Incazelo emfushane:

I-DIN 17745 4j36 Invar Alloy Wire I-Alloy Yokukhulisa Okuphansi I-Feni36 Wire

(Igama Elivamile: Invar, FeNi36, Invar Standard, Vacodil36)

I-4J36 (Invar), eyaziwa nangokuthi i-FeNi36 (64FeNi e-US), iyi-alloy ye-nickel-iron ephawulekayo nge-coefficient yayo ephansi kakhulu yokwanda kokushisa (i-CTE noma i-α).

Imibuzo Evame Ukubuzwa

Amathegi Omkhiqizo

4J36 (I-Invar) isetshenziswa lapho kudingeka khona ukuzinza okuphezulu, njengezinsimbi zokunemba, amawashi, ama-seismic creep gauges, ozimele be-TV shadow-mask, ama-valve kuma-motor, kanye namawashi alwa ne-magnetic. Ekuhlolweni komhlaba, lapho kufanele kwenziwe i-first-order (high-precision) elevation leveling leaving, i-Level staff (induku yokulinganisa) esetshenziswayo yenziwe ngeI-Invar, esikhundleni sokhuni, i-fiberglass, noma ezinye izinsimbi. Ama-Invar strut ayesetshenziswa kwamanye ama-piston ukuze anciphise ukwanda kwawo kokushisa ngaphakathi kwamasilinda awo.

I-4J36 isebenzisa ukushisela kwe-oxyacetylene, ukushisela kwe-arc kagesi, ukushisela kanye nezinye izindlela zokushisela. Njengoba i-coefficient yokwanda kanye nokwakheka kwamakhemikhali kwe-alloy kuhlobene kufanele kugwenywe ngenxa yokuthi ukushisela kubangela ushintsho ekwakhekeni kwe-alloy, kungcono ukusebenzisa i-Argon arc welding welding filler metals okungcono ukuthi iqukethe i-titanium engu-0.5% kuya ku-1.5%, ukuze kuncishiswe ukugoba kwe-weld kanye nokuqhekeka.

Inqubo yokwelapha ukushisa
Ukuhlanza ukucindezeleka	Kushiswe kufike ku-530~550ºC bese ubamba ihora eli-1~2. Kubanda
ukubopha	Ukuze kuqedwe ukuqina, okumele kukhishwe ngenqubo yokudonsa ebandayo negoqiwe. Ukufaka i-Annealing kudinga ukushiswa kufikela ku-830 ~ 880ºC ku-vacuum, gcina imizuzu engama-30.
Inqubo yokuzinzisa	Ku-media yokuvikela bese kushiswa ku-830 ºC, bamba imizuzu engama-20. ~ ihora eli-1, cisha Ngenxa yokucindezeleka okubangelwa ukucima, kushiswa ku-315ºC, gcina ihora eli-1 ~ 4.
Izinyathelo zokuzivikela	Ayikwazi ukuqina ngokwelashwa ngokushisa Ukwelashwa kwendawo kungaba ukuqhumisa isihlabathi, ukupholisha noma ukukha amanzi. Ingxube ingasetshenziswa isisombululo se-25% se-hydrochloric acid pickling ku-70 ºC ukuze kusulwe indawo eyomile.
