Abstract
The invention discloses great pressure-down sector section equipment. In the inner arc frame assembly process, each roller is fixed to an independent movable beam corresponding to each roller, the movable beam is connected with an inner arc frame by hydraulic cylinders which are hinged to two ends of the movable beam; an inner arc frame guide plate is arranged in the inner arc frame; the hydraulic cylinders are connected with a displacement control and pressure system; each roller which is assembled on an outer arc frame is relatively fixed to the outer arc frame, and the inner arc frame and the outer arc frame are assembled by bolts and are mutually connected and fixed to the upper end face of an outer arc frame side frame; a driving roller is arranged on the movable beam which is located on the middlemost position of the equipment, and the side end of the bottom of the outer arc frame is connected with an automatic steam communication device; when each pressing-down roller receives a current pressing-down stroke instruction, the roller instantaneously reaches an instruction position rapidly by the flexibility control of the hydraulic cylinders, the great pressure-down requirement at the position is realized, and each pressing-down roller in a sector section is subjected to great pressure. The great pressure-down sector section equipment has the characteristics that the pressure-down range is wide, the accuracy is high, and the control on a single roller is realized.
Description
Technical field
The present invention relates to metallurgical continuous casting equipment technical field, particularly sector section equipment under a kind of weight.
Background technology
Because metal solidification process must be followed volume contraction and choosing point crystallization, under conventional continuous-casting conditions, casting blank solidification end certainly leads to the defect such as center porosity and center segregation; Be subject to the impact of composition and casting blank solidification characteristic, in the time of the strand of casting section (>=300mm) and steel grade, the above-mentioned internal flaw problem of strand is more outstanding; If solidify the contraction of latter end bulge or roll gap and do not get caught up in the solidification shrinkage distortion of base shell, the internal soundness that more makes strand is worsened more.
In order to eliminate center segregation that heavy slab solidification shrinkage causes and loose, avoid the generation of the remaining liquid phase feeding phenomenon of solute, start to adopt the inferior technology of weight to improve.Under the weight that increases drafts, in technical study, also the equipment that can meet heavy soft reduction process is researched and developed in the industry both at home and abroad.
Summary of the invention
In order to overcome the defect of prior art, the object of the present invention is to provide sector section equipment under a kind of weight, can realize fan-shaped section inner arc roller moves up and down separately, control respectively the gap between the corresponding roller of its outer arc, according to technique needs, the independent adjusting control function of realizing every pair of segment roll gap, meets the requirement under continuous casting weight.
In order to achieve the above object, technical scheme of the present invention is:
Sector section equipment under a kind of weight, comprises interior arc frame assembling and the assembling of outer arc frame; In interior arc frame assembling, each the first roller 11-1 is fixed on each self-corresponding independent walking beam 4, walking beam 4 is connected with interior arc frame 1 by the hinged hydraulic cylinder 5 in two ends, is provided with interior arc frame guide plate 3 in interior arc frame 1, and hydraulic cylinder 5 is connected with displacement control and pressure system 6; Every the second roller 11-2 of outer arc frame assembling is relative fixing with outer arc frame 2, interior arc frame 1 and outer arc frame assembling 2 are interconnected and fixed the upper end surface of arc frame bogie side frame 8 outside by bolt 7, be positioned on the middle walking beam of equipment 4 and be provided with driven roller 9, outer arc frame 2 bottom portion side ends connect automatic aqueous vapor engaging means 10.
Advantage of the present invention: 1) depress roller in the time receiving its current drafts instruction for every, fast by the extension and contraction control of hydraulic cylinder 5, make the instantaneous arrival location of instruction of roller, realize requirement under the weight at this place.2) under weight, every in fan-shaped section depresses roller, all can according to separately depress instruction follow-up adjustment, relatively there is no this fan-shaped section by roller press function, there is the scope of depressing wide, the degree of accuracy is high, is convenient to the feature of single control.
Brief description of the drawings
Accompanying drawing is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, structural principle of the present invention and operation principle are described in detail.
With reference to accompanying drawing, sector section equipment under a kind of weight, comprises interior arc frame assembling and the assembling of outer arc frame, in interior arc frame assembling, each the first roller 11-1 is fixed on each self-corresponding independent walking beam 4, walking beam 4 is connected with interior arc frame 1 by the hinged hydraulic cylinder 5 in two ends, in interior arc frame 1, be provided with interior arc frame guide plate 3, hydraulic cylinder 5 is connected with displacement control and pressure system 6, independent walking beam 4 slides up and down 3 of interior arc frame guide plates with the synchronization telescope of two ends hydraulic cylinder 5 with roller, the upper-lower position of realizing every roller regulates, independent instant adjusting of every the second roller 11-2 space D that displacement control can realize the every relative outer arc frame 2 of the first roller 11-1 in interior arc frame assembling with pressure system 6, thereby provide hardware supported for realizing heavy press function, every the second roller 11-2 of outer arc frame assembling is relative fixing with outer arc frame 2, interior arc frame 1 and outer arc frame assembling 2 are interconnected and fixed the upper end surface of arc frame bogie side frame 8 outside by bolt 7, be positioned on the middle walking beam of equipment 4 and be provided with driven roller 9, driven roller 9 can be realized throwing function under the effect of its Power Drive Unit, and outer arc frame 2 bottom portion side ends connect automatic aqueous vapor engaging means 10.
Operation principle of the present invention: on strand cross section, do not solidify while reaching proper proportion with the ratio of solidifying part, carry out ironed according to suitable drafts to strand, time strand heart portion not solidify molten smelting mobile to some extent, and the easily dendrite of generation of destruction, solidification shrinkage space is filled in molten smelting, improves strand heart portion mass defect, improves the internal soundness of strand.According to requirement under weight, the space D between the every pair of rollers of timely adjustment is controlled the slab thickness passing through, and is the Core Feature of fan-shaped section under weight.The present invention realizes this function by following process:
According to the roller (11-1 on each walking beam 4, 11-2) relative strand position, for current strand translational speed, the intensity of cooling water, the conditions such as steel grade, by the analytical calculation of proprietary casting blank solidification software for calculation, immediately provide the space D (being also by the slab thickness between every pair of rollers) between every pair of rollers, and instruction is sent to and controls every pair of rollers (11-1, displacement control 11-2) and pressure system 6, the telescopic location that displacement control and pressure system 6 are controlled hydraulic cylinder 5 feeds back by its inner displacement transducer, and coordinate dedicated hydraulic, electric control system, its corresponding position of each moment of cylinder bar is controlled, to reach dynamically space D between the every pair of rollers of instant control, reach and implement control and regulation by the object of slab thickness between every pair of rollers, implement heavy press function, automatically aqueous vapor engaging means 10 are realized refrigerating function.
