1.4825 (EN 10295 chiyero, giredhi GX25CrNiSi18-9) is an austenitic heat-resistant cast stainless steel rakagadzirirwa zvakanyanya-tembiricha, rinorema{7}kuremerwa uye nharaunda dzinoita ngura. Nekuumbwa kwayo kwekemikari uye kugadzikana kwemicrostructure, yave iyo inoshandiswa pakupfekwa kwepamusoro-kupfekwa kwekushisa{10}}zvikamu zvisingachinjiki mumetallurgy, simba, chemical engineering nemamwe maindasitiri. Inopa kusapisa kupisa kwakanyanya, kusapfeka uye kusaita ngura munguva yakareba-yepamusoro-sevhisi yekupisa.
I. Core Material Properties (Kuumbwa & Microstructure)
Kuita kwe1.4825 kunobva kune kwayo chaiyo makemikari kuumbwa uye yakagadzikana austenitic matrix, mukuteerana kwakazara neEuropean standard EN 10295.
High Chromium (17–19%): Inogadzira firimu rinodzivirira uye rinogara riri Cr₂O₃ pamusoro, rinoisa mweya weokisijeni uye corrosive media, ichiburitsa yakakwira{2}}tembiricha oxidation kuramba. Inogona kushanda zvakadzikama pa900℃(1173K) kwenguva refu-uye kushingirira-tembiricha yenguva pfupi iri pamusoro pe1000 degrees (1273K).
Medium Nickel (8-10%): Inodzikamisa iyo austenitic matrix, kuve nechokwadi kuti hapana shanduko yechikamu uye zviyero zvakagadzikana pakupisa kwakanyanya. Zvinonatsiridzawo kusimba kwepamusoro-kusimba kwekushisa uye kushivirira kwemafuta pakukwira bhasikoro.
Silikoni (0.5–2.5%): Inosimudzira kugadzikana kwefirimu reoxide, kunyanya kunatsiridza kusimba kune yakakwira-kuwora mumhepo yesarufa{{3}ine uye huruva-yakaremerwa nemhepo, yakanakira kuvira kweindasitiri nezvimba zvekupisa.
Carbon (0.15–0.35%): Mafomu akaparadzirwa Cr₂₃C₆ carbides, achiwedzera zvakanyanya-simba retembiricha, kusatsika uye kuramba kupfeka pasina kurega kuomarara.
II. Makiyi Mabhenefiti: Kudzivirira Kupisa, Kupfeka Resistance & Corrosion Resistance
1. Yakanakisa Yepamusoro-Kugadzikana kweTembiricha & Kudzivirirwa neCreep
Tembiricha yenguva refu-yenguva refu inosvika 900 degrees , -yenguva pfupi inokwira kusvika 1000 degrees .
Kukambaira kukuru uye simba rekutsemuka pasi pe-tembiricha uye inorema-mamiriro ezvinhu; hapana deformation kana kuderera panguva yekushandiswa kwenguva refu-.
Yakasarudzika yekupisa kuneta kuramba uye kupisa kwekupwanya kuramba, kwakakodzera kugara uchidziya uye kutonhora kutenderera.
2. Superior Wear & Erosion Resistance
Carbide inosimbaradza chikamu chine kuomarara kwepamusoro (HB 180–220) inopa kusapfeka kuri nani pane kudziya zvakajairika-masimbi asingachinji pasi pepamusoro-tembiricha yakaoma kukwesha nekukukurwa kwezvidimbu, zvichiwedzera hupenyu hwesevhisi ka2-3.
Dense surface oxide film inopa kuzvizora, kudzikisa kunamira neabrasion, yakanakira magireti, marata, mabhasikiti nezvimwe zvinopfekwa-.
3. Comprehensive Corrosion Resistance
Kuramba kwakanakisa-kupisa sarufa{{1}ine, chlorine-ine, huruva-yakatakura gasi reflue uye slag corrosion.
Inoshingirira kudzivirira-temperature oxidation, sulfidation corrosion uye erosion corrosion.
Asidhi yakanaka uye alkali corrosion resistance kune-tembiricha inoparadza zvakanyanya mumaindasitiri emakemikari nekuchengetedzwa kwezvakatipoteredza.
4. Good Casting & Machining Adaptability
Kuyerera kwakanaka kweaustenitic matrix, kuita kwakanakisa kwekukandira kwezvikamu zvakaoma senge akakosha-magireti akaumbwa nema plates akabatanidzwa.
Weldability inogamuchirika uye machinability kuitira-kugadzwa kwesaiti, kugadzirisa uye kugadzirisa.
III. Mashandisirwo Aripo (Core High{{1}Temperature & Wear-Resistant Fields)
Metallurgy & Kupisa Kurapa Indasitiri
Mafuro ekupisa kupisa: mabhasikiti echoto, matireyi, njanji yekutungamira, mahwendefa egadziko rechoto, zvindori zvekutsigira.
Heating / annealing furnaces: simbi dzechoto, zvikamu zvegonhi, machubhu anopenya, mitsetse yevira.
Simba & Boiler Indasitiri
Chiteshi chemagetsi & mabhaira emuindasitiri: magireti echoto, machira ekudzivirira{{0}machira, maramba emadziro emvura, maburi ekupisa.
Tsvina incinerators: grate mbariro, choto liners, slag discharger zvikamu.
Chemical & Environmental Protection Equipment
Makemikari ekudziisa / kutsemuka mafito: mapaipi ekupisa-akakwira, mavharuvhu, mareactor liner.
Simende & kilns yekuvaka: preheater liners, kiln inlet yekudzivirira mahwendefa, zvikamu zvinotonhorera.
Zvimwe{{0}Kupisa Kwekupisa-Zvisingachinji
Zvisiri-kunyungudutswa kwesimbi kunyungudika: marambi echoto, mbaura, hoppers.
Ceramic & kilns dzegirazi: kumusoro-kupisa kunotakura zvikamu, conveyor rolls.
IV. Kuenzanisa Kwakanakira 1.4825 Kupfuura Magiredhi Akafanana
Zvichienzaniswa ne1.4776, 1.4823 uye 1.4865, 1.4825 inomira zvakanaka-pamwero wayo wekuita zvakanaka:
vs 1.4776: Kukwirira kwepamusoro-kusimba kwehutambiricha uye kusapinda kwepamusoro-tembiricha uye kunorema{3}}mamiriro ebasa.
vs 1.4823: Zvirinani kuomarara uye kupisa kutyisa kuramba, kuderedza kupisa kuneta kuputika.
vs 1.4865: Kuwedzera kudhura-kunoshanda uku uchigutsa zvakanyanya pamusoro-maapplication ekupfeka ekushisa ari pasi pe900 degrees.
