Abstract
Disclosed is a milling device for inline-rolling a steel band which is produced especially by means of a twin-roll continuous casting process. Said milling device comprises at least two rolling units (20, 30) with working rolls (21, 31) that mill the steel band (11) and support rolls (22, 32) which support said working rolls. The working rolls and support rolls are rotatably mounted in bearing housings (23, 24, 33, 34). At least two rolling units (20, 30) are disposed successively in a monolithic or multipiece frame structure (15) such that the rolling temperatures between the rolling units differ only slightly while a simple and inexpensive design is created.

Rolling device for inline-rolling a steel band, which has at least two rolling units (20, 30) with working rolls (21, 31) to mill the steel band (11) and support rolls (22, 32), rotatably mounted in bearing housings (23, 24, 33, 34), wherein each of the two rolling units (20, 30) comprises upper and lower working rolls (21, 31) located above and below, respectively, a space through which the steel band (11) passes and upper and lower support rolls (22, 32) rotatably connected with the upper and lower working rolls respectively, the working and support rolls in each of the two rolling units being located with their axes of rotation in a respective, common plane (20′, 30′) running perpendicular to an extension of the steel band (11), further comprising:
- a frame construction (15) in which the at least two rolling units (20, 30) are arranged directly in series;
- bearing housings (23, 24, 33, 34), each working roll (21, 31) and the support roll (22, 32) rotatably connected thereto being rotatably mounted on each side in a respective one of the bearing housings (23, 24, 33, 34);
- and
- drive systems that adjust a height of the bearing housings (23, 24, 33, 34) such that each working roll (21, 31) and the support roll (22, 32) rotatably connected thereto and rotatably mounted on each bearing housing (23, 24, 33, 34) are moved together by the drive system that adjusts that bearing housing (23, 24, 33, 34).
