Abstract
Disclosed is a thin slab continuous casting tundish immersed nozzle centring frame which belongs to fittings of continuous casters and particularly relates to a nozzle centring device for a thin slabcontinuous casting tundish. The device is characterized in that a vertical supporting frame and a horizontal supporting frame are perpendicularly connected, and a supporting rod is slantingly arrangedbetween the vertical supporting frame and the horizontal supporting frame; hangers disposed on the vertical supporting frame are connected with screw bolts arranged on the tundish; a clamping seat with an elastic clamp is arranged in the front of the horizontal supporting frame, and a tundish immersed nozzle is clamped in the elastic clamp and perpendicularly centred with a crystallizer. When thenozzle is installed, the hangers are fixedly mounted on the preset screw bolts of the tundish to adjust the vertical supporting frame, the horizontal supporting frame and the elastic clamp to reach set positions, and the tundish immersed nozzle clamped by the elastic clamp is perpendicularly centred with a crystallizer. The thin slab continuous casting tundish immersed nozzle centring frame has the advantages of easy centring in nozzle installation, convenient installation, high working efficiency, effectively control for the extension depth of the nozzle into the crystallizer and the properposition inside a cross section, high centring precision of the nozzle, stable molten steel flow field, good quality of casting slabs and smooth casting.
Description
Technical field
The utility model belongs to the conticaster accessory, relates in particular to sheet blank continuous casting tundish water nozzle centralising device.
Background technology
The submersed nozzle of sheet blank continuous casting is located on the tundish, requires the mouth of a river very accurately to insert in the crystallizer during installation, and is stable to guarantee molten steel flow field, casting smoothly.Current still do not have a mouth of a river centralising device, the mouth of a river is installed must not relies on the installation personnel perusal, and position, the manual setting mouth of a river makes its vertical insertion in crystallizer.Its defective is: eyes are observed, and easily produce error, about manual operations is carried out the mouth of a river, about and before and after adjust, the consumption time is long, inefficiency; The position is difficult to adjust precisely, and the easy and crystallizer generation deflection of middle water containing opening causes molten steel flow field instability in crystallizer, slab quality is poor, and when deflection was serious, the mouth of a river can't be inserted in the crystallizer, can't open and water, influence whole C SP Production Line and carry out smoothly.
Summary of the invention
In order to overcome the defective that prior art exists, the purpose of this utility model provides a kind of sheet blank continuous casting tundish submersed nozzle centering frame, when the tundish submersed nozzle is installed, adopt the centering frame, the bag intrusive mood mouth of a river and crystallizer vertical centering in making, the position is accurate, guarantees that molten steel flow field is stable in the crystallizer, and casting is produced and carried out smoothly.
Sheet blank continuous casting tundish submersed nozzle centering frame is a frame structure, and characteristics are that this centering frame vertically is connected with horizontal stand by vertical supports, also tiltedly establish support bar between the two stands, gain in strength; Establish hangers on the vertical supports, corresponding with the bolt of establishing on the tundish; Establish the holder of band elasticity folder before the horizontal stand, the tundish submersed nozzle is clamped in the elasticity folder, with the crystallizer vertical centering.
The utility model further improves, described vertical supports connects and composes by montant arranged side by side is vertical with cross bar, hangers is fixed on the cross bar two ends, vertical spiral range regulator is established in the montant middle and upper part, rotating vertical can be regulated montant length to range regulator, goes into the degree of depth in the crystallizer to adjust the water cutting of tundish immersion.
Another improvement of the utility model, described horizontal stand vertically is connected with crosspiece, holder by parallel horizon bar arranged side by side, the horizon bar middle front part is established the flat spin range regulator, rotate horizontal range regulator, can adjust the length of level frame, the elasticity folder can move forward and backward, and adjusts the tundish intrusive mood mouth of a river and moves forward and backward to desired location; Holder is established elongated slot, and elasticity is pressed from both sides by in the elongated slot that is bolted to holder, and elasticity folder move left and right is adjusted in the position of mobile bolt in elongated slot, makes tundish submersed nozzle move left and right to desired location.
Last improvement of the utility model, described elasticity folder is the rubber folder of opening rectangle, in the tundish submersed nozzle clamping rubber folder.During installation, hangers is packed on the default bolt of tundish, adjusts vertical frame, level frame and elasticity folder to the position of setting, and under the clamping of tundish submersed nozzle elasticity folder, is provided with the crystallizer vertical centering.
Compared with prior art, advantage is: when middle water containing opening was installed, the mouth of a river is easy to centering, and was easy for installation, high efficiency; Effectively the degree of depth and the desired location in the crystallizer cross section of crystallizer, middle water-coating port vertical centering precision height are stretched in the control mouth of a river; Molten steel flow field is stable, and slab quality is good, and casting is produced and carried out smoothly.
Description of drawings
The utility model is described in further detail for the contrast accompanying drawing below.
1. Fig. 1 is a sheet blank continuous casting tundish submersed nozzle centering shelf structure schematic diagram.
2. Fig. 2 is the side view of Fig. 1.
3. Fig. 3 is that the A of Fig. 1 is to view.
The specific embodiment
By Fig. 1, Fig. 2 and Fig. 3 as can be seen, sheet blank continuous casting tundish submersed nozzle centering frame vertically is connected with horizontal stand 2 by vertical supports 1, tiltedly establish support bar 3 between vertical supports 1 and the horizontal stand 2, establish hangers 4 on the vertical supports 1, establish holder 5 before the horizontal stand 2, the rubber folder 6 of opening rectangle is fixed on the holder 5.
By Fig. 1, Fig. 2 as can be seen, vertical supports 1 comprises montant 8 and 9, two parallel montants arranged side by side of cross bar, 8 middle parts, promptly with establish vertical spiral range regulator 10 more than support bar 3 tie points; The two ends of two side by side parallel cross bars 9 are established hangers 4, two perpendicular poles 8 and vertically are connected with two cross bars 9; Two montants 8 times and 2 vertical connections of horizontal stand.
By Fig. 1, Fig. 2 and Fig. 3 as can be seen, horizontal stand 2 comprises horizon bar 11, crosspiece 12, holder 5, and two ends are two parallel horizon bars 11 side by side, and front middle part is established flat spin range regulator 13, parallel crosspiece 12 and holder 5 and 11 vertical connections of horizon bar arranged side by side, rubber folder 6 is fixed in the holder 5.In order to increase support body intensity, under the vertical spiral range regulator 10 of vertical bar 8 and the left side of the flat spin device 13 of horizon bar 11 establish support bar 3, structure triangle rock-steady structure, support body is firm.
