Abstract
The utility model provides a centering device for approaching continuous slab casting immersion nozzle: its mainly by the mouth of a river inserted hole on U -shaped frame, the U -shaped frame, connect at the locating plate between the board of U -shaped frame both sides, connect the handle of connecting on centering pointer on U -shaped rest base board central line, the U -shaped rest base board under the centering pointer and constitute. The utility model discloses removing the in -process at the mouth of a river, making the left and right sides and front and back centering at the mouth of a river rapidly, the error of centralization <= 1mm can guarantee that the stability of casting blank quality and centering are accurate, quick, convenient, and simple structure, easy operation.
Description
Technical field
The utility model relates to a kind of steel-making centralising device, specifically belongs to a kind of centralising device for sheet blank continuous casting submersed nozzle.
Background technology
Crystallizer is that iron and steel is stablized, last controlling unit efficiently, in clear production flow process, is also the link of most critical.Sheet blank continuous casting process molten steel flows into crystallizer by submersed nozzle.In order to ensure that mold liquid level is stablized, the problem such as liquid fluctuating and slag does not occur, and submersed nozzle must be arranged on the center of crystallizer internal cavity.
Sheet blank continuous casting is efficient with it, low cost and obtain the attention on domestic metallurgical boundary.Thin slab mold submersed nozzle is " ox muzzle " dress of flat bilateral perforate, and mouth of a river width is large, usually between 230-420mm, far wider than the conventional submersion mouth of a river.Continuous casting starts in the process of pouring into a mould, the mouth of a river is arranged on tundish car, slowly moved to crystallizer by side, reach after above crystallizer internal cavity, control before and after tundish car by site operation personnel and left and right fine setting centering, then drop in crystallizer internal cavity, open top stopper, molten steel enters in crystallizer.Whether Mold flowing stablizes; whether flow field is reasonable; directly related with the centering at the mouth of a river; rational crystallizer flow field can make field trash and bubble floating in molten steel; to prevent slag, covering slag is impelled to melt good, otherwise; then can cause slag, slab is cracked, quality and the production accident such as bleedout.
Because submersed nozzle is before opening and watering, need to toast, reach after more than 1000 DEG C, just satisfiedly open the condition of watering.Open in the process of watering, when the mouth of a river moves to above crystallizer, temperature is very high, and the liquid level of molten steel in tundish constantly rises in addition, and therefore, the time that permission site operation personnel adjusts immersible ladle nozzle centering is very short.At present, the method that site operation personnel adjusts mouth of a river centering mainly contains following two kinds:
1, empirical method: make marks in crystallizer wide midpoint, then in the process of mouth of a river movement, carry out centering by rule of thumb; And front and back centering generally can only judge with naked eyes, it exists, and the centering time is long, and efficiency is low, and also there is deviation, i.e. the poor accuracy of centering.
2, setting method is shifted to an earlier date: in calculating, hired car is to the distance of crystallizer central point, by setting displacement in advance, once moves into place when opening and watering.Hired car during fixed point is mobile, needs centering hired car accurately to measure with the distance of crystallizer central point early stage, the high length consuming time of difficulty, in addition, whether accurately can move into place, also be subject to the impact of middle hired car equipment and various working sensor state, often do not reach ideal effect.
Utility model content
The deficiency overcoming prior art existence that the utility model exists for prior art, there is provided a kind of in the moving process of the mouth of a river, left and right and the front and back centering at the mouth of a river can be made rapidly, the error of centralization≤1mm, can ensure the stable of slab quality and centering accurate, quick, convenient, and structure is simple, the easy-operating centralising device for sheet blank continuous casting submersed nozzle.
Realize the technical measures of above-mentioned purpose:
For a centralising device for sheet blank continuous casting submersed nozzle, it is: its primarily of the mouth of a river insert port on U-shaped frame, U-shaped frame, be connected to location-plate between U-shaped frame biside plate, be connected in U-shaped frame base plate center line to pointer, to the handle composition that the U-shaped frame base plate immediately below pointer connects.
It is: at handle and U-shaped frame base plate, and be all connected with enhancing bar between the side plate and base plate of U-shaped frame.
It is: the opening degree of mouth of a river insert port is greater than mouth of a river width and is no more than 5mm; The center line of pointer is overlapped with mouth of a river center line.
Feature of the present utility model: in the moving process of the mouth of a river, can make rapidly left and right and the front and back centering at the mouth of a river, the error of centralization≤1mm, can ensure the stable of slab quality and centering accurate, quick, convenient, and structure is simple, easy to operate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 be Fig. 1 a left side depending on or the structural representation looked of the right side;
Fig. 3 is the utility model using state figure;
In figure: 1-U-shaped frame, 2-mouth of a river insert port, 3-location-plate, 4-to pointer, 5-handle, 6-strengthen bar.
Detailed description of the invention
Be described further below in conjunction with accompanying drawing:
A kind of centralising device for sheet blank continuous casting submersed nozzle: its primarily of U-shaped frame 1, the mouth of a river insert port 2 be formed on U-shaped frame 1, adopt welding or the location-plate 3 of riveting between U-shaped frame 1 biside plate, adopt screw thread or be welded to connect in U-shaped frame 1 base plate center line to pointer 4, to U-shaped frame 1 base plate immediately below pointer 4 adopting screw thread or the handle 5 that is welded to connect form.
At handle 5 and U-shaped frame 1 base plate, and be all welded with between the side plate and base plate of U-shaped frame 1 and strengthen bar 6, to strengthen intensity, raising life cycle.
The opening degree of mouth of a river insert port 2 is greater than mouth of a river width and is no more than 5mm; The center line of pointer 4 is overlapped with mouth of a river center line.
The installation site of location-plate 3 in U-shaped frame 1 just in time falls thereon to make front, the mouth of a river.
In operation of the present utility model, the mouth of a river is closely stuck in the space of location-plate more than 3, to ensure invariant position in the moving process of the mouth of a river, namely makes the center line of mouth of a river business newly keep overlapping with to the center of pointer 4 all the time.
This detailed description of the invention is only the best and exemplifies, the restricted enforcement not to technical solutions of the utility model.
