We are glad to supply grate bar , produced by patent technology , consist of Cr, Mo, Al, V, Re ... etc.
The grate bar be used widely in sintering machines in China, working life time reach 12 ~ 36 months .
Related test result as below,
Test result of mechanical property at 22 ℃ and 900 ℃
Test result of mass loss after sintering period of 6 months
After sintering period of 6 months, the grate bar middle thickness lose 5.48% ,
Suppose, when its thickness-loss reach 30%, the worn grate bar need to be replaced .
Then the estimated working life time is 6 x 30% / 5.48% ≈ 33 months .
