Sumo Yezvinhu Uye Zvakanakira
Sekristaro yemazuva ano maindasitiri ekugadzira tekinoroji, iyo AISI 316LStainless simbi yekukandira marigearbox dzimba haingoratidzi runako rwakasiyana rweAISI 316L simbi isina tsvina, asi zvakare inowana yakakwirira-chaiyo kudzokororwa kwezvimiro zvakaoma kuburikidza neyekare uye yakanaka maitiro eInvestment casting. AISI 316L simbi isina tsvina, senhengo yeaustenitic simbi isina tsvinaakatevedzana, anomira pakati pezvizhinji zvesimbi isina simbi yeakanakisa kuramba corrosion, yakakwira tembiricha kuramba uye yakanaka michina zvivakwa. Kunyanya mushure mekuwedzera kwe molybdenum, kugona kwayo kuramba gomba, kukoromoka kwegora uye kusagadzikana corrosion kuputika kunowedzerwa zvakanyanya, zvichiita kuti chinyorwa ichi chive chinhu chinofarirwa muminda yakawanda senge indasitiri yemakemikari, kugadzira chikafu, uye mainjiniya emugungwa.
Kemikari yakagadzirwa uye microstructure
Iyo kemikari inoumbwa yeAISI 316L simbi isina tsvina inodzorwa zvakanaka kuti ive nechokwadi chayo chakanakisa chemuviri uye chemakemikari zvimiro. Iyo yakaderera kabhoni yemukati (≤0.03%) inodzivirira zvinobudirira dambudziko reiyo intergranular corrosion panguva yewelding uye inovandudza iyo yakazara corrosion kuramba kwezvinhu. Zvemukati zvechromium (16.5% -18.5%) uye nickel (12% -15%) zvinopa zvinhu zvakanakisa oxidation kuramba uye kuomarara, nepo 2% -3% yemolybdenum inovandudza zvakanyanya kusagadzikana kwayo mukuora munzvimbo dzechloride. Mukuwedzera, huwandu hwakakodzera hwe nitrogen (≤0.10%) inowedzera kuwedzera kusimba uye kuoma kwezvinhu pasina kupa kuoma kwayo. Iyi yakagadziridzwa kemikari yekuumbwa musanganiswa, yakasanganiswa neyakanaka uye yunifomu microstructure yakaumbwa panguva yekudyara kwekudyara maitiro, inogonesa iyo 316L giya bhokisi rekugara kuchengetedza kugadzikana kwakanaka uye kusimba pasi pemamiriro akaomarara ekushushikana.
Mechanical properties uye simba rekuita
AISI 316L Stainless simbi giya bhokisi dzimba inoitawo zvakanaka maererano nemakanika zvivakwa. Simba rayo rekusimba rinowanzova pakati pe485-620 MPa, uye simba rayo rekubereka riri muhuwandu hwe170-300 MPa, izvo zvinoreva kuti kunyange pasi pemamiriro ezvinhu akaoma, imba yacho inogona kuchengetedza kutendeseka kwemaitiro uye haisi nyore kune deformation yepurasitiki kana kuputsika. Panguva imwecheteyo, kurebesa kweanosvika makumi mana muzana uye kunaka kwesimba kusimba kunovimbisa kuchengetedzeka uye kuvimbika kweimba kana yaiswa pamitoro. Pamusoro pezvo, AISI 316L simbi isina tsvina zvakare ine yakanakisa kudzika-tembiricha kuomarara uye inogona kuchengetedza yakagadzikana mechanicha nzvimbo munzvimbo dzinotonhora zvakanyanya, izvo zvinonyanya kukosha kune michina inoda kushanda munzvimbo dzepolar kana dzakadzika-gungwa.

Mienzaniso Yekushandisa uye Kukosha kweGearbox Housing
AISI 316L simbi isina tsvina yekudyara inokandira magiya bhokisi dzimba inoita basa risingadzokerike munzvimbo dzakawanda dzakakosha.
Muindasitiri yepetrochemical, segomba reiyo core transmission components, haingomirire tembiricha yakakwira uye kudzvanywa kwenzvimbo yekushanda, asi zvakare kuramba kukukurwa kwezvakasiyana siyana zvinoodza media kuti ive nechokwadi chekushanda kwakagadzikana uye kuvimbika kwenguva refu kwemidziyo.
Pamapuratifomu ekumahombekombe, AISI 316L simbi isina tsvina yegiya bhokisi dzimba dzave zvinhu zvakakosha zvekutyaira makiyi emidziyo yakaita sejenareta nemacompressor nekuda kwekusagadzikana kwemvura yegungwa.
Uye zvakare, mukugadzira chikafu, mishonga uye mamwe maindasitiri, hutsanana hunhu hweAISI 316L simbi isina tsvina inoita kuti ive iyo inosarudzika zvinhu zvemichina zvinosangana nechikafu, kuve nechokwadi chekuchengetedza uye kuchena kwechigadzirwa.
