1. Hnav-Tshuaj tiv thaiv rau Ribbons
Hardfacing ntawm Edges: Deposit hard alloys (piv txwv li, siab -chromium, tungsten carbide) ntawm cov npoo sab nrauv thiab phab ntsa- sib chwv cov npoo ntawm sab hauv / sab nrauv. Qhov no boosts abrasion kuj los ntawm3–5×rau cov ntaub ntawv nyuaj (xws li slag, quartz xuab zeb).
Thickened Base Khoom: Siv thicker, siab -qib steel (xws li, Hardox) rau ribbon fabrication los tiv thaiv thinning.
Tshem Tawm Hnav Strips: Bolt hloov tau siab -manganese lossis chromium-carbide daim hlau ntawm ribbon sab nrauv rau kev saib xyuas yooj yim.
Thermal Txau: Siv tungsten carbide lossis Stellite txheej ntawm HVOF los txhim kho qhov tawv tawv.
2. Kev tiv thaiv rau lub ntsiab ncej & pob qij txha
Txhim kho Weld Roots: Ntxiv hnav-cov khaubncaws sab nraud povtseg ntawm ribbon-rau- ncej txuas los tiv thaiv kev tawg.
Hardened Ncej Tes Tsho: Nruab tungsten carbide los yog lub tes tsho Stellite ntawm cov chaw foob kom txo tau cov ntawv sau.
Cua -Purge Seals: Siv lub caj pas ntsaws ruaj ruaj nrog10-15 psicompressed cua kom tshem tawm cov khoom los ntawm cov thawv ntim khoom.
3. Liner & Trough Wear Control
Hloov tau Liners: Kab trough phab ntsa / hauv qab nrog bolted siab -manganese lossis chromium-carbide daim hlau kom cais kev puas tsuaj.
Welded Grid Patterns: Hardface trough interiors nrog crisscross weld qauv los tiv thaiv yaig.
Precise Gap Control: Khaws3-5 hliQhov sib txawv ntawm ribbons thiab liners kom tsis txhob muaj cov khoom ntxiab los yog khawb.
4. Txheej Txheem & Kev Ua Haujlwm Zoo
Lower Peripheral Ceev: Txo ribbon ntsis ceev (feem ntau1.5–2.5 m/s) kom txo qis kev sib txhuam siv.
Kev tshem tawm txawv teb chaws: Nruab cov hniav nyiaj hniav kub kom tsis suav cov hlau / cov khoom seem uas ua rau muaj kev puas tsuaj.
Khoom siv ua ntej: Tshuaj ntsuam los yog crush oversized / tawv hais; tswj cov dej noo kom tiv thaiv adhesion.
Tsis txhob overloading: Ua haujlwm ntawm70–80%muaj peev xwm txo torque thiab kev sib cuag siab.
5. Lub Sijhawm Saib Xyuas Kev Tiv Thaiv
Txhua hnub: Tshawb xyuas ribbon rau khoov / tawg; tshawb xyuas cov ntsaws ruaj ruaj rau cov xau; mloog cov suab nrov txawv txav.
Txhua hli: Ntsuas ribbon thickness (hloov yog hnav>1/3thawj); txheeb xyuas bolt nruj.
Peb lub hlis twg: Realign ncej; tshuaj xyuas cov roj gearbox; ntxuav trough kom huv si.
Txhua xyoo: Rov tsim cov khoom hnav; rov siv cov txheej txheej hardfacing.
