Machine.
Background technique
The roller system of band mill can be divided into vertical roller system and tower rollers system according to the shape between roll axis.
There are duo mill, four-high mill and six-high cluster mill etc. in vertical roller system.It is wide since roll gap opening degree is changeable
It is general to be applied to hot rolling and cold rolling；Wide and Thick Slab hot-rolling mill is almost four-high mill, if the widest 5.5 meters of milling trains in the world are exactly four-roller
Milling train.
Tower rollers system has tower-shaped six-high cluster mill, twelve high mill, mill and tower-shaped six-high cluster mill to derive from
Mkw mill etc..Since multi-roll mill roll gap opening degree is smaller, minor diameter working roll can be used, therefore be widely used in cold
It rolls.
Application No. is the patents of " 89101393.8 ", on the basis of multi-roll mill, realize middle part pressure (in the middle part of roll
Stress), the lateral stiffness of milling train is improved, so that Strip cross section precision increases substantially, and the opening degree of roll gap can
Greatly can be small, therefore, the tower-shaped six-high cluster mill (or the mkw mill derived from) of the patent type can be used for Wide and Thick Slab and roll
Machine, not only cross section precision is high, and can be to avoid the support roller of major diameter is used as four-high mill, to be expected to dash forward
The broken widest 5.5 meters of milling trains in the world；But its whole frame can become fatal limiting factor, can because whole frame is overweight and nothing
Method manufacture or transport.
