Abstract
The utility model discloses an online weighing device for molten steel in a continuous casting tundish, and belongs to the technical field of continuous casting production facility. The online weighing device is used for online weighing of molten steel in the continuous casting tundish during production of continuous billet casting for metallurgy and steelmaking. The technical scheme includes that the online weighing device comprises a carrier plate, a weighing box, a weighing sensor, a pressure bearing head and a junction box, wherein the weighing box is fixed on the carrier plate, the weighing sensor is positioned in the weighing box and is fixed on the carrier plate through bolts, the pressure bearing head is fixedly mounted on the top of the weighing sensor, the top surface of the pressure bearing head is matched with a trunnion of the continuous casting tundish in terms of shape, and the weighing sensor is connected with the junction box through a conductor wire. The molten steel of the continuous casting tundish is weighed online by the weighing sensor, and accordingly accuracy and fastness in weighing are achieved. The pressure bearing head is manufactured according to the shape of the trunnion of the continuous casting tundish, and is uniform and stable in load bearing during weighing. In addition, the online weighing device is simple in structure, low in investment, reliable in operation and convenient to mount and maintain; and parts of the online weighing device is easy to process.
Description
Technical field
The utility model relates to the weighing device in the metallurgical steel-making continuous casting base casting production, belongs to continuous casting production facility technical field.
Background technology
For many years metallurgical steel-making continuous casting molten steel tundish carries out online weighing and continues to use regulations and parameters principle mode the continuous casting steel tundish is weighed, the shortcoming of this weighting manner is that the weighing data error is large, the degree of accuracy is low, more can not reflect timely and effectively the variation tendency of Metal in Tundish weight in continuous casting production process.Metal in Tundish weight is the important evidence that operating personnel carry out certain operations, especially the weight of Baogang's water is most important in opening when watering with quick change, and in casting cycle, directly affect the adjustment that operating personnel's centering Baogang water liquid automatic control, pulling rate are controlled, gone out the technological parameters such as tail base, so that operating personnel are difficult to instruct rapidly and accurately continuous casting production process, therefore the quality of production of continuous casting billet had a negative impact.Along with the development of producing, be badly in need of at present in the casting of continuous-cast billet process to continuous casting steel carry out accurately, online weighing timely, in order in time control exactly pouring basket liquid level and pulling rate according to the variation tendency of Metal in Tundish weight in continuous casting production process, this will solve the defective that strand exists, and significantly improves the quality of strand.
The utility model content
Technical problem to be solved in the utility model provides a kind of molten steel in bakie in continuous casting online weighing device that can accurately carry out online weighing to molten steel in bakie in continuous casting.
The technical scheme that solves the problems of the technologies described above is:
A kind of molten steel in bakie in continuous casting online weighing device, it is comprised of weight tray, the casing of weighing, LOAD CELLS, pressure bearing head, terminal box, the casing of weighing is fixed on the weight tray, LOAD CELLS is positioned at the casing of weighing, LOAD CELLS is bolted on weight tray, the top of LOAD CELLS is installed with pressure bearing head, and the shape of the end face of pressure bearing head and continuous casting tundish gudgeon is complementary, and has wire to be connected between LOAD CELLS and the terminal box.
Above-mentioned molten steel in bakie in continuous casting online weighing device, the described casing of weighing, LOAD CELLS, pressure bearing head are two covers, they are fixedly mounted on respectively the two ends of weight tray, terminal box is connected with two LOAD CELLSs respectively, and two pressure bearing heads are complementary from the shape of the continuous casting tundish gudgeon of different profiles respectively.
Usefulness of the present utility model is:
The utility model adopts LOAD CELLS that molten steel in bakie in continuous casting is carried out online weighing, has the accurately and rapidly advantage of weighing, and weighing accuracy satisfies processing parameter and reaches 0.5% requirement; Pressure bearing head is made according to continuous casting tundish gudgeon external form, and bearing load is even, stable when weighing.The utlity model has and consist of easy, parts and be easy to process, invest little, reliable operation, advantage convenient for installation and maintenance, be applicable in the continuous casting billet production process molten steel in bakie in continuous casting to be carried out online weighing and use.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Mark is as follows among the figure: weight tray 1, the casing 2 of weighing, LOAD CELLS 3, pressure bearing head 4, terminal box 5.
The specific embodiment
Show among the figure that the utility model is comprised of weight tray 1, the casing 2 of weighing, LOAD CELLS 3, pressure bearing head 4 and terminal box 6.
Two casings 2 of weighing are fixed on the weight tray 1, LOAD CELLS 3 is positioned at the casing 2 of weighing, LOAD CELLS 3 is bolted on weight tray 1, pressure bearing head 4 is bolted in LOAD CELLS 3 tops, the end face of pressure bearing head 4 is complementary from the shape of different continuous casting tundish gudgeon respectively, has wire to be connected between LOAD CELLS 3 and the terminal box 5.
The utility model can reflect the variation tendency of Metal in Tundish weight really, so that tundish weight can be intuitively effectively the stressed bogey of tundish axle that passes through act directly on the LOAD CELLS, Weighing display device directly show Metal Weight and by 4 ~ 20mA or RS232 in operation control computer demonstration Metal in Tundish weight with along with the changing trend diagram that carries out Metal in Tundish weight under the process status of continuous casting process, weighing accuracy satisfies processing parameter and reaches 0.5% requirement.
