Zusammenfassung: | A roll assembly for rolling special-shaped steel, comprising: an upper roll (5), a lower roll (6), a left roll (9), and a right roll (8). The left roll has a left forming surface (7), the right roll has a right forming surface (81), the upper roll has an upper forming surface (51), and the lower roll has a lower forming surface (61); the left forming surface, the right forming surface, the upper forming surface and the lower forming surface together enclose a cavity; the upper roll and the lower roll can respectively move in an up-down direction; the left roll and the right roll can respectively move in a left-right direction. Also disclosed is a rolling mill train. The rolling mill train comprises at least two rolling mills; each rolling mill comprises a stand and a roll assembly provided on the stand; the roll assembly can be applicable to special-shaped steel similar in shape but different in size; moreover, when a cavity wall of the cavity is worn, on-line compensation can be implemented without stopping production and disassembling rolls. Thus, the production efficiency is ensured, and the purchase cost of rolls is saved. |
