Definitions
- the present invention relates to a fine steel or Wire mill with a multi-stand roughing mill, one multi-stand intermediate street and one of 6 or 8 or 10 Roll stands equipped with a common drive Finished block.
- Prefabricated blocks usually consist of six, eight or ten Roll stands with a common drive. That’s why Speed ratios of the scaffolds with each other and with it the acceptance of the individual scaffolding.
- a modern fine steel or wire mill is to be designed that they meet current requirements Performance and product quality. From It is of existential importance to be an international to produce a competitive end product. This includes u. a. Compliance with tolerances of up to ⁇ 0.1 mm in the wire area and a high degree of flexibility when converting the Rolling program.
- DE-0 114 793 A2 discloses a roll block for high Speeds with, for example, 8 H / V stands, which to drive four groups each by two Helical gear units in kinematic connection Drive units with one engine each are assigned.
- the invention is the Task based on a constructive design of a Specify finished blocks with which the acceptance of the last two stitches can be varied so that one hand different finished dimensions of a rolled product with the rolled the same initial cross section of the upstream stands can be, and which on the other hand enables one with Cross-sectional differences emerging from the intermediate street Rolled stock in compliance with strict cross-sectional end tolerances finish rolling.
- One embodiment provides that the drive shafts of the individual drive units with the longitudinal drive shafts cross drive shafts crossing the group drive trained and over similar bevel gear with a each individually drivable roller can interact are kinematically connected.
- An embodiment essential to the invention further provides that each of the individually driven scaffolds individual drive unit, each comprising one motor, one individual gear unit and an adapter gear assigned.
- FIG. 2 shows purely schematically a rolling mill with a Billet furnace (1), a compensating furnace (2), scissors (3), a roughing mill (4) with four H / V stands (20), followed by a water tank (5) and a downstream intermediate street (6) with six individual scaffolds (21), each with separate Drive units, and this is followed by a finished block (7).
- This has eight stands (22) in arrangement with one common drive unit.
- the scaffolding (22) in Finished block (7) are arranged after two stands (23) and (24) available and according to the invention each with a Single drive (9) or (10) equipped.
- Figure 3 shows an enlarged view of the finished block (7) with the two downstream stands (23) and (24) each with a single drive (9) or (10) with their horizontal drive shafts (13) or (13 '). These cross the Longitudinal drive shafts (27, 28), which the group drive (8) of the finished block (7) are assigned.
- everyone is the one last two stands (23) and (24) an individual motor (14, 14 '), further a bevel gear unit (30, 31) and an adapter gear (12, 12 ') assigned.
- the structural design of the scaffolding (23) or (24) is in Figures 4a and 4b shown in detail. Own them preferably horizontally arranged drive shafts (13) and (13 '), which with similar bevel gear (30, 31) an individually drivable roller (32, 33) cooperatively kinematically connected.
- the driven one Rollers (32, 33) are rotating rollers (32 ', 33') in themselves assigned in a known manner.
