Abstract
A kind of conticaster heavy reduction casting flow guide device, is characterized in that: it is fastening that upper frame and underframe are clamped hydraulic cylinder, is respectively provided with guide rail inside upper and lower framework.Top working roll is arranged on below lift beam, and upper lift beam is hinged on upper frame by hydraulic cylinder for reduction system, is the gap that is slidably matched, is provided with position sensor in hydraulic cylinder for reduction system between upper lift beam and upper rail.Bottom working roll is arranged on above lower lift beam, and lower lift beam is hinged on underframe by pressing hydraulic cylinder, and lower is also the gap that is slidably matched between lift beam and lower guideway, presses in hydraulic cylinder and is also provided with position sensor.Transmission device is connected with upper and lower working roll respectively.The utility model by casting of the prior art stream guide section and milling train by being combined into one, compact conformation, the internal rarefaction of strand is organized compacting, make conventional casting machine can produce superior in quality super-thick steel plate, thus change the steel plate technological process of production, reduce Medium and Heavy Plate Rolling passage, reduce the production cost of medium plate.
Description
Technical field the utility model belongs to conticaster technical field, particularly medium slab caster group.
Background technology current steel mill medium slab caster produce casting blank inner organization shrinkage cavity, the defect such as loose, affect the quality of strand, must at jobbing sheet-rolling mill heavy reduction, through multi-pass rolling, defects such as organizing shrinkage cavity, loosen could be eliminated, produce high-quality sheet material, but this can make steel plate thickness specification quantity reduce.If through the continuous casting billet of heavy reduction casting stream device rolling, be rolled in casting blank solidification end strand core mushy zone, then can seam strand core, such strand carries out few passes just can produce qualified middle plate, the quantity of steel plate thickness specification increases, and saves the energy.
Utility model content is in order to overcome the defect existed in the common casting machine of prior art, grasp the mechanical performance improving continuous casting billet, improve Plate Rolled quality, plate thickness specification in increase, reduce the object of rolling pass economize energy, the utility model proposes following technical scheme: a kind of conticaster heavy reduction casting flow guide device, is characterized in that: it is fastening that the upper frame be arranged symmetrically with up and down and underframe are clamped hydraulic cylinder, be provided with upper rail inside upper frame, inside underframe, be provided with lower guideway.Top working roll is arranged on below lift beam, and upper lift beam is hinged on upper frame by hydraulic cylinder for reduction system, is the gap that is slidably matched, is provided with position sensor in hydraulic cylinder for reduction system between upper lift beam and upper rail.Bottom working roll is arranged on above lower lift beam, and lower lift beam is hinged on underframe by pressing hydraulic cylinder, lower lift beam (and be also the gap that is slidably matched between lower guideway, press in hydraulic cylinder and be also provided with position sensor.Transmission device is connected with top working roll and bottom working roll respectively.In the below of upper lift beam, top backing up roll is installed, in lower lift beam, also lower support roll is installed.
Adopt the utility model of technique scheme casting stream guide section of the prior art and rolling function to be combined as a whole, both achieved continuous casting flow guider and there is interchangeability, there is again milling train function.One time drafts is 10% of slab thickness, and the internal rarefaction of strand is organized compacting, makes conventional casting machine can produce the excellent super-thick steel plate of internal soundness.This casting flow guide device is reasonable in design, compact conformation, and improve the mechanical performance of continuous casting billet, the continuous casting billet of extrusion can meet the strength character requirement of steel plate, thus changes the steel plate technological process of production, reduces the production cost of steel plate.
Accompanying drawing illustrates that the utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the utility model conticaster heavy reduction casting flow guide device front view;
Fig. 2 is the cross-sectional schematic along A-A line in Fig. 1;
