The effect of C and Si content on mechanical property of low carbon cold-rolled steel(/% :0.0051 ~0.0344 C
0.008 ~0.054 Si
0.28 ~0.30 Mn
0.023 ~0.026 P
0. 004 - 0.007 S. 0.044 ~0. 060 Al)has been studied. Industrial process is hot metal pretreatment-80tBOF-RH-continuous casting - hot rolling-acid pickling-cold rolling. Results show that the higher the C or Si content
the higher the strength and hardness
the lower the elongation. Cold rolling test was carried out in the laboratory
the test material was low carbon steel hot rolled (/% :0.0112C
0.009Si
0.30Mn
0.025P
0.006S
0.052Al) which produced in plant. Results of cold rolling test show that when the cold rolling reduction ratio increases from 41% to 57%
strength and hardness gradually increase
the elongating slightly elevate
When the content of C was 0. 005% ~ 0. 010%
Si was ≤0.012% and cold rolling rate was 40% ~ 50%
the tensile strength (Rm) of cold rolled sheet was less than 660 MPa and hardness (HRB) was 86 - 89. meeting technical requirement.
