Nneɛma a ɛwɔ Grate Bars mu:
1. Fa MC Type Carbide a wɔde hyɛ mu den di dwuma. Wɔ mfiridwuma ayaresa akyi no, den ne soro-ɔhyew a ɛyɛ den a ɛwɔ MC{ 3}}Type carbide a wɔayɛ wɔ aduru no mu no ye sen M7C3 ne M23C6 de wɔ atetesɛm grate bar nneɛma mu. Sɛ wɔde nsakrae ayaresa no di dwuma a, ahoɔden a ɛkorɔn-ɔhyew ahoɔden ne-temperature wear resistance a ɛwɔ grate bar no mu no ye; Bio nso, ɔkwan baako so no, MC{11}}Type carbides di C element no wɔ aduru no mu, na ɛma chromium pii kɔ alloy matrix no mu, na ɛma oxidation resistance no tu mpɔn bio na ɛma ahoɔden a ɛkorɔn-temperature ahoɔden a ɛwɔ aduru no mu.
2. Fa Rare Earth ne boron di dwuma ma nsakrae ayaresa. Wɔ nsakrae ayaresa no akyi no, wɔyɛ matrix ne carbides no yiye, carbides no mu mpaapaemu tumi wɔ matrix no so no yɛ mmerɛw, ɛho tew, na oxidation resistance, impact toughness, high temperature strength ne creep ahoɔden a ɛwɔ aduru no mu no tu mpɔn kɛse.
3. Sɛ wode foam casting a ayera no di dwuma a, grate no hwɛbea ne ne su a ɛwɔ mu no korɔn sen anhwea a wɔde gu tete no.
Grate Bar Adwumayɛbea:
1. Ɔhyew mu nsakrae kɛse: Wɔ sintering mu no, ɔhyew a ɛwɔ sinter no mu no betumi akɔ soro akodu digrii 1100 , na mpɛn pii no, grate no hyew yɛ digrii 800 kosi 1000 ; Sɛ woyi fi mu wie a, ɔhyew no so tew ntɛmntɛm kodu digrii 100-300 wɔ mframa mu.
2. Gas corrosion: oxidation ne corrosion a ɛwɔ CO, CO2, SO2 ne nsuo a ɛyɛ hyew wɔ wim.

4. Nkɛntɛnso ne friction wear of Sinter: Impact ne friction wear a ɛwɔ sinter nneɛma mu bere a wɔde nneɛma gu mu ne nea wɔde gu mu no.
