Arrangement structure and arrangement method of roller ways of hot mill in aluminum plate strip hot rolling shop

Abstract

The invention relates to an arrangement structure and arrangement method of roller ways of a hot mill in an aluminum plate strip hot rolling shop. The arrangement structure comprises the hot rolling shop, a hot rolling straddle and the hot mill; the hot rolling straddle is arranged in the hot rolling shop; the hot mill is arranged in the hot rolling straddle; roller ways consisting of a pluralityof rollers are arranged at the inlet end and the outlet end of the hot mill; each roller independently carries out independent two-way driving or the rollers carry out grouped two-way driving to convey cast ingots or hot rolled plates to the hot mill in a reciprocating manner; the middle sections of the roller ways of the hot mill are arranged on the ground; each roller is parallel to the ground and the roll surface elevations of the rollers are identical; the two ends of the roller ways of the hot mill are arranged in inclined grooves underground correspondingly; each roller is parallel to the corresponding groove; the roller surface elevations are in the identical oblique line; and the slope factors of the rollers are identical with those of the grooves. The floor lengths of the roller ways of the hot mill are reduced, so that the length of the hot rolling shop is reduced, the floor area is saved, and the construction investment in a factory building is lowered.

Description

technical field [0001] The invention relates to an arrangement structure of a rolling mill roller table in a hot rolling workshop, in particular to an arrangement structure and an arrangement method of a hot rolling mill roller table in an aluminum strip hot rolling workshop. Background technique [0002] As known, a hot rolling workshop is a production workshop that provides hot-rolled slabs and coil blanks in the production of aluminum strips. Its technological process is ingot casting-milling-heating-hot rolling. The ingot will be reciprocated and transported to the hot rolling mill through the roller table for multi-pass reversible rolling before it is rolled to the coil thickness after hot rolling. Therefore, the larger the weight and thickness of the ingot, the longer the roller table. Generally, the maximum length of an aluminum processing plant depends on the hot rolling span, and the length of the hot rolling span depends on the length of the hot rolling mill roll ...

AI Technical Summary

Problems solved by technology

For the aluminum processing project of newly added hot rolling or upgrading of existing hot rolling, due to the limitation of the length of the site, the length of the roller table of the hot rolling mill cannot be satisfied, which limits its construction and implementation
