在热轧过程中，表面氧化层、氧化皮可能会影响摩擦力并影响轧制特性。含硅钢在氧化后在 1273 K 至 1473 K 之间轧制 0 s 至 40 s，压下量为 30%。在含硅钢中，氧化皮中形成Fe 2 SiO 4 ，并在1450 K引起FeO之间的共晶转变。轧制力受氧化皮共晶转变的影响。如果轧制温度略低于共晶温度，则轧制力分散并且板材发生卷曲。这是由于转变导致液相形成不均匀。
In hot rolling processes, surface oxide layer, scale, may influence friction and affect rolling characteristics. Si-bearing steel was rolled between 1273 K and 1473 K after oxidation for 0 s to 40 s at a reduction of 30%. In Si-bearing steel, Fe 2 SiO 4 is formed in the scale and causes eutectic transformation between FeO at 1450 K. The rolling force is affected by the eutectic transformation of the scale. If the rolling temperature is just below the eutectic temperature, roll force scatters and curling of the sheet occurs. This is due to inhomogeneous formation of the liquid phase because of the transformation.
