Mining wheel rimsmankimey ed silong na graben kondisyon na trabaho: ambelat ya ag-onkukurang a karga, tuloytuloy ya impaka-epekto na ag-apantay a tapew na karsada na minahan, abrasive friction ed saray piraso na bato tan mabetbet a cyclic stress. No anggapoy suston heat-treatment, saray forged steel rims et mainomay ya naderal so surface wear, fatigue crack, permanentin deformation tan biglan fracture, ya pansengegan na magastos ya downtime tan safety hazards na saray kagawaan ed panagmina.

860-920 degree |
1.5-3 h |
Pinoen so istruktura na bukel, gawaen ya parepareho so metal ya walad loob, ekalen so stress ed panag-cast/forging |
Paaligwasen so inkapekder na materyal, paabebaen so depekto ed loob; mangiletneg na malet a pundasyon parad ontumbok ya pamaawet |
Ag-inkaparpareho na inka-malet, nakekeraan ya stress ed panag-forge, masakbay ya inggapo na bitak ed silong na ambelat ya epekto |

Panerep |
840-900 degree, water/oil quenching |
1-2.5 h |
Maples ya pan-cool pian naporma so martensite ya istruktura, napaatagey so tapew tan say core |
Pabiskegen so resistensya ed panag-usar tan say pakayarin mangawit na karga sumpad pan-apag-apag na graba ed mina |
Maples ya pan-abrase na tapew, pan-deformate na rim diad silong na ambelat ya panagmina |
|
Tempering (Medium-High) |
480-620 degree |
2-4 h |
Ibulos so ag-inkayadyari, balanseen so inka-malet tan inka-malet na impaka-impake |
Naprebentaan so ag-onkupas ya pan-break ed silong na mabetbet a shock load ed saray maruksan minaan ed silong na dalin |
Quench-induced internal cracking, biglan inkagba na rim legan na impaka-impake |
|
Panagpaawet ed tapew (Panagpaawet na Induction) |
880-950℃(local heating) |
0.2-0.8 h (local) |
Pabiskegen labat so contact-wear surface; pansiansiaen ya malet so loob na rim matrix |
Say atagey ya wear-resistant ed paway ya tapew legan ya mansiansia so shock-absorb ed loob na laman |
Maples ya pan-upot na ulpo, pan-seal-personal ed tapew, pinatikeyan so serbisyo |
Say heat treatment so sankaepektiboan a paraan na metalurhiya pian na-adjust so internal microstructure na wheel-rim steel, imbes ya umanen labat so sukat na paway. Kada kundang na panagpainit tan panagpabetel et manpupuntirya ed saray espisipikon makapuy a punto na saray rim na panagmina.
Say pangi-normalize et mangekal na ag-inkaparpareho na ilik ya sengegan na mainit ya forging. Kayari na panag-forge, saray metal ya bukel et ag-ontutundan ombaleg. No painitan ed niletneg ya temperatura tan matantan ya palemewen, saray ilik et magmaliw ya pino tan parepareho, kanian say stress et ag-onsentro ed saray partial weak zones no say rim et walaan na baleg a belat na panagmina.
Say pangi-quench et mamaaligwas a maong ed inka-malet. Say proseso na maples ya panagpalemew et mangi-lock ed saray malet ya istruktura na kristal ed loob na asero, kanian say rim et mas makaresisti ed saray abrasive scraping manlapud saray ores tan saray matalimbeng a debris na mina.
Say atagey ya temperatura na panag-inom kayari na panag-erep et importante. Say asero ya naerep et magmaliw ya malet balet ta maples ya onkupas. Say panag-tempering et mangibulos na internal quenching stress tan mansasaliw na partial hardness parad ekselentin impact toughness. Sayan kablian so mamatunda ed rim ya ag-onkapuy no onsabi ed saray abot ed saray tunnel ed silong na dalin odino diad saray open-pit mines.
Say lokal ya induction surface hardening et mangiyoopresi na solusyon. Say high-wear contact area labat so onkakasil, bangta say manunan laman na rim et mansiansian malet. Sayan desinyo et mamapaliis ed kaslakan a depekto: saray rim ya alablabas so laman na laman et mainomay ya nabuyak no grabe so impaka-shock to.
Diad kompleton heat-treatment workflow, asumpalrim na pilid na panagminamakagamor na mas andukey a bilay, mas abeba so ag-iilaloan ya ag-inkayadyari tan mas maong ya adaptasyon parad andukey a panaon ya transportasyon na ambelat a panagmina.
