Description
Technical field
The invention discloses a kind of mill housing, the mill housing of especially a kind of gap that can disappear with short-stress path.
Background technology
Mill housing is the supporter of back-up roll two end axles bearing in the pole piece operation of rolling, in existing mill housing
" mouth " font that portion's structure is mainly made up of two root posts and crossbeam, bottom girder, Chinese patent CN105032938A discloses one
Plant the mill housing of hollow structure, retain crossbeam, two columns and bottom girder are partially fabricated the U-shape structure of one, so that
Die change in memorial archway is more convenient, but for the larger milling train of roll-force, the stress suffered by " mouth " font milling train is excessive, that is,
Line of tension is long, so that memorial archway rigidity substantially reduces.
In the installation process of milling train, mill housing and bearing block can there is gap, mill housing gap is equipment essence
The chief component of degree management, directly influences the stability of milling train.Gap is excessive, leads in top working roll and bottom working roll
Heart line shifts so that actual roll-force and roll gap change, and can have a strong impact on the rolling accuracy of milling train.For example China is special
A kind of mill housing gap adjustment compensation device is refer to, with displacement sensor activity liner plate in sharp CN204912282U
Change in displacement, then the movement of oil cylinder control activity liner plate, precise control mill housing gap is adjusted by gap.But this inter-species
Clearance adjustment apparatus, using displacement sensor, then are adjusted by hydraulic cylinder, and mill housing overall cost cost is too big,
No too many practical value, cost performance is extremely low.
Therefore provide a kind of structure simple, reasonable stress, line of tension is shorter and mill housing of the gap that can disappear becomes existing
Problem demanding prompt solution in technology.
