| 摘要 |
This application discloses heating apparatus and method of heating employing longitudinally extending heating plates which maintain contact proximity with both surfaces of a line of billets at all times, i.e., actual surface contact with both sides of the billets or full surface contact with the lower side and close proximity at the upper side for engaging projecting portions if warped or burred, the plates being provided with a coating of a material having a low coefficient of friction, such as a fluorocarbon polymer, and means for advancing the line of billets along between the heating plates while the space between plates is maintained constant. |
