Grey Cast Iron Grate Bar EN-GJL-200
A grate bar refers to a series of strip holes in a combustion equipment opened by many air vents or combustion frequencies, usually made of metal materials, which can withstand constant high temperatures. The grate strip is usually located at the bottom of the furnace, can also be on the side or upper part of the combustion chamber, its role is to allow the gas and solid fuel through, promote the combustion reaction.
Heat Resistant Steel Intermediate Grate SCH11
Heat Resistant Steel Intermediate Grate Sch11 Heat resistant steel intermediate grate SCH11 Is one of the main grate strip products we produce, using precision casting process, manufacturer direct sales, excellent material, quality assurance, diverse specifications, welcome customization.
High Chrome Cast Steel Grate Bar
High Chrome Cast Steel Grate Bar is high quality and strong furnace strip, its production process is more complex, the cost is high, suitable for high temperature furnace. The advantages of steel grate are high strength, heat resistance, corrosion resistance, not easy to deformation, long service life.
Sinter Grate Bar
The grate strip is usually made of superalloy material and has extremely high wear and heat resistance. This material can maintain stable performance in high temperature environment, while can resist the wear of materials in the furnace and corrosion of high temperature gas. The grate strip is usually designed with a special structure to enhance its wear resistance and extend its service life.

● Erosion of high temperature and high speed powder-gas two-phase flow.
● Corrosion: Oxidation and corrosion of CO, CO2, SO2 and water vapor in the atmosphere.
● Large temperature changes: During sintering, the temperature of the sintered ore is as high as 1100℃, and the temperature of the grate is generally 800-1000℃, after unloading, the temperature in the air drops rapidly to 100-300℃.
● Impact and friction and wear of sintered ore: Impact and friction and wear of sintered ore during loading and unloading;
● High temperature load-bearing: Bear the gravity of sinter during high temperature sintering.
