Working Rolls
Sendzimir mill, also known as 20-roller mill, is widely applied to cold rolling. Due to the tower layout of the roll system, the roll system has good rigidity. Because of small diameter of the work roll, it is mainly applied to rolling of difficult-to-form metal such as stainless steel, silicon steel and alloy steel, and thin strip steel (0.001mm). 96% of stainless steel strip is made by this kind of rolling mill.
Description
Applicable Roller | Material | Hardness | Material Properties |
Work roller | Cr12MoVCo D2(12%Cr tool steel) | 60-64 HRC | It is applicable to the common work roll due to the excellent wear resistance. |
Work roller | M1 M2 M7 M42(high-speed steel) | 63-67HRC | The more beautiful and thinner steel plate, stronger wear-resistance and higher thermal shock resistance. It is used for rolling of BA plate. |
Intermediate roll | D2(12%Cr) | 58-62 HRC | Peeling or crack is caused by higher hardness of roller due to high thermal shock resistance. |
Intermediate roll | Cr8(8%Cr) | 62-65HRC | Peeling or crack is caused by higher hardness of roller due to high thermal shock resistance. |
Intermediate roll | H12 A8(modified)5%Cr | 58-62HRC | Peeling or crack is caused by higher hardness of roller due to high thermal shock resistance. |
