Grate Bars-a thil awm dan:
1. MC type carbide tihchakna hmang rawh. Technical treatment zawhah chuan alloy-a MC-type carbide siamte hardness leh high-temperature stability chu traditional grate bar material-a M7C3 leh M23C6-te aiin a tha zawk a ni. Modification treatment hmang hian grate bar-a high-temperature strength leh high-temperature wear resistance te chu a tha zawk a; Chu bakah, kawng khatah chuan MC-type carbides chuan alloy-a C element chu a ei a, chromium tam zawk chu alloy matrix-ah a lut thei a, chu chuan alloy-a oxidation resistance leh high-temperature strength a ti tha lehzual a ni.
2. Rare earth leh boron hmang la, modification treatment hmang rawh. Modification treatment hnuah matrix leh carbides te chu a refined a, matrix-a carbides splitting effect chu a chak lo va, grain boundary te chu a thianghlim a, oxidation resistance, impact toughness, high temperature strength leh creep strength of the alloy te chu a tha lehzual a ni.
3. Lost foam casting process hmang hian Grate-a a lan dan leh a chhungril quality chu traditional sand casting aiin a tha zawk.
Grate bar hnathawhna hmun:
1. Temperature inthlak danglamna lian tak: Sintering lai hian sinter temperature chu 1100℃vel a ni thei a , grate temperature chu a tlangpuiin 800 to 1000℃a ni thei Unloading hnuah chuan boruak lumna chu boruakah 100-300 degree-ah a tlahniam nghal vat a ni.
2. Gas Corrosion: boruak a CO, CO2, SO2 leh water vapor te oxidation leh corrosion.
3. High-temperature load-bearing: High-temperature sintering-a sintered ore-a gravity effect chu tuar rawh.
4. Sinter-a Impact leh Friction Wear: Loading leh Unloading process chhunga sinter material-a nghawng leh friction wear.
5. Temperature sang leh chak tak powder-gas two-phase flow hmanga scouring.
