摘要根据傅里叶定律、牛顿冷却定律以及辊式破碎机辊轴的有关参数建立了辊轴的热传导模型，模拟计算了不同工况下的辊轴使用情况。在600℃工况温度时，辊轴采用风冷、使用40Cr材料可以安全使用；但在850℃工况温度时，辊轴材料需更换为0Cr18Ni9，或辊轴材料不变，冷却方式改用水冷，方可满足使用安全。

Abstract: According to Fourier's law, Newton's cooling law and the relevant parameters of the roller shaft of the roller crusher, the heat conduction model of the roller shaft was established, and the usage of the roller shaft under different working conditions was simulated and calculated. At 600 ℃ operating temperature, the roller shaft was air-cooled and 40Cr material could be used safely. At 850 ℃ operating temperature, the roller material was changed to 0Cr18Ni9, or the roller material remained unchanged, for the cause of safety, the cooling method must be changed to water cooling.

Key words: grate cooler high temperature roller crusher roller shaft
