Casting machine technical field.
Background technique
Conticaster is the important metallurgical equipment of steel mill, and Blank drawing machine and straightener are the core equipments of conticaster, throwing
Machine and straightener cooperating are sent into dummy bar in crystallizer, and after conticaster draws steel instruction issuing, Blank drawing machine passes through dummy bar
Slab is pulled out from crystallizer, and when dummy bar head and slab head junction are by below the straightening roll of straightener,
Straightening roll is depressed under the action of aligning cylinder, disengages slab and dummy bar, while straightener aligns slab.
Currently, Blank drawing machine and straightener are typically designed to whole frame, and it is combined and is withdrawal straightening machine.Conticaster is rectified
Single-point aligning or multipoint straightening are directly mostly used, such as a kind of Chinese utility model patent " independent rack jaw types of the double transmissions of up-down rollers
Withdrawal straightening machine ", application number: 20111086181.8), Chinese utility model patent " dual 5-roller frames progressive straightening withdrawal straightening machine ", application
Number: 01112954.9, utility model patent " Combined jaw-type tension straightening machine ", application number: 00223883.7, their common feature
It is:
(1) Blank drawing machine and straightener share a rack, that is, whole frame, cause its aligning section cannot be too
It is long；
(2) straightening roll of straightener is on the one hand and straightening roll is hinged, on the other hand hinged with the axis in common frame, is pressing
When lower, the pressure direction of roller and slab align the vertical of only one very little in the power that hydraulic cylinder is exported at an acute angle degree
In slab component as straightening force；
(3) straightener driving mechanism is mounted on the side of straightening roll, and transmission device self weight is larger, distance casting blank farther out, and
Slab size is smaller, and such transmission device can bring an additional unbalance loading torque to straightening roll, this unbalance loading torque is by rectifying
Straight roller acts on slab, causes aligning upper roller and aligning lower roll not parallel, and casting billet surface outer dimension deforms, and slab is run
Partially.What this phenomenon was showed when the smaller depressing force of slab size is larger becomes apparent；
(4) with the propulsion of conticaster high efficiency, slab wick-containing is inevitable very long, such as still certainly will make continuous casting using above-mentioned aligning
Machine radius is very big, this is obvious unreasonable；
(5) 3% is at least had using single-point aligning or multipoint straightening, slab internal strain.
