Abstract
The utility model relates to a dummy ingot device for realizing multi-furnace continuous casting, which comprises a cylindrical plug (1), a water opening (2) of a pouring box, a fire resistant fiber board (4) arranged between a sliding board (3) of the pouring box and a sliding board (5) of a crystallizer and a dummy ingot rod (9) arranged in a copper sleeve (10) of the crystallizer. A pad board (7) the diameter of which is smaller than that of the dummy ingot rod (9) and asbestos cloth (8) the diameter of which is bigger than that of the dummy ingot rod (9) are arranged on the dummy ingot rod (9) for sealing. A bolt (6) of the dummy ingot rod is arranged on the dummy ingot rod (9) and is divided into two sections. The bolt on the front section is thin and the bolt on the back section is thick, and the movable connecting distance is adjustable.
Description
The utility model system refers in particular to the dummy ingot device that horizontal casting is realized the above continuous casting of two stoves about a kind of dummy ingot device that can realize many stoves continuous casting.
In view of the electric arc table number that China most of medium and small electric furnace steel mill has less; Electric arc furnace smelting control cycle time is inaccurate in addition, causes and will realize many stoves continuous casting difficulty.Particularly those little steel mills that have only 1-2 platform electric arc furnaces last behind the horizontal caster because can not realize two stoves on continuous casting, produce straight carbon steel, single stove continuous-cast blank cost height, of poor benefits; Produce special steel and will increase a series of measures such as going up refining, protection cast molten steel temperature in tundish, electromagnetic agitation, roll up investment.Because of shortage of funding, so after most of level is advanced casting machine test manufacture, still adopt the horizontal casting molten steel to open to water to enter the technology that promptly opens casting behind the tundish and can not form large-scale production.Not only can not embody the superiority of horizontal casting new and high technology, even influence hinders the continuation development of this technology.
The purpose of this invention is to provide a kind of dummy ingot device that can realize many stoves continuous casting simple in structure, it cooperates the continuous casting that can realize that two stoves are above with existing equipment, can improve lumber recovery, and can reduce cost.
Use a kind of special dummy ingot device that can realize many stoves continuous casting to achieve these goals, this device comprises:
Plunger (1) and middle water containing opening (2);
The flame-retardant fibre board of between tundish slide plate (3) and crystallizer slide plate (5), installing (4);
Dummy bar (9) is loaded in the crystallizer copper sleeve (10), and backing plate (7) than dummy bar (9) the diameter big asbestos cloth (8) littler than dummy bar (9) diameter is contained on the dummy bar (9), is used for sealing;
Dummy ingot bolt (6) is installed on the dummy bar (9), is divided into two sections, and the leading portion screw rod is thinner, and the back segment screw rod is thicker, is drilled with steam vent on it, and can regulate the loose joint distance.
The utility model has the advantages that: simple in structure, cost is low, implements easily.Not only can satisfy the above continuous casting of two stoves, reduce the continuous casting cost; And since the interior continuous casting of molten steel of tundish liquid level height in early stage, the static pressure height, temperature evenly helps improving steel billet and is mingled with, rimhole, and middle crack, internal flaws such as shrinkage porosite improve lumber recovery; Help bringing into play horizontal continuous casting technology in the economic benefit of little steel mill and further popularization.
Below in conjunction with drawings and Examples the utility model is further described
Fig. 1 is many stoves of the utility model continuous casting dummy ingot apparatus structure schematic diagram.
Among the figure, 1, plunger, 2, middle water containing opening, 3, the tundish slide plate, 4, flame-retardant fibre board, 5, the crystallizer slide plate, 6, the dummy ingot bolt, 7, backing plate, 8, asbestos cloth, 9, dummy bar, 10, crystallizer copper sleeve.
Embodiment
As shown in Figure 1, this many stoves continuous casting dummy ingot device comprises plunger (1) and middle water containing opening (2); Between tundish slide plate (3) and crystallizer slide plate (5), flame-retardant fibre board (4) is installed; Dummy bar (9) is loaded in the crystallizer copper sleeve (10), is contained on the dummy bar (9) than the backing plate (7) of the little 2-3mm of dummy bar (9) diameter diameter and than the asbestos cloth (8) of the big 5-6mm of dummy bar (9) diameter, is used for sealing; Dummy ingot bolt (6) is installed on the dummy bar (9), is divided into two sections, and the leading portion screw rod is thinner, and the back segment screw rod is thicker, is drilled with steam vent on it, can regulate the loose joint distance.Plunger (1) is made by the lightening fire resistant material, and its diameter is less than middle water containing opening (2) diameter 0.5-1mm, and length to diameter ratio is 1: 1: 2.
Its concrete implementing process is:
Before one heat steel is prepared tapping, after plunger (1) is coated with full Instant cement mud and blocks baked middle water containing opening (2), dummy bar is sent into crystallizer copper sleeve (10), and install asbestos cloth (8), the back segment of backing plate (7) and dummy ingot bolt (6); After having measured the dummy ingot device and pushing the required mobile distance of middle water containing opening (2) passage open, dummy bar (9) is returned to crystallizer copper sleeve (10) tail end to be fixed up, install crystallizer slide plate (5) then, install the leading portion of dummy ingot bolt (6) again, regulate the length distance.Treat that the first stove molten steel prepares to open when watering tundish slide plate (3) and crystallizer slide plate (5), to the first stove molten steel being injected tundish after connecting, start electric inductor and be incubated with flame-retardant fibre board (4) sealing; After treating that the second stove molten steel possesses two stove continuous-casting conditions, drive dummy bar (9) and push plunger (1) in middle water containing opening (2) passage open, and make it come-up and promptly start continuous casting, thereby realize the above continuous casting of two stoves.
Claims (4)
