Abstract
The utility model relates to the technical field of refractory bricks, in particular to a refractory brick for reducing rotational flow of molten steel, which comprises a stopper brick and a nozzle brick seat, wherein the stopper brick and the nozzle brick seat are matched, the molten steel is blocked when the stopper brick and the nozzle brick seat are tightly attached, a gap is generated when the stopper brick is lifted by a stopper rod, the molten steel flows into a central flow passage of the nozzle brick from the gap, and at least three vertical fins A are uniformly distributed at a liquid inlet at the top of the nozzle brick seat along the axis; the utility model provides the quality of high foundry goods.
Description
Technical Field
The utility model relates to a resistant firebrick technical field specifically is a resistant firebrick that alleviates molten steel whirl.
Background
In the actual pouring process of the existing pouring ladle and the tundish for continuous casting, molten steel rapidly flows downwards from a central flow channel of a nozzle pocket brick to form a swirl in the ladle, and the strong swirl can bring non-metallic inclusion and slag inclusion floating up in the molten steel into the molten steel, so that the casting product at the lower section has the defect of irrecoverable property, and the performance of the steel is reduced and even scrapped when the steel is serious.
Disclosure of Invention
The utility model aims at providing a refractory brick that alleviates the molten steel whirl is provided in order to produce the whirl when solving present ladle pouring and bring impurity into the molten steel in and get into the foundry goods product and cause the defect.
The utility model has the following concrete scheme: the utility model provides a alleviate resistant firebrick of molten steel whirl, includes cock brick and nozzle brick cup, cock brick and nozzle brick cup mating reaction, and the molten steel is plugged up when cock brick and nozzle brick cup are closely laminated, and the cock brick produces the clearance when promoted by the stopper stick, and the molten steel flows in the central runner of nozzle brick cup from the clearance, the top inlet port department of nozzle brick cup has at least three vertical fin A along the axis equipartition.
The upper end outer wall of chock brick has quantity and the equal fin B of fin A along the axis equipartition, fin A and fin B staggered arrangement when chock brick and mouth of a river brick cup are closely laminated.
The distance between the top of the fin A and the plane of the inlet of the nozzle brick cup is 5-20 cm.
The working principle of the utility model is as follows: adopt the utility model discloses resistant firebrick pouring, the production of whirl that has significantly reduced under the guide effect of fin when the molten steel flows to the central runner of mouth of a river brick cup to reduce impurity and pass through in the runner gets into the foundry goods product.
Compared with the prior art, the utility model has the following advantages: greatly reducing the swirling force, reducing the impurities entering the casting product, avoiding the product defect caused by the impurities and improving the product quality.

FIG. 2 is a top view of FIG. 1;
FIG. 3 is a view A-A of FIG. 2;
FIG. 4 is a schematic diagram of a prior art configuration;
in the figure: 1-ladle, 2-nozzle pocket brick, 21-central flow channel, 3-fin A, 3 a-fin B, 4-stopper brick and 5-stopper rod.
Detailed Description
Referring to fig. 1-3, the embodiment includes a stopper brick 4 and a nozzle holder brick 2 installed in a ladle 1, the stopper brick 4 cooperates with the nozzle holder brick 2, molten steel is blocked when the stopper brick 4 is closely attached to the nozzle holder brick 2, a gap is generated when the stopper brick 4 is lifted by a stopper rod 5, the molten steel flows into a central flow channel 21 of the nozzle holder brick 2 from the gap, and six vertical fins a3 are uniformly distributed at a top liquid inlet of the nozzle holder brick 2 along an axis.
Six fins B3a are evenly distributed on the outer wall of the upper end of the chock brick 4 along the axis, and the fins A3 and the fins B3a are arranged in a staggered mode when the chock brick 4 is tightly attached to the nozzle holder brick 2.
In this embodiment, the distance between the top of the fin A3 and the liquid inlet plane of the nozzle brick cup 2 is 10 cm.
