Example Embodiment
[0030] Example 1
[0031] This embodiment provides a high-strength corrosion-resistant cold rolled steel roll, which includes the following components: C: 0.15%, Si: 0.1%, Mn: 0.025%, P: 0.020%, S: 0.010%, ALS: 0.02%, Ti: 0.025%, Cu: 0.1%, CR: 0.3%, V: 0.01%, the rest is iron and inevitable impurities.
[0032] The above-mentioned production method of the above high-strength and corrosion-resistant hot rolled steel roll includes the following steps:
[0033] 150 tons of converter vanadium, 150 tons of converter smelting, LF refining, a slab having a thickness of 200 mm;
[0034] The slab is placed in the heating furnace, the heating time is 120 min, the heating temperature is 1200 ° C;
[0035] After the slab is released from the heating furnace, the pressure of 20 MPa is removed by a high pressure water deficiency of 20 MPa;
[0036] Then, the slab was rolled by the thick rolling mill, and the rough rolled rolled outlet temperature was 1040 ° C;
[0037] Then, the slab is passed ...
