Heat Resistant Steel Grate Bar for Machinery Parts is the first accessory of sintering trolley. The effect of high chromium furnace castbar is to form a groove space with the trolley plate. The touch part of the castor bar and the ore is the upper surface, and the two ends of the castor bar are stressed at the upper end of the ground, playing a supporting effect. The bottom of the castor bar has two effects. First, it is fixed the effect of the castor bar when turning the unloading, so that it cannot fall; second, the effect of supporting the top of the castor bar, which can prevent the twists and turns.
Working environment of the grate strip:
1. Large temperature change: during sintering, the temperature of sinter can be up to 1100 degrees Celsius, and the temperature of the grate strip is generally 800 to 1000 degrees Celsius; after unloading, the temperature in the air drops extremely rapidly to 100-300 degrees Celsius.
2. Gas corrosion: the oxidation, corrosion of CO, CO2, SO2 and water vapor in the atmosphere.
3. High temperature bearing: high temperature sintering under the sinter gravity effect.
4. Impact and conflict wear of sinter: impact and conflict wear of sinter ore in the process of loading and unloading.
5. High-temperature and high-speed powder-gas two-phase flow erosion.
Chain grate boiler is a horizontal three return water and fire pipe mixed boiler, a bunch of thread smoke pipe arranged in the pot. The left and right sides of the furnace are equipped with light pipe water cooling wall. The light chain grate is used to realize mechanical coal addition, equipped with blower, induced draft fan for mechanical ventilation, and equipped with scraper type slag discharge machine to realize automatic slag discharge. The front and rear arches of the furnace adopt the new energy-saving technology furnace arch. After the fuel falls from the coal bucket to the grate and enters the furnace, the flame reacts through the rear arch upward through the burning chamber on both sides of the body to the front smoke box, then turns from the front smoke box back to the tube in the pot, through the rear smoke box into the economizer, and then flows from the induced draft fan through the flue to the atmosphere.
