Lost Foam Cast Grate Bars

Fly foundry supply various grate bars made in lost foam casting processs in China. 

Grate bar is the important component for sintering furnace buidling. Grate bars are fixed onto sintering furnace as the support structure to 
support the mine coal materials. 

Grate bars work in high temperature environment. So, the material required to cast the grate bars are heat resistant materials, such as high chrome steel, high chrome irons, etc. Mostly used high chrome steel or high chrome iron grades are DIN 1.4776、DIN 1.4777、GX350、Cr13、Cr15、Cr18、Cr20、Cr26Ni1、Cr25、Cr27、Cr15Mo1、Cr18Mo1、Cr26Ni4, ASTM A297-H.I. If you have special material requirements on your grate bars, please advise. The grate bars can also be customed. 

Currently, the grate bars can be casted in processes of lost foam casting, lost wax casting and precoated sand casting. Here, we use lost foam casting process to make this type of sintering furnace grate bars. The structure can be simple and complex.
