Khoom yam ntxwv & Castability
Superior High -Tsub Ua Haujlwm
Lub 1.4777 tshav kub-resistant steel grate exhibits zoo heev oxidation tsis kam thiab siab - kub lub zog, tswj cov qauv kev ncaj ncees txawm nyob rau hauv lub sij hawm ntev thermal raug mus txog 1100℃. The high chromium content (27-30%) promotes the formation of a dense, adherent Cr₂O₃ oxide layer that protects against scaling, spalling, and corrosive attack in furnace environments.
Castability zoo heev
Tsis zoo li ntau lub siab- alloy kub- cov hlau tsis muaj zog uas nyuaj rau deform los yog forge vim lawv cov ntsiab lus alloy siab, 1.4777 casting steel yog tshwj xeeb rau kev tsim cov khoom tsim. Casting tsis tsuas yog ua kom yooj yim grate bar geometries tab sis kuj ua rau ntau dua creep rupture zog piv rau cov sib npaug wrought. Cov txheej txheem casting muaj xws li:
- Xuab zeb casting – Nqi -zoo, haum rau loj- ntim ntau lawm
- Kev nqis peev casting (precision casting) - zoo tshaj qhov chaw tiav, nruj dua qhov ntev kam rau ua, zoo tagnrho rau intricate grate designs
Zoo Machinability & Weldability
1.4777 steel muaj qhov sib npaug hardness (∼113 HBW) uas tso cai rau cov txheej txheem machining, suav nrog drilling, sib tsoo, thiab ua tiav. Nws kuj pom zoo weldability thaum ua raws li cov txheej txheem tsim nyog, ua kom yooj yim kho thaj chaw lossis hloov cov khoom siv.
Thermal Fatigue & Thermal Shock Resistance
Kev kho cua sov kom zoo-feem ntau annealing ntawm 800-850℃kom ua tiav qhov hardness qis dua 300HB- txhim kho microstructure stability ntawm 1.4777 grate bars thiab txhim kho kev tiv thaiv thermal cycling thiab thermal shock, uas yog hom tsis ua hauj lwm hauv qhov cub grate daim ntaub ntawv.
Vim li cas thiaj xaiv 1.4777 Thaum tshav kub kub-Resistant Steel Grate?
Tus nqi zoo tshaj -Qhov Kev Ua Tau Zoo
Nrog cov ntsiab lus npib tsib xee tsawg dua los yog sib npaug li 1%, 1.4777 grate bars muaj kev ua haujlwm siab zoo heev - qhov kub thiab txias tsis muaj tus nqi hwm cuam tshuam nrog npib tsib xee- nplua nuj austenitic tshav kub- cov hlau tsis muaj zog. Qhov no ua rau lawv muaj kev xaiv pheej yig heev rau loj - nplai boiler thiab incinerator installation.
Kev Pabcuam Ntxiv Lub Neej Nyob Hauv Cov Txheej Txheem Tsis Txaus Siab
Kev sib xyaw ua ke ntawm cov ntsiab lus siab chromium thiab optimized casting microstructure ua kom muaj kev tiv thaiv zoo rau:
- High -kub oxidation thiab scaling
- Thermal cycling qaug zog
- Corrosive flue gas nres (nrog rau sulfidation)
- Abrasion los ntawm txav lub txaj roj
Cov yam ntxwv no txhais tau ncaj qha rau kev txo qis qis, txo tus nqi kho, thiab nce kev tsim khoom rau koj qhov chaw.
