenza - hayi nje imilinganiselo. Siyabuza: Yintoni eyona nto iphezulu yoxinzelelo lokusebenza? Yintoni umjikelo womsebenzi olindelekileyo? Ngaba oku kuya kubona ukulayishwa kobushushu obujikelezayo? Lo mxholo ugqiba ukuba ngaba sicebisa ukugalelwa kwesanti + ukugqiba ukusebenza okanye utyalo-mali + ukususwa kwesitokhwe esincinci.
Ixesha lethu langoku lokukhokela kumthamo ophakathi we-Alloy 21 iiodolo ziiveki ze-12 - kungekhona ngenxa yokuba sicotha, kodwa ngenxa yokuba sicwangcisa ukushisa kwiibhloko ezintandathu ukuze siqinisekise imbali ye-thermal engaguqukiyo. Asingxameli iAlloy 21. Siyayihlonipha. Kwaye xa ivalve yakho yoxinzelelo kufuneka iphile kwimijikelo ye-15,000 kwi-3,000 psi ngaphandle kokuvuza, olo qeqesho luba ngumda wakho wokhuseleko.
Ukuba ufuna izinto ezichanekileyo ze-Alloy 21 ezakhelwe ukusebenza - hayi nje i-spec - qala ngomzi-mveliso ophatha i-metallurgy njengobunjineli, hayi izinto. Yiloo nto echaza into yokwenyani Ingxubevange 21 umzi-mveliso.
