镜面辊的保养方法：

The maintenance method of the mirror roller:

1、辊坯选用专业入口合金钢，凭据差另外材质特性，计划差另外流道布局情势；

1, the choice of professional imported alloy steel roller billet, according to the poor material characteristics, poor layout of the layout of the flow path;

2、镜面辊通常都是选用钢、合金钢无缝管、精锻件等质料，辊筒外貌光洁度可以到达光洁度14级；

2, mirror roller is usually selected steel, alloy steel seamless pipe, precision forging and other materials, roller appearance smooth finish can reach 14 level of finish.

3、可以在各种材质的外貌进行镜面加工，能确保辊筒外貌的平直度、均衡度、不圆度、同轴度等到达要求；

3. Mirror processing can be done on the appearance of all kinds of materials. It can ensure the flatness, balance, roundness and coaxiality of roller appearance.

4、镜面辊冷却或加热温差不大于1℃，外貌硬度HRC55～58，镀铬抛光后硬度HRC62，热变形不大于0.01mm。

4. Mirror roller cooling or heating temperature difference is not greater than 1 degrees C, appearance hardness HRC55 ~ 58, chrome plated after polishing hardness HRC62, thermal deformation is not greater than 0.01mm.
