Rolling production line

Abstract

The invention discloses a rolling production line. The rolling production line comprises five modular rolling mills which are sequentially arranged in the rolling direction, wherein each modular rolling mill comprises a transmission box (45), the transmission boxes (45) are connected with a first rolling roll box (46) and a second rolling roll box (47), the first rolling roll box (46) comprises a pair of first rolling rolls (461), and the second rolling roll box (47) comprises a pair of second rolling rolls (471); and a rolling hole formed by the pair of first rolling rolls (461) is oval, a rolling hole formed by the pair of second rolling rolls (471) is round, and the first rolling roll box (46) and the second rolling roll box (47) are sequentially arranged in the rolling direction. The modular rolling mills in the rolling production line are mutually independent and can be independently controlled, so that flexible production of the rolling line can be realized, idle rolling of the rolling mills in an empty pass is avoided, the production cost is reduced, and the production efficiency is increased.

Description

technical field [0001] The invention relates to the field of metal bar and wire rolling equipment, in particular to a rolling production line. Background technique [0002] The finishing rolling area of ​​the existing wire rod or high bar production line mostly adopts the finishing rolling unit with centralized transmission. The sorties are rolled. [0003] Take a typical 10-pass finishing mill as an example (see figure 1 ), the finishing rolling line is mainly composed of 10 rolling mills, a speed increaser 111, a coupling 112 and a main motor 113. Along the rolling direction A, the ten rolling mills are the tenth rolling mill 110, the ninth rolling mill 19, the eighth rolling mill 18, the seventh rolling mill 17, the sixth rolling mill 16, the fifth rolling mill 15, and the fourth rolling mill. The stand rolling mill 14 , the third rolling mill 13 , the second rolling mill 12 and the first rolling mill 11 . [0004] The pass numbers corresponding to the first rolling m...

AI Technical Summary

Problems solved by technology

[0014] 3. Since the rolling mill in the empty pass is centralized transmission, the rolling mill must run idling together, which increases the loss of equipment, increases the consumption of equipment spare parts, and also increases power consumption

[0015] 4. Due to the centralized transmission, the mechanical speed ratio between the rolling mills is fixed and cannot be adjusted, so the roller ring needs to be replaced when a certain pass wears out.
