用新型高铬铸铁Cr26Ni替代Cr26Mo2Nil制造炉篦条,消除了篦条表面热疲劳开裂及台车开裂倾向,产品成本每吨下降4500元,使用寿命从非高铬材质的3~6个月提高到2年以上.
Replacing Cr26Mo2Nil with new high-chromium cast iron Cr26Mo2Nil to produce grate bars eliminates the thermal fatigue cracking and cracking tendency of grate bars. The product cost is reduced by 4,500 yuan per ton, and the service life is increased from 3 to 6 months for non-high-chromium materials to 2 years or more.
