Abstract
Provided are a dehydrogenation apparatus, a steel sheet production system, and a method of producing a steel sheet capable of producing a steel sheet having excellent hydrogen embrittlement resistance without changing mechanical properties of the steel sheet. The dehydrogenation apparatus includes a housing that accommodates a steel sheet coil of a steel strip coiled into a coil shape, and a magnetic field applying apparatus that applies a steady magnetic field along the sheet transverse direction of the steel sheet coil in the housing.
Claims27
A dehydrogenation apparatus comprising:
- a housing configured to accommodate a steel sheet coil obtained by coiling a steel strip;
- and
- a magnetic field applying apparatus configured to apply a steady magnetic field along the sheet transverse direction of the steel sheet coil in the housing.
A dehydrogenation apparatus comprising:
- a payoff apparatus configured to uncoil a steel sheet coil to feed a steel strip;
- a sheet passing apparatus configured to pass the steel strip therethrough;
- a coiling apparatus configured to coil the steel strip;
- a magnetic field applying apparatus configured to apply a steady magnetic field along the sheet transverse direction of the steel strip to the steel strip being passed through the sheet passing apparatus.
