| description | The utility model relates to a production system for a non-quenched and tempered ocean engineering structure pipe at the steel grade being higher than 360MPa. The production system comprises a heating furnace, a cone mill, a periodic tube mill, a heat insulation temperature raising device, a two-roller conical roller inclined mill and a cooling bed, wherein the heating furnace, the cone mill, the periodic tube mill, the heat insulation temperature raising device, the two-roller conical roller inclined mill and the cooling bed are in sequential arrangement, and in addition, the adjacent devices are connected through transmission rollers or cranes. Compared with the traditional off-line modulation heat treatment process, the production system has the advantages that the heat mechanical control milling non-quenched and tempered processing process is adopted, the heat treatment work procedure cost can be effectively reduced, and the productivity can be greatly released. |
