在模拟造纸机烘缸实际冷却条件的情况下，研究了Ｓｉ／Ｃ，Ｃｒ，Ｃｕ，Ｍｎ对高Ｓｉ／Ｃ比铸铁性能的影响，提出了一种高强度、高硬度的高Ｓｉ／Ｃ比铸铁替代原用合金铸铁来生产烘缸．
The effects of Si / C, Cr, Cu, Mn on the properties of high Si / C cast iron were studied under the conditions of the actual cooling conditions of the paper machine dryer. A high Si / C ratio Cast iron instead of using the original cast iron to produce dryer.
