ABSTRACT:
In a system and method for manufacturing thin plate by hot-working, a splicing machine for continuously splicing the front edge of a following plate and the rear edge of a precedent plate is provided in the process precedent to a set of rolling mill stands having non-driven small diameter working rollers. By continuously splicing the plates, most portions of the rolled plates can be rolled under a steady state rolling condition, that is, an after-engaged rolling condition, and the thickness reducing amount of the plates in most portions of the rolled material is substantially increased, which substantially improves the rolling efficiency. Thereby, the diameter of the working rollers can be decreased smaller than the diameter of working roller used in a conventional rolling mill, rolling mill strands can be made small, and it can be realized to attain a small-scale system for manufacturing thin plate by hot working.
