In the prior art, known have six-high cluster mill rolled band steel, roll layout arranged vertically.These milling trains can carry out roller to working roll, and intermediate calender rolls is carried out roller and roll shifting, and simultaneously working roll and intermediate calender rolls are carried out roller and roll shifting, utilize these technology controls with quality and the plate shape of steel.But these milling trains all can not use major diameter backing roll and the working roll of minor diameter very, can not prevent the flexure unber lateral of working roll.If use the very little working roll of diameter, then need to be equipped with the milling train of more branched runner, for example mkw mill, twelve high mill or mill.Increasing of roll quantity brought that roller system is complicated, spare parts management is difficult and the shortcoming of inconvenient maintenance.
The problem that prior art need to solve is: can use the large backing roll of major diameter rigidity, and suitable minor diameter working roll, work that can be highly stable, working roll can flexure unber lateral.In the situation of equal roll-force and roll torque, reduce the contact stress between working roll and the backing roll, improve the efficient of rolled plate.Therefore, need a kind of modified milling train of development, it is compared with the milling train that roller system is arranged vertically type, in the situation that adopts equal reduction ratio and drafts, can reduce draught pressure and roll torque, prevent the appearance of surface of steel plate transversal wave movement line, improve plate surface quality, steel plate that can be rolling hard and thin improves rolling efficiency.
Summary of the invention
The purpose of this utility model provides a kind of improved card roll-type six-high cluster mill, it has solved the backing roll that six-high cluster mill in the past can not use major diameter large rigidity, can not use suitable minor diameter working roll, working roll produces flexure unber lateral, roll-force and roll torque are large, contact stress between working roll and the backing roll is large, the problems such as steel plate that can not be rolling hard and thin.
Technical solution of the present utility model is as follows:
A kind of card roll-type six-high cluster mill, it comprises upper roller system and lower roll system, described upper roller system is comprised of two major diameter tops backing up roll and a minor diameter top working roll, above wherein two major diameter tops backing up roll are positioned at, minor diameter top working roll centre position below two major diameter tops backing up roll;
Described lower roll is to be comprised of a minor diameter bottom working roll and two major diameter lower support rolls, below wherein two major diameter lower support rolls are positioned at, and minor diameter bottom working roll centre position on two major diameter lower support rolls;
Described top working roll and bottom working roll are oppositely arranged.
Described two tops backing up roll and two lower support rolls are installed in the solid housing respectively.
Described top working roll and bottom working roll are installed in the bearing block respectively.
The diameter range of described top backing up roll, lower support roll is Ф 300 ~ Ф 1500mm.
The diameter range of described top working roll, bottom working roll is Ф 80 ~ Ф 700mm.
Use card roll-type six-high cluster mill of the present utility model, can reduce the milling train height, adopt leg-of-mutton stability principle, use the arrangement of minimum roll, prevent the working roll flexure unber lateral, realize stable rollingly, and reduce roll-force and roll torque, steel plate that can be rolling hard and thin improves rolling efficiency.
Use card roll-type six-high cluster mill of the present utility model, can also reduce bending roller force, simplify frame for movement, alleviate machinery wieght, reduce the pressure of hydraulic system.
