Abstract
The present disclosure provides systems and methods for in-line thermal flattening and enameling of steel sheets. The systems and methods include an in-line thermal flattening of a feed stock steel sheet and a subsequent enamel coating of the steel sheet. The resulting enamel coated steel sheet has improved flatness compared with other coated steel sheets that are enamel coated but do not undergo the in-line thermal flattening. The systems and methods allow the use of less expensive source materials without sacrificing quality in the finished enameled product.
