Product Name: Grating Bar for Furnace Tools Model NO.: as customer requirement Type: Furnace Heat Pipe Range of Applications: Industrial Fuel: Gas Surface Treatment: Painted Customized: Customized Certification: ISO Trademark: FANGLE Transport Package: Woodern Case Specification: Cr26 high chromium heat resistant cast iron Origin: China Product Description Grate bar is the main part of the sintering machine on the platform, the role of the grate is to form a trough with the platform rail space, to accommodate, bearing ore.Grate and ore contact part is the upper surface, the upper two ends of the grate stress, play a supporting role.The bottom of the grate has two functions, the first is to fix the function of the grate in the turnover unloading, so that it can not fall off;The second is in the case of the top of the grate pressure plays a supporting role, the disappearance of the process grate, can effectively prevent the grate bending.The surface of the grate should directly contact the grate of heat-resisting steel with the high-temperature sinter of heat-resisting steel grate at about 1300 ºC.The working life of ordinary grate is 90-180 days.Cr react with the oxygen in the air, in the grating bar surface generates a dense layer of oxide film, which prevents the further oxidation of grating bar, eliminate the fatigue cracking and cracking tendency of vehicle, but it's prone to creep for Cr in high temperature environment, in order to improve the strength of the bar grating and corrosion resistance, and to optimize its composition design, add Ni, Mo, V and so on alloy elements, developed a new type of heat-resisting, high strength bar grating.Compared with the heat-resistant iron, the service life of the high chromium alloy bar grating is increased by three times, the cost is reduced by more than 20%, and the service life is increased from 90~180 days of non-high chromium material to more than 2 years.Main chemisrty of Cr26 high chromium heat resistant cast ironC: 1.80%--2.80%;Mn: 0.5%--2.0%;Si: <1.2%;Cr: 22%--28%;P: <0.1%;S: <0.06%We can also produce Cr26 or Cr28 cast steel , and Cr16 or Cr23 cast iron material grating bar.
