According to the requirements of 200 mm extra thick 12Cr2MolR steel plate for hydrogen chemical industry i. e.P ≤0.007%
Si≤0. 1%
brittleness index J
≤100
X≤10x10
-6
by the electroslag remelting technology of 120 t BOF-LF-VD-continuous bloom and the heat treatment process control of 300 mm thick plate quenching machine
the extra thick 12Cr2Mo1R steel plate with thickness of 200 mm is successfully developed. The steel plate has good comprehensive mechanical properties and internal quality to meet the requirements of design technical conditions.
