The specific embodiment
As shown in Figure 1, two vibration unit vibrating mechanisms of existing bloom or large round billet conticaster are inner arc side and the outer arc sides that is arranged in conticaster by two vibration units 1.
The upper end of two vibration units 1 is supported conticaster crystallizer 3 jointly, make conticaster crystallizer 3 be positioned at conticaster magnetic stirrer 4 and continuous casting machine fan-shaped segment 5 directly over.
The structure of two vibration units 1 is identical, all is to be made of frame-type fixed rack 101, box vibration stand 102, hydraulic cylinder 104, flexible jointing-rod 105 and guide plate 103.
Fixed rack 101 is inserted in the lower end of vibration stand 102, and the upper end is exposed and is provided with the bolt that is connected with conticaster crystallizer 3.
The cylinder body end of hydraulic cylinder 104 is fixed on the internal cavities of fixed rack 101 by flange, the piston rod of hydraulic cylinder 104 is connected by the flange in the bottom of flexible jointing-rod 105 with vibration stand 102.
The fixed rack 101 of two vibration units 1 is fixed by bearing 2 and the basis of conticaster respectively, vibration stand 102 upper ends are fixed with the both sides of conticaster crystallization 3 respectively by bolt, two hydraulic cylinders 104 are synchronized with the movement, drive 102 motions of two vibration stands, thereby jointly drive the motion of conticaster crystallizer 3.
The force direction of 104 pairs of vibration stands 102 of hydraulic cylinder is the lines in vertical flexible jointing-rod 105 tie points and the conticaster outer arc center of circle.
The deficiency of two vibration unit vibrating mechanisms of existing bloom or large round billet conticaster is only in the side of two vibration units 1 away from conticaster crystallizer 3, to be connected and fixed the top and bottom of stand 101 and vibration stand 102 by guide plate 103.
To be vibrated for a long time impact forces larger because vibration unit 1 is near a side of conticaster crystallizer 3, and guide support is on the weak side, thereby cause the vibration stand 102 of two vibration units 1 all to move and crooked situation to the crystallizer lateral deviation, this situation not only can cause conticaster crystallizer 3 guiding accuracy variation, also can cause increasing with the be rigidly connected horizontal force of flexible jointing-rod 105 of hydraulic cylinder 104 of vibration stand 102, also can cause flexible jointing-rod 105 to fracture when serious or the damage of hydraulic cylinder 104, affect the service life of vibration unit 1.
Such as Fig. 2, Fig. 3 and shown in Figure 4, in order to overcome the deficiency of the two vibration unit vibrating mechanisms that have bloom or large round billet conticaster now, existing vibration unit 1 is improved:
In the side of two vibration units 1 near conticaster crystallizer 3, be connected and fixed the upper end of stand 101 and vibration stand 102 by guide plate 103, the guide plate 103 that installs additional adopts double-deck guide plate.
As shown in Figure 5, the layout of two vibration unit vibrating mechanisms of improved bloom or large round billet conticaster is constant, still guarantee conticaster crystallizer 3 be positioned at conticaster magnetic stirrer 4 and continuous casting machine fan-shaped segment 5 directly over, simultaneously the vibration unit 1 of two improveds lays respectively at conticaster inner arc side and outer arc side.
After mode more than having adopted was improved, the technical indicator of two vibration unit vibrating mechanisms of this bloom or large round billet conticaster was as follows:
Imitative arc guide to precision be the horizontal direction beat≤± 0.10mm;
Edge casting flow path direction beat≤± 0.15mm;
Inside and outside arc unit phase difference≤1 °;
Applicable vibration frequency≤250 times/minutes.
During work, the hydraulic cylinder 104 of two vibration units 1 all with the electric-control system conducting of conticaster, by computer synchronous control, by the setting to two hydraulic cylinder 104 strokes, the conticaster crystallizer 3 of realizing being installed on above them pumps by the curve law that the continuous casting steel machine production requirement is set on the conticaster arc radius.
In conticaster crystallizer 3 motion processes, three groups of both sides vibration unit 1 double-deck guide plates 103 can make crystallizer do imitative arc motion by the arc radius of setting, and play prevent askew, turn round, partially, the effect such as pendulum.
The guide plate 103 that installs additional effectively guaranteed vibration unit when vibration accurately, for the steady operation of conticaster crystalline solid provides guarantee, the double-deck guide plate that adds has simultaneously been shared stressed effectively, has prolonged the life-span of vibration unit.
The parts that the present embodiment is not described in detail and structure belong to well-known components and common structure or the conventional means of the industry, here not one by one narration.
