<p>Method to make long metal rolled products comprising the following steps:
- continuous casting at high hourly productivity, from 35 t/h to 200 t/h, done by a single casting machine (11), defining a casting axis, of a product with a rectangular or equivalent section, with a ratio between the larger side and the smaller side higher than or equal to 1.02 and less than or equal to 4;
- shearing to size of the cast product to define a segment of a length comprised between 16 and 150 m and with a weight comprised between 10 and 100 tons ;
- introduction of the segment, having an average temperature of at least 1000°C, into a maintenance and/or possible heating furnace (14), comprising a first section (20a) for moving the cast product disposed in axis with the casting axis;
- lateral transfer of the segment inside the furnace (14) in order to dispose it in a second section (20b) for moving the cast product disposed parallel and misaligned with respect to the first movement section (20a) and aligned with a rolling axis parallel and offset with respect to the casting axis;
- reduction of the section in a rolling mill (16) defining the rolling axis.</p> |
