Stainless simbi chubhuKupisa kurapwa chinangwa chikuru ndechekuchinja mukati pombi simbi matrix chimiro, kuvandudza kuoma kwesimbi isina tsvina pombi, asi nekuti haina kunyatso chinja pombi morphology, uye saka haigone kunyatso kuvandudza simba uye kuoma kwesimbi isina tsvina chubhu.Stainless simbi chubhu inodzima tembiricha inofanira kusarudzwa mune chaiyo yakakosha tembiricha 30-70℃, nekuda kwehurombo hwekupisa conductivity yesimbi, nguva yekubata inowanzowedzera kaviri kupfuura simbi.

Zvichakadaro, kuti uderedze quenching kushushikana, kusati kwadzima kunofanirwa kunge kuri mumhepo kusati kwatonhora, mafuta ekudzima svikiro anowanzo shandisa simba kudzivirira kudzima kutsemuka anogona zvakare kutora mafuta ekutanga (akatonhodzwa kusvika 200-300.℃) kutonhora kwemhepo.Mushure mesimbi isina tsvina yechubhu kudzima, martensite matrix chimiro chinogona kuve kana troostite mushure mekushatirwa kudzika kuita sorbite, iyo inodzima, kupisa maitiro uye kudziya simbi isina tsvina pombi imwe pombi hapana yakakosha mutsauko mushure mekudzima kunofanirwa kudziya simbi isina tsvina.Simbi isina simbi inogona zvakare kuve isothermal quenching isothermal quenching medium inogona kupisa mafuta kana nitrate, semuenzaniso, pa830-870.℃, uye ipapo kupisa kudzima 280-350℃isothermal nitrate.Simbi pombi kudzima kana isothermal quenching, kunatsiridza michina zvivakwa pane yakajairwa grey cast iron inoshamisa.

Kuti uvandudze kuomarara kwepasi uye kupfeka kuramba kwepombi yesimbi isina tsvina, inogona kuomesa pamusoro pemoto, kuomarara kwepamusoro-soro uye kurapwa kwemakemikari ekupisa, umo ma frequency epakati kana epakati frequency epamusoro anoomesa maapplication mazhinji.Yakakwira, yepakati frequency kuomarara pamwe nenguva yekudziya ipfupi, kushoma oxidation uye decarbonization, deformation idiki, uye nyore kushanda, tembiricha yekudziya inowanzo 850-950.℃, pombi yesimbi isina tsvina nekuda kwekusagadzikana kwemafuta, uye kunyungudika kwakaderera, mwero wekudziya haukurumidze zvakanyanya, kana ukasaita kuputika kana kunyungudika.Yakakwira, yepakati frequency kugadzirisa Stainless simbi chubhu haingogone kuvandudza kuoma kwepasi uye kupfeka kuramba, asiwo zvakanyanya kunatsiridza simba rekuneta, kuwedzera hupenyu hwesevhisi, imwe yacho, Muchina Chishandiso chemagetsi chekubata pamusoro pekudziya muenzaniso wakajairwa wesimbi isina tsvina. kuoma kwechubhu.Kuti uwane yakanaka matrix sangano kuti ive nechokwadi Stainless simbi chubhu mukati pamusoro kuoma uye michina zvinhu zvinogona kuwanikwa pashure yakakwirira kuoma, pamusoro kupisa kurapwa pamberi yakanakisisa asati normalizing kana quenching uye tempering kurapwa.
